"roofing"

Counting about 3,000 residential properties, Glenvale Park is a brand-new neighbourhood in the north of Wellingborough. To cater to the local community’s educational needs, the project also includes a new nursery school and primary school. Together with single-ply specialist Rock Roofing and main contractor Lindum Group, Soprema took care of the pitched and flat roofs of the educational facilities, waterproofing 3,000 square metres with the aesthetically stunning FLAGON membranes.ONE SITE, TWO PROJECTSSoprema secured the Glenvale Park project in October 2022, providing its developers with a significant commercial advantage over competitor solutions. The actual construction of the Glenvale Park nursery school started in January 2023 and was soon followed by works on the primary school. So, the project consisted of two separate buildings located on the same site, with the same client and main contractor overseeing both endeavours simultaneously.Soprema not only supplied the necessary waterproofing and insulation solutions: our team of experts was also responsible for interim site inspections, thermal calculations, and other services – always in close collaboration with Rock Roofing.Leon Horobin, Technical Sales Manager at Soprema, greatly values the longstanding relationship with Rock Roofing: “We have worked with the company founders, with Contracts Manager Steve Hatcher and with other members of the team for almost a decade. The level of collaboration has always been outstanding.”OVERCOMING NUMEROUS CHALLENGESSteve Hatcher stresses that the quality of roofing works for Glenvale Park nursery and primary schools benefited massively from the strong partnership between Rock Roofing and Soprema. Steve: “We relied on Soprema’s valuable on-site assistance and leveraged the expertise of their technical professionals to resolve the issues we encountered – and there were quite a lot of them, making the project all the more engaging and interesting for the team.”1.   DESIGN CHALLENGESThe first challenges arose from the fact that we were not working on a flat but on a pitched roof, requiring careful thought and planning. The detailing becomes more complex as the angles of the profiles change, and working on a slope is also challenging in general as it makes installing the sheets and products trickier.2.   CHALLENGING WEATHER CONDITIONSThe winter season, too, posed a challenge at the start of the project. The light snowfall and rain made the roof wet and slippery. Moreover, the low temperatures prevented the use of adhesives and a lot of the work had to be put on hold. This initially resulted in delays and increased deadline pressure. However, we were able to overcome these setbacks and make up for lost time when it became warmer.BENEFITS OF WORKING WITH SOPREMA1.   INCREDIBLY WIDE RANGEBoth fully adhered and mechanically fixed systems were used for the Glenvale Park schools, testifying to Soprema’s extensive product range and showcasing our ability to tailor solutions to the most diverse roof situations. We can select multiple products from our range to meet client needs and cover cost considerations. Moreover, the roofs being highly visible and their aesthetics a major selling point, we ensured that our solution added to their visual appeal.1.1 Cost-effective alternative to metal roofingFor the visible roofing areas, we used single-ply membranes while adding profiles to make them look like standing seam roofs. The result looks as stunning as a metal roof yet is much more durable with a product life of more than 35 years. In addition, our synthetic roofing membranes are recyclable, easier to install, more cost-effective and much lighter than aluminium, lead or copper roofing. The lower permanent load results in additional cost savings because the roof structure can be lighter as well.1.2 Fully adhered systemOn the pitched areas, which are very visible, we used fully adhered membranes to obtain a beautiful flat appearance. More specifically, the build-up is FLAGON SB, our fleece-backed membrane composed of flexible PVC, on top of SOPRATHERM G, a glass tissue-faced PIR insulation. The self-adhesive SOPRAVAP STICK ALU 16 membrane served as a vapour control layer, and the metal deck was primed with ELASTACOL 600 primer.1.3 Mechanically fixed systemsFor areas that were not visible, we opted for two mechanically fixed systems. As achieving the same flawless surface as the fully adhered system was not necessary, quick installation and cost-effectiveness (especially since no adhesives are required) were the deciding factors.The first mechanically fixed area consists of FLAGON SR DE, SOPRATHERM F insulation and a VAPOR FLAG vapour control layer. The second area has the same build-up, but with tapered insulation to create falls in the roof to the outlets.1.4 Solar PV and roof lightsThe roofs of Glenvale Park nursery school and primary school have been fitted with solar PV panels. Rock Roofing took care of their integration into the roofing system and installed remote and temperature controlled roof lights on the nursery school. Steve Hatcher: “It really is an all-encompassing package you get. Only a big supplier like Soprema has the different products you need for optimally waterproofing and insulating multiple roof areas.”2.   ONE-STOP SHOP AND WARRANTYAn additional advantage of having one supplier for the entire build-up is the reassurance that all products, which are designed as a system, are fully compatible. Moreover, you get a single-point warranty. For the Glenvale Park schools, we even extended our standard 20-year Sopracover warranty to 25 years. Finally, all the fire requirements of BROOF(t4) are of course covered.EXCITING PROJECTS AHEADBoth the nursery and the primary school have been completed. The buildings look stunning and perform excellently. The complexity of this project is what makes it stand out, showcasing the advantages of employing a complete system tailored to unique installations. And more exciting collaborations between Rock Roofing and Soprema are in the pipeline.Interested in our one-stop shop approach for your own project?

We all know warm roofs and joist zones are huge areas for air leakage and extremely hard to solve this problem. This warm roof structure for luxury apartments retrofit fit onto an already existing block of apartments in Tottenham was typically the icing on the cake for detail and performance. With the hand cut roof providing the client with multiple skylights, dormers and 360-degree turrets, this was going to be no easy task of getting the airtightness and vapour control secure and correct in a traditional method. Step forward Passive Purple! Rather than just covering the issues, once the hand cut roof was finished, the 220mm roof rafters were filled with a layer of spray insulation supplied by Lapolla UK. The dormers, skylights and turrets were then given some attention to detail with Passive Purple BRUSH before the final application of Passive Purple (spray applied) This gives this roof a complete airtight vapour control with performance like no other and getting around all of them circular details and angle’s galore this was just another simpler, easier way to get the job done right and guaranteed! Passive Purple liquid application saves the client and user so much time and so much less strenuous labour.

Canberra HouseBauder Cold Applied LiquiTOP SystemSynopsisCanberra House is an office facility in Swindon. The existing single ply PVC waterproofing system roof was leaking and so Bauder carried out a full site survey. The resultant report gave the client several options to rectify the leaking roof.Bauder Building BoardProject nameCanberra HouseLocationSwindonProject typeRefurbishmentRoof size985m²SpecifierRapleys LLP (Bristol)Approved contractorCentral Roofing & Building Services LimitedThe specificationThe LiquiTOP system was chosen as it can be applied directly to the prepared and primed existing single ply covering. The liquid system allowed us to get into tight spaces and without the need for any hot works.LiquiTOP is excellent on refurbishment projects where the complexity of the roof involves intricate areas to be detailed that are not easily achieved with a sheet membrane, or the actual working space on the roof is constricted.Project challengesLarge areas of plant and machinery were situated just above the roof level making access to the areas below difficult with the plant in-situ. The available budget on this project did not allow for lifting or removing the plant, stripping the existing waterproofing system, and replacing with new. Therefore, the decision was made to overlay the existing single ply membrane with a cold applied liquid waterproofing which can be installed without the need to raise any plant.To overcome drainage challenges, secondary upstands were created under the plant and fabricated channels placed underneath allowing water to flow through to the drainage points.The resultBauder was able to offer a cost-effective solution without the necessity to remove or decommission the roof mounted plant and machinery. Cost reductions were achieved for the client by overlaying the existing roof, negating any need to strip existing materials, and not having to remove or raise the plant.The works were carried out by Central Roofing who manged the project impeccably and also finished ahead of schedule.System installedBauder Cold Applied LiquiTOP System1 LiquiTOP PU cold applied liquidA moisture triggered curing polyurethane waterproofing resin; applied in 2 coats, reinforced with Bauder LiquiTOP Glass Fibre Mat.

Wadham CollegeBauder Bakor 790-11 Hot Melt structural waterproofing system with BauderGREEN componentsSynopsisThe University of Oxford’s Wadham College graduate centre project was a complex refurbishment. Led by Lee Fitzgerald Architects and main contractor Feltham Construction it involved the careful restoration, adaptation and extension of the 1960’s grade II listed building.Bauder Building BoardProject:Wadham CollegeLocation:OxfordRoof Area:439m²Specifier:Lee Fitzgerald Architects​Main Contractor:Feltham ConstructionApproved Contractor:Deane Roofing & CladdingThe specification The brief for the project was to renovate the graduate centre and to link to the main college by creating a new entrance to the building. This led to the construction of a new building, the McCall MacBain Graduate Centre, which also now provides access to the Barbara Naylor rooftop gardens above the different reading, media and seminar rooms of the graduate centre. With the ageing existing waterproofing exceeding its life expectancy, the roof garden terrace was in need of a replacement roof system.As an accessible area which will experience a significant amount of foot traffic, the Bauder Hot Melt was determined to be the best solution for this roof. With a durability to match the expected life of the building and a self-healing system, the Bauder Bakor Hot Melt System is ideal for use on protected roofs such as inverted, paved, ballasted and terrace roofs.The resultApproved contractor Deane Roofing & Cladding carefully removed 439m² of the existing waterproofing, stripping the rooftop back to the concrete deck surface before installing the different layers of the Hot Melt system.The completed roof terrace now provides a modern and peaceful garden area where graduate students can relax and socialize between their work periods. Following several site visits by Bauder’s expert Site Technicians and a final leak test, a 20 year guarantee was issued for the roof terrace.System installed1 BauderPLANT E 42Green torch-on root-resistant capping sheet.2 790-11Hot melt rubberised bitumen asphalt with a percentage of post-consumer recycled materials that infills and fully bonds to all minor deviations in the deck.3 DeckPrimed concrete.

Working with Williams Roofing Contractors Ltd of Eastleigh, Hampshire, the winning project involved the refurbishment of a large water treatment plant that imposed stringent environmental and performance requirements.The outstanding workmanship and attention to detail by the Polyroof approved contractor during this large scale installation allowed this project to really stand out from the crowd. The below is a case study for this LRWA award-winning project, highlighting the many challenges and how they were overcome through innovation, workmanship and product choice.The SolutionFollowing a survey of the roof area conducted by Williams Roofing and Polyroof Technical Services, a detailed report was carried out after which a bespoke specification was produced and handed to the client. This document detailed a comprehensive set of recommendations for solving the issues that had arisen due to the aged condition of the roof coverings.The client, satisfied that the solution proposed would provide the lasting peace of mind they were looking for, awarded the contract to Williams Roofing Contractors Ltd to install the Polyroof Protec System.There were many challenges on this project as this was a live ‘Clean Water’ environment site, so all Williams Roofing Contractor staff on the project had to have the EUSR National Water Hygiene Cards and be fully inducted by Southern Water’s high standards. Working within these type of environments brings additional Health & Safety implications as the National Water Hygiene scheme is in place to ensure the protection of public health and promote safe drinking water practices. Further risks had to be considered and covered including the risk of working over open water areas with additional buoyancy aids on site to reduce the risks as described under CDM regulations.Williams Roofing Contractors Ltd had to be especially vigilant providing additional protection to ensure that no potential contamination or spills caused any contaminants to the clean water processes/water courses and environment with additional spill kits on hand. Due to the varying conditions of the roof construction(s)/substrates the preparation had to be thought through thoroughly. Certain roof areas needed to be scarified which would have caused reverberations through the roof/concrete deck. This would have possibly created contaminants by spooling of concrete/debris/dust to within the MF Compound Water Lanes/Tanks.

Cranbrook Primary SchoolBauder Total Roof System (BTRS) with Tapered insulation schemeSynopsisCranbrook Primary School in Ilford, London, was experiencing some major water ingress due to the advanced deterioration of the existing roof system. A roof survey was conducted by Stuart Parratt, Bauder area technical manager, where core test samples were taken to identify the existing roof construction to deck level and to provide an indication of the roof condition. The survey revealed that the existing waterproofing was in extremely poor condition, with extensive evidence of water ingress.  Bauder Building BoardProject:Cranbrook Primary School Location:LondonProject Type:RefurbishmentRoof Area:440m² Client:London Borough of Redbridge Council Approved Contractor:Thameside Roofing Ltd The specificationThe original waterproofing had been poorly overlaid with EPDM which had subsequently debonded. Before the installers could begin laying the new system, they had to strip the substrate back to the original asphalt. The client required a robust system that would deliver durability, value and longevity. 390m² of bitumen waterproofing, Bauder Total Roof System (BTRS), was specified for the main roof areas and 50m² of our cold applied liquid waterproofing, LiquiTEC, for an area that had limited upstands due to clerestory windows that could not be repositioned. Products appliedBauderPIR tapered insulation  A lightweight and cost effective alternative method of providing falls to a roof, whilst also providing thermal insulation. The client opted for this scheme at Cranbrook to minimise standing water on the roof. Bauder Total Roof SystemA two-layer bituminous waterproofing system robust enough to withstand foot traffic and most permanently sited plant. For use within warm and cold roof scenarios, as well as overlaying existing roofing materials. BTRS meets current UK Building Regulations Part B for external fire protection and features torch-free and safe to torch installation on combustible details. LiquiTEC Cold Applied liquid waterproofing Utilising Bauder’s PMMA cold applied liquid waterproofing on one of the roof areas ensured a fully watertight solution around rooflights and below upstands that could not be raised.  Project challengesAlthough the deck appeared to be in a reasonable condition for reuse as part of the refurbishment, there were large deflections to some areas and the existing waterproofing that overlaid the original system had been poorly installed and had pulled away from the asphalt below and so needed stripping prior to works commencing. The existing insulation was inadequate and left the building falling short of the current requirements. A thermal upgrade was incorporated into the works using a tapered insulation scheme which helped to solve the deflection issues by creating falls on the roof. To meet the minimum upstand requirements, the existing extractor vents needed to be removed to allow for the increase in the kerb height. Large continuous structural rooflights providing natural light to the building below were deemed thermally inefficient. The rooflights were upgraded during the refurbishment to meet current standards.  The resultBauder systems are only installed by Bauder approved contractors to ensure quality. The installation on this project was expertly carried out by Thameside Roofing Ltd, overseen by Dave Gregory and John White. After sign-off from Bauder site technician, Paul Osbourne, this system was awarded a comprehensive guarantee.  Systems installedBauder Total Roof System (BTRS) with Tapered insulation1 Bauder K5KHeavy duty, torch-applied SBS elastomeric bitumen capping sheet featuring a spunbond polyester reinforcement to allow the finished product to cope with structural movement without fracture, and a mineral finish to provide protection against UV degradation.2 BauderTEC KSA DUO Technically advanced self-adhesive SBS elastomeric bitumen underlayer with “DUO” lap technology to ensure thorough sealing of lap joints, even in lower temperatures. 3 BauderPIR FA G16Tapered PIR Insulation board manufactured in accordance with BS EN 13165 with no facings.

Data Centre’s are one of the many sectors to be seen to utilise the roof spaces. In particular to Data Centre’s; Mechanical and Engineering services are typically installed on rooftops that offer multi-functional elements to the building, making the selection of the roof system more critical. There are a number of factors that are considered when selecting roof waterproofing systems, they should be robust and offer the benefits to future retrofits along with the accessibility for adaptions but most importantly they should be certified to both the Building Standards and the Insurers Requirements.

The Royal Russell School in Croydon demonstrates the vast variety of waterproofing applications with which DANOPOL membranes can be specified. From standard flat roof areas to pitched standing seam roofs, vertical applications and accessible terraces, the flexibility of specification is really showcased on this project. The most noticeable feature is the stunning standing seam roofs, which are also DANOPOL HSF+ membrane, completed with ALPHA PROFILES. These ALPHA PROFILES are raised PVC profiles made from DANOPOL materials which can be retrospectively heat welded to the surface of the completed waterproofing system. The use of Alpha Profiles is rapidly increasing as the design may be highly customised and the installed centres can be changed to suit a clients particular aesthetic preferences and are often installed to obscure any standard membrane overlaps. An advantage of selecting DANOPOL membranes over a traditional metal standing seam roof option is that at less than 3.00kg per m2 for the waterproofing membrane, the system is incredibly lightweight and may be installed onto many lightweight structural substrates. The reduced load, when compared to traditional standing seam roof options, can also translate into savings on the underlying supporting structure. Our DANOPOL+ HSF membrane was also utilised on the terrace areas, which included vertical detailing to clad the internal faces of the parapet walls, providing a fully-encompassing watertight finish to the roof areas. Waterproofing System: DANOPOL+ HSF 1.5mm - Dark GreyConstruction Type: New Build Warm Roof Sector: EducationApprox.

Borrisokane Community CollegeBauder Thermofol PVC single ply waterproofing systemSynopsisOriginally constructed in the 1970s on the site of former workhouses in County Tipperary, the Borrisokane Community College building needed to be demolished and replaced, having exceeded its serviceable life. The client wanted to bring a modern and refreshed appearance to what is a site of great historical significance and the new building’s roof played an integral role in achieving this; with the majority of the roof areas sloping inwards towards the open central courtyard area making them highly visible.Bauder Building BoardProject:Borrisokane Community CollegeLocation:BorrisokaneRoof Area:3,650m²Specifier:Healy & Partners Architects Main Contractor:JJ Rhatigan & Co.Approved Contractor:Priority Roofing & CladdingThe specificationRoof areas totalling over 3,000m2 were fitted with Bauder’s Thermofol single ply fleece backed membrane, which is lightweight, visually appealing and possesses a high tensile strength of ≥ 1100N/50 mm. The system build-up included 160 mm of Bauder’s Thermotech Glass Insulation for superior thermal performance, ensuring the roof achieved the required 0.19 U-Value, and PVC roof profiles were also installed as a cost effective way of replicating the appearance of a standing seam metal roof.

The Little Chapel in Guernsey was built in 1914 and, at only 16 feet by 9 feet, is said to be “one of the smallest functioning chapels in Europe, if not the world”. The chapel and its unique appeal gained national fame after an article accompanied with a colour photograph was published in the Daily Mirror, and it has since been considered one of, if not the most famous tourist attraction in Guernsey.In 2015, work began to weatherproof the intricate building, with the Protec System specified as the best solution for the job.The ChallengeHaving never been finished by its original builder, Brother Déodat, the chapel has been undergoing a long-term restoration project to create a structurally sound building that retains the beauty of the original vision. Firstly, the foundations were underpinned and properly secured for the first time since they were created over 100 years ago. The next priority was to fix the roof, as described by Pat Johnson, chairman of the Little Chapel Foundation:“The asphalt on the roof was hollow and had to be taken off. The concrete underneath was hollow. We ended up with a substrate of soil and clink, so to repair it we had to go inside and grout all the cracks in the ceiling. [The new roof] comprises three layers of concrete, 340 stainless-steel plugs, a stainless-steel mesh and a final coating of concrete”.The task of making the new concrete surface waterproof fell to local Polyroof approved contractor Sarnian Roofing Ltd. Andy Gavey (Company Director) said about the project:“As a boy I would regularly visit The Little Chapel and I’ve always been blown away by its beauty and character. To get the chance to help restore the building to its full potential is a dream come true for me – this has to be my favourite roofing project yet. Polyroof’s contribution towards the roofing works has meant that we were able to provide a top-quality roofing solution that has done justice to the amazing exterior of the building.”The SolutionWith its ability to be applied directly to the concrete to form a lightweight, seamless and durable waterproofing membrane, Polyroof’s Protec System was a clear choice for waterproofing the chapel roof.The first stage was to make the entire roof area fully watertight. Following a coating of primer to seal the porous concrete surface, the first coat of Protec was applied which incorporated fibreglass reinforcement. After 30 minutes the coating had cured and the second coat was applied to the whole roof area. To areas where new mortar was laid to re-embed the pebbles and seashells, which had been painstakingly removed from the old roof, a coating of Polyfinish was applied to provide extra protection.The architect chose a sanded decorative finish to complement the exterior of the building, which is covered in a mosaic made from seashells, pebbles and broken china. To create this finish, a third coat of Protec was applied and, whilst still wet, Quartz Sand was broadcast into the resin. After brushing off the excess sand, the whole roof surface was sealed with an application of Polyfinish Clear.

KAL is a member of the Gowan Group, a family-owned holding company, directly controlling many successful trading companies as well as significant property holdings and financial investments in public and private companies in Ireland, Northern Ireland and the UK.The largest appliance distributors in Ireland, KAL rely on a 30,000 square foot designer showroom for unique kitchen and domestic appliances. Their showroom at Dublin’s Citywest is one of the largest of its kind in Europe showcasing all their kitchen and consumer appliance brands.The ChallengeAfter conducting a survey of the 1,000m2 roof, it was determined that the areas of the roof, specifically the office area, were in need of repair. Some areas of the original roof build-up were starting to leak and lap joints failing due to a poor install.Following the site survey and adhesion tests, a site-specific specification was produced for the client and contractor to overview once all parties were happy with the proposals. With some complex detailing work involved, a decision was made to overlay the existing roof build with Polyroof Protec System.The SolutionPolyroof’s Protec System, a hybrid polymer liquid system with extremely fast curing and installation times, was the chosen system of use for the project. Due to its fully cold-applied application, the works could be carried out during working hours, with little disruption to the office staff below and little working time lost for the client.IPRS Limited, an experienced roofing and panel repair contractor and Polyroof Approved Contractor, were chosen to undertake the work on the project. Firstly, before any work could begin, the original waterproofing of the office roof was pressure-washed and cleaned down. Once all initial preparation was completed, the Protec System application could begin.All areas requiring priming before the main system application were primed and allowed to cure. Any joints were sealed using taping mat and Protec Resin and allowed to cure. Once this preparation had been completed the main Polyroof Protec System, chosen in light grey by the client, was applied.The first coat was allowed to cure before the final coat was applied. Due the Protec System Rapid Cure technology, the finished roof could be walked on after just 30-60 minutes after applications. This allowed for large roof areas to be made fully waterproof within a matter of hours. After the inspection was completed, the client received Polyroof’s trusted Accredited System Guarantee.Taking away the challenges of flat roofing projects.Polyroof’s reputation has been built on the high level of technical support provided to clients before, during and after every contract. We like to work closely with our clients from the very beginning of a flat roofing project right through to completion and throughout the lifespan of the roof. From our experience, this is the best way to guarantee that all aspects of the roof are finished to the superior standards that our clients expect.

Project DescriptionThe new £180M RHSC facility has 1,800 rooms over 50,000m² in a modern and high-quality setting at Little France, Edinburgh. The five-storey building, has a large atrium with a shop and cafe, a stunning skylight linking both hospital entrances, a helipad on the roof and a link building adjoining adult and paediatric emergency departments.Specific Project ChallengesThe single largest ever BIM project undertaken by HLM ArchitectsA roof of highest quality to ensure best environment for patientsThe first acute hospital facility to be procured under the Scottish Government’s Non Profit Distributing Model (NPD)Solutions OfferedThe standing seam system incorporated a series of tapered and straight sheets to ensure that the curved roof plan was achieved without the need for junctions, as well as providing the platform for a vast array of photovoltaics, and a permanent roof access walkway.Ash & Lacy also supplied support in the form of site inspections throughout the construction process, design for roof tapers and all perimeter and feature fabrications and fasteners.

For the redevelopment of a former builder’s yard in Greenwich into a new build block of live-work units and residential flats, the developers were looking for a roof system which would offer long term waterproofing integrity, exceptional green credentials and enhanced aesthetics. The proposed green roof system would also reduce water run-off, create a wildlife habitat and help towards securing Code for Sustainable Homes Level 4.With a waterproofing system required to protect the concrete deck above the flats, a selection of cold-applied products were provided by Proteus Waterproofing that met the client’s requirements. The specialist contractor worked with Proteus Waterproofing on a specification which included the Cold Melt® inverted waterproofing system, Proteus Pro-Therm XPS and finished with a Proteus Pro-Living® green roof.Fast, hassle-free application The 500m2 Cold Melt® insulated Pro-Living® roof system was selected by the client and contractor for its ease of installation, cold application and all-round green credentials. After the pre-cast concrete roofing panels were craned into position, the joints were made good ready to accept the Cold Melt® inverted roofing waterproofing system. The inverted roof system incorporated Cold Melt® and Proteus Pro Therm XPS 150mm insulation. A Proteus Low-K Membrane was then applied prior to the application of the Pro-Living® green roof to complete the system build-up.Quality control Proteus Waterproofing worked in close partnership with the Contractor to successfully deliver the project to a very high standard within the required timeframe.Long term performance Incorporating recycled rubber-crumb and other organically grown products, Cold Melt® creates an elastomeric, seamless, cold-applied membrane and can outlast the lifetime of the substrate on which it is installed.

A complete roof refurbishment, including thermal upgrade and full waterproofing of a church centre.Systems in useEcoflex®The project included various roof areas with different systems in situ, all requiring thermal upgrade, and increased falls to remove standing water from the roof. There were also rooflights and roof lanterns that needed to either be replaced or removed and boarded over, a live gas pipe which required lifting to accommodate the new roofing system, and various redundant SVP’s and chimneys.ChallengesThree separate roof areas required upgrading as the existing waterproofing was failing and reaching the end of its service life. Water ingress was occurring, causing damage to the internals of the building.Axter carried out in depth surveys and took various core samples to determine the existing build ups of each roof area. It was identified that remedial works were needed to stop water ingress, thermally upgrade the roof, remove standing water, and remove certain rooflights. Two out of the three areas had redundant and dated rooflights / roof lanterns. There was also an active gas pipe laid across the main roof area which had to be taken into consideration when specifying works.SolutionsThe 3 existing roof build ups included Asphalt with RBM cap sheet and stone chippings, Asphalt with RBM cap sheet and solar reflective paint and finally an EPDM system. Our core samples revealed that the areas with existing asphalt were in good condition. Therefore, Axter advised to only remove the solar reflective paint and the stone chippings to avoid the asphalt from going into landfill and to keep costs down. We used a mixture of torch applied and self-adhered AVCL’s, dependant on the deck type and to comply with SAFE2TORCH areas. Axter’s Ecoflex® ADH single ply membrane was the system of choice as this kept the use of naked flames to a minimum as the building remained in use throughout the refurbishment programme. The system provided a 20 Year Guarantee covering design, materials and workmanship and achieves Broof(T4) fire certification.A live gas pipe was running across the main roof area. It was decided with the client that this would be replaced and raised to accommodate the new roofing system.As this was a live site, the safety of the client and their visitors was a risk that needed to be considered. Risk and method statements were developed and written with the client’s ongoing activities in mind. The contract was carried out without the occurrence of any accidents or incidents.AcknowledgmentsWe were delighted to have Axter and the Nautilus work on our roofing project and again were delighted with the outcomes. From initial consultations with both Nautilus and Axter we found them to be highly knowledgeable and professional in providing solutions and specifications. Axter’s attention to detail manifested through their survey work and their recommendations provided us with a great deal of assurance in the project, along with ongoing technical assistance from the Axter team to provide reassurance at different junctions in the project. Nautilus were extremely professional in their approach and a pleasure to have on site. Their high regard for health and safety and CDM on site was also evident and ensured a safe environment for all stakeholders. The project was completed by Nautilus in a timely manner and certified by Axter, giving us high confidence in the completed works. A real pleasure to work with on all sides.Andy Lee , Vine Christian Centre

Situated in the picturesque village of Tintern in Monmouthshire, the Cistercian abbey is one of the most historic monastic ruins in Wales. In 2013 work started at the abbey to replace the roof of the gift shop, which had exceeded its serviceable life. The brief for this project was to not only repair the failing roof, but to bring the abbey to the forefront of modern-day roofing technology with the installation of a state-of-the-art photovoltaic (PV) system. Given these requirements, BauderSOLAR’s innovative PV solution, SOLfixx Plus, was a natural choice.

Bilco UK has supplied an innovative replacement roof hatch for a medieval church in Norfolk. St Mary’s is one of the 653 churches within the Diocese of Norwich. When it came to providing a means of safe access to the roof area a product was required that was both technically and architecturally suitable. Medieval Masonry Ltd, a specialist contractor in the restoration and conservation of historic buildings with over 50 years of experience in the industry, installed Bilco UK’s S-50VMTB VersaMount® Replacement Roof Hatch.

The roof area was badly damaged by heavy storms, with all existing ballasted solar panels lifting off the single ply roof and destroyed beyond repair. The client needed the remedial work completed to fixed deadlines in order to comply with insurance requirements, and wanted to optimise the roof by replacing the pre-existing photovoltaic (PV) array with a solar solution that would deliver superior energy generation. The office also had to remain operational throughout the works, creating logistical challenges

Fairford School was refurbished in 2008 and required a roofing system that could offer unsurpassed durability complimenting the honey coloured brick walls.Metrotile’s .900mm Slate profile in Bronze was specified, as it is the only system that could meet all of the project’s demands. The school’s new Metrotile Slate roof delivered on all counts including performance, durability, low whole-life cost and aesthetics. As Fairford is situated in a rural setting, the aesthetics of the building’s roof needed to compliment the natural surroundings.

The National Gallery and the Science Museum - two of London’s major and iconic visitor attractions built more than 150 years ago – required an extensive programme of roof upgrades and maintenance. Working with the National Gallery since 1995, the roof replacement and thermal upgrading project has seen in excess of 12,000sq m of Sika Sarnafil membranes installed, together with insulation, roof lights and walkways in a series of over 30 completed projects – including the complete Sainsbury Wing in 2008.

Roofing slates from Welsh Slate's Cwt-y-Bugail quarry were specified for the new-look Royal Pagoda. Welsh Slate roofing slates have played a “critical” role in the award-winning renovation of one of London’s most unusual buildings. A two-year conservation project to restore the roofs, and 80 decorative dragons, on the 18th Century Great Pagoda in the World Heritage Site of the Royal Botanic Gardens at Kew will give the public access to the upper floors for the first time in decades.

Gary Lambert of Broadstairs-based Complete Roofing chose Rhepanol fk single ply membrane to waterproof the 690 m2 two-tier curved roof of celebrity restaurant Rock Salt, which overlooks Folkestone harbour.

Our purposeAs one of the UK’s leading housing associations, the Guinness Partnership prides itself on providing high quality homes that meet or exceed current Standards. It is therefore committed to a continuous programme of maintenance and asset management across its 60,000 homes estate.As part of that process, the 13-storey 1980s-built Waverley Court in Crewe was due for refurbishment, including new windows and heating for the 95 flats therein. An initial survey highlighted that the 1200m2 roof was failing and in need of upgrade to maintain its weathertightness.Our in-depth roof report also identified that the insulation was below current standards. Safety on the roof for maintenance was also an issue: the existing handrail was originally erected as a temporary fixture, penetrating the waterproofing and providing inadequate rooftop security for working at height.Our solutionThe existing waterproofing had perished beyond useability. We advised complete strip of the existing back to the concrete deck, and building up a new thermally-efficient roof to meet current standards required under the Part L of current Building Regulations.Our TA-25 W Flat Roofing System for warm roofs was installed by Approved Contractor Everlast as sub-contractor to the principle contractor, Wates. To address the poor falls on the roof, the insulation was tapered to the perimeter. We achieved an overall roof U value of 0.17W/m2K, exceeding the current Regulatory requirement of 0.18W/m2K. In line with Safe2Torch guidelines, our self-adhesive system was used to detail around roof penetrations for extractor fans and similar plant.We highlighted and designed bridging details to maintain the fire integrity around compartment walls to comply with Part B3 of Building Regulations.We designed a new, permanent and safe handrail system. This is fixed to the brick façade of Waverley Court, avoiding any penetration of the roof fabric and thus maintaining its integrity and watertightness, whilst minimising maintenance requirements.“Langley’s expertise and attention to detail has enabled us to deliver on our ambition of providing homes that people want to live in. Langley’s performance has helped us provide a dry, warm, safe living environment that exceeds current Regulatory requirement. The independent insurance-backed guarantee covering design, materials and workmanship adds value to our long-term estate asset management.”

Formerly the home of AstraZeneca, Alderley Park is a world-leading life science and innovation campus situated across 93,000 sqm on the outskirts of Manchester city centre. With a mix of new-build waterproofing requirements and existing roof refurbishments, the client appointed Garland UK as a roofing partner across the multi-building site. Alongside the refurbishment and new-build site works, Garland UK was also briefed to provide a tailored design specification for the Glasshouse Project, which would become the largest triple pitched standing seam roof in the UK.Garland UK's 3 system portfolio of high-quality bituminous membranes, cold applied liquid coatings and profiled metal ensured that each roof would get the right system for its unique challenge.

Low environmental impact... CHALLENGE All over the world architects and building owners are trying to create buildings with a low environmental impact. For this private house, the architect wanted to combine an aesthetical finish of a metal roof in combination with PV and hot water panels. The biggest issue for the architect was the fixing of these panels without having leak problems in the future. SOLUTION The roof was waterproofed using a RENOLIT ALKORPLAN roofing membrane that is mechanically fastened onto the supporting roof structure. Two kinds of PVC profiles were heat welded onto the waterproofing membrane: on the one hand RENOLIT ALKORDESIGN profiles (for aesthetical value only), on the other hand there are RENOLIT ALKORSOLAR profiles, which function as the base to attach the hot water and the PV panels. The gable was also finished with the RENOLIT ALKORDESIGN system.

The post-industrial area of Hackney Wick has, in recent years, undergone large-scale regeneration.Sitting on the site of a dilapidated Wallis Road factory and yard space, this mixed-use development with 44 luxury loft apartments and 2000 sqm of commercial workspace retains the character of the area.SystemQuadro porcelain paving tiles in the shade ‘Crema’ were used across each of the private balconies, as well as on the roof terrace.Tiles were supported by various RYNO height-adjustable pedestals.Ease of InstallOn roof terrace areas, RynoPaveSupport RPF Adjustable Paving Pedestals were used to support porcelain tiles.RPF Pedestals raise the tiles off the roof, allowing for fast drainage and maintenance access when required. They have a large supporting base, which protects the roofing membrane.

UNIZO office building CHALLENGE Dedalus Architects specified zinc for waterproofing the timber frame UNIZO office building in Eeklo. Not only for the roof, but also for the facade and bottom side of a unique construction detail. To be precise, waterproofing horizontally, vertically and even upside down! To entirely cover the structure however, appeared not to be possible when using zinc. If you opt to use this traditional waterproofing material a ventilated air space must be provided underneath the zinc covering. This of course entails an opening for ventilation purposes underneath the roof edge, if not, condensation will occur. In the case of a building where the facade has to connect seamlessly with the roof and the underside, leaving an opening is not a possibility. So, despite the attractive appearance of zinc, a waterproofing solution with this material was not an option. SOLUTION Thanks to their collaboration with roofer ALBITUM and previous experiences with RENOLIT roofing products, Dedalus Architects came up with a nice alternative: RENOLIT ALKORDESIGN standing seam imitation. A perfect solution for a difficult challenge. No ventilation needed, no connection problems, the same looks as a zinc roof and, above all, more cost effective! 

The Housing Trust’s first encounter with Metrotile Lightweight Steel Roof Systems was during a refurbishment project at Pendle House, Denton. A home for the elderly, the building needed a new roof but couldn’t accommodate traditional products due to large spans between the trusses and the need for reduced weight on the supporting structure. Metrotile was chosen due to the lightweight and eight-pan profile design. It was after this project that the many benefits of Metrotile Lightweight Steel Roofing became apparent to New Charter Housing Trust and more projects swiftly followed

The area of Bermondsey Spa in South London was a vast development project in 2017 and 2018, the Bermondsey Square Hotel being a focal point of the area. As well as assisting with various applications for the projects, Fixfast helped with site visits and rainwater calculations to ascertain the needed level of roof drainage. Having swiftly answered these requirements, Fixfast then supplied many of the well proven FarBo roof outlets together with leaf guards to ensure the longevity of the roof areas."Brilliant service, didn't have any problems at all"Tanya Hall - Buyer

The Joseph Black Building, found in the King’s Buildings Campus at the University of Edinburgh, houses the School of Chemistry and is one of the oldest buildings on the campus. But its existing copper roof covering had come to the end of its natural life. Sika Sarnafil’s flagship Sarnafil Plus refurbishment offer was the perfect solution for this project. Sika Sarnafil Membrane S327-15EL in Patina Green was chosen to replace the old roof covering, as the local authority planning department advised that this product was an acceptable replacement for the original copper roofs on the listed building.

Financed by county council capital funds, Northamptonshire County Council undertook a multi-million pound remedial works programme on a number of schools originally built in the 1960’s and 1970’s. All of the buildings were suffering from some degree of water ingress, and the roofs needed to be brought in line with current building regulations for improved thermal performance. Sika Sarnafil’s specialist roofing contractors installed over 50,000m2 in light and lead grey of G410-18EL single ply membrane to the school roofs.

100m2 flat roof on top of a school in was going to become an outside classroom. Access was severely restricted so it was not possible to consider traditional decking boards. Work was required at half term. Ipe timber decking tiles mounted onto adjustable pedestals were selected. The pedestals were delivered in boxes and the 500 x 500mm Ipe timber tiles could be carried by hand up all the flights of stairs to the roof area. The fall was accommodated with the adjustable pedestals and the hardwood decking was flat and durable. The roof was completed in three days.
