This complicated asbestos roof structure was heavily soiled and leaking in numerous places. Asbestoseal was specified because it is the only BBA Approved asbestos roof coating on the market. The roof was cleaned using 150°c steam, which kills all moss and lichen spores on contact, leaving a perfectly clean substrate for coating. The success of any coating comes from its preparation and Liquasil teaches all of it approved installers various cleaning methods. The roof was coated and is now leak free with a much extended life expectancy.

This 4,000 square metre roof in Lichfield, completed by Projects UK Ltd, was in need of refurbishment and Liquasil's BBA Approved Metalseal 20 was specified for its 20 year guarantee against manufacturing defects. The roof was cleaned and the cut-edges were treated with our unique SWT corrosion primer before a single coat of Metalseal 20 was spray-applied to the roof to provide a protective and decorative finish leaving the roof sheets looking like new.To get in touch, call our team of Building Surveyors on 0121 709 5352.

The multi-million pound refurbishment project saw the iconic building and its landscaped gardens restored to their former glory. Axter’s cold applied liquid waterproofing systems delivered a high quality solution to this challenging refurbishment.Systems in useStarcoat® QCStarcoat® PMMAKensington Roof Gardens is one of London’s best known venues, once famous for its flamingos and celebrity guests. The Grade II listed gardens were designed by landscape architect Ralph Hancock and date back to the 1930s. The venue features one of Central London’s most famous intensive living roofs and also includes an indoor restaurant, entertainment space and elevated terracing.ChallengesThe refurbishment of Kensington Roof Gardens was technically demanding. This was due to the complexity of the waterproofing details and space restricted installation locations as well as the specific waterproofing requirements.The refurbishment of the pond and waterways required a liquid waterproofing system that is proven to be safe for aquatic life, is UV stable and meets the aesthetic requirements. In addition, the waterproofing for the elevated terraces and walkways needed to be robust, rapid curing and appropriate for high traffic areas with a high quality, anti-slip finish.SolutionsAxter’s Technical Sales Team was able to provide BBA approved liquid waterproofing specifications for both areas. Axter ensured the highest quality waterproofing installation in all areas.Starcoat QC flame free single component PU resin waterproofing was used for the pond and waterways. The system cures fast in just 4-8 hours depending on the conditions and creates a tough, seamless, elastomeric membrane. This makes it ideal for complex refurbishment projects, such as Kensington Roof Gardens, where effective bridging of cracks and resistance to structural and thermal movement is essential. The robust, solvent free membrane also simplified the waterproofing of the site’s complex details and is resistant to chemicals and root penetration.The Starcoat PMMA (polymethyl methacrylate) two component waterproofing, used on the walkways and terraces, is zero fall accredited, hard wearing and can withstand significant loading and mechanical stresses. Available in a choice of colours, traffic and anti-slip finishes, it also provides an excellent solution for complex detailing and challenging application areas.AcknowledgmentsThe refurbishment of the iconic Kensington Roof Gardens demonstrates the versatility of our Starcoat PU and PMMA liquid waterproofing systems. Working closely with our partners, we were able to provide a high-quality technical solution that benefits from a 25-year system guarantee.Phil Wilcox Moore, Managing Director at Axter

The original factory finish to the metal roof of this property was failing, with the coating delaminating badly due to UV damage. The gutterless eaves construction meant that both the roofs and cladding had to be coated. Metalseal was specified because it is available in any RAL colour., In this case, Juniper Green was required. The original finish was removed with 4000psi pressure washers , before corrosion was treated with Liquasil's corrosion primer before Metalseal 20 was applied.

Byker WallBauder Total Roof System (BTRS)SynopsisAs part of the £26 million refurbishment of this Grade II listed residential estate, which features a continuous block of over 600 properties, work was performed to not only repair the existing roof but to bring Byker Wall to the forefront of modernday roofing technology with the installation of a state-of-the-art photovoltaic system.Bauder Building BoardProject:Byker WallLocation:Newcastle upon TyneRoof Area:4,500m²Specifier:Your Homes NewcastleMain Contractor:KeepmoatApproved Contractor:Hodgson SayersProducts appliedBauder Total Roof SystemAn integrated bituminous system with a life expectancy in excess of 40 years as stated in BBA cert,BauderSOLARPhotovoltaic system was installed with 132 PV modules being fitted.The resultBefore replacing the existing waterproofing the team needed to convert the pitched metal roof back to its original flat roof status by removing the profiled metal sheets and timber framework. Subsequently, Hodgson Sayers then installed 4,500m² of Bauder’s top quality reinforced bitumen system, which included a highly efficient 120 mm PIR insulation. Four of the ten housing blocks were fitted with 132 PV Modules, enabling Byker Wall to generate at least 39.6 Megawatt Hours of solar power each year.

Cambridge University, Department of Civil EngineeringBauderBLUE STORMcell with BauderSOLAR G LightSynopsisThis new build project in the centre of Cambridge combines a Sustainable urban Drainage Solution (SuDS) with vegetation and renewable energy in a warm roof construction.The client for the Department of Civil Engineering at Cambridge University, R H Partnership, identified sustainability as being a key driver in the design of the roof, but also sought a single source supplier that could provide a guarantee for both workmanship and products. Bauder’s systems range encompasses products to meet all the sustainability objectives, and with our network of approved contractors carrying out the installation, we could offer the comprehensive guarantee that was required.Bauder Building BoardProject:Cambridge University Department of Engineering​Location:CambridgeRoof Area:1610m²Client:University of CambridgeSpecifier:RH Partnership ArchitectsMain Contractor:SDC LimitedApproved Contractor:Voland LimitedThe specificationTo meet the sustainability criteria set out by the client, the Bauder technical team designed a roof system combining an extensive blue roof, a green roof and a solar PV array. The first and most fundamental element of the roof system though is the waterproofing. Bauder Total Green Roof System (BTGRS) was selected as it provides robust and durable waterproofing with a life span in excess of 35 years, as validated by BBA Certificate 10/4744. The Plant E cap sheet has also been tested by the FLL to ensure long term root-resistance, making it ideal for use in conjunction with the BauderSOLAR G LIGHT system. The BauderSOLAR G LIGHT system is a unique way to combine rooftop vegetation with renewable solar energy. The PV panel mounting boards are held in position using the growing medium as ballast, meaning the waterproofing is not penetrated and therefore compromised. The mounting boards incorporate a water retention feature which allows a small amount of excess rainwater to be stored for short periods of time for the various plant species to feed from. The BauderSOLAR G LIGHT system’s unique mounting system lifts the panels above the vegetation allowing the plant life to grow freely and therefore qualify a greater area of the roof as biodiverse.In addition to the BauderSOLAR G LIGHT system, a blue roof was added to the build-up. Blue roofs are sustainable drainage solutions designed to manage stormwater on a flat roof to reduce water runoff rates and ease flash flooding and standing water in built up areas. The BauderBLUE Roof System attenuates water from a flat roof over a 24-hour period via a restrictive flow outlet. Calculations are carried out to determine the rate at which the water should egress the rooftop. This is determined by the local planning authority and is often set as low as 5-8 litres per second per hectare. With these calculations, Bauder can design each flow restrictorto meet the necessary runoff rate. For the Department of Civil Engineering, the main roof area of 1455.5m² required two flow restrictors, each with flow control holes to ensure the specified discharge rate of 0.77 litres per second was achieved. The maximum depth of water the roof is designed for is the H-max. When the water level reaches H-max, it will drain via the emergency overflow pipe. These overflow pipes are set at the same height as the H-max level. On this project the H-max was calculated to be 99mm. Although an unlikely scenario, this provision for a ‘once-in-a-hundred-years’ storm event will ensure that the structural integrity of the building is always preserved.Project challengesThe roof deck was constructed using a pretensioned concrete plank roof structure. Due to the large span of these planks, the dead load weight to the roof would be restricted. This being a blue roof with green landscaping and PV (a reasonably heavy build up), presented the issue of balancing the need of the roof design and the weight restriction of the supporting structure. To add to this challenging scenario, the pretensioned deck did not provide a completely flat finish. When installing a blue roof, a flat deck with no positive or negative falls is essential, as detailed in the 2018 update of BS 6229 – Flat roofs with continuously supported flexible waterproof coverings. To overcome this onsite challenge,the final deflection of the fully loaded roof was calculated and the concrete deck was screeded to give a flat finish.The resultBauder believes this project to be one of the first of its type in the UK to bring together so many rooftop systems in one space. Project management and clear communication was paramount in order to ensure a smooth installation. The Bauder project team consisted of green roof and solar PV product managers, area technical manager, technical design team, site technicians and approved installers for the waterproofing.With all the different elements being installed, green roof and solar PV product managers worked with our technical team to design the best possible PV array configuration for optimum energy generation whilst also qualifying for the maximum biodiverse area.Bauder site technicians worked closely with Bauder approved contractors, Voland Asphalte Ltd, to ensure works were kept to schedule and that a high quality of workmanship was maintained throughout.To ensure the landscaping is maintained, irrigation was installed by Access Irrigation Ltd. The system, Permadrip Pro, is a drip line irrigation system with anti-syphon design to resist clogging and pressure regulation. Due to the specialist nature of the irrigation system, Access Irrigation Ltd provided a bespoke design service.The result of this network of expertise was a multi-faceted support service for the client, specifier, main contractor and roofing and PV installers. System installedBauder Total Green Roof System (BTGRS)1 BauderPLANT E 42Green, 5mm torch-on root-resistant capping sheet.2 BauderTEC KSA DUOA self-adhesive, elastomeric, bitumen underlayer.

Once installed on the concrete pretensioned plank deck, it can act as a temporary waterproofing layer, allowing internal works to be carried out immediately which was a huge advantage on this new build project.BauderSOLAR G LIGHTThis BauderSOLAR G LIGHT system was a key factor in the specification of the project to meet the sustainability criteria specified by the client. 40 PV units were installed on the main roof area on the Departmentof Engineering. The forecasted energy generated for this arrayin its first year is 9.91MWh with a CO2 saving of 5.242 tonnes/a. BauderBLUE SR-B flow restrictorThe BauderBLUE SR-B flow restrictor is designed to be used in conjunction with a standard Bauder bitumen blue roof vertical outlet DN70. The flow restrictor is comprised of four parts; baseplate, overflow pipe, baseplate inner and baseplate outer seal. The polyamide baseplate fits within the 70mm vertical outlet, with the EPDM outer seal creating a watertight fit. The HDPE Overflow slots into the central hole of the baseplate with an inner EPDM seal preventing any leaks. The baseplate has a number (1-12) of 10mm restrictive flow holes bespoke to the project. The flow restrictor has no moving parts, hugely reducing the need for maintenance or risk of failure.

The JG Graves Woodland Discovery Centre is being constructed in the Ecclesall Woods Sawmill as part of the Sheffield Woodlands Environment Enhancement Project.The centre runs craft courses all through the year from cider making to wood work skills. Public events in the autumn and spring celebrate Sheffield’s rich woodland heritage and demonstrates the unique facilities of the centre, as well as providing activities such as story telling, discovering nature and traditional uses of wood in the home and garden.The SolutionThe project entailed designing a center that harmoniously blended with the enchanting surrounding woodlands. The main building featured a grand ‘ski slope’ style roof, initially planned to be waterproofed using metal sheets. However, the client quickly realised that this approach would be prohibitively expensive.To meet the client’s requirements for a cost-effective alternative that maintained the intended appearance, they turned to Charlesworth Contractors—a Polyroof approved contractor with a proven track record of excellence. Recognizing the need for a swift and efficient waterproofing solution, we recommended the BBA Approved Polyroof 185 System with Lead Roll Effect trims.The first step involved fixing high-quality plywood boards onto the roof’s support beams to create the ski-slope shape. This foundation was then enhanced with GRP trims meticulously applied to replicate the appearance of traditional lead rolls. Finally, our renowned Polyroof 185 System was expertly installed, swiftly forming a seamless and highly durable waterproofing membrane.The implemented solution not only met the project’s time constraints but also exceeded expectations in terms of performance and aesthetics. With a 20-year insurance-backed guarantee, our Polyroof 185 system provided the client with peace of mind, assuring long-lasting protection for the roof. Furthermore, not only did our solution prove to be an attractive alternative to metal sheets, but it also offered significant cost savings.The successful collaboration between Polyroof, Charlesworth Contractors, and the client resulted in a waterproofing solution that seamlessly blended into the natural surroundings of the woodlands. Our advanced liquid roofing system, coupled with expert craftsmanship, delivered an outcome that was both visually appealing and economically viable. With the Polyroof 185 System, we demonstrated once again our ability to provide efficient, durable, and cost-effective solutions for even the most challenging roofing projects.

Container City is an outstanding example of upcycling architecture in the London Docklands. The buildings are constructed from old shipping containers that have been refurbished and then fixed and welded together, creating an innovative modular building solution that houses offices.The roofs had been waterproofed with an EPDM membrane as part of an inverted roof design, however due to failings within the roof coverings leaks were occurring.It was also felt that the inverted roof insulation was unable to provide satisfactory thermal performance, leading to excessive fuel bills during winter. The architect responsible for finding a solution used Polyroof’s Solution Finder Tool to quickly find a recommendation for improving the thermal properties whilst providing long-term waterproof protection. Equipped with the key information needed, the architect specified the Protec Warm Roof System for the roof refurbishment works.Polyroof Technical Services carried out a full technical survey of the existing roof to identify all existing issues and provide a full set of recommendations. One of the key drivers for the refurbishment was the ability to easily access the roof membrane to carry out regular cleaning and maintenance works, so the specification included for converting the roofs from an inverted roof to a warm roof design.Polyroof Approved Contractor A R Roofing Ltd began by stripping away the old inverted roof components and the failed EPDM membrane to expose the metal roofs of the containers below. A self-adhesive vapour barrier was then laid onto the metal decks and Polyroof RES Insulation (T&G) was bonded on top using PU adhesive. Lastly, the Protec system was laid direct to the insulation boads to create a seamless, smooth and long-lasting finish that came with a 20 year insurance backed guarantee. This striking piece of upcycled architecture now has a roofing solution to match the innovation behind its creation.

It was selected because of its thermal efficiency and suitability for use with living roof systems. Partnered with ProTherm’s excellent insulation, the complex timber roof now boasts a waterproof system that is BBA Certified to last the lifetime of the building.The wooden structure evokes the ships that once sailed into West India Dock and provides a warm, natural counterpoint to the steel and glass towers of Canary Wharf.And with Radmat’s high performance products and lifetime guarantee, the green roof terrace at Crossrail Place will be a living oasis in the heart of London’s financial district for years to come.

A good example of the before and after effects of laying a sedum roof garden and accompanying deck and paved area onto a small domestic roof terrace. All these products are designed to sit on top of the waterproof membrane (in this case single ply) there was no issue of damage to the roof. The support pads lifted the decking off the roof, eliminating the risk of the timber piercing the membrane, and drainage was maintained through the roof surface since the green roof system has a cavity beneath its own reservoir and drainage layer to allow water run-off.

The new £8.5m Allam Diabetes Centre at Hull Royal Infirmary plans to treat and care for patients with diabetes and metabolic bone diseases.It also includes a significant amount of clinical research facilities supporting not only diabetes and endocrinology, but also vascular surgery, neurology and other research departments. Its curved towers flank a glass entrance, which leads to a large waiting area and reception. Spread over three storeys are consulting rooms, specialist treatment rooms, office space and changing rooms as well as a roof terrace on the second floor. Designed to achieve a BREEAM rating of ‘very good’, the thermal performance of the insulation specified for the Allam Diabetes Centre’s flat roof was hugely important. Another crucial factor was fire safety. Although the application doesn’t fall under current fire regulations banning combustible insulation, the architect specified that only non-combustible materials should be used during construction.  Main contractors Zenith Developments appointed specialist contractors Fosters Roofing to install the roof. They in turn tasked DANOSA UK with supplying all the materials for the roof construction, including the insulation. “The build-up of the Allam Diabetes Centre was a single-ply warm roof with a tapered insulation scheme to provide the fall required for rainwater run-off,” explained Steve Downey, Commercial Director at DANOSA UK. “Tapered insulation schemes are always more difficult than traditional flat roofs, so we asked Knauf Insulation for technical advice on how to achieve the required U-value of 0.18 W/m2K.” The Knauf Insulation Technical Support Team recommended Rocksilk® Flat Roof Slab. It is BBA certified for use on mechanically fixed flat roof build-ups and is suitable for all types of roof deck.  As well as excellent thermal performance, Rocksilk® Flat Roof Slab is non-combustible with the best possible Euroclass A1 reaction to fire classification. It also provides excellent sound absorption so will help reduce the drumming effect of rainfall.  Rocksilk® Flat Roof Slab contains a special water repellent additive and is manufactured using Knauf Insulation's Krimpact® Technology which provides high levels of compressive strength and durability. As the project was a tapered insulation scheme, Rocksilk® Flat Roof Slab was manufactured to order to ensure the correct fall was created. The tapered insulation scheme wasn’t the only challenge with the Allam Diabetes Centre – it also features a curved façade, which added complexity for the installation team at Fosters Roofing.  Paul Foster, Managing Director at Fosters Roofing said: “Insulation needs to be carefully cut to the exact shape of the building otherwise heat can escape making it less energy efficient. Thankfully Rocksilk® Flat Roof Slab was easy to cut and quick to install, so it wasn’t a problem.” Rocksilk® Flat Roof Slab has also been designed to knit together during installation so there are no gaps that could affect thermal, fire or acoustic performance. By using Rocksilk® Flat Roof Slab, Fosters Roofing and DANOSA UK were able to achieve the required specification for the tapered insulation scheme on the new Allam Diabetes Centre. This will contribute to the energy efficiency needed to achieve the BREEAM ‘very good’ rating.

Boughton’s Intensive green roof substrate has been successfully trialled in a ground-breaking analysis project at Coventry University assessing the feasibility of ‘greening’ landscapes with ecological beneficial habitats.  With the objective being to research the benefits and plausibility of incorporating green space and wildlife-friendly habitats into heavily built-up areas, Coventry University handpicked Boughton’s Intensive IN1 substrate based on its nutrient content, weight, and the inclusion of a water supply in chambers beneath the sub-base.The majority of green roofs in the UK fall into the ‘extensive’ category and are based on a low growing succulent, Sedum, which only requires a few centimetres of substrate to grow, whilst intensive green roofs provide a deeper soil depth and can support a more complex plant system. To this end, Coventry University wanted to explore the advantages of intensive green roofs, which offer greater biodiversity, often create accessible spaces, and offer the best insulation properties and storm water management. The organisation partnered with SEL Environmental, who provided its intelligent water management systems for the project.Boughton’s Intensive IN1 substrate boasts greater organic content than extensive substrates, meaning it supports larger plants and can be installed at greater depths, varying from 100-500cm. IN1 provides a stable growing medium for wide variety of plants in intensive green roof installations, including green roof lawns, shrubs and trees.Depending on the substrate depth and plant type, permanent irrigation systems (above or below ground) are sometimes installed with this substrate to as a backup for extended dry periods. They are not required for everyday irrigation, as the substrate has the ability to hold onto sufficient moisture during ambient conditions. The project, funded by Knowledge Transfer Partnership (KTP) and headed up by Sophie Barron-West, followed plant growth for four years from 2017, with a break due to Covid 19. Dr Stephen Coupe and Dr Liz Trenchard from the University’s Centre for Agroecology, Water and Resilience (CAWR) offered their research expertise.CAWR’s Dr Stephen Coupe says: “The technical requirements of Boughton IN1 were a big part of why we chose it. We also wanted the chance to get as many wildflowers in the space as possible. The nutrient levels were perfect because it wasn’t too rich. In fact, it was a ‘just right’ formulation that wasn’t going to overstimulate but would also deliver enough nutrients for what we needed. Ultimately it was going to be perfect for long-term sustainable plant growth.”He continues: “Reliability was another consideration because we knew we could get it delivered on site on time and, because of Boughton’s location in Kettering, we weren’t concerned about lead times, so that was a plus. It’s safe to say it was a studied choice.”Ground-breaking resultsAccording to the University, the trial resulted in ground-breaking analysis into how different types of green roofs can be created and maintained, as well as what their benefits would be alongside others in a built-up area.  The project successfully demonstrated the ecological impact of placing retrofit green roofs onto existing infrastructure, even with a focus on wildflower species and a relatively short development time. An independently-conducted ecological survey recorded five insect species that have national and local rarity value, including two species of bee that are deemed ‘nationally scarce’ and ‘nationally rare’. Of 457 preserved specimens taken on the green roofs at Coventry University, a total of 120 different insect species were recorded, including wasps, sawflies, hoverflies, beetles, and as many as 11 species of bee.  Coventry University’s findings revealed that the innovation in green roofs has improved and increased the total constructed habitat for rare insects. Research has also enabled better water management alongside habitat enhancement. This research has been incorporated into SEL’s product range, where green roofs are now used across four sites in Coventry, London, Aylesford and Blackburn. CAWR’s Dr Stephen Coupe said: “Ecology, biodiversity and wildlife are largely forgotten by planners, designers and builders in developments. Most green roofs installed in the UK are based on sedum, and, while there are additional features that can be added to these green roofs to improve biodiversity, they are rarely incorporated. Our findings, using Boughton’s Intensive green roof substrate, are that the retrofit of green roofs is feasible and, more than four years into development, IN1 has supported verifiably diverse green roofs. The plants on these roofs supported several insects that have rarity status in the UK, which is very positive.” Dr Coupe adds: “Whilst it is probable that substrates take many years to develop anything like the maturity comparable to natural soil, after just four years, IN1 went from having no recordable eukaryotes, to a concentration of organisms, including worms, soil mites and rotifers.”  Boughton Business Development Manager, Jason Lock comments: “Boughton was delighted to be part of this groundbreaking project and buoyed by such positive findings. Our products have been used successfully in a number of iconic green roof developments around the country over the years but it was a pleasure to be involved in such an important trial that would deliver verifiable results assessing the potential for green roofs to create new habitats in urban environments and enhancing local ecological diversity. Boughton offers an extensive range of green roof substrates and we welcome any research that helps further innovation around the application of green roofs.” The experiment at Coventry University is ongoing and the team are set to feed back again at the end of the summer about how prolonged dry weather has affected results. Dr Coupe says: “The beauty of this project is that there is no general timeline for a piece of green space. We need funding to support our ongoing investigations but there are options and opportunities for long-term research. It can last for the lifespan of the site and I think we will see really interesting developments. There is no reason why, over time, these green spaces would be indistinguishable from an existing habitat.” Boughton’s portfolio of green roof substrates are specifically engineered for different types of roof greening, both for domestic and commercial projects. A full product specification is available for each of Boughton’s Green Roof Substrates, and other landscaping products, making exact specification simple and straightforward. There’s also a section on each product listed online, titled ‘to specify (copy & paste)’, designed to make your job even easier. To enquire about your next project, contact Boughton by calling (01536) 510515 or email sales@boughton.co.uk.

The largest SolaGlide retractable glass roof in the UK is the talk of the town! Installed by Breezefree at The Hawk's Nest in London’s Shepherd’s Bush.Working with the team at Birdhouse London, we were presented with the challenge of transforming their outdoor space at The Hawk’s Nest into a flexible all-year space, whatever the weather. Challenges included satisfying the requirements of TfL due to the tube line running immediately above, as well as the venue’s request to have a space to trade in during construction work.The result is a chic hospitality space with a sliding roof that offers options for open airiness or full enclosure from the elements. The roof also offers significant soundproofing, reducing impact on neighbours on their most lively nights. The transformation means that the venue can offer their delicious cocktails, and pizzas that have to be tasted to be believed, underneath an elevated and stylish roof that will help draw diners and revellers for years to come.

The five-star Cameron House Hotel is set within 400 acres of beautiful Scottish countryside on the world-famous banks of Loch Lomond. The Hotel is the prestigious home to a collection of 140 bedrooms including 24 suites. The hotel offers a variety of dining experiences, including the Michelin starred restaurant Martin Wishart at Loch Lomond.When the flat roof areas above the main kitchen and the dining area began to leak, it was imperative that a rapid waterproofing solution could be found that could be installed without disturbing operations at the restaurants below.When the flat roof areas above the main kitchen and the dining area began to leak, it was imperative that a rapid waterproofing solution could be found that could be installed without disturbing operations at the restaurants below. The roof area itself was covered with an aged felt membrane that had been treated with a variety of localised repairs which could no longer prevent water ingress. A large amount of M & E plant was present throughout the roof, and any new waterproofing system would be required to seal the numerous stanchions and plinths in a fully weatherproof condition. After researching waterproofing systems online, Cameron House Hotel contacted Polyroof Technical Services for a recommended waterproofing solution that met their stringent criteria. Following discussions, the regional technical manager carried out a detailed roof survey of the roofs. The survey report formed the basis of a bespoke specification that covered a comprehensive set of recommendations to fully solve the roof’s problems.Polyroof Approved Contractor Skyform Roofing successfully tendered the project and the refurbishment works soon began. In order to avoid disruption to the hotel’s operations the existing roof coverings were retained as a substrate for the Protec system, without the need for stripping / replacement works. Due to the complex nature of the roof, works were carried out within a phased approach with the most problematic regions being refurbished first. Loose-laid M & E plant was relocated and the felt coverings cleaned and made good as required. The remaining roof details were then prepared as necessary before being primed ready to accept Polyroof’s cold liquid-applied Protec system.A key advantage of the Protec system for phased refurbishments is its speed of application and rapid curing. Unlike moisture-curing liquid systems, Protec forms a solid, extra-tough membrane that can be walked on 30 – 60 minutes after application. Not only does this reduce labour times and keep costs down, but crucially it allows the full system to be laid in it’s entirety in a matter of hours – rather than days. With its fibreglass reinforcement, the Protec resin is able to rapidly mould around any protrusion, stanchion, plinth or upstand to quickly form a totally seamless watertight seal – without the need for any time consuming cutting or patching work. This meant that the many complex roof details were able to be rapidly made waterproof, further reducing installation times.The contract monitoring undertaken by Polyroof Technical Services allowed the contractor and manufacturer to work effectively together to ensure the roofing solution delivered on all the client’s needs. The application by Skyform Roofing was completed to a very high standard with every roof detail meticulously sealed in a fully weatherproof condition.

Another housing refurbishment is set to benefit from the high-performance Roofshield breather membrane. The world-renowned Roofshield membrane from the A. Proctor Group has long been recognised as a first-class roofing membrane solution, providing a pitched roof underlay that is air and vapour permeable.Specialist roofing company S & J Roofing in Bath has been providing roofing services since 1981 and has established a reputation for high-quality roofing work for all kinds of domestic and commercial works, from restoration to complete new re-roofs down to minor repairs.Naomi Richards of S & J Roofing commented, “we have used Roofshield on many of our projects, Roofshield will always be our number one go-to product. Using Roofshield leads to savings in both labour and material costs, keeping the installation team and customers happy. Roofshield was the most cost-effective solution to control the interstitial condensation in a pitched roof. Roofshield is the most reliable product on the market, so it is used on every one of our projects.”Roofshield is a unique, three-layer, nonwoven, spunbonded, polypropylene breather membrane with a patented melt-blown core, and it provides a secondary barrier to the ingress of rain, wind, and snow. Designed with a low vapour resistance, it is air-permeable, with the additional benefit that it eliminates the incidence of interstitial condensation in pitched roofs.The exceptional performance of Roofshield has been successfully incorporated in many of the most demanding locations worldwide. Its characteristics allow pitched roofs to breathe without needing air gaps or secondary venting. Its patented SMS (Spunbond Meltblown Spunbond) structure allows high levels of airflow and the transport of moisture vapour, making the formation of condensation in the roof space virtually impossible. Numerous vapour underlays use an airtight VP film layer to achieve their performance. However, the exceptionally high vapour permeability and air permeability of Roofshield means that it can perform in conditions in which air-tight alternatives will not.The exceptional air permeability performance of Roofshield means that the roof space will result in similar air changes to that of a roof using traditional eaves/ ridge ventilation. Therefore, another advantage of incorporating Roofshield into the roofing design is that it can lead to savings in labour and material costs due to removing the need for these vents as well as a separate VCL at ceiling level.
