"roof light"

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

TRC was appointed as principal contractor by Barker Associates in May 2019, to carry out specialist sash window restoration works.Trinity Primary Academy is a primary school located in Bounds Green Road, Wood Green, London. It was built in 1899 by Mitchell and Butler and consists of yellow brick and red brick dressings, tiled roofs, irregular fenestrations, and sash windows that give away its Queen Anne Revival style. It's currently categorised as a Grade II Listed building with Historic England, and is part of the Academies Enterprise Trust.Nature of the worksAs the building was Grade II listed, timber window repairs had to be sympathetic and complementary to the historic nature of the property. Many of the existing timber sash windows were inoperable due to the build-up of decorative coatings, timber degradation, and defective and broken sash window ironmongery, as well as opening mechanisms. The requirement was for the windows to be fully refurbished, repaired and operational as originally intended, but also modified to meet health and safety requirements.Phase one of the refurbishment of 200 sash and timber casement windows commenced on the area needing most attention: the west elevation of the building. Following the success of phase one, the client team extended TRC’s appointment to continue around the remainder of the building, systematically completing all other windows, door and roof light refurbishments.This overall refurbishment project included:Stripping back the existing paint from the historic sash windows and repairing any decayed timber.Repairing glazing as and where necessary.Improving the thermal and acoustic containment by installing draughtproofing.Repainting windows and installing ironmongery.Undertaking brick and stone repairs to the building’s exterior.This project also required our specialist attention on some specific areas of traditional glazing. This aspect of the project required the repair and refurbishment of all four oriel bay windows and the oriel bay glazed roofs. Completion included the supply and fixing of new safety glazing and hardwood timber roof rafters, along with the repair and refurbishment of the two existing openable roof lights. The supply and fixing of new code 4 lead flashing, with lead wedges, was also carried out and fully pointed with the correct cement mortar at the wall abutment.Additional detailed work throughout the project included the following:Removal of all existing fitted window blinds for refixing upon completion of works.Removal and repair of existing window ironmongery, including original mechanical winding gear, solid bar opening mechanisms, locking fasteners, slide bar restrictors, cable restrictors, handles and stays.Careful removal and repair of all internal fixed-glazed hopper units, casements and pivot openings.Removal and replacement of all cracked and broken glazing, and replacement of the existing Georgian wired-glazing, with 6mm safety glass or 4mm polished plate glass to areas up to 1.2m height from floor level. Where privacy was required, white opaque glass with thickness in accordance with above was used.Removal and replacement of all loose and defective glazing putties, and removal of all flaking, loose and built-up paint coatings.Exposure of all timber rot and decay ready for repair with Repair Care Systems products, followed by sanding and priming ready for decoration.Vertical sliding sashes repaired, refurbished and rehung on new sash cords and weights, and adjusted as needed. Sashes were routed to accept new brush pile weather stripping. New parting beads and staff beads were serviced with brush pile weather stripping where appropriate.Final internal and external decoration was carried out using Dulux or Leyland trade paints, allowing for one undercoat and one gloss finish.

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

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

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

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

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

Russell Roof Tiles supplied Taylor Wimpey with 180,000 Bute tiles, a thinner leading edge tile, in Burnt Orange for its Shopwykes Lakes development in Chichester.

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

Russell Roof Tiles supplied Taylor Wimpey with 250,000 sustainable Bute tiles in Cottage Red, Slate Grey and Terracotta, for its Hamford Park development in Walton-on-the-Naze.

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

In 2010, Protech where approached by The Clegg Group for a renovation project of an eight storey 1930’s building.Originally known as Shaftesbury House, the building was opened in 1938 to house migrant workers in Leeds that had previously been living in appalling conditions. The development had deteriorated and was eventually closed and boarded up in 1998. As part of a regeneration programme of the area, Leeds City Council co ordinated the redevelopment of the site into what is now known as Greenhouse, a mixed-use block of eco-flats.  Roofing:ROOFING: Sarnafil® Light Grey G410-15EL.Sika® S-Vap 500.120 mm PIR Insulation.Sarnafil® Walkway.

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

A stunning new ‘brown roof’ is the crowning glory for a private dwelling overlooking the River Tweed.

Lightweight but very strong mounting profileCHALLENGEStraight lines, maximum light and a unique, remarkable design. This is how independent architect Lieze Vandael saw her own home. Due to the numerous voids and imposing windows up to 9 meters high, a traditional construction method was certainly not an option. A suitable alternative had to be found. Moreover, Lieze Vandael wanted to see the elegant, minimalist architectural style with straight lines envelop the building: a roof and façade finish in the same material - preferably timber - and moreover, seamlessly blending into each other. To have the building completely wrapped in wood. Definitely a real challenge! A neat and watertight connection between roof and façade is not an easy job at all. Besides, timber is never completely waterproof. So, the challenge for Lieze Vandael was to combine the roof and the façade into one uniform surface, ensuring a perfectly watertight roof.SOLUTIONArchitect Vandael wanted to step away from the traditional lightframe wood structure, and opted for an alternative mass timber construction: a load-bearing construction formed from tongue and groove stacked solid wood beams. After all, this type of construction creates a lot of possibilities and is, besides, a more durable and ecological solution. For the exterior finish of the building the architect chose thermowood Ayous, a knot-free, clear-grade exotic hardwood providing excellent durability. The façade was finished with thermowood in a traditional way. Finishing the roof, however, was a more complex task. Cladding a roof with timber, particularly a highly sloped roof poses a substantial risk. How to achieve a watertight roof?

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