"roofing"

Established in 1976, Corfe Hills School in Dorset welcomes over 800 secondary and sixth form students through their gates each year. Since achieving Academy status in 2011, Corfe Hills have been looking ahead, keen to develop a schedule of works for building improvements that support the school’s growth and ultimately safeguard the building’s future.Over time, the existing roofs across the site had experienced continuous water ingress issues that needed to be addressed. Multiple roof penetrations from the roof lights were leaking water; the existing waterproofing system and the overlaid bituminous membrane were failing in places resulting in splits and blistering, and the metal roof had rusted beyond repair. With rain seeping directly into the classrooms below, action had to be taken to ensure the site was remedied to a safe and comfortable learning environment for students and staff.Garland Technical Manager, Paul Boole, was instructed by building surveying firm Kendall Kingscott to support Corfe Hills approaching CIF bid for the critical roof refurbishment works. An essential part of the brief was to ensure that the buildings were not only fully waterproofed but to upgrade the overall thermal efficiency, alongside securing a robust 20-year guarantee.In support of the CIF bid, Paul carried out a thorough investigation of the school’s roof assets for Kendall Kingscott, producing core sampling data, detailed condition surveys and U-Value calculations to outline a clear specification for the works required. 

A high profile 0.7 hectare residential development, completed in 2017. This project featured the Aquamodul warm blue roof, one of the largest schemes of its kind ever achieved within the capital.ChallengesThe project presented significant challenges, such as demanding thermal performance criteria combined with a challenging planning requirement to achieve maximum outflow rain water run off rates of 10l/s across the entire 7500m2 site.SolutionsThe design and implementation of a site wide blue roof ensures the development’s contribution to mitigating flood risk in London and supports the protection of England’s waterways. Modelled over a 300 year period, the blue roof design is future proofed in terms of its provision for likely climate change and increases in predicted peak rainfall events.Second generation hot melt structural waterproofing system, Wilotekt-Plus, was installed as the Air and Vapour Control Layer (AVCL), which provided an extremely robust waterproof structure during the external envelope and superstructure construction phase. Hytherm ADH thermal insulation and BBA accredited Force Dalle bitumen membranes with anti-root technology where later installed to complete the waterproofing and insulation system.Prior to hand over and installation of the Aquamodul blue roof attenuation cell, the waterproofing system was integrity tested using a differential pressure testing method by independent specialists to ensure the roof was watertight. Once passed as secure, the Aquamodul blue roof cassette and biodiverse (brown) living roof finishes where installed with the further addition of a PV panel array generating the majority of the building’s electrical energy requirements.Systems in useForce Dalle®Wilotekt®-PlusAquamodul®

Challenge Modern paving flags required for city centre roof terrace at flexible workspace Urban HQ situated in Eagle Star House offers state-of-the-art facilities including meeting rooms, event space, a member’s lounge and bar.  One of its most notable spaces is the rooftop terrace. The roof garden provides co-workers with a valuable communal area to foster company culture or escape from their desk. The terrace offers a flexible space to relax, socialise or entertain while taking in the views of Belfast city and beyond. The central design aspiration was to bring a New York or London feel to Belfast city. It was essential that the roof terrace hard landscaping aligned with the design ethos. SolutionContemporary Mayfair Flags installed on pedestals were the perfect choice  Tobermore’s Mayfair Flags with their granite aggregate contemporary finish were the perfect choice for Eagle Star House. A contrasting finish was created on the terrace in the colours Silver and Graphite. A simple yet effective stacked laying pattern was deployed which adds to the clean look of the contemporary roof terrace. The commercial space has more of a boutique hotel feel than a city centre office. The Mayfair paving flags were installed onto adjustable pedestals, creating a level surface throughout the terrace. The use of this installation system enables the laying of paving flags without the need for grout, sand or adhesive. It also creates a void beneath the paved surface allowing an easy and convenient route for exterior cables or other services. View our Roof Terrace Support for installation on pedestals for roof terraces, balconies and roof gardens.

Heavy 3 slate has been used to rebuild a previously run-down village hall, into An Talla Loch Ness Visitor Centre, a visitor gateway to Loch Ness and the Caledonian Canal. The renovation project used Heavy 3 spanish slate for its similarities, aesthetically and characteristically, to the traditional Scottish Ballachulish.  Part of a £2.5 million project, the developers Loch Ness by Jacobite took over the building with the view of creating a base for visitors to embark on a journey along the loch. The extensive renovation of the Victorian-built Dochgarroch Village Hall has been re-named An Talla, meaning ‘The Hall’ in Gaelic. It now comprises of a reception, retail outlet and café, all built around a new central courtyard and external terrace overlooking the Caledonian Canal towpath and quayside. As the original slate used on the building was Scottish Ballachulish, Heavy 3 was selected for its shared characteristics such as its blue-black colour and thickness. Heavy 3 slate is the best choice for repair and replacement of traditional roofs in Scotland as it produced at an extra thickness, 7 - 8mm, meaning it is ideal for combatting Scotland’s inclement weather.  “As the Loch Ness centre is an extension of the original hall building which has a traditional Ballachulish roof, Heavy 3 slate was selected as the ideal match to maintain the aesthetic,” commented Ian Sharpe, roofing installer at Wyvis Roofing – contractor on the development.  “I specify Heavy 3 for many of my roofing projects as the likeness to traditional Scottish slate is unmatched by anything else on the market. As always, the installation went really well and the CUPA PIZARRAS team – who I use regularly for roofing projects - were on hand to assist if needed.“One particular quirk of this project was the family of bats that had taken residence in the roof of the building. As bats are a classed as a European protected species, it is illegal to remove them; so, we installed a number of lead bat vents, allowing the bats to fly in and out of the roof space freely – yet more wildlife for visitors to observe.” 

About the projectIn the summer of 2016, Paterson Gordon Architecture were approached to renovate an existing steading that stood in a derelict state. However, the stunning views of Loch Lomond created an inspiring opportunity to design and build a modern family home.Which FAKRO products were used?This property required an increase of natural light for a dark space within the building which could not fulfil its highest potential. By specifying DMF-D U6 and DXF-D U6 flat roof windows, Paterson Gordon Architecture was able to deliver a substantial proportion of natural light into the central hallway. DMF - D U6 Manually-operated Flat Roof WindowManual opening flat roof windows.The type F window is equipped with an energy-efficient triple-glazed DU6 glazing unit.The external glass is 6mm toughened while the internal glass is laminated and anti-burglary P2A Class.Heat transmittance co-efficient for the whole window is U-Value 0.88W/m²K.

To meet this requirement, FAKRO conservation windows were specified and installed. The characteristic feature is a black vertical mullion bar down the middle of the window and its black cladding. Making it suitable for traditional construction. Most of FAKROs standard windows are available as a conservation window.Why were FAKRO products specified?Primarily, the appearance of the flat roof windows was behind the reason for choosing FAKRO, along with the diverse product range and the ability to install the windows onto zinc, slate, and single-ply membrane roofs.

Modern materials were employed in the quest to recreate part of Bristol’s heritage. SIG Design & Technology supplied IKO’s Armourplan PSG single ply membrane because it fitted the bill perfectly as the roof covering was ideal for replicating the original seamed lead roof.

Set within the Garscbue Estate, Archial Group, the Architect, wanted a new build project with as minimal visual impact as possible, so the building was constructed within the side of a hill with a green roof. Towards the end of the roof’s construction a seeded grass finish was opted for.

BriefAs part of the drive to revitalise Kirkby Town Centre, the local authority, Knowsley Metropolitan Borough Council, has been significantly investing in regeneration works. A redundant B&M shopping centre formed an important part of the uplift.At 36,000 sq ft, the empty precinct was the largest vacant unit in the town centre and was in need of significant repair and modernisation. Bringing the building up to date was crucial in encouraging businesses back to the area and delivering more choice of retail outlets to visitors.The project was estimated to cost £1.66million, with £450,000 allocated to the roof renovation, which was to be carried out by Paramount Roofing Systems, in association with IKO.ChallengesThe busy, central location of the shopping centre presented several challenges for the roof installation. The existing roof needed a comprehensive refurbishment, including stripping back to the metal decking and removal of all layers and outdated materials.A total of 48 redundant skylights needed to be carefully and meticulously taken out as they were no longer needed or functional. Any obsolete ventilation fans and plant equipment also had to be removed, as streamlining roof space was essential for efficiency. This all had to take place before the installation commenced.When it came to delivery of materials, there was limited laydown due to the surrounding live loading bays for neighbouring shops and this lack of space also affected the storage of the materials on-site.Inclement weather presented a significant challenge for the team. Despite operations taking place during the summer, torrential downpours were frequent. Protecting the integrity of the building was paramount to ensure the businesses below the installation could continue trading without risk of water ingress or leaks.SolutionAs this was such an expansive project, it was important that the roofing system was robust, easy to install and would stand the test of time. IKO worked with Paramount Roofing Systems to ensure the most suitable solution was specified for the replacement roof.A fully built-up bituminous felt warm roof was chosen as the best option, as it was designed to ensure effective insulation, weatherproofing and longevity for many years to come.To mitigate disruption to nearby trade, Paramount Roofing Systems effectively coordinated with local businesses for the duration of the project. The team established a robust schedule, so that construction activity was minimally affected by the town centre’s busy hours and zoned time restrictions.A telescopic forklift truck was hired specifically for the project, to handle offloading and loading more efficiently and allow the team to move more precisely within the confined space. Four operatives were trained to ensure that the forklift truck was used safely, which was imperative given the high footfall close to the site.IKO arranged for bulk materials to be delivered directly to the roof to help overcome the issue of restricted space. Materials were also stored off-ground and covered at all times with strategically placed tarpaulins to avoid water damage from the persistent rain.Despite the wet weather conditions hindering progress, the project was delivered just over the expected time frame of 8-10 weeks. The collaboration between IKO and Paramount Roofing Systems was pivotal in ensuring that the project met and exceeded requirements – contributing to an integral building that promises to give a much-needed boost to Kirkby town centre.

Teesside University’s Greig Building, named in honour of the founding father of computer science Bill Greig, is the home of the university’s Computer and Mathematical Sciences Studies department. When the aged bituminous roof coverings had shown failures including splits, blow holes and crazing, it was of paramount importance that a waterproofing solution could be provided as quickly as possible to prevent the risk of water damage and disruption.The university’s site maintenance team turned to Polyroof for a solution, which started with a detailed survey of the three roof areas totalling 750m2.The ChallengeCore tests taken at appropriate locations throughout the roof areas demonstrated that the existing warm roof build-ups were free from signs of decay. This meant that the roofs could be retained and over-coated with a new waterproofing system allowing for a rapid, minimal-disruption solution.A bespoke specification was put together based on the findings from the Polyroof Survey Report that provided a comprehensive set of recommendations, including remedial instruction for many problematic roof details. With the peace of mind and satisfaction that the various problems on the roof would be solved through Polyroof’s proposals, the client progressed with a tender process that resulted in a successful application by Polyroof Approved Contractor BBR Roofing Ltd.The SolutionPolyroof’s Protec System, a hybrid polymer liquid system with extremely fast curing and installation times was chosen as the ideal solution for the project. Due to its fully cold-applied application, the works could be carried out during the university’s term times, without having to wait for closure periods between semesters.Works began with the existing asphalt and felt coverings being made good where required, including the levelling and filling of blow holes and cracks with Polyroof Structural Repair Mortar. Next, the surfaces were thoroughly cleaned and degreased to provide a sound substrate for the new waterproofing system.Many of the roof perimeters and junctions featured parapet walls which were identified as a potential point of water ingress during the survey. The inner faces and tops were therefore boarded-over with 18mm Polyroof approved plywood which would allow these details to be fully encapsulated with the Protec System, meaning their waterproof integrity would be covered under the new system’s guarantee. Protec can waterproof vertical areas with the greatest of ease due to its thixotropic formulation, which means slumping and running is minimised during application.Polyroof’s extra-tough GRP trims were then installed to create neat and robust edge detailing for exposed perimeters before the main Protec system application commenced. After priming surfaces where required, the first coat of Protec was applied and reinforced with PolyMat 450. With its RapidCure technology, the Protec can be walked on and over-coated after only 30-60 minute after applications, meaning large roof areas can be made fully waterproofed within a matter of hours.After the second coat of Protec was applied to complete the waterproofing system, designated maintenance walkways were formed through embedding quartz sand aggregate into a third coat of Protec liquid.Completion and InspectionThe refurbishment of the roof was completed within the client’s target timeframe and budget. Following a final inspection by Polyroof Technical Services, which highlighted quality workmanship of BBR Roofing, the client received Polyroof’s trusted Accredited System Guarantee and now has the peace of mind the roof will be leak-free for decades to come.

The project consisted of two similar flat roof areas totalling 1,100m2 above high-rise residential blocks in a city centre location. The existing roofs were an inverted roof design that had been waterproofed with single-ply that had failed prematurely. Numerous short-term, localised repairs had failed to stop the water ingress and leaks had been a long-term problem.It would have been impractical to remove the tons and tons of ballast and insulation from the top of the high-rise building and it was imperative to the client that removal or replacement works were not involved at all. The specific nature of this project required careful consideration, and so a survey of the roof was arranged.The SolutionA report from an independent consultant commissioned by the client identified a problematic challenge with an overlay option. The existing falls of the roof were assessed to be poor, and so standing water would be an issue for any new waterproof covering. The report concluded that this would reduce the lifespan of an overlay waterproofing system and so was advised against. The client initially thought this to be a stumbling block and that costly and impractical modifications to the roof would need to be made.Having worked with Polyroof on scores of other projects, the client turned to Polyroof Technical Services for a solution that could meet their stringent criteria. Following on from the preliminary discussions, Polyroof’s Technical Services assessed the site, taking core samples and then providing a suitable specification to overlay the roof with the Protec System.The BBA certification of the Protec system specifically covers use for zero falls (completely flat) applications, meaning the client had absolute peace of mind that standing water would not be a detriment to the integrity of the waterproofing system. The client was able to achieve the original objective of an overlay system and benefited from the associated cost and time savings. Furthermore, the BBA certificate states that when used in inverted roof scenarios the lifespan of the Protec system is as long as the design life of the roof.Work was started with J R Flat Roofing, a Polyroof approved contractor with national coverage, moving the ballast and insulation to one-side in four phases of 140m2 at a time, exposing the single-ply membrane to which the Protec system was directly applied.Due to Protec’s rapid cure and walk-on times (30-60 mins dependent on conditions), the system is ideal for larger, phased refurbishment, as specific sections of the roof can be made waterproof with the full Protec system in one day. When carrying out the next section, the new Protec membrane forms a totally seamless and watertight joint to the existing Protec-covered areas.Another objective was to reuse the original inverted insulation and ballast pebbles as this was cost saving and negated the need for the lifting logistics that would have been involved in bringing the ballast to ground level. Additionally, it made the process as environmentally compliant as possible by keeping waste to a minimum. The insulation and pebbles were re-applied in its original format and, due to the weight of the pebbles, was a mammoth task that required three miniveyors to help with the handling. A series of special aluminium breather vents were also fitted down to the concrete slab roof substrate to enable the surface to dry out over a period of 12 months.The whole job was completed in three weeks and the client was delighted with the finished work. With a 20-year insurance back-guarantee and a maintenance-free waterproof membrane that will last as long as the roof stands, the client was once again left with total peace of mind that their buildings could not be better protected.

IKO Polymeric, SIG Design & Technology, and Excel Roofing Services have collaborated to design, supply and install 250m2 of single ply roofing for the new kiosk, glass covered beach walkways and stores which houses the latest Oceanarium residents, ten Humboldt Penguins.

The Garscube is described as an ‘urban barn’; with a low slung fibre cement slate pitched roof intended to be sympathetic to the character of neighbouring properties. The building sports a single homogenous fibre cement slate skin to form both walls and roof alongside generous window openings.

The roof space to an existing commercial property in the North-West of England has been given the added protection of having its very large roof-space sub-divided using the APOLLO Lite™ 30:30 system manufactured by TBA FIREFLY™.

The Olympic Stadium’s transformation into a multi-use stadium has seen the specification of Marlon CS polycarbonate rooflights. The 44,000m² roof is the largest cantilevered roof worldwide and includes 4,484 polycarbonate sheets. The project was a feat of production and delivery logistics with each sheet cut to size forming 2,756 unique shapes and labelled with a unique placement code to ease installation. With the stadium width 84 metres at its deepest, the transparent roof covers all 54,000 spectator seats protecting fans from the elements as well as ensuring optimum grass growth for pitch perfect conditions.

The original waterproofing on the Maternity Hospital roof had exceeded its serviceable life and begun experiencing water ingress, requiring urgent remedial work. Bristol City Council wanted to optimise the roof area by installing a high quality, long lasting PV array that would contribute to its Solar City scheme that aims to provide one gigawatt of solar power to Bristol by 2020. The installation needed to cause minimal disruption to ongoing work at the hospital and insulation upgrades were necessary to ensure the roof achieved the required 0.25 U-Value.

Celebrating its 50th anniversary in 2019, the iconic Bell’s Sports Centre in Perth, needed a new roof to protect the building. With the previous roof membrane nearing 30 years old the centre needed a long-term and robust roofing solution. The product of choice was the mechanically fixed Sarnafil S327-15 EL Light Grey as it is more than able to cope with all the extremes of the Scottish weather and has been certified by the BBA to last in excess of 40 years. The durability of the single ply material ensured a long-lasting solution for the project.

Over 10,000 square metres of the Thermo Ash 'hidden-fix' system were supplied for various external areas on the Turbine Halls of the iconic Battersea Power Station including the private roof terraces and balconies of the sky villas on the roof of the building, and roof terraces of the commercial office spaces.The use of the Grad system not only created stunning areas, but contributed to significant savings on the labour cost of installation.The installation of Thermo Ash used Grad aluminium rails with factory-placed clips for perfect alignment, placed on Buzon UK's PB range of pedestals where required.  

As part of the refit, the building required a new roof as it was showing signs of wear and had started to leak. As well as a waterproofing solution, the client wanted to improve the thermal performance in line with current building regulations. For health and safety reasons, the client also requested a flame free roofing solution.

Profile 6 fibre cement roofing sheets were used on Cefnamlwch Farm to keep condensation levels to a minimum. The farm is also subjected to strong coastal winds, so the hardwearing, durable sheets made them an ideal choice from which to construct the new build’s roof.

Herefordshire Housing Association, announced plans of a five year project with the aim of improving the energy efficiency levels of its entire housing stock, which includes over 500 Cornish type houses across Herefordshire. Many of these homes were built between 1946 and the 1960’s as a ‘temporary’ solution to the post-war housing crisis and they are easily recognised because of their distinctive Mansard roof structure.The contractors, Merriman Roofing and distributor Encon Insulation were given the target of improving the thermal performance of this insulation in the Mansard roofs to a u-value of 0.30 W/m²K, while minimising the disruption to residents which wouldn’t have been possible using traditional means. Because the houses were occupied, all improvement works needed to be carried out from the outside to minimise the impact on the occupants. Unfortunately, due to the Mansard roof which covers the second storey of the building, it’s difficult to significantly improve the energy efficiency of the homes using traditional materials and tools, with a u-value target of 0.30 W/m2.K, traditional insulation was too thick. In the past, efforts to improve the insulation of the Cornish-type homes have been limited by the design of the roof. Achieving a good fit within the timber frame using externally applied options has proved to be challenging due to the narrow cavity between the interior wall and the exterior roof and applying products from inside can typically be disruptive and intrusive for occupants.After visiting the houses that required new insulation, our experts came to the conclusion that our SuperFOIL SF40 multifoil insulation would be the perfect solution to the problem. Because SF40 measures to be just 65mm thick when installed, it was a suitable fit for the unusual Cornish-type properties and their distinctive roofs which only allow a narrow space for insulation. Working with, Herefordshire Housing, Encon and Merriman Roofing Contractors Ltd, we have supplied enough insulation to provide for over 500 houses, improving heat retention in the winter and energy efficiency throughout the year. SuperFOIL worked very closely with Hereford Housing Ltd and Merriman Roofing Contractors Ltd to offer a bespoke solution. SF40 was up to the challenge achieving 0.26 W/m2.K, significantly exceeding their target value. A single layer of SF40 provided maximum performance, minimal thickness, improved air-tightness, radiant barrier, huge cost savings and less disruption to the residents.

Cygnet Hospital, a new state of the art medical campus based in Maidstone required a waterproofing membrane for the newly installed concrete and metal decks. Proteus Waterproofing applied their Cold Melt® membrane, to provide a seamless leak protection to the inverted roof, that was then finished with Proteus Waterproofing’s Pro-Living® Green Roof. High Performance WaterproofingFirstly, the metal deck for the main roof was prepared and overlaid with Pro-Vapour Control SA, a self-adhesive bituminous waterproofing membrane that forms a barrier against vapour and gases, ready for the Proteus Pro-Therm PIR Insulation and Cold Melt® waterproofing installations.Proteus Pro-Therm PIR is stable, rot proof and will remain effective as an insulation system for the lifetime of the waterproofing covering, making it suitable for new builds. Cold Melt® waterproofing was then overlaid to the main roof and upstands. The exposed areas were covered with Cold Melt® UV Top Coat, making the waterproofing UV stable. Cold Melt® provides a seamless leak protection and is cold applied, therefore removing the risk of fire. The roof was completed with a Pro-Living® Green Roof providing ecological benefits for the building. Health and SafetyWhen working on occupied buildings, safety is of utmost importance. Proteus Waterproofing’s Cold Melt® system is cold applied and low odour, therefore meeting all necessary health and safety requirements. Cold Melt® is quick, simple and safe to apply allowing the Proteus Approved Contractor to successfully complete the project to a high standard within a short time frame, whilst ensuring the planned building works continued to run on schedule.Long Term PerformanceIncorporating recycled rubber crumb and organically grown products, Cold Melt® creates an elastomeric, seamless, cold applied waterproofing membrane. Cold Melt® system can include inverted roof insulation and, with or without insulation, can be designed as a paved, ballasted, green or brown roof. The membrane is made in the UK, does not become brittle with age and is BBA Certified to last the life of the structure.

We were brought in by Middlesbrough Council to complete the roof refurbishment of Abingdon Primary School.Systems in useExcel®Starcoat® ROverviewWe had originally worked with Middlesbrough Council to complete Abingdon Primary School’s first phase of the roofing in 2015, and were asked to review the remaining flat roof areas to bring them in line with the previous phase.ChallengesWith this being a school, all works had to happen outside of school terms, so works began at the beginning of the summer holidays and had to be completed before the start of the September term. This on its own posed challenges to make sure that all roofing works were completed on time so as not to disrupt any of the children’s educations. Logistics were crucial, as was collaboration between Axter, NT Sweeting and Middlesbrough Council.There was also the issue of combustible areas around the perimeter of the building with some cladding details and some windows that could not be detailed in a traditional torch on application.SolutionsWorking closely with Middlesbrough Council from the outset, we surveyed the roof area and ensured the new waterproofing and previously completed phase were compatible. We also liaised closely with NT Sweeting to make sure all products were available and delivered to site on time to avoid unnecessary delays to the roofing works.Our Excel reinforced bitumen membrane system was specified for the main roof area; the membrane is manufactured with the unique Alpa polymeric binder, making it our most technologically advanced RBM system.Axter’s Starcoat R cold applied liquid bitumen PU resin was used to detail combustible items picked up in our report, including interface to windows and cladding abutments in line with Safe2Torch guidelines, which eliminated all fire risk.

2-6 Cannon Street is a high-end new build commercial office building located in the City. This new-build includes an unusual shaped roof which has been designed to create a stunning exterior roof terrace. Buzon UK were commissioned to supply and install the DPH pedestal system to support GRAD decking and rail systems. This was a challenging project as steel planters were located in the middle of the roof terrace so the installation of the adjustable support pedestals had to be carried out around the planters. Timber decked steps and ramps were also part of the terrace design.

Two types of Welsh Slate roofing slates have helped breathe new life into the stunning Grade II listed dining hall of a top independent school. A total of 15,000 of Welsh Slate’s rectangular Cwt y Bugail and arrow-head Penrhyn Heather Blue slates now feature on the duo-pitch roof at Clifton College in Bristol. The three-storey dining hall/kitchen, which is one of, if not the biggest building in a cluster of stunning Victorian constructions, had not been re-roofed since it was built 156 years ago to a design by architect Charles Hansom.

Constructed in 1969, Lancaster University’s iconic chaplaincy centre is one of the first buildings that come into view when arriving on campus and amongst the university’s most architecturally distinctive. It features three circular roofs which rise in the centre of the building to create a three-pronged spire. The building has become an instantly recognisable visual symbol since being used as the basis for the university’s logo in 1989. The recent roof refurbishment project, delivered using Sika Liquid Plastics’ Decothane Ultra system, received the Liquid Roofing Project of the Year under 1000m2 at the LRWA Awards 2017.

ROOFINOX Tin-Matt is installed at Wansford Church following the theft of Lead roofing. Historic England accept Grade 316L as a suitable roofing material that offers both the required maintenance free and longevity. The surface of the stainless steel is electroplated with Tin which dulls over time to a matt grey. Tin-Matt is easy to solder and is 100% UV resistant and rust-free. An added benefit is the lightweight nature of stainless steel being under 4kg/m2, thus reducing the load on the roof dramatically, when compared with lead sheet which is often in excess of 30kg/m2

These railings were used on a roof terrace and lower floor balcony area. On the roof section the standard root fixed version was used, and a bespoke side mounted version manufactured for the lower floor balcony. These posts were cast in ductile SG iron to that they met and surpassed all loading requirements.

OverviewThis project saw the refurbishment of King Solomon International Business School, which was changing hands from office use to education. The building now features specialist science rooms, resistant materials workshop, drama studio, outdoor sports hall, music rehearsal rooms, food technology, ICT rooms and language rooms.ChallengesDue to the change of building use, a full survey of the roof covering was required. Excessive moisture was found within the existing asphalt covering, water ingress was present and the internal top floor of the building was not suitable to be used as a teaching space. The roof area presented many challenges with complex detailing to existing balustrade posts, live mobile telephone masts and large quantities of plant / M&E installed.SolutionsAs a starting point, the roof was completely stripped due to the high level of water ingress. The existing asphalt covering was removed ready for installation of a new Excel RBM system, with Hytherm ADH PIR thermal insulation. Much of the existing M&E was found to be redundant and could safely be removed from the roof area.The complex detailing to the balustrades and fire risk areas was simplified using Starcoat PMMA cold applied liquid waterproofing, allowing for a long term, robust and financially viable solution. High level roof areas were also detailed with ease using Starcoat PMMA. Successful installation provided a peace of mind roof covering for the next 25 years, supported by Axter’s Platinum Guarantee.Systems in useExcel®Starcoat® PMMA

We delve into Anna's inspiring rooflight replacement journey in her Hertfordshire home with a Vario by VELUX custom-made roof window. This stunning addition has wholly transformed her living space.At Vario by VELUX, we understand the importance of custom-made solutions to suit your unique needs, and our bespoke flat roof windows are designed to do just that. Anna's story is a testament to how our Vario by VELUX Rooflights can create a space filled with daylight, enhancing ambience and interior design.Custom Made Roof Window CollaborationAnna, who hails from South Africa and relocated to the UK almost 40 years ago, recognises the importance of natural light and how it can significantly impact your well-being. Having lived in her Hertfordshire home for many years, she knew it was time to replace her existing lantern rooflight due to a leak and a desire for a more modern design.When she reached out to her architect for guidance, he recommended Vario by VELUX, a decision that proved to be a game-changer for her home. Our team worked closely with Anna, making the bespoke flat roof window fit around the structural beam and seamlessly integrated with her living space. The result was nothing short of beautiful, highlighting the exceptional craftsmanship, professionalism and flexibility Vario by VELUX is known for.What improvements have you seen between the old rooflight and the new one?“The design of the extension is better now than when we had the previous rooflight. The lantern that stood up always bothered my eye and now this flat roof is unobtrusive. When I look out of my windows upstairs I don't see anything, I just see the garden, it’s just opened up another dimension.Another thing is the rain, the sound is different - it’s softer and I like the pool of water you can see lying on it - the different little patterns. It’s a wonderful sound and view so I really recommend it.”The Impact of Unlimited Daylight on Your HomeWith the Vario Unlimited Rooflight installed, Anna's living space now basks in abundant natural light. This daylight not only brightens up the room but also enhances the overall interior design. Even on cloudy days, the room remains well-illuminated, reducing the need for artificial lighting. The difference is undeniable, and Anna couldn't be happier with the transformation, stating, “I had such a good experience, everything was done so professionally… the end product is beautiful.”Advantages of Flat Roof Windows Over Lantern Roof DesignsWhen considering the choice between a flat roof window, like Vario Roof lights, and a lantern roof design, it's essential to highlight the benefits that make the former stand out:Unobstructed Views: Unlike traditional lantern-style skylights, flat roof windows can offer a more discreet and clean design that blends seamlessly with the roof. This design allows unrestricted views of surroundings, creating a more open and expansive feeling within a space. Lanterns can provide a beautiful and artistic effect by breaking up the daylight with the lantern intersections.Balancing Cost and Style in Skylights: Choosing between flat glass rooflights and lantern skylights isn't just about style but also cost. Flat glass rooflights are a bit friendlier on your wallet and can even help lower your heating bills, thanks to their excellent insulation. But don't let that sway you if your heart is set on a lantern skylight! They might require more time and expertise to install, but the result could be well worth it. Ultimately, the choice is yours - both options bring daylight and elegance.Ventilation: Vario flat rooflights are designed to maximise airflow thanks to our upstand, contributing to a well-ventilated and fresh interior space. Lantern roof lights, on the other hand, excel in aesthetics, adding a distinct charm to any room. However, their ventilation efficiency may not be as high as that of flat roof windows. Both options present a blend of form and functionality to consider.Insulation Differences: Lantern skylights and flat roof windows both provide insulation but to varying degrees. Lanterns with multiple glazing pane joints tend to have poorer insulation, leading to more heat loss. Conversely, flat roof windows, with fewer connections, generally offer superior insulation.There are certainly pros and cons to both types of rooflight design. What matters most is that you are considering adding more daylight into your your designs!Experience the ‘Wow Factor’ With a Bespoke Roof WindowAnna's advice when considering a renovation is crystal clear: "I really don’t think you can do an extension without a rooflight." She believes it's essential for well-being and making your space more enjoyable. A rooflight adds the "wow factor" that can genuinely make your life better.Incorporating a Vario skylight into your project can be a game-changer, just as it was for Anna.

Gloucester Transport Hub Bauder Thermofol PVC single ply waterproofing system SynopsisThe replacement bus station and regeneration of the surrounding area has created a unique and distinctive city centre building for the town. The design connects with Gloucester’s Roman heritage and association with aviation. The innovative roof design incorporated a canopy intended to reflect an aircraft wing that required a lightweight waterproofing and renewable energy photovoltaic (PV) solution.Bauder Building BoardProject:Gloucester Bus StationLocation:GloucesterProject Type:RefurbishmentRoof Size:1520m²Constructor: Kier Group PlcApproved Contractor:Kovara Projects LtdThe specificationThe Bauder Thermofol PVC single ply waterproofing system with the BauderSOLAR F PV solution met the brief precisely without compromising the aesthetics of the roof. This combination of Thermofol PVC single ply waterproofing system and BauderSOLAR F PV delivered a high quality, strong, energy efficient flat roof.This system was selected for the project because of its lightweight properties which complemented the deck and roof design. Light grey was chosen to reflect the colour of the cladding as the aesthetics was a key objective for the client.The OMG Rhinobond induction welding system was specified as the installation method which provided multiple advantages to the project, not only saving time and fasteners, but also optimising the field fix pattern of installation and ensuring that the load on the roof was spread between the induction welding plates. Products appliedBauder Thermofol U15 FR MembraneA high grade virgin polymer Thermofol PVC membrane ensures the optimum membrane characteristics to deliver high performance and a BBA stated life expectancy in excess of 35 years.BauderSOLAR F An aerodynamically optimised system for flat roofs using framed modules and mounting units, securing them to the roof using membrane-to-membrane welding techniques. This installation method means that the roof is not compromised by penetrations of fasteners or is it ballasted.Project challengesThe design of the Transport Hub and city centre location proved to be the key challenge to this project. The unusual roof configuration required a bespoke insulation scheme using BauderPIR M, an efficient rebated PIR insulation board, in order to achieve the required U-value of 0.18W/M²K.The deck configuration equally made the installation of the Bauder Thermofol PVC waterproofing system complex with the perimeter zone having to be carefully marked in compatability the wind calculation which included measuring factors such as wind speed, altitude, direction and exposure. Bauder and Kovara Projects were required to work closely together to ensure all criteria of the wind calculations were met. 40 modules of the lightweight BauderSOLAR PV solution were installed on the west side of the Transport Hub’s roof.The location of the project, Gloucester city centre, presented logistical challenges. Delivery of the roofing products had to be carefully scheduled and managed to avoid creating congestion in the area.The resultThe installation required constant co-operation and communication to embrace the live site operations within the restricted city centre location whilst allowing the bus station to remain fully functional. The roofing contractor delivered a superior standard solution and any complex issues that arose during the project were resolved promptly and collaboratively.System installedBauderThermofol PVC single ply waterproofing system  1 Bauder THERMOFOL U15 FR1.5mm polyvinyl chloride membrane (PVC) reinforced with a pre-coated polyester cross-weaved matting for mechanically fixed installations. 2 BauderPIR MThis efficient tissue-faced flatboard insulation has been specially developed for use within Bauder single ply systems. 3 BauderSYN DB-PE 100A blue, polyethylene air and vapour control layer.

THE PROJECTThe Bushey Heath building is the eighth development created by the Jewish Blind Association and consists of 15 one-bedroom and four two-bedroom apartments. The project cost £6.7 million and has multiple communal areas including a large roof terrace which is available to tenants. This was identified as an area which would require shading and shelter for tenants.THE CHALLENGEThe charity needed a shading solution which could be left out in heavy rain and still provide a suitable amount of shade.THE SOLUTIONTo achieve the desired 10000mm width and 5000mm projection we used the Weinor Pergotex II aluminium roof cover to protect the roof terrace area. This was designed to give residents of the Bushey Heath flats shelter from sun and rain due to the product’s unique PVC fabric panels. The addition of LED roof lighting helped residents use the area later in the evenings with spaced seating provided.

Located at Aberdulais Crescent in Cardiff, each of the twelve properties is a traditionally-built bungalow built fifty five years ago. From the outset, the roofing material utilised on each home was manufactured from metal, although they used standard metal sheeting instead of the advanced metal roof tile Metrotile produces.

Project descriptionDixons Academies Trust is a well-established multi-academy trust that aims to challenge educational and social disadvantage in Yorkshire and the North West.The trust transforms schools into safe and high-performing learning environments, enabling students from all backgrounds to realise their potential and maximise their opportunities after school.Alpha Roofing Systems was brought in to refurbish two roof areas at Dixons Croxteth Academy in Liverpool after the existing waterproofing failed.A number of complex challenges arose from the start; after stripping back the aged and failed single ply system, Alpha identified a water-saturated bituminous roof beneath, which also overlaid the original asphalt waterproofing.The excess weight imposed on the roof from the multiple, heavily saturated waterproofing systems led to cracking and depressions in the deck, as well as rusting of reinforcement within the structure.This meant that, before installation work could even begin, many hours of labour were required to remove the top two waterproofing layers to expose the original asphalt. What’s more, this work had to be undertaken both during term time and a period of heavy rainfall.Solution and installationAfter close consultation with their IKO business manager, Mark Taylor, the Alpha team selected the IKO ULTRA Prevent 25 waterproofing system for this project.To adhere to Department of Education requirements, a 35-year durability statement was necessary, so the long-lasting, durable finish offered by the IKO ULTRA Prevent system was ideal.Challenges continued to come thick and fast throughout the project; after stripping the roof back to the asphalt waterproofing, a large expansion joint was found near the clerestory window. Tapered designs were subsequently adjusted to accommodate.30 tonnes of waste material – primarily due to the uplift of the previous failed waterproofing systems – also had to be removed from the roof over the course of a week.Furthermore, complex design variables meant that Alpha could not fully determine the existing roof falls until the roof had been sufficiently exposed. Working closely with the IKO technical team, design information and solutions were identified to keep the project on track.To complicate matters further, Alpha was also required to carry out this extensive work during active teaching time. This presented not only additional health & safety considerations but also the need to minimise disruption.With a stringent construction phase plan and regular active monitoring, the project was completed with a zero incident/accident rate and excellent feedback from the client on Alpha’s approach to safety.Despite a number of hurdles and complexities to overcome, Alpha Roofing Systems delivered the project ahead of time and within budget, providing a low maintenance, long-lasting roof for Dixons Croxteth Academy and a satisfying outcome for all involved.

Glazing Vision have worked on a number of projects with Architects, ARCHEA, who are Victorian house experts specialising in adapting period houses into modern homes. These homes regularly demand an uplift in natural daylight, and Glazing Vision have formed a great relationship with ARCHEA to help transform many of their projects into well-lit, healthy, and happy environments for a number of families.These particular homes are all located within 10 minutes of each other in Hackney, London, with all clients looking to transform their period property into a contemporary home. Each project involved an extension and required a significant increase in natural daylight to help better the health and wellbeing of the families residing in each home which is where Glazing Vision stepped in.“When adding a ground floor extension, we often need to include rooflights to add light and views both to the new spaces and existing rooms in the home. Whilst fully glazed roofs can be used, this approach typically incurs more cost and extended lead-times due to the glazing being bespoke and needing to be made to order. By using large format, off-the-shelf rooflights we can incorporate extensive areas of glazing, but at a much lower cost and faster turnaround. We then use these in combination with traditional roof construction techniques, which are simple to construct and maintain.” – Richard Skinner, ARCHEA.ARCHEA regularly specify Glazing Vision’s Flushglaze Fixed Rooflight, a minimalist product with ‘frameless’ internal views designed to allow as much natural daylight into a room as possible. When working with pitched roofs, ARCHEA often opt for the Glazing Vision Pitchglaze Fixed Roof Window which is designed to be installed in pitched tiled roof applications flush with the tiling line, providing you with a vast amount of natural daylight.“We initially chose Glazing Vision because of their wide range of high-quality rooflights, and since working with them on a number of projects we value the help of their Technical Sales Team who are always on hand for technical support. We typically use the Flushglaze Fixed units as the extensions we work with usually involve a flat roof for practical and planning reasons and the Flushglaze offers the largest and best value standard glazing solution on the market. The standard aspect is vital for us as we are often looking for short lead times, and so this element adds so much value. When working with pitched roofs we instead use the Pitchglaze Fixed Roof Window which fit flush within the roof offering a sleek finish.” – Richard Skinner, ARCHEA.You can purchase our off the shelf rooflights and roof windows via rooflights.com, our online rooflight shop!Photography: Mai-ling Leung of ARCHEA

The National Trust visitor centre at Tarn Hows in the Lake District is set in a protected Site of Special Scientific Interest (SSSI). EPDM was specified for the roof because of its environmentally friendly credentials which have the backing of Greenpeace. Hertalan roofing products were chosen because of ISO9001/14001 and BBA certification. The membranes were a combination of factory vulcanised sheets and easy weld rolls which were installed in accordance with strict FLL/GRO guidelines. The specification for the green roof insisted on local species of sedum and had over 2000 plug plants installed into 150mm deep recycled growing substrate.
