"roofing contractors"

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

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

Cambridge University, Department of Civil EngineeringBauderBLUE STORMcell with BauderSOLAR G LightSynopsisThis new build project in the centre of Cambridge combines a Sustainable urban Drainage Solution (SuDS) with vegetation and renewable energy in a warm roof construction.The client for the Department of Civil Engineering at Cambridge University, R H Partnership, identified sustainability as being a key driver in the design of the roof, but also sought a single source supplier that could provide a guarantee for both workmanship and products. Bauder’s systems range encompasses products to meet all the sustainability objectives, and with our network of approved contractors carrying out the installation, we could offer the comprehensive guarantee that was required.Bauder Building BoardProject:Cambridge University Department of Engineering​Location:CambridgeRoof Area:1610m²Client:University of CambridgeSpecifier:RH Partnership ArchitectsMain Contractor:SDC LimitedApproved Contractor:Voland LimitedThe specificationTo meet the sustainability criteria set out by the client, the Bauder technical team designed a roof system combining an extensive blue roof, a green roof and a solar PV array. The first and most fundamental element of the roof system though is the waterproofing. Bauder Total Green Roof System (BTGRS) was selected as it provides robust and durable waterproofing with a life span in excess of 35 years, as validated by BBA Certificate 10/4744. The Plant E cap sheet has also been tested by the FLL to ensure long term root-resistance, making it ideal for use in conjunction with the BauderSOLAR G LIGHT system. The BauderSOLAR G LIGHT system is a unique way to combine rooftop vegetation with renewable solar energy. The PV panel mounting boards are held in position using the growing medium as ballast, meaning the waterproofing is not penetrated and therefore compromised. The mounting boards incorporate a water retention feature which allows a small amount of excess rainwater to be stored for short periods of time for the various plant species to feed from. The BauderSOLAR G LIGHT system’s unique mounting system lifts the panels above the vegetation allowing the plant life to grow freely and therefore qualify a greater area of the roof as biodiverse.In addition to the BauderSOLAR G LIGHT system, a blue roof was added to the build-up. Blue roofs are sustainable drainage solutions designed to manage stormwater on a flat roof to reduce water runoff rates and ease flash flooding and standing water in built up areas. The BauderBLUE Roof System attenuates water from a flat roof over a 24-hour period via a restrictive flow outlet. Calculations are carried out to determine the rate at which the water should egress the rooftop. This is determined by the local planning authority and is often set as low as 5-8 litres per second per hectare. With these calculations, Bauder can design each flow restrictorto meet the necessary runoff rate. For the Department of Civil Engineering, the main roof area of 1455.5m² required two flow restrictors, each with flow control holes to ensure the specified discharge rate of 0.77 litres per second was achieved. The maximum depth of water the roof is designed for is the H-max. When the water level reaches H-max, it will drain via the emergency overflow pipe. These overflow pipes are set at the same height as the H-max level. On this project the H-max was calculated to be 99mm. Although an unlikely scenario, this provision for a ‘once-in-a-hundred-years’ storm event will ensure that the structural integrity of the building is always preserved.Project challengesThe roof deck was constructed using a pretensioned concrete plank roof structure. Due to the large span of these planks, the dead load weight to the roof would be restricted. This being a blue roof with green landscaping and PV (a reasonably heavy build up), presented the issue of balancing the need of the roof design and the weight restriction of the supporting structure. To add to this challenging scenario, the pretensioned deck did not provide a completely flat finish. When installing a blue roof, a flat deck with no positive or negative falls is essential, as detailed in the 2018 update of BS 6229 – Flat roofs with continuously supported flexible waterproof coverings. To overcome this onsite challenge,the final deflection of the fully loaded roof was calculated and the concrete deck was screeded to give a flat finish.The resultBauder believes this project to be one of the first of its type in the UK to bring together so many rooftop systems in one space. Project management and clear communication was paramount in order to ensure a smooth installation. The Bauder project team consisted of green roof and solar PV product managers, area technical manager, technical design team, site technicians and approved installers for the waterproofing.With all the different elements being installed, green roof and solar PV product managers worked with our technical team to design the best possible PV array configuration for optimum energy generation whilst also qualifying for the maximum biodiverse area.Bauder site technicians worked closely with Bauder approved contractors, Voland Asphalte Ltd, to ensure works were kept to schedule and that a high quality of workmanship was maintained throughout.To ensure the landscaping is maintained, irrigation was installed by Access Irrigation Ltd. The system, Permadrip Pro, is a drip line irrigation system with anti-syphon design to resist clogging and pressure regulation. Due to the specialist nature of the irrigation system, Access Irrigation Ltd provided a bespoke design service.The result of this network of expertise was a multi-faceted support service for the client, specifier, main contractor and roofing and PV installers. System installedBauder Total Green Roof System (BTGRS)1 BauderPLANT E 42Green, 5mm torch-on root-resistant capping sheet.2 BauderTEC KSA DUOA self-adhesive, elastomeric, bitumen underlayer. This underlayer was used to ensure thorough sealing of lap joints in low temperatures when the roof was installed.3 BauderPIR FA-TETissue-faced flatboard insulation faced on both sides with aluminium foil to provide efficient thermal output.4 Bauder Super AL-ETorch-on air & vapour control layer. Once installed on the concrete pretensioned plank deck, it can act as a temporary waterproofing layer, allowing internal works to be carried out immediately which was a huge advantage on this new build project.BauderSOLAR G LIGHTThis BauderSOLAR G LIGHT system was a key factor in the specification of the project to meet the sustainability criteria specified by the client. 40 PV units were installed on the main roof area on the Departmentof Engineering. The forecasted energy generated for this arrayin its first year is 9.91MWh with a CO2 saving of 5.242 tonnes/a. BauderBLUE SR-B flow restrictorThe BauderBLUE SR-B flow restrictor is designed to be used in conjunction with a standard Bauder bitumen blue roof vertical outlet DN70. The flow restrictor is comprised of four parts; baseplate, overflow pipe, baseplate inner and baseplate outer seal. The polyamide baseplate fits within the 70mm vertical outlet, with the EPDM outer seal creating a watertight fit. The HDPE Overflow slots into the central hole of the baseplate with an inner EPDM seal preventing any leaks. The baseplate has a number (1-12) of 10mm restrictive flow holes bespoke to the project. The flow restrictor has no moving parts, hugely reducing the need for maintenance or risk of failure.

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

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

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

The Ascent Aluminium Roof Access Steps were specified to meet the clients requirement to create a safe access route up & over the “saw-tooth” roof for maintenance personnel. In this instance the Ascent steps were specified for use with an adjacent MSA Latchways climb-latch fall protection system.

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

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

A stable conversion project needed an authentic clay roof finish.

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

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

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

Russell Roof Tiles supplied Bute tiles in Burnt Orange for a residential housing project in Hampshire.

A green roof system was selected for this project as the client required a roof that would complement and accommodate the step in levels to follow timber decking lines to the 55m² roof terrace areas. IKO Single Ply’s Spectraplan SM120 light grey single ply waterproofing system was overlaid to the existing roof and newly built sun rooms, ready to receive a green roof system.

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.

On the Grand Union Canal in Hemel Hempstead, the Nash Mills Wharf housing development features a range of stylish new build 1-4 bedroom houses and luxury apartments offering high quality waterside living in this Hertfordshire town.With a waterproofing system required to protect the concrete podium above the ground floor car park, a selection of hot and cold applied products were provided by Proteus Waterproofing that met the requirements of the client Linden Homes. The licensed roofing contractor worked with Proteus Waterproofing on a dual system specification which included the fast and economical Proteus Hot-Melt waterproofing system, and for the intricate detailing around upstands and to avoid hot works around the plastic soil and vent pipes, the Cold Melt® waterproofing system was the ideal solution.Fast, hassle-free applicationWith the podium deck covering 3000m2, the Proteus Hot Melt® system was the optimum waterproofing solution for a robust, cost effective, seamless and fast application. This solution worked exceptionally well for the Licensed Contractor and is compatible with the fast applied Cold Melt® solution which was used for high detail items including plastic soil and vent pipes and upstands. There was also the added challenge of wet brickwork and an exacting building program to keep to. To overcome this problem, Proteus isolated the wet substrate with Pro-DPM Primer (Damp Proof Primer) which can be applied to green concrete 3 days old and then followed immediately by the Proteus waterproofing system. This enabled the Cold Melt® to be installed on to the vertical elevations will no loss of time.Quality controlProteus Waterproofing worked in close partnership with its Licensed Contractor to successfully deliver the project to a very high standard within the required timeframe.Long term performanceIncorporating 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.

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

With all products available from stock, the contractor ordered frameworks in stages, to suit the phased project programme, and eliminated having to find space within an already restricted working environment for everything to be delivered at once.

New school construction with biosolar wildflower roof system.

Last year, fast food chain Burger King added forty-eight new restaurants to their rapidly growing portfolio. Twinfix were approached by Ideal Building Systems to design, manufacture & install canopies and Brise Soleils at three of the sites in Kent, Clacton-on-Sea and Swindon.With over 30 years’ experience the Twinfix Technical Team had no problems designing structures to suit the requirements and budget of the client.Twinfix’s expert team designed, manufactured, and installed a brise soleil which covered all four sides of the restaurant at the first site in Swindon and fabricated lean to mono-pitch canopies with squared posts and 3mm thick solid aluminium sheet for roof, complete with brise soleil for rear, sides and front at the restaurants in Kent and Clacton-on-Sea.The structures served two purposes, while providing shelter, they also enhanced the aesthetics of the restaurants and complemented the building’s exterior.Each canopy spans 35 square metres and the roof comprises of pressed aluminium roof at a reduced pitch to fit inside the 150 depths of our frame, concealed gutters and downpipes and prepared for soffits by another contractor. The roofs were powder coated in RAL 3020 Traffic Red and squared aluminium posts powder coated to RAL 9006 White Aluminium.The Brise Soleils are constructed from our 150 x75 rectangular hollow section and had to accommodate some wiring for lights that were installed later by another contractor. These are a striking addition to the building fascia.The design of the proposed future sites look set to follow the same format and we look forward to working with Ideal Building Systems on the upcoming projects.
