    The construction industry is the UK’s biggest consumer of natural resources. The finding was revealed as part of a study by Waste Management and Reprocessors (WRAP) which works with businesses, local authorities and governments to improve recycling collections and reduce waste writes James Wilkinson, Design Team Manager at Gradient. According to WRAP, the building sector uses 400 million tonnes of material each year, resulting in an annual production of 100 million tonnes of waste. The data does nothing to assuage the notion that the construction industry’s renowned reliance on traditional practices and techniques is to the detriment of its environmental performance. The tide is turning though, and the building supply chain is bolstered by manufacturers and the like making sustainability core to their offering. Gradient is one such company. As a turnkey service supplier of flat and tapered roof insulation, each element of Gradient’s provision – from the initial client contact, to site surveys and the bespoke creation and delivery of the product itself – is aimed at minimising waste. Such is the forensic detail applied to the systems we manufacture; the amount of insulation we provide will be precisely what is needed to meet project requirements – no more, no less. This not only minimises material waste, it makes for a more cost-effective installation, which is in itself has sustainable benefit. Call-off duty As well as avoiding over-specifying materials, Gradient offers a call-off delivery service for customers. This allows bulk orders to be delivered over a period of time. Providing installers with the right amount of product when needed significantly reduces instances of unused materials being left around site to deteriorate. This ‘call-off’ system is of particular benefit in city-based construction projects where space is likely to be severely limited, and having spare materials deposited about a site poses an increasing health and safety risk, as well as accruing a costly build-up of waste. On congested sites with minimal storage room, phased delivery times also protect against the far from ideal scenario of using roofs as a convenient facility to stow unrequired items. For waterproof installers with little site space in which to manoeuvre, but with a 10,000m2 at their disposal, it’s a temptation few would find easy to resist. But leaving materials unsecure and exposed upon a roof risks damaging the items themselves, as well as the roof they are designed to protect. It also imperils other areas of a site due to the potential for materials or debris to be blown from the roof. Such an outcome could not only cause serious injury to a passing trades person or member of the public, it would likely lead to project delay and tarnishing of the reputation of the company involved. Building sustainability into design Putting sustainability at the core of tapered insulation and roof design in practical terms means initiating processes which make a difference to waste generation. At Gradient, for example, our technicians try to minimise the number of different falls on a roof. This uniform approach to design allows insulation boards unused in one area of a roof to be installed elsewhere within the application. This recycling of materials comes at zero cost to the insulation system’s overall performance, but does spare high-performance boarding from being cast to the skip. Sustainability is endemic within Gradient’s culture. Hence in terms of the design process, our technical teams are not only focused on creating a flat or tapered roofing insulation that is specific to a client’s requirements and built to last the lifespan of a building, they will challenge themselves to optimise a project’s environmental performance. The off-site manufacture of systems within a controlled environment is a major contributor to our sustainably-favourable output. For example, our single-layer tapered insulation systems arrive on site pre-bonded, thus eliminating the need for installers to adhere the boards themselves, a process which could be delayed by exterior elements causing moisture or debris to contaminate the glue, rendering it unusable. Again, seemingly minor issues such as this can parlay to increase costs which would otherwise by offset by taking a more sustainable approach to the job in hand. Don’t let sustainable working practices go to waste By creating the opportunity for waste – which also incurs expense during its transportation and safe disposal – those involved in the building supply chain throw away the chance of driving down project costs that are ultimately borne by the customer. The environment also suffers, which in the long-term affects us all if we are denied the chance to breathe cleaner, less-polluted air. It’s a situation that can be fixed if all strands of the construction industry were, like Gradient, to go one step further in striving to reduce their carbon footprint.

    Dependent on the products and materials used, a flat roof’s waterproofing should last between 20 and 40 years writes Kevin O’ Connell from the IKO Group . Good maintenance will also contribute to its performance and longevity. But which proactive steps need to be taken when a waterproofing system reaches the end of its serviceable life? Roofing purpose When deciding on a waterproofing system for a flat roof application, it’s important to consider what it’s meant to do. An appropriately-designed and correctly-installed solution will prevent a prevalence of standing water, which in-turn will protect the structural integrity of the building itself. Water carries immense weight and when left to pond, it could lead to the breakdown of the roof’s coating which will leave the roof susceptible to the UV degradation. As an example of the immense strain it can bring to bear, 1mm of water per m2 equates to 1kg. Therefore, that same level of water across a 5mm x 30m2 surface would be akin to two adults standing on a roof. Long-standing water can also promote vegetation growth in the form of plants and fungi; wildlife that can penetrate a flat roof’s surface and cause untold damage to the building itself. As well as keeping a roof dry, a good waterproofing system should ensure it achieves regulatory levels of thermal performance. In poorly insulated homes, roofs account for 25% of a building’s heat loss. It is crucial, therefore, that the insulation supplied as part of a build-up offers an effective barrier to energy escape whilst being of suitable thickness to prevent the obstruction of door and window thresholds. Its design should also take into account roofs with plant installations, walkways and safety features such as guardrails and hatch systems. Monitor to prevent major repairs Good management can be achieved by gaining anunderstanding of your roof stock. Is it old or is it new? Are there other plans for the building that could impact the roof? New windows may provide less ventilation than old ones; therefore will an extension be required to facilitate such an installation?   Prevention is better than cure, a saying that is particularly pertinent to roofing management. Neglecting to act upon tell-tale signs of a roof’s degradation can transform a seemingly minor maintenance issue into a major repair project that potentially comes at great expense to a property owner in order to keep it weathertight and its occupants safe. This worst-case scenario can be avoided by keeping a periodical look-out for signs of natural wear and tear which indicate a roof’s performance is in danger of being compromised. These visual sirens might include elements such as lap joints becoming loose or in the case of an asphalt roof, the appearance of surface lumps and creases, or even blocked outlets. Getting the balance right In terms of appropriate waterproof specification for flat roofs, property owners must strike a balance between the ‘nice’ to have, with the ‘need’ to have. To ensure this thin line is more easily navigated, it’s important to decide upon a level of spending by drawing up a budget. This should take into account future plans for the roof asset and the building itself. Engage with the experts The aforementioned issues can be overcome by engaging with roofing, waterproofing and insulation experts such as IKO Group. Our industry expertise is available to facilitate an appropriate solution for a wide range of flat and tapered roof applications. In terms of performance and cost, we have the all-round knowledge to direct clients towards the most appropriate waterproofing solution.  We understand that although hardly out of sight; roofs are out of mind for most people – it’s just not something they choose to think about. However, this shouldn’t detract from their everyday importance, and at IKO we’ve got the whole of issue of roofing design and performance covered. Early engagement will always result in a more favourable outcome.

    Figures show one-in-six construction-based workers suffers from a form of mental illness. Even more alarming is the statistic that reveals suicide kills more people in the building sector than falls from height writes Steph Palmer, BriggsAmasco Training Officer. It’s also reported that two construction workers reportedly take their own life each day. Such distressing data highlights the urgent need for roofing companies and the industry as a whole to educate employees and ensure they have the best possible support in order to recognise mental stress symptoms in themselves and colleagues. In doing so, they will be taking a vital first step to making a full recovery from the debilitating effects of anxiety and depression.  Journey As a company, BriggsAmasco is facilitating an environment that encourages, where reasonably possible, improved mental health amongst employees. This journey began in 2017 when a workshop was staged as part of the company’s annual Health and Safety forum. It was held on behalf of contract-related staff and subcontractors in order to steer individuals seeking guidance towards the appropriate mental health support. Feedback from employees who attended the workshop was extremely positive. This was particularly encouraging, as BriggsAmasco aims to create an environment and culture where staff feel comfortable discussing their psychological state, whether it is good or bad.  Employers should take into account the fact that not all workers feel comfortable raising such issues with their manager, whereas others will view it as the best avenue to getting help. Listening to workers and addressing their specific needs is vital. Any staff member that is not comfortable speaking to a BriggsAmasco representative has access to the company’s Employee Assistance Programme that is 100% confidential and deals with anything from mental health issues to financial or legal problems they may be experiencing. New employees are issued with information cards, highlighting external organisations – The Lighthouse Club, Building Mental Health – which provide support to the construction community and their families. Mental health initiative BriggsAmasco hosts each new employee at its Birmingham head office for a two-day induction that includes a presentation and discussion on its mental health strategy, devised to ensure each employee has access to at least one mental health first aider on site and within its offices. Two members of BriggsAmasco staff are Mental Health First Aid (MHFA) trained and available to deliver the courses throughout the business. Since March 2019, the company has trained 35 staff as mental health first aiders; a figure that will increase in the following year. The company’s board of directors will also undergo training in mental health awareness to help continue open conversations across the company, as proof of how seriously it takes its staff’s psychological welfare.   Mental illness has long been considered something of a taboo subject within the building industry. By bringing the issue to light through its education and training initiatives, BriggsAmasco is doing all it can to safeguard its employees’ peace of mind. Visit:https://briggsamasco.co.uk/

    The British Standards Institute (BSI) has published the BS 6229: 2018 - flat roofs with continuously supported flexible waterproof covering - code of practice – writes Martin Bidewell, Head of Technical and Product Management for Sika Roofing .   The latest guidelines, which were published in November, contain a number of changes in relation to general good practice guidance, updated terminology and definitions for flat roofs. These include an update of the previous definition for a “vapour control layer” to an “air and vapour control layer” (AVCL), as they perform two important functions. Changes now recommend avoiding the traditional cold roof construction, where the insulation is on the underside or cold side of the deck, due to the difficulty in forming an effective AVCL, cross ventilation and the subsequent increased risk of condensation. An additional “breather layer” is now shown over the insulation to provide an external air-leakage barrier and to help protect the insulation against any detrimental environmental factors. More specific reference on the minimum design and finished falls in formed gutters and a new definition for “zero falls” (roof slope between 0 and 1:80 with no back falls or ponding) is also now included. A small relaxation to minimum upstand heights at door thresholds to balconies and terraces only is adopted (following NHBC guidance) to allow designers to meet the Building Regulations for level access. For all other abutments, the waterproofing should still be terminated a minimum of 150mm from the finished roof level. Updated advice is available for the thermal design of inverted roofs, having now obtained improved practical experience of the actual performance of inverted roofs incorporating a water flow reducing layer (WFRL), designed to reduce the ‘cooling effect’ from rainwater. Interstitial condensation is covered in detail under its own standard, BS 5250, so has been removed from this standard. However, the updated code of practice does advise minimum thermal values for heated buildings (0.35W/m2K) are achieved at any point, to avoid surface condensation, all as per legislation guidance. Although it is anticipated many of the above mentioned amendments will take time to become established industry practice Martin Bidewell, Sika’s Head of Technical and Product Management, said those within the building sector should now be familiarising themselves with the code and following this updated guidance. He said: “Manufacturers, specifiers and the like should be obtaining copies of the standard. People need to understand what the detailed changes are and the affect it might have on our buildings. From here on in, companies should be doing their utmost to ensure all new designs incorporate the latest recommendations.” The code relating to flat roofs with continuously supported coverings was previously updated in 2003. Martin said the new guidelines provide more clarity for users. “The latest guidelines are more defined and help eliminate some of the grey areas that existed within the previous code,” he said. “The 2003 version really was an old standard, therefore the 2018 code brings it into line with the latest Building Regulations and other codes of practice. In my opinion, the latest guidelines are more streamlined and easier to understand, which can only be a good thing.” “The guidelines are vital to successful flat roofing,” Martin added. “The standard sets out the basics of how to properly design a flat roof. There will always be instances when the guidelines cannot be adhered to completely, particularly when the project involves the refurbishment of an existing roof. However, there should be no excuse to ignore the code in new-build scenarios. The BS 6229 code of practice is the go-to flat-roofing document, and along with relevant trade association guidance, should form the minimum standards the industry is looking to achieve for every roofing project.” For copies of BS 6229: 2018, visit: shop.bsigroup.com

    There is one major factor, the elephant that is constantly in the room that dictates almost everything that happens in the construction industry – it is called the lowest possible price. It is frequently responsible for shoddy workmanship, poor building materials and more failures than anything else. It blights the construction industry, has done for decades and in spite of many good intentions, little has changed over the years and say Proteus, one of the country’s leading waterproofing companies, there are few signs that it ever will. Every part of our business is price led and this particularly applies to roofing and waterproofing – a vital component of every building, but frequently the poor relation, possibly because much of its work is mostly out of sight and not considered quite as glamorous or as cosmetic as other parts of a building such as cladding or balconies. Without the intervention of a strong architect or a contractor unwilling to compromise, cheap will nearly always win the day. Some 80% of all specifications are changed before buildings are completed with the phrase “or similar” constantly used as justification for changing products or systems. The fact is – or similar – does not quite cut it on every occasion. There is little policing or testing of substituted products prior to installation, just a strong acceptance that the chosen alternative will do the same job and will do it just as well. Most of the time, that will be the case, but there have been many examples where projects have failed because the alternative failed to match up. Nearly every construction professional will testify and give examples where cheaper alternatives have not offered the same longevity or performance, are often more difficult or less user friendly to install, which in turn, totally negates any upfront cost savings. Proteus Waterproofing, like most companies in this sector of the roofing market, offer value for money lower cost systems for buildings where a reduced performance is more than acceptable. However, their experience has shown that some customers are still prepared to accept lower cost alternatives even when the project demands that they should be trading up to take into account increased longevity and performance. A small increase in material costs can make a huge difference, but it could then be the choice of losing that project to a competitor if the building owner or specialist contractor is determined to go down the cheapest route. Yes, the building will be waterproof for 10 or more years but it could have been much longer with a better high performance product. Built up felt systems are a classic example of this. Choose a top of the range elastomeric, professionally installed and it can deliver up to 40 years or more of useful life. Start to come down the range and you begin to lose that performance Proteus Waterproofing say they will always recommend the best system for the job and like everyone else are very aware of budget constraints but often there is so little in price to consider, especially when looked at over the whole life of the building that it seems wrong to go for cheaper alternatives. You cannot really blame the manufacturers or contractors. These are the ground rules where the lowest possible price is still the system of choice. Will it ever change – sadly no – unless there is draconian new legislation and with Grenfell still fresh in everyone’s mind – that may yet happen. Visit: www.proteuswaterproofing.co.uk

Will it ever change – sadly no – unless there is draconian new legislation and with Grenfell still fresh in everyone’s mind – that may yet happen. Visit: www.proteuswaterproofing.co.uk

    Time is of the essence in business, particularly the roofing business, writes Mahroof Hussain, Area Technical Manager at Sika-Trocal. Delays, however minimal, incurred during commercial new-build or refurbishment projects can lead to unexpected costs to the client. When someone falls behind schedule in a multi-trade works programme, the knock-on effect can be disastrous. If a roof’s waterproofing is held-up, interior works are also likely to be delayed with the building not being weatherproof. This means the installation of floors, walls, electrics, plumbing and the like are also put on hold. The overall effect of this type of stalling could set a project back weeks and months, rather than hours or days.  Rapid development Product innovation and the streamlining of the building process itself is vital to helping contractors, developers, etc, fulfil the project expectations. Sika-Trocal’s Type S waterproof membrane presents a fine example of a system created specifically for the 21st century roofing market. Suitable for new and refurbishment projects, the Type S system uses dedicated Sika-Trocal laminated discs to fasten the membrane and the insulation to the substrate. Mechanical fixing has been proven to speed-up the roof waterproofing process by up to 30%. The improved application time is due to solvent-welding methods devised to fuse the overlapping membrane rolls; a practice pioneered by Sika in the UK. Employing this process, rather than the more traditional heat-welding method, also results in a neater, more attractive waterproof finish. Heat welding requires a temperature of more than 350°C in order to successfully fuse membrane layers. Although there is no naked flame involved, in inexperienced hands a membrane is at risk of discoloration using this method. Mechanically- fixed, solvent-welded membranes also require less equipment to install. This benefit, along with its time-saving attributes which reduce on-site working hours, means the Type S system helps cut pollution caused by machine-based emissions. Wind resistant  The Type S system comprises of a vapour control layer, insulation and membrane which is held in place by Sika-Trocal discs. These are spot-welded to the membrane. The fixings allow the whole system to be mechanically-fastened to a roof’s structural deck. The added strength this provides makes the Type S membrane an ideal waterproof solution for roofs located in exposed areas where high wind uplift is a common hazard. Speed of installation and reliable, long-term performance are the properties which attract contractors and renowned commercial brands to specify Sika-Trocal’s Type S. Supermarket stores nationwide have historically been fitted with the system. Its rapid delivery minimises disruption to businesses, hence its specification in September for a new supermarket site where its installation across a 600m2 roof area was completed in just  three days. The system’s speedy installation doesn’t compromise its quality, however. It is why Sika-Trocal’s Type S system is the rapid, long-term solution when it comes to waterproof roofing.

    The devil is in the detail when it comes to roofing, it only takes a minor oversight to cause a major issue writes Ian Weston, General Manager at Aperture. A roof’s weathertight protection requires more than a membrane and insulation. A commercial project is likely to include a host of plant facilities such as solar panels, rooflights, air conditioning units and fire escapes. Such details can lead to damp and ingress penetration, and the waterproofing system’s failure, if not sealed correctly. Therefore, the need for a proven solution is essential in ensuring plant penetrations and the roof itself remains watertight.    Ideal solution As with most, if not all roofing projects, selecting the appropriate waterproofing system is crucial in applications involving a plethora of plant penetrations, PV panels, air conditioning units, rooflights which require regular maintenance. A single-ply solution where an array of plant materials is present is not advised. When exposed to foot traffic and equipment used during maintenance visits, single-ply membrane is susceptible to damage. This in-turn is likely to lead to leaks and costly, long-term performance issues. Evolution Construction sites are a combustive mix of toil, tools and trades; therefore it’s not unusual for elements of a project to be left to the last minute. However, when this comes to waterproofing details all sorts of problems can arise. This is where a company such as Aperture comes into its own. Originally set up to deal with penetrations in composite roof panels Aperture has evolved over its 17-year history in the industry to combat any type of roof detail and penetration. Aperture liquid coatings are compatible with a wide range of existing substrates including, but not limited to, bituminous systems, asphalt, single-ply, concrete, timber and metal-profiled sheets. The Aperture system has permanent elasticity with a durable finish. It is hand applied by directly employed operatives, with minimal disruption and once complete, it is maintenance-free. Approved by Kingspan for use with its systems, the Aperture solution is backed by its own BBA certificate. Awkward details Due to the compatibility with most substrates, the Aperture solution is ideal for solving the sorts of problems encountered on new-build projects. These can vary from interfaces between two non-compatible waterproofing systems, awkward access details and most commonly, service riser penetrations. The application is totally cold-applied. Based in Manchester, Aperture carries out several hundred projects across the UK each year. Its operatives are first-aid trained and qualified to a minimum SSSTS standard. This provides the client and employer with additional peace of mind whilst waterproof installation teams are on site. Originally formed in 2000, Aperture was headed by Mick Philbin who retired in April 2018. To ensure the company continued along its successful path, Mick worked closely with new General Manager, Ian Weston, for the first four months of 2018 to ensure a smooth transition. Speaking of his new position, Ian said Aperture’s success is based on its ability to react to any type of situation in a short period of time. He said: “I’m sure our customers see us as the ‘go-to’ people when a difficult waterproofing detail arises. It’s my intention to not only continue this service, but to build upon it and improve our customer base, whether it’s a multi-million pound new-build or refurbishment, or a small building conversion, Aperture has a huge range of solutions to deal with the seemingly minor details.” Visit: https://aperturesp.co.uk

    As building owners become more environmentally aware, enquiries to convert existing flat roofsinto green roofs have never been higher. On face value this would seem an easy task but with modern building regulations demanding increased levels of insulation as well as practical challenges such as the heights of parapet walls and other upstand restrictions – the entire process can in reality be a lot more difficult writes Justin Pitman of Proteus Waterproofing. Many buildings, particularly those constructed in the 50s and 60s were never designed to take green roofs. Even assuming that the deck could handle the weight of an extensive sedum roof there are still several major obstacles to overcome, but none are insurmountable. In recent months Proteus has developed a new waterproofing system using its exclusive Cold Melt® membrane with an advanced hybrid insulation that enables a warm roof application to be easily installed on a refurbished deck. A green roof is laid over the top and a combination of the hybrid together with the added insulation properties of the additional soil and plantings, ensures that all current building regulations are met - and here comes the added bonus – the combined insulants are thinner than conventional boards which means that in most cases there is still at least 150 mm of upstand available to safely encapsulate the roof around the borders. Such green roofs are usually applied in urban or built up areas where there is a high risk of disruption or annoyance from odours when the membrane is installed. The advantage of Cold Melt® is that it is odour free and totally seamless making it ideal for a green roof. It is BBA accredited to last for the lifetime of the roof structureand best of all, the membrane itself incorporates recycled material making it one of the greenest on the market. What it does is to make available the opportunity for every building owner to actually consider a green roof application, particularly in the light of recent climate change warnings. Every green roof is of course different and will require its own calculations to ensure the right levels of insulation are used but the answer is no longer – NO – giving every building owner the chance to do their bit for the environment.

    The construction industry faces many challenges. One of these is around delivering projects on time and on budget writes Fiona Irvine LIoR, Technical Services Advisor, Sika UK. Refurbishment projects is one area where accurately predicting cost and time is notoriously difficult as all too often unforeseen factors come into play when a project starts, typically as a result of stripping away part of the building and finding something unexpected. Thermal imaging is one area where technology is helping to overcome this and is now a key part of Sika roof refurbishment offering. Infrared thermography (IRT) and thermal imaging technology detect radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 µm). This produces an image called a thermogram. Since infrared radiation is emitted by all objects with a temperature above absolute zero, thermography makes it possible to see an environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature. Therefore, thermography allows you to see variations in temperature. When viewed through a thermal imaging camera, warm objects stand out well against cooler backgrounds. Thermography has a long history, but its use has increased dramatically with the commercial and industrial applications of the past fifty years. Typical uses include firefighters who use thermography to see through smoke, to find people and to localise the base of a fire. Maintenance technicians use thermography to locate overheating joints and sections of power lines, which are a sign of impending failure. In the construction industry it has been traditionally used to identify heat leaks in faulty thermal insulation and to improve the efficiency of heating and air-conditioning units. Sika has been using thermal imaging technology since 2014. Investment in the technology was driven by the Sales Management Team as a way of adding value to clients. Sika has also invested in me as an individual to become a certified Level 1 thermographer, with training conducted by the world renowned Infrared Training Centre (ITC). As a global leader, working across a variety of market sectors from construction to automotive (see http://bit.ly/2o8Ca6Z) investing in technology and adding value across our supply chain is an essential part of what we do - everyday. We have predominantly used thermal imaging on refurbishment projects to track the extent of damage to the existing roof build up. It provides a much more comprehensive survey report and enables the creation of a more appropriate and suitable specification. It also helps to highlight, in advance, any issues that would have otherwise been unforeseen, helping to reduce risk and avoid any delays or additional costs. For example, we can locate saturated insulation within a roof build up. This can then be backed up with core samples to determine if a roof can be locally stripped to remove damaged insulation or whether a full strip is required. This means we can be more accurate when working with contractors, helping them to accurately price work and identify the most suitable approach, such as removal and replacement of localised roof areas. Thermal imaging provides a wealth of information the naked eye cannot see. It allows us to narrow down the locations where destructive core samples are required. It also provides a visual representation of how the roof is performing thermally. Sika is always striving to be ahead of the competition and utilsiing thermal image is one element of this. However we don’t intend to sit on our laurels. There are several ways to survey a roof and we will continue to look at how technology can aid this. However it shouldn’t stop there. Sika has successfully proven that thermal imaging can add value to roof refurbishment projects and we must now consider what other construction applications it has beyond a roof. For example, how can it be used on flooring, or structural strengthening or concrete repair applications? We will continue to invest in technology that helps us reduce clients risk and deliver projects more effectively. It’s what’s makes Sika that little bit different – it’s what we do every day.

    With ever-greater pressure being applied to the private and commercial sector purse strings, the need for building projects to be completed on time without minimum fuss becomes more significant writes James Wilkinson. There is little margin for error for contractors working to tighter-than-before deadlines, and that includes ensuring the correct specification of a waterproof, durable flat roof system. But what are the challenges facing architects and contractors when selecting suitable flat roof insulation? And why do such roofs sometimes fail?  As a building’s first line of defence and prominent thermal feature, a roof must maintain long-term, maximum performance. Therefore, every aspect of its installation should be considered to ensure it remains watertight, problem-free and energy-efficient during its lifetime. The specification of bespoke, single-layer tapered systems can help alleviate risk when it comes to flat roofing. This outcome is easiest and best achieved in conjunction with Gradient, a specialist roof insulation manufacturer which works closely with customers on the design and manufacture of tapered solutions for a wide range of roofing applications. Fitting solution Placing the insulation process - from start to finish - into the hands of highly-experienced and skilled professionals not only maximises control standards in roof design, manufacture, performance and sustainability, it results in a better-conceived flat roof which is improved in value, performance and complies with all relevant legislative standards. Gradient is able to supply specialist technical support to provide customers with flat roof solutions - whatever a roofing project’s stage. However, it’s fair to say most problems occur when clients fail to engage such companies at the very start of the roof specification process which minimises the risk of future problems. The close proximity of door thresholds to roof decks, for example can result in underperforming U-values and is a common issue. It’s an oversight which can lead to water-ponding and possible insect infestation, but can easily be avoided with early involvement from Gradient. In such cases, a tapered roof insulation scheme can be applied, but the thermal performance will not be as good as it ought to be due to the aforementioned fault at the design stage. Encouraging developers to consider roof insulation performance long before they start construction is key to trouble-free roofing. When a building’s shell and certain fixtures and fittings are in position before roofing issues have been fully-addressed, it can often lead to height limitations being imposed on the insulation installed. Thus, flat guttering, the same thickness as the insulation is seen as a solution. Whilst this might be seen as a perfectly acceptable system for installers, developers would quite reasonably prefer a completely run-dry roof on which water is pushed to all available outlets. Condensing the risk Constraints on insulation height will sometimes rule-out the use of a fully-tapered roofing scheme, therefore a compromise on a particular roofing detail may have to be reached. It could lead to a roof design which doesn’t necessarily reflect best practice, but is nonetheless the best scheme with all factors considered. Compromise can take the form of a lower U-value, or the installation of a hybrid roof scheme in which insulation is applied below the deck.

  • With ever-greater pressure being applied to the private and commercial sector purse strings, the need for building projects to be completed on time without minimum fuss becomes more significant writes James Wilkinson. There is little margin for error for contractors working to tighter-than-before deadlines, and that includes ensuring the correct specification of a waterproof, durable flat roof system. But what are the challenges facing architects and contractors when selecting suitable flat roof insulation? And why do such roofs sometimes fail?  As a building’s first line of defence and prominent thermal feature, a roof must maintain long-term, maximum performance. Therefore, every aspect of its installation should be considered to ensure it remains watertight, problem-free and energy-efficient during its lifetime. The specification of bespoke, single-layer tapered systems can help alleviate risk when it comes to flat roofing. This outcome is easiest and best achieved in conjunction with Gradient, a specialist roof insulation manufacturer which works closely with customers on the design and manufacture of tapered solutions for a wide range of roofing applications. Fitting solution Placing the insulation process - from start to finish - into the hands of highly-experienced and skilled professionals not only maximises control standards in roof design, manufacture, performance and sustainability, it results in a better-conceived flat roof which is improved in value, performance and complies with all relevant legislative standards. Gradient is able to supply specialist technical support to provide customers with flat roof solutions - whatever a roofing project’s stage. However, it’s fair to say most problems occur when clients fail to engage such companies at the very start of the roof specification process which minimises the risk of future problems. The close proximity of door thresholds to roof decks, for example can result in underperforming U-values and is a common issue. It’s an oversight which can lead to water-ponding and possible insect infestation, but can easily be avoided with early involvement from Gradient. In such cases, a tapered roof insulation scheme can be applied, but the thermal performance will not be as good as it ought to be due to the aforementioned fault at the design stage. Encouraging developers to consider roof insulation performance long before they start construction is key to trouble-free roofing. When a building’s shell and certain fixtures and fittings are in position before roofing issues have been fully-addressed, it can often lead to height limitations being imposed on the insulation installed. Thus, flat guttering, the same thickness as the insulation is seen as a solution. Whilst this might be seen as a perfectly acceptable system for installers, developers would quite reasonably prefer a completely run-dry roof on which water is pushed to all available outlets. Condensing the risk Constraints on insulation height will sometimes rule-out the use of a fully-tapered roofing scheme, therefore a compromise on a particular roofing detail may have to be reached. It could lead to a roof design which doesn’t necessarily reflect best practice, but is nonetheless the best scheme with all factors considered. Compromise can take the form of a lower U-value, or the installation of a hybrid roof scheme in which insulation is applied below the deck. The latter solution is not ideal, as condensation is often a by-product. However, roofing firms such as Gradient are able to carry out calculations for a hybrid roof that will eliminate the risk of condensation. Whichever roofing insulation specified, its performance is only as good as the installer. Selecting a proven contractor to carry out installation work is vital - a task becoming more challenging by the day with Britain facing its biggest skills shortage for a generation, particularly in the roofing industry. If a contractor omits to fully-tackle air gaps, for example, in a perfectly-designed roof, the potential for condensation remains.

    The roofing industry has undergone huge changes over the past decade, writes Shay Casey, Senior Sales Manager at Sika-Trocal. Technology has inspired its growth, with specification and design innovation keeping step with dynamic project visions. BIM modelling, digital presentations and even refurbishment surveys can be carried out using a drone or virtual programmes. Technical advancement has led to a marketplace brimming with new products and systems. Greater choice has led to increased competition, with contractors offering complete roofing and cladding packages – a major change in the specification and application process. The introduction of a wide range of new membranes has seen contractors adapt specifications to ensure the most cost-effective installation; an option not available to architects or clients who no longer have the power to uphold the original specification. This can result in them having to accept products of inferior quality, which isn’t ideal. Today’s roofing contractors need to be more financially aware than ever before, due to the rise of extended payment terms and retentions which have proven a huge burden to buyers and suppliers. Firms throughout the construction have also had to adapt to new ways of self-marketing. In previous years, a simple advert in the local newspaper or Yellow Pages was thought of as a most effective promotional tool. The internet, and more particularly, social media has revolutionised the way we communicate. Rather than rely on repeat business or word of mouth recommendations, a hefty LinkedIn or Twitter presence can spread positive word of a contractor’s service offering in a matter of seconds. Environmental concerns have also led to a welter of roofing industry changes, with the introduction of green and cool roofs, solar panels and further developments in roof lighting. The Green Guide has led to vast improvements in recycling, manufacturing footprint and roofing performance in terms of thermal values and sustainability. The knock-on effect of the drive for a ‘cleaner’ project delivery means sales teams not only have to be fluent in their products’ properties, an understanding of their compatibility with new technologies and environmental standards is also required.  Virtual reality has also revolutionised our personal interactivity. From simulated flight control and fairground rides, to historical battlefields and exotic holiday destinations, a world of artificial exploration is available for those with a taste for risk-averse exhilaration. It’s likely virtual reality will also prove useful to the roofing sector in the coming years, allowing stakeholders involved in a project to visualise how it will look when completed. This will help minimise misunderstandings between parties which can lead to frustrating, costly delays for the client. New technologies should – in theory at least – make for more rapid construction,with contractors able to tailor projects to a client’s specific needs. It might be that technology will replace people skills in certain areas of construction. In which case, with digital wizardry perhaps taking care of a project’s more technical aspects, it might mean the industry’s future workforce will merely require a broad range of abilities and knowledge to remain employable. Since I joined Sika-Trocal in 2004 my licensed contractors have installed more than 2million linear metres of Trocal membrane, which equates to more than 1300 miles of material – enough to cover the length of the GB and back again. During those 14 years my customer base has grown and I have thrived on the competition the market has imposed. Each day is a challenge to gain specification for Trocal products and our comprehensive range of services and accessories which include insulation, fixings and rooflights. Over the coming decade the roofing industry will doubtless face many challenges, and as practices and systems change, members will be required to adjust accordingly. With the support of trade associations such as SPRA and NFRC, the future should hold no fear for those involved in the roofing sector. Here’s to my next 2 million linear metres.

    Contrary to popular belief it is almost impossible to start a fire on a green roof according to most experts. Fears that plants and other foliage would present a fire risk, particularly during the hot summer months have proved to be unfounded. Research has shown that the risk of fire is 15-20 times higher on traditional flat roofs with fully adhered bituminous waterproof membranes compared to extensive green roofs with grasses, perennials and Sedums In spite of this there has still been talk in recent years that we could be creating a “fire of London” situation where flames would spread from one green roof to another, fanned by the higher winds experienced on most tall buildings. So far, so alarmist but there is no doubt that fire fighters are concerned that in the event of a building fire, a green roof would trap heat and with the increased weight above, such a structure would provide an additional hazard once internal supports had been compromised. With the recent tragic events of Grenfell, all sectors of the construction industry are looking more closely at the regulations and developing new products and systems to provide maximum fire protection. One of the most likely potential problems for a green roof would be the spread of fire from an adjacent building via a party wall. One company, Proteus Waterproofing, based in Essex, have already identified such a scenario by producing a roof waterproof system that includes all the best U values from insulation such as PIR, combined with the fire resistant qualities of mineral wool. The system can be used with a whole range of different membranes. Such a package also offers a higher level of protection to buildings with green roofs by offering greater levels of fire resistance. It does mean of course that roofing now has to be designed in an entirely different ways to ensure that U vales are maintained and fire safety remains uncompromised. The European Standard is B Roof T4 which all roofs, particularly where it relates to party walls or compartmentation, must be achieved and this is the challenge for all new green roofs and similar design situations’ The first “true” extensive green roofs were built in Germany around 35 years ago and today it is estimated that there are at least five billion square feet of extensive green roofs built across Europe. This equals at least 350 square miles of green roofs with estimates that we are adding a further 20 new square miles every year. As green roofs have become more successful the critical comments about safety issues have also increased. However there is no record of any fire directly related to a green roof. But as we have seen, the weight of a green roof is a major potential hazard in a building fire but it now seems that we have a potential solution with companies such as Proteus developing systems that protect and contain the spread of fire. Sounds good to me…. By John Ridgeway Visit: http://proteuswaterproofing.co.uk/

    Earlier this year, data released by the Office for National Statistics revealed the risk of suicide among low-skilled male laborers, particularly those working in construction, was three times higher than the national average. Mental illness has long been considered something of a taboo subject within the building industry, leading to companies such as BriggsAmasco, the UK’s leading national commercial roofing company investing in training schemes designed to educate employees and help them recognise the symptoms of psychological stress. Dave Maginnis, Managing Director at BriggsAmasco, talks about the education programme and his company’s aim to highlight  issues surrounding ‘the invisible illness’. Construction is a tough environment to inhabit. The physical demands are heavy and the pace at which workers have to toil is unrelenting. There are also mental pressures. Deadlines need to be met on a daily basis to satisfy a seemingly never-ending chain of command that begins with the client, but can include a host of contractors and various trades which are dependent on a person a lot further down the line getting their bit right for a project to proceed at sufficient speed. Therefore, it’s fair to say the building industry, particularly the roofing sector, is not for the faint-hearted. If we concur with the stereotypical view, then construction workers are as tough as the materials in their possession; they’re insensitive to the perils they face in their line of duty, and they’re mostly easy-going types whose hard-earned brawn has insulated them against the fears and anxieties felt by those engaged in less-rigorous employment. The reality is somewhat different, however. This is borne out by figures that reveal one-in-six construction-based workers are suffering from a form of mental illness. The fact that suicide kills more people in the building sector than falls is even more daunting. Thankfully, it appears the industry itself is becoming aware of the health issue in its midst. Initiatives such as Mates in Mind, a recently-launched charitable programme designed to improve and promote positive mental health in construction, has the backing of the British Safety Council, the Health in Construction Leadership Group, and the Samaritans. However, when it’s considered a 2006 CIOB report, showed 70% of workers suffered from stress-related mental conditions as a direct result of working in the industry, its clear employees within the sector should be taking a firmer lead on ways to address the issue. Warning signs In June, BriggsAmasco staged a workshop for employees to help them recognise signs of mental health problems and encourage individuals to seek the right help. It was held as part of our annual Health and Safety forum on behalf of contract-related staff and subcontractors.The Mental Health First Aid coursewas delivered by a qualified, external trainer to ensure an effective and efficient approach was taken in relation to the subject. People often respond better to an outsider with a proper understanding of the topic they are delivering, and our aim was to ensure that our employees fully-absorbed the message being conveyed.   Staff interaction was encouraged throughout the course by sharing knowledge and personal experiences of the illness in an open-floor environment. Details were also shared on various mental health issues, and the warning signs to look out for, such as stress, anxiety and depression, that could indicate someone has a condition. The feedback from colleagues who attended the course was extremely positive. Most told us they found it incredibly insightful and gave them a new approach in their thought process regarding mental health issues. This was precisely the result we were hoping for. BriggsAmasco has covered more than 1,000 hours in health and safety training and awareness through internal and external courses. We also hold annual health surveillance assessments for our 200-plus safety-critical employees in which a detailed wellbeing assessment is carried out by a medical professional. This robust approach to the welfare of staff led to the company achieving ISO, 9001, 14001 and 18001 – one of a few UK organisations to meet all three standards. Adapting to change Health and Safety is paramount at BriggsAmasco. However, with so much focus being applied to the day-to-day safety aspect; the health issue is sometimes left in the background. Therefore, we felt it extremely important to raise awareness on the subject of mental health and reassure our employees that the support is there if and when required. Mental health issues reportedly account for people taking nearly 70 million days off sick per year – the most of any health condition – costing the UK economy between £70 billion and £100 billion a year. Proof, therefore, the ramifications of this debilitating condition can travel far beyond the distress it causes an individual. The construction industry has been viewed by some as resistant to adapting to changes in working practices and behaviours, but it’s been swift to act in relation to a hitherto unspoken issue: the psychological wellbeing of its employers. At BriggsAmasco, we are aiming to overturn the negative view of mental illness and open-up discussion about its causes, symptoms and diagnoses. In our opinion, the construction industry should approach the welfare of its members with the same precision applied to a high-profile building or engineering project, which means paying as much attention to the interior, as well as the exterior details.

    Small details pay big dividends in roof specification. As a building’s first line of defence and prominent thermal feature, a roof must maintain long-term, maximum performance. Therefore, every aspect of its installation and insulation should be considered to ensure t remains watertight, problem-free and energy-efficient during its lifetime. Andrew Rowley, Senior Designer at Gradient, the UK’s leading supplier of tapered roof insulation, highlights a few seemingly minor roofing issues, which if not addressed correctly, could result in major problems following installation. By failing to prepare, we prepare for failure - an oft-repeated phrase which applies very favourably to successful roof installation and its thermal performance. In the UK, homes are responsible for 27% of carbon emissions, a statistic that requires serious attention, especially as our government committed to reducing the country’s CO2 emissions by 80% by 2050 as part of the Climate Change Act. To improve the thermal-efficiency of buildings old and new, perhaps we’d be advised to adhere to another well-known phrase - prevention is better than cure. Tapered and tailored to suit  The specification of bespoke, single-layer tapered roofing solutions can help alleviate risk when it comes to insulation. This outcome is easiest and best achieved in conjunction with companies such as Gradient which works closely with customers on the design and manufacture of a suitable system for a wide range of roofing applications. Placing the insulation process - from start to finish - into the hands of highly-experienced and skilled professionals not only maximises control standards in roof design, manufacture, performance and sustainability, it results in a better-conceived flat roof which is improved in value, performance and complies with all relevant legislative standards. Gradient is able to supply specialist technical support to provide customers with flat roof solutions - whatever a roofing project’s stage. However, it’s fair to say most problems occur when clients neglect to engage such company’s at the very start of the roof specification process which minimises the risk of future problems. The close proximity of door thresholds to roof decks resulting in underperforming U-values is a common issue. It’s an oversight which can lead to water-ponding and possible insect infestation, but can easily be avoided with early involvement from the roof insulation manufacturer. In such cases, a tapered roof insulation scheme can be applied, but the thermal performance will not be as good as it ought to be due to the aforementioned fault at the design stage. Encouraging developers to consider roof insulation sizes long before they start casting concrete is key to trouble-free roofing. When a building’s shell and certain fixtures and fittings are in position before roofing issues have been fully-addressed, it can often lead to height limitations being imposed on the insulation installed. Thus, flat guttering, the same thickness as the insulation is seen as a solution. Whilst this might be seen as a perfectly acceptable system for installers, developers would quite reasonably prefer a completely run-dry roof on which water is pushed to all available outlets. Mind the gaps Constraints on insulation height will sometimes rule-out the use of a fully-tapered roofing scheme, therefore a compromise on a particular roofing detail may have to be reached. It could lead to a roof design which doesn’t necessarily reflect best practice, but is nonetheless the best scheme with all factors considered. Compromise can take the form of a lower U-value, or the installation of a hybrid roof scheme in which insulation is applied below the deck. The latter solution is not ideal, as condensation is often a by-product. However, roofing firms such as Gradient are able to carry out calculations for a hybrid roof that will eliminate the risk of condensation. Whichever roofing insulation specified, its performance is only as good as the installer. Selecting a proven contractor to carry out installation work is vital - a task becoming more challenging by the day with Britain facing its biggest skills shortage for a generation, particularly in the roofing industry. If a contractor omits to fully-tackle air gaps, for example, in a perfectly-designed roof, the potential for condensation remains. Strip to reveal For developer, contractor and customer, time is money in the construction industry. With budgets being tightened across the sector as uncertainty over Britain’s post-Brexit future remains; so ever-tighter deadlines must be met. However, quality must not be lost in the rush to reach the finish line. For refurbishment projects in which an existing roof is overlaid, Gradient is able to design a tapered scheme, with surveys made all the easier due to the visibility of the building’s falls. It’s part of the company’s service to carry out the same assessment when a roof is stripped to its deck. Time restrictions will often lead to contractors refusing the offer of a second visit, even though the stripped roof could reveal a deck to be damaged or uneven and in need of a rethink as to how the insulation should be applied to improve its long-term performance. Again, the answer is good preparation. Building extra time into a roof’s installation before installers arrive on site will help avoid unseen issues which may crop-up as the process continues. Quality roof insulation, which protects against the ravages of the elements and time, as part of a long-term, waterproof system, doesn’t arrive by accident - it’s most definitely the result of excellent design and installation.

    Roofing can be an incredibly precarious profession, writes Dean O’Grady, Product Manager at Sika. One in five deaths in construction work involves roof projects, whether in the course of carrying out specialist work or simple maintenance. A roof’s height and potential fragility creates an immediate risk factor, which is increased manifold by the use of naked flame processes applied during installation or maintenance. To help reduce the perils associated with roof fires through naked flame applications used to dry-out or install torch-on membranes, the NFRC has launched a Safe2Torch campaign. Roof contractors across the UK are being asked to support the initiative which offers a host of best practice guidelines designed to minimise the threat of roof fire and reduce the risk to life and property. Companies which pledge their support to the campaign will indicate they have read and understood the guidance and are committed to promoting and implementing the campaign throughout their organisation. This will provide clients with the assurance that their contractor/manufacturer has planned their roof works in accordance with safety advice outlined in the Safe2Torch campaign. Safety points Included within the Safe2Torch campaign is a section focusing on pre-hot works checks that should be carried out to eliminate potential hazards associated with the use of gas torches. These include: Ensuring any combustible materials such as dry leaves, flammable liquids, wood, paper, etc, are removed from the working area Assessing the roofing substrate, as under no circumstances should a torch be applied direct to a timber-based deck or upstand Avoiding naked flame or high heat contact with foam or fibreboard combustible fillers found in expansion joints Selecting a torch-free product for abutments with open cavities or open perpends Avoiding using naked flames near fixed timber, plastic fascia or soffits Although Sika specialises in roofing products that eliminate the use of a naked flame applications, we would urge companies throughout the industry to support the Safe2Torch campaign, as we feel the health and safety of employees within our sector should be the number one priority of manufacturers and contractors alike. Ultimately, the way to mitigate issues with roofing naked flame works is to select a safer installation system. This will not only improve safety, it can help reduce installation time and on-site costs. Sika supplies a wide range of products which are rapid and simple to install for a wide range of flat roof applications. Cold options For example, the Sika-Trocal S-Vap 5000E SA is a new multi-layer, self-adhesive vapour control layer, which offers superb bonding strength for air-tight roof construction. Consisting of polymer-modified bitumen with a glass-fibre mat reinforcement and an aluminium foil as top layer, The self-adhesive feature eliminates the use of naked-flame installation, making for safe, simple and quick installation. It can also provide a temporary waterproof layer for up to four weeks without the aid of additional weight, ballast or mechanical fastening.  Capable of withstanding heavy foot traffic without tearing, S-Vap 5000E SA is perfect for use on profiled metal decks. Ideal for a range of substrates, it can be used in conjunction with Sika C-250 Spray insulation adhesive in an adhered roof build-up without the need for fasteners to secure thermal insulation boards. Sika C-250 Spray is applied via a pressurised canister that covers an approximate 140m², in minutes, a benefit that has helped speed-up the installation of Sika-Trocal single-ply roofing systems by up to 50%. Primer 610, also from Sika-Trocal, has been specifically developed alongside S-Vap 5000E SA. also spray-applied via a pressurised canister that covers an approximate 180m2  to 200m2 roofing area, Primer 610 dries in minutes; a benefit that also helps speed-up the installation of Sika-Trocal single-ply roofing systems. Like the S-Vap 5000E SA, versatility is one of the Primer 610 system’s many strengths, enabling its use on many existing substrates. The NFRC is to be applauded for its Safe2Torch initiative; any campaign which seeks to make the industry safer deserves our utmost attention and respect. Bituminous systems have been around for centuries, and because ‘torch-on’ is tried-and-tested with contractors reluctant to change their application method, it’s likely hot-working practices will continue for years to come. There is an alternative, however, and with on-site safety quite rightly a major concern within the industry, perhaps it’s time roofing companies warmed to the idea of systems without hot works.

    The move towards mortar-free, dry fix roof and drainage solutions has made it quicker, easier and safer to install throughout the build process. Offering a wealth of benefits to the installer and homeowner, Hayley Lowry, Marketing Manager of Ariel Plastics outlines the dry-fix options for new-build projects and how these systems are the simple, cost-effective, low maintenance route to a weathertight roof, whatever the elements have in store. Dry fix roofing is the term used to describe the mechanical fixing of roofing materials. Traditional mortar bedding is still the most widely-used fixing method in England and Wales, in contrast to Scotland, where 80% of roofing is already mechanically-fixed. However, the increased incidence of storms during recent years has clearly highlighted the unreliability of mortar. The switch to dry fix roofing in Britain and Ireland is well established but looks set to gather even greater momentum. Considering all the advantages, it is not difficult to see why. The roof is the most exposed part of any building. Using mortar to secure vulnerable areas of the roof, such as the verge, will inevitably lead to future maintenance. Differential movement causes mortar to crack and no reliance should be placed on its tensile or shear strength. The action of frost and rain will exploit the development of hairline cracks. In contrast, because dry fix roofing is mechanically-fixed it offers improved safety, security and increased resistance to wind uplift and water penetration. Dry fixing is a year-round solution; it can be carried out in damp and freezing conditions. A fast and simple process, it’s a method that eliminates the need for mix-and-apply mortar and its incurring mess. Special skills and tools are not required to dry fix, making it highly cost-effective. It also complies with BS 5534, a new code of practice that details design standards, performance and installation of pitched roofs and vertical cladding using slates, tiles and wooden shingles. Regulation change BS 5534 came into force in February 2015 and outlined a number of changes including the use of mortar, which can no longer be used in isolation to fix ridges and hips. These should now also be mechanically-fixed. Fixing requirements for roof tiles have been increased in the latest code of practice which also requires all single-lapped tiles on a roof to be mechanically-fixed. It also states perimeter tiles should now have a minimum of two fixings. In addition, testing bodies now have to assess the measurement of the wind uplift resistance of underlays. The Construction (Design and Management) Regulations place a duty of care on designers to select building components that minimise health and safety risks, not only during construction, but during future maintenance. The use of dry fix roofing eliminates the need to repair failed mortar bedding, therefore avoiding future maintenance work and improving safety on site. In terms of dry fix options, mortar-freeproducts which provide a unique jointing system and can be used with half-round and angled ridges are ideal for this practice. This is not only the quickest method of installing ridge tiles to a roof; it produces a neat ridge line of traditional appearance whilst also providing high-level ventilation. Product options For dry verge, the ideal products are ones which enable verge tile fixing without the need for mortar whilst protecting verge tiles from wind uplift, pest infestation and weather degradation. Most systems are universal and come in a range of colours to blend with most tiles, slates and bargeboards. With the UK experiencing more frequent extreme weather conditions, greater responsibility has been placed on the roofing underlay to cope with increasing wind forces. The potential effect of an underlay subjected to excessive wind loading is for it to balloon upwards potentially causing the tiles or slates to dislodge. This issue has been addressed in the latest revision to BS5534: 2014 Code of Practice for Slating and Tiling. Effective from March 2015, the guidance outlines the minimum requirements for taping the side laps of roofing underlays dependent on the exposure of the roof to wind uplift, batten gauge and the underlay selected. In addition to the prevention of wind uplift, the taping of side laps of roofing underlays helps improve the thermal performance of a building by reducing air filtration and convective heat loss. Dry fix valleys are another product option. Fully-weatherproof options manufactured from GRP are now available offering a cost-effective alternative to lead.  Dry fixing of valley troughs is quicker, less dependent on site skills and guarantees a neater finish than mortar bedding. Slate, tile and ridge vents are available to install mechanically on the roof without the need for mortar. Similarly, a wide range of eaves ventilation products are available to mechanically fix: eaves vent kits, rafter and fascia trays, over fascia vents and soffit vents. With availability of so many proven products, it’s no wonder the construction industry is rapidly turning to dry fix products as the quick, easy-to-apply, cost-effective solution for weathertight roofing.
