"roof finishes"

Project involved decking a 350m2 the rooftop of a commercial block in the heart of the city. The owners wanted to create a roof terrace for staff. The customer chose the iDecking complete solution for it's superior look. Installation was carried out on an inverted roof. The contractor laid down a double layer of our aluminium frame onto Wallbarn MegaPad pedestals which provide a stable footing for the framework. The composite Moor Oak boards were stamped into position. Installers were able to achieve a great finish by accurately cutting the boards to fit neatly to edges and corners.

A contractor client was working on a retro-fit balcony and flat roof project in Brighton. The waterproofing membrane had tapered insulation placed on top and the contractor discovered ballasting the insulation was needed, only once on the roof. The door thresholds were too tight for a traditional decking system with joists. Wallbarn advised for paving slabs on 9mm rubber pads; then 30mm thick ipe timber tiles mounted onto Adjustable Pedestals. The buildup was under 100mm and the overall finish of the tropical hardwood was glorious. The architect was relieved that we could produce a solution, the client was delighted.

Donaldson Timber Engineering Ltd designed and supplied these impressive curved top chord trussed rafters, to form the contoured roof of a Tesco Express store in Dunfermline. With six locations across the UK, Donaldson Timber Engineering use MiTek's engineering software and connector products to design and manufacture their roofs and floors throughout the UK

Russell Roof Tiles supplied 27,000 black Galloway tiles for a total of 27 homes on the unique island community project of St. Mary’s Island, Kent.

This was a relatively small installation of under 100 sq metres of asbestos roof coating and metal gutter lining. The asbestos cement roof was first cleaned using a closed box pressure washer, with all waste water being filtered to 2 microns. The cleaned roof was coated using Liquasil's BBA Approved asbestos roof coating system, Asbestoseal. The metal gutter was cleaned and thn treated with SWT (Surface and wet tolerant) corrosion primer. Joints were treated with Non-Sag Sealer and the gutter lined with Liquasil One to provide a seamless lining.

Metalseal 20 was specified as part of an industrial unit refurbishment project. Metalseal is the only BBA Approved metal roof coating on the market and the only one to come with a Latent Defects Insurance Guarantee. This is a single coat application, in this case, using brush and roller to avoid the risk of over-spray which can occur when using airless spray equipment.

Project:Architects Foster + Partners approached Surespan to design and manufacture two roof hatches for Circle Hospital Bath – the new centre of clinical excellence due to open in late 2009. Product:The huge single-leaf glazed roof hatches are electrically operated by push button switches, one hatch incorporating a side door. The high spec glazed lid is supported by heavy-duty aluminium hinges and features an integral ‘wrap over’ edge, incorporating double unbroken EPDM seals. The hatches offer a high level of thermal insulation against heat loss and condensation, together with excellent sound absorption properties.

City of Edinburgh Council required a new roof for one of its local authority primary schools, Parsons Green. Built in 1961, the school had a copper pitched roof which was in need of replacement, and an upgrade to the insulation of the building was also required. The council also required a 20 year single point insurance-backed guarantee and a reputable installing roof contractor.

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

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

Luxury countryside holiday letsAward winning architectural practice Pocknell Studio were tasked with renovating deteriorating, redundant, two-storey structures in addition to creating new field barns to create spectacular accommodation for a fabulous countryside holiday retreat.This architect has a long-standing preference for using Rainline for their projects so it was no surprise when the galvanised steel guttering and downpipes were specified for the North and South Barns. The Silver Metallic colour option was a perfect selection for the hipped roof design with black and white palette.The field bands are finished in a contemporary take on the traditional black Essex barn and designed to fit into a typical country environment. The brick and timber clad buildings are finished with not only Lindab Rainline rainwater system but also Lindab Seamline standing seam roofing system. The valley roof and staggered fascade design was a particular challenge which required careful detailing and installation to ensure steep falls which allow rapid drainage.Bullocks Farm have tried to create “a quiet haven for people visiting the area and have made each property as comfortable, relaxing and practical as possible”. The architects are very happy that the project has been successful for the client and further development of the site will continue.  

This project had a wide ranging number of detailing factors to overcome with cladding abutment details and change in levels to be redesigned and encompassed into a system that also drained the roof areas of their historic high levels of standing water. Some of the existing construction build had not taken into account any suitable maintenance of the roof with sections being completely inaccessible and thus reducing the performance of the waterproofing.

Powdertech Wood Finish enables architects to combine the look of wood with the strength and practicality of metal. At the same time, this high performance finish compliments the durability of metal and preserves its appearance for many years. PWF replicates wood with variation in colour, grain density and grain pattern. Instead of depleting timber resources, highly abundant and recyclable aluminium can be used. This is a far better material for forming the finely angled aerofoil blades for solar shading. Powdertech have coated thousands of linear metres of aluminium solar shading in various colours for over 20-years. A2 S1-d0 approved.

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

The roof of this bingo hall in Hamilton, Scotland was affected by cut edge corrosion. Liquasil's Flexlap cut edge corrosion treatment was specified to solve the problem. All surfaces were first prepared using wire brushes to remove any delaminating finishes, before being prepared with the Liquasil Corrosion primer. Once the primer had cured, the Flexlap hardened silicone top coat was applied to provide a moss and lichen resistant finish, offering 10+ years protection, all backed by Liquasil’s unique, Latent Defects Insurance Warranty.

The roof to a Waitrose distribution centre has been completely refurbished in a single ply membrane system chosen for its sustainable credentials and no disruption to the retailer’s 24/7 operations at Aylesford near Maidstone, Kent.

Over 2,300m² of Protan SE 1.2mm PVC single-ply membrane was installed in the Protan Prefabricated roof system at Wilmslow Garden Centre, Cheshire. The main driver behind the installation of this roof system was the time constraint placed upon the roofing contractor for installation of the roof. Using Protan's unique ProPlan CAD software, a bespoke solution was created for the project - prefabricated rolls of membrane measuring 3.96x8.00m were manufactured to span the barrels of the roof. This minimised on-site waste and reduced on-site hot air welding by 1,080 linear metres.

The meticulous refurbishment of this Grade II Listed landmark provides a stunning range of luxuriously specified apartments. Phase 2 of this project included the installation of FSC certified Hardwood decks to create a series of private roof terraces adjoining the larger apartments. This project was particularly challenging due to the many curved corten steel planters, upstands, steps and seating areas but using the Buzon PB pedestal range to support the decking our installation team achieved seamless surfaces across all the terrace areas. The finished private roof terraces provide residents with the perfect outdoor space.

This project, to coat approximately 2000 sq metres of asbestos roof with the BBA Approved Asbestsoeal system is a lesson for all in correct health and safety. Liquasil provides all approved installers with H&S training as standard. This deals with correct use of netting, scaffold, walkways, work platforms and waste water filtration from asbestos roof cleaning. Having already completed 500sq metres on a unit a year previously, the contractor was invited back to complete the rest of the block, which is the best possible endorsement.

A sense of community, abundant greenery and lake views on the roof terrace for all residentsThe housing fair is held annually in Finland. In 2021, it will be held in a scenic location in Lohja, Southern Finland. An interesting partnership quarter will also be put up in the fair area, where a sense of community has especially been taken into account in the planning. A block of 34 modern and energy-efficient apartments. The principal designer of the site is the architect Sasu Alasentie from UKI Arkkitehdit.”The idea behind the whole quarter is a sense of community. The flats in the building do not have their own saunas, but instead a communal use sauna will be constructed on the roof terrace. You can see the wonderful lake scenery from the roof and by utilising the roof terrace we wanted to ensure views of the lake to all residents. The yard areas of the quarter are fairly compact, but the roof terrace creates more greenery and communal outside areas for all the residents to use. We also hope that this will increase the residents’ team spirit and sense of community,” says Sasu Alasentie about the basis of the planning. ”On the roof terrace, we will also build an individual planting box for each resident, where they can cultivate herbs, flowers or whatever plants they want. A small summer kitchen corner and dining area will also be built there, as well as hanging chairs for lounging around. All in all, the area will hopefully become a communal, green oasis to spend time in, for all the residents,” says Sasu Alasentie. ”When we were choosing materials for the terrace, it was important to us that they would be in keeping with the building’s ecological nature and energy efficiency. Together with the contractor, we decided on the UPM ProFi Piazza composite for the terrace material. What appealed to us about it was particularly its durability and that it was easy to look after. Naturally also the fact that it’s made of recycled material, which fits well with the environmentally-friendly ideology of the whole building. I believe that in future projects, environmental friendliness and materials made from recycled materials will become even more popular,” says Sasu Alasentie.  

A project utilising our Del Carmen Spanish Slate took home the award for Roof Slating at this year’s UK Roofing Awards, hosted by the National Federation of Roofing Contractors (NFRC). The NFRC is the largest and most influential roofing trade association in the UK, promoting both quality products and contractors, while ensuring that its members are at the forefront of all roofing developments. Contour Roofing (Essex) was given the task of providing the roof coverings to St Joseph’s College, a Grade II listed building (1866) on the fringes of Mill Hill Village.

The screened rooftop garden which sits atop the new Westfield M7 commercial office development offers outstanding views out over London's skyline. PaveRail™ substructure system from RynoPaveSupport was used across the terrace. With a build-up of over 400mm to finished floor level and high-levels of foot-traffic, PaveRail will stay completely rigid and keep slabs in place.

This project was one of the largest schemes of its kind ever achieved outside of the capital, featuring the Aquamodul warm blue roof with our Force Dalle BBA approved system.Systems in useWilotekt®-PlusForce Dalle®Aquamodul®Extensive Living RoofChallengesThe roof attenuation rate required was 7litres/sec across the 6500m2, which is extremely low for such a large area, and the u-value of 0.10W/m2K was relatively demanding in terms of thermal performance. It was a project specific requirement that the roof was designed with falls within the slab in order to avoid any ponding water.SolutionsThe design and implementation of a site wide blue roof ensured the development’s contribution to mitigating flood risk in the UK, supporting 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.Wilotekt-Plus, second generation hot melt structural waterproofing system, 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 Force Dalle bitumen membrane with anti-root technology were later installed to complete the waterproofing and insulation system.Upon final QA inspection and integrity testing of the roof waterproofing works, the Aquamodul blue roof system, bespoke Hydrosoil Wildflower living roof and standard ballast finishes were installed in conjunction with a Solar PV array, which generated the majority of the building’s electrical energy requirements.
