"roof tiles"

This was the first asbestos roof coating project undertaken with Liquasil products, back in 2013. The roof was heavily soiled and was cleaned using a DOFF steam cleaning machine, delivering 150°c steam to completely kill moss and lichen spores. The metal fixings were treated with Liquasil's corrosion primer and sealed with Non-Sag Sealer before the whole roof was coated with Asbestoseal, the only BBA Approved asbestos roof coating.

“ARDEX have developed a range of tile fixing products that exceed expectations, and enabled us to maintain our reputation for excellence. We were delighted with the results at The Savoy”. Rafi Mimoni, MD Mega Marble

Stapehill Abbey is a unique estate of 45 two to five bedroom homes. Set within beautiful gardens and grounds, the recently converted Grade II listed refurbishment looks magnificent.The original Abbey House was built in the early 19th century, with the monastic buildings dating back to the 1840s. The twin chapels were designed by Charles Hansom in 1847 and the buildings were completed in 1851. Founded by a small group of nuns led by Madame Augustine de Chabannes, the Abbey was home to The Cross Abbey order of Cistercian Trappist nuns between 1802 and 1990.Dorset based developers Ankers and Rawlings worked painstakingly to retain the original artefacts and period features of this historical site. They chose over 60 Clement Conservation Rooflights for the project including both slate and tile profiles in sizes 1, 2, 3, 4 and 5.  Garry Hunter from Ankers and Rawlings said  “The homes at Stapehill Abbey have a mixture of slate and tile roofs, we chose Clement Conservation Rooflights as we needed a product that would look perfect in both. We are really delighted with end result and hope to use Clement rooflights again in the future”.

The Ascent Aluminium Roof Access Steps were specified to meet the clients requirement to create a safe access route up & over the “saw-tooth” roof for maintenance personnel. In this instance the Ascent steps were specified for use with an adjacent MSA Latchways climb-latch fall protection system. If collective protection is required handrails can be supplied to one or both sides of the steps. The Ascent Aluminium steps were specified for this project by Eurosafe Solutions Ltd a specialist fall protection company who also installed steps. The Ascent Aluminium walkway steps are tested for use on the aluminium standing seam roof and are secured back to the roof sheet using a proprietary support clamp. The Ascent aluminium walkway is designed in accordance with BS EN 516:2006 Prefabricated accessories for roofing, BS 4592, Industrial Type Flooring and stair treads, BS EN ISO 14122-3 Stairs, stepladders and Guardrail, BS 7976-2:2002+A1:2013 Pendulum slip resistance. And is manufactured under ISO 9001 and CE 1090 factory production control procedures, creating a walkway that is CE / UKCA compliant.The walkway steps can be configured with a handrail to withstand a loading of either 0.36 kN (general duty) or 0.74 kN (heavy duty) and can be supplied with an optional toe-board if required. The system can achieve these loadings without the need for additional bracing, allowing the walkway to be placed against the area to be accessed. UKCA / CE marked.

Can be supplied with a range of fixing kits to suit different roof profiles.

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.

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.

A roof at teh Jaguar Land Rover premises in Watford was in poor condition and suffering from cut edge corrosion. All of the loose and flaking factory finish was removed using 4000psi pressure washers and the rusted end and mid-laps were ground back to remove the rust. The cut edge corrosion was treated with Liquasil's corrosion primer and the entire roof was coated using the BBA Approved Metalseal.

A flat roof in the state of Tyrol was used to rigorously test a new non-combustible inverted roof insulation solution for the UK market.

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.

After first cleaning the roof and attending to rusted areas with Liquasil’s corrosion primer, it was the coated with Metalseal 20 from Liquasil, using airless spray equipment. The specification for this roof was for a special RAL colour. Only Liquasil can make silicone coatings in any RAL colour, so Metalseal 20 was specified for the project. This roof was completed in Forest Green.

Sonixx Resilient 250 was installed as an acoustic underlayment. It was bonded to the subfloor and a heterogenous vinyl and carpet tiles were installed on top. The installation was completed as part of a refurbishment to a bar and restaurant area within the hotel. Resilient 250 is a 2.5mm thick, high performing acoustic underlay manufactured using sponge rubber. It significantly reduces impact sound at the source, while also providing superb underfloor comfort. It is a versatile underlay and can be used below various floor coverings including carpet, carpet tiles, wood, laminate, luxury vinyl tiles, vinyl and ceramic / porcelain / natural stone tiles. At only 24kg (43 Ib) per roll, it is easy to distribute around site. Resilient 250 therefore facilitated a simple, quick, clean and cost-effective installation.

Heslington East Campus Student Residences: Sustainable and Efficient Expansion Alongside the preservation of listed buildings, the University of York is investing in a flagship £130m development for students that promotes wellbeing, community, and sustainability. The initial phase sees 16 brand new student accommodation blocks and 2 communal hub buildings providing flexible social spaces. Surrounded by stunning lake views and natural habitats, the buildings are part of a huge initiative to expand the student accommodation offering.GOALSArchitects Sheppard Robson alongside Graham Construction sought to futureproof accommodation by incorporating multi-use buildings, including catering outlets and social hubs. Key to the brief was using the latest in safety, energy efficiency, longevity, and warranty credentials. Graham Construction’s use of modular external sandwich panels, prefabricated steel bathroom pods, and pre-assembled services distribution racks used Modern Methods of Construction with off-site construction techniques.CHALLENGESThe major challenge was to specify a roofing system that could keep up with the pace of the build, given the typical building was constructed from start to finish in circa 14 weeks.The roof deck comprised of precast concrete slabs which facilitated the works programme for speed of construction and consistency in build quality.Alumasc’s challenge was to find not only a waterproofing solution that was able to keep up with such speed of construction but also to meet a truly sustainable life cycle equalling the lifetime of the building.A key consideration in the design was the roofing materials’ thermal properties. To meet the u-value target of 0.15, Alumasc’s XPS Plus insulation was specified, providing a single layer of 175mm, which reduced the height of the overall build-up when compared traditional XPS.SOLUTIONHydrotech 6125 Waterproofing System / Derbigum Hybrid Upstands For over half a century Hydrotech Monolithic Membrane has been successfully used by architects and specifiers, ensuring some of the world’s most prestigious buildings and structures are kept watertight. With no product failures in over 50 years and guaranteed waterproofing integrity for the lifetime of the structure, Hydrotech offers a total life cycle solution for the building.Hydrotech was specified on the main roof areas for this project as it easily meets individual requirements of the buildings. In addition, the system is designed to last the lifetime of the building or structure to which it is applied, giving long-term waterproofing integrity and no future replacement costs.Applied in a hot liquid state to the deck, and including a polyester reinforcement, the bond of Hydrotech MM6125 is 100% absolute. There is no risk of water tracking below the membrane and because it is monolithic, no possibility of lap failure.DERBIGUM WATERPROOFINGDerbigum sustainable roof system was selected for the upstand areas. This hybrid solution was developed to improve the thermal efficiency in all areas to mitigate against cold-bridging with minimal insulant thickness. Derbigum bituminous membranes are high-performance waterproofing systems offering extended warranties and the highest levels of project support. The upstand zones benefited from Derbigum Mineral which is a mineral surfaced composite reinforced membrane.ROOFTOP MANAGEMENT STRATEGYIn addition to the waterproofing solution the buildings benefit from the full Alumasc rooftop management service. This included the design and supply of safety systems, accessories, and over 20 AOV smoke hatches meeting all British and European standards.Specific safe zones were designed by Alumasc Roof-Pro and positioned around all roofs for safe access. Purpose made clips for installing lightning conductor tape without roof penetration were also provided. All rooftop accessories are part of the Alumasc Roofing specification and therefore can be found back-to-back within the Alumasc 35-year system warranty.PROJECT DATACompletion: Autumn 2022 BuildingType: Student Accommodation ProductApplication: Hydrotech & Derbigum waterproofing systems Certification: BBA Approved & European Technical Approval Architect: Sheppard RobsonMain Contractor: Graham ConstructionAlumasc Registered Roofing Contractor: Tandragee Roofing

As described by the Woodland Trust, Glen Finglas is a great expanse of ancient woodland, lochs and open heathland, sitting at the heart of Loch Lomond and The Trossachs National Park and home to one of the best examples of upland wood pasture in Scotland.The newly constructed Gateway Building was designed to blend in with the surrounding woodlands and featured a circular timber-clad exterior with a spiralling, curved roof. The Woodland Trust approached RTA Building Limited, a Polyroof Approved Contractor, to provide a guaranteed waterproofing solution that would complement the aesthetics of the building.After comprehensive discussions and careful evaluation, we recommended the Polyroof 185 Warm Roof System for this unique project. This system stood out due to its exceptional BBA 30-year durability rating, impressive life-cycle costing performance, and an insurance-backed guarantee that offered the client peace of mind.The implementation process involved the meticulous installation of the Polyroof membrane, which flawlessly covered the flat roof areas while seamlessly following the curved perimeters and intricate spiral design. To ensure a fully waterproof edge detail that complemented the building’s contours, we installed a bespoke GRP capping. This robust combination provided Woodland Trust with a reliable and long-lasting roofing solution.Through our collaboration with Woodland Trust, we successfully implemented the Polyroof 185 Warm Roof System, delivering a durable, and cost-effective roofing solution. Our system’s exceptional durability rating, long-term life-cycle costing performance, and insurance-backed guarantee provided Woodland Trust with the confidence that they had chosen a roofing solution that would stand the test of time. With Polyroof, Woodland Trust achieved a seamless, reliable, and environmentally conscious roofing solution for their unique project.

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.

New school construction with biosolar wildflower roof system. Selection of sedum and native wildflower species pre-planted into M-Tray modular green roof trays for fast and easy access to and installation on single ply roof membrane. Client increased thermal insulation, reduced rainwater run-off, achieved energy savings, protected the waterproofing membrane and attracted wildlife to the roof space.The wildflower / PV roof system will feature in students' learning projects in the future.

The roof project in Bermondsey consisted of an accessible green roof for residents on the first floor and a green and brown roof at the next level. Natural Aggregate, 6mm Barley Beach. London

This project involved a brand new Starbucks drive-thru being built in West London where the customer wanted the overlooked rooftop to be green. The customer was able to give the basic dimensions to our team and describe how they wanted the roof laid out. We then calculated the exact quantity of units needed with our inhouse software and gave delivery and installation guidance to the contractor and end client. Wallbarn also supplied the materials for the semi-extensive border including geotextile fleece, drainage board and our specially-developed substrate for a comprehensive green roof solution,

The proprietors of this domestic property in Harrogate added a large extension with a total roof area of 150m2. The client wanted the new roof sections to complement the slate work and aesthetics of the original building whilst adding a contemporary and stylish look to the extension.Originally considering a zinc sheeted roofing system, the client explored alternative materials that could achieve the same visual impact but at lower cost. After discussions with Cure Roofing Ltd, a Polyroof simulated metal finish was proposed as a roofing solution that would meet all the client’s requirements.Not only do Polyroof’s range of liquids offer cost savings over traditional metals, but they are also lighter in weight, totally seamless and can be pigmented to any RAL colour. Having no scrap value, the client also had the added peace of mind that the roof would not be a target for theft.A timber warm roof was constructed which incorporated 120mm PIR insulation to achieve a U-Value of 0.18 W/m2K in compliance with building regulations. An OSB3 TG4 deck was fitted above the insulation and Polyroof pre-formed GRP standing seam trims were fixed at 600mm centres into the deck. Next, the first coat of the Protec waterproofing system was applied over the whole roof area and encapsulating the standing seam trims. The roof was finished with a second coat of Protec pigmented to RAL 7016 providing an anthracite grey colour to the whole roof, accurately simulating the appearance of zinc roof sheets.The workmanship by Polyroof approved contractor Cure Roofing was second to none and the quality of the finish left the client delighted with their new roof. With BBA approval, top-rated fire performance and Polyroof’s trusted 20 Year Accredited System Guarantee, the client has total peace of mind that their new extension could not be better protected for decades to come.

This asbestos roof is being cleaned using a closed box pressure wash, with all waste water being filtered and recovered for re-use. Once cleaned, the roof is coated with the BBA Approved Asbestoseal system which includes: SWT CORROSION PRIMER - fully rust and wet tolerant, the primer is applied to all metal fixing to stop further corrosion. NON-SAG SEALER - is applied to all fixings and small holes and cracks to permanently seal them. ASBESTOSEAL 20 is brush applied to the roof sheets to provide a new finish.

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.

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.

Friesland Campina CHALLENGE An absolute must for refrigerated warehouses or dairy processing facilities is to try to keep the building as cool as possible and to avoid all causes of heat, in order to keep the cooling costs as low as possible. Some decisions can have detrimental effects though. Mechanical fixing of the roofing membrane for example, in case the wrong fastenings are used. Thermal bridging may cause cold – or in this case heat - penetrating through the flat roof fasteners resulting in higher energy bills. And, quite important as well, mechanical fixing will perforate the vapour control layer, which in the case of cool buildings sits uppermost on the insulation. The result being moisture-related damage to the insulation! Furthermore, it has also been proved that the darker the roofing membrane, the less the sunlight will be reflected, the more heat will be absorbed. Again resulting in escalating energy costs. Waterproofing a cool storage warehouse is definitely not easy! In this regard Friesland Campina were looking for a durable and ecological roof solution for their brand new refrigerated distribution centre in Maasdam. SOLUTION RENOLIT came up with the perfect answer: the RENOLIT ALKORBRIGHT cool roof membrane. Here’s why! RENOLIT ALKORBRIGHT is a completely white PVC membrane reflecting the sunlight up to 90%. Absolutely the highest solar reflectance rate ever. Thanks to this membrane, which prevents the interior from warming up, there will be no extra air conditioning expenses. In addition, an extra protective coating makes sure less dirt sticks to the roofing membrane. This layer will in turn help to maintain a durable reflection. 

The British Museum opened its doors in 1759. Now home to some 8 million works from a number of different cultures, the museum stands as an iconic London attraction. The Museum made the decision in November 2013 to replace the restaurant’s old flooring, as it could no longer handle the vast number of visitors. W B Simpson Ltd, was the chosen tiling contractor to complete the new installation. Marc Poland, Director at W B Simpson Ltd said “The architect consulting on this project specified we use ARDEX UK’s products. Their high performance adhesives are typically the preferred choice of architects.”

A DOFF steam cleaner was used to thoroughly clean the moss and lichen from this asbestos roof in Bridgwater. The metal fixings were treated with Liquasil's rust tolerant primer and then sealed, along with cracked sheets, using Non-Sag Sealer, before the whole roof was coated using Asbestoseal 20. The end result was a leak-free asbestos roof that will last for many more years. Asbestoseal is the only BBA Approved coating system for asbestos roofs.

Eastbourne station is located in East Sussex. It was originally built in the 19th century and is classified as a Grade II listed building. Over the years, the station has undergone several renovations and upgrades.Back in October 2020 it was announced £5 million would be spent on restoring Eastbourne Railway Station to its ‘former glory’. Work done includes canopy refurbishment, slate roof replacement, masonry work to the front of the station, and new roofing above the atrium.Twinfix were approached to replace the glazing panels on the 32 lanterns on the station’s train shed with something hard wearing, sustainable and modern but without losing the period look. The change was needed because, according to the plans, the existing fixtures were ‘life expired and inefficient’.Twinfix supplied their Multi-Link-Panel Non-Fragile (NF) roof glazing system, glazed with 6mm solid obscure polycarbonate. The new glazing spanned 1243 square metres and was installed by Gable, on behalf of Main Contractor BAM Nuttall.The Multi-Link-Panel NF system is an innovative roof glazing product that has been well utilised for many years on station canopy roofs, and it has been thoroughly tried and tested in that time.It was the chosen system for this project for a number of reasons:sustainability– these panels are virtually unbreakable in manufacture, transit and in situ, meaning that, unlike glass, maintenance costs will be eliminated. The system is also completely recycleable.safety– Twinfix Multi-Link-Panel NF (Non-Fragile) conforms to the HSE recommended test method ACR[M]001:2019 (as outlined in document HSG33) and achieves a ‘B’ Classification.off-site construction– The panels are pre-assembled in Twinfix’s factory ensuring strict quality guidelines are adhered to, which is not always guaranteed when roofing products are assembled on site.ease of access– The Multi-Link-Panel NF system can be fitted with In-Line Access Hatches, to allow cleaning of gutters and roof. These hatches are hardly visible and allow safe access through the glazing without needing to get on the roof.weight– The Multi-Link-Panel NF is light in weight and due to its modular format, it is very quick to install which allows for short rail possession works. A slight redesign of the original roof allowed 96 access hatches to be installed, making maintenance easier. Installed it’s almost impossible to detect the modern materials that have been used to bring this historic structure back to life.During the renovation work, Shaun King, Sussex route director for Network Rail, said, “The quality of work on site is being completed to a very high standard and we’re taking great care to restore the Grade II listed building to its former glory.”

Topseal PU was specified over numerous roofs on this hospital covering 1000's of metres. Topseal PU was chosen due to its BBA certification, high performance, 25 year guarantee, low odour together with the failed asphalt roofs and amount of plant on the roof it was the perfect product.

Flat roof waterproofing in the UK

The Protec System was used to waterproof the domed green roof areas of this striking, sustainable house development which was featured on Chanel 4’s Grand Designs. With an ambitious vision and a tight budget, Robert and Milla Gaukroger set about transforming a dated 1980’s house overlooking Lake Windermere into a state-of-the-art, eco-conscious home. Since the house lay in beautiful hillside surroundings, in order to blend into this setting, the domed roofs of the house were to be covered with a wildflower meadow mix to provide a green roof construction.The SolutionThe Protec System was chosen as a waterproofing membrane for the roofs as it is ideally suited for green roof applications. Lightweight, flexible and highly durable, the system can easily accommodate structural expansion movements and is tough enough to resist root penetration. The Protec system was applied to over 350m2 of domed roof to provide a long-lasting waterproofing membrane.The key reasons why Eastleigh chose Protec are the same reasons that has seen it become one of the fastest growing cold-applied liquid roofing systems in both the new build and refurbishment markets. Combined with the timber cladding to the verticals of the building, the finished aesthetics of the development blended seamlessly with the surrounding areas.A warm roof build-up that can be made waterproof at multiple stages:For larger projects the Protec system can be made temporarily waterproof at two stages prior to the application of the full waterproofing system. The first stage is upon installation of the sealed, aluminium-faced vapour barrier.The second phase follows the reinforcing of the foil-faced insulation board joints with Protec resin and taping mat. This enables a much more controlled approach to the installation with a greatly reduced chance of rain causing disruption and damage during the works.Highly flexible membrane:Regardless of the size of the roof, Protec forms a homegenous membrane, without a single joint or seam and without the need for any expansion joints.RapidCure technology for quick installation:The application of Protec as a liquid, through to the curing process where a solid, tough membrane that can be walked over, takes only 30 – 60 minutes. This enables large sections of the roof to be fully completed in a short space of time.Installing the Roofing SystemsThe Protec System provided waterproofing to all flat roof areas as well as the extensive parapet wall sections. The roof areas were made up of two designs: the Protec Warm Roof System (approx 7,500m2) and Protec applied to concrete as part of an inverted roof design (approx 1,000m2).The roof installation was carried out with a planned, phased approach that was synchronised to the wider construction schedule. For the warm roof areas, the first stage was to fill the troughs of the structural metal roof deck with acoustic insulation infills that will dampen external noise within the leisure centre. Next, the crowns of the deck were primed ready to receive the self-adhesive vapour barrier.The use of a high-performance aluminium vapour barrier not only eliminates the risk of condensation within the roof, but also provides temporary waterproofing protection, which is extremely useful on larger works such as this.The Polyroof RES Insulation boards, which comprised of a two layer system totalling 170mm to achieve a U-Value of 0.14 W/m2K, were bonded using high-performance PU adhesive to the vapour barrier. Following the wind uplift calculations it was determined that mechanical fixings were not required for this application – making for an extremely rapid installation. As you can probably imagine, fixing through 170mm of insulation into the crowns of the metal deck can be a tricky and time-consuming task.A key advantage of using a tongue and groove insulation system is that the finished surface of the roof is smooth and level without any unsightly board steps that can also lead to standing water issues. The insulation board joints were sealed using Protec resin with Polymat Taping Mat 450 which, in addition to providing additional strength to the joints, also creates a temporarily waterproof layer.For the inverted roof sections, Protec was applied directly to the primed concrete/screed surface. The membrane was inspected by Polyroof Technical Services, signed off and then covered with inverted roof components.

At Polyroof, we take pride in providing innovative liquid roofing solutions that meet the unique needs of our clients. From project conception to completion, our expertise lies in creating high-performance roofing systems that offer both durability and aesthetic appeal.This case study highlights our collaboration with Woodholm, a picturesque property located in Southerness, constrained by the Dumfries & Galloway Council Planning’s “room in the roof” design.The SolutionWoodholm’s owners were determined to create a home that would evolve organically while adhering to the council’s planning regulations. To achieve their vision, they enlisted the services of David Lamb Architectural Services to submit a Planning Application on their behalf, seeking approval for a modification from an existing apex roof design to a curved roof. After going through the rigorous process, the application successfully obtained full Planning Committee approval on 14 February 2017.To realise their desired construction, Woodholm’s owners had a preference for using wood and oak, aiming to incorporate these elements into the design. To accomplish this, they collaborated with Carpenter Oak Woodland, a renowned timber construction company known for their expertise in oak framed structures. The company skillfully designed an oak framed structure that perfectly met the owners’ requirements. By mid-November 2017, Woodholm had a stunning and aesthetically pleasing frame in place.However, finding an ideal roofing solution proved to be a challenging task for Woodholm. Initially considering a zinc roof, they encountered obstacles due to the prohibitive costs and the challenges posed by their maritime environment, as Woodholm is located directly on the shores of the Solway Firth. It was at this point that David Lamb’s initial positive impression of a roofing product caught their attention. Woodholm’s owners approached Polyroof’s simulated metal finishes with their needs and were introduced to the Polyroof technical team. The team guided them through the necessary technical specifications to meet the Scottish Building Warrant for a Warm Roof, ensuring compliance with the required standards.Fortuitously, Woodholm’s owners discovered that Polyroof would be exhibiting at the “Homebuilding & Renovating Show” from 21-22 October 2017. At the event, they had the opportunity to meet the Polyroof team as well as Contractor, Kenny Scott of LK Roofing, Lochmaben. The Woodholm team was highly impressed and reassured by the collective experience, knowledge, and technical expertise demonstrated by Polyroof and LK Roofing. Equally important, they appreciated their ability to attentively listen to and understand their concerns.Following the show, a site meeting was promptly arranged with LK Roofing, allowing all parties to discuss the project in detail. As a result, a comprehensive and competitive quotation was provided, falling comfortably within Woodholm’s budgetary requirements.By early December 2017, Woodholm’s joiner had installed the sub-decking, which served as the foundation for the roofing system. LK Roofing then expertly applied the Alutrix membrane, a high-quality waterproofing layer, providing Woodholm with a watertight working cover.Thanks to our collaborative efforts with Woodholm, the project achieved a seamless integration of their desired curved roof design, wood and oak elements, and our advanced liquid roofing system. Woodholm’s owners were delighted with the final result—a beautiful, organically evolving home that not only met their needs but also exceeded their expectations.At Polyroof, we are dedicated to providing roofing solutions that offer both outstanding performance and stunning aesthetics. The Woodholm case study is a testament to our commitment to delivering innovative products and excellent customer service, tailored to meet the unique requirements of each project.

IKOpro Acrylic Roof Coat has been used to provide a quick (taking only 4 days to complete) and seamless waterproof solution to a leaking roof at Bellman’s Auctioneers & Valuers in West Sussex. Contracts Manager for M Holmes Construction (contractor) admits that it was much less labour intensive than traditional roof refurbishments. He said, “The beauty of this system is that you don’t have to re deck the roof, unlike some alternative liquid systems. So this means you save one day of labour, typically four men on a job this size, plus material costs.”

One of the roofs within the scheme, Hodge Clough School in Oldham, had fallen into a dilapidated state of disrepair and was in great need of replacement.
