"roofing membranes"

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.

A DOFF steam cleaner was used to thoroughly clean the moss and lichen from this asbestos roof in Bridgwater. The metal fixings were treated with Liquasil's rust tolerant primer and then sealed, along with cracked sheets, using Non-Sag Sealer, before the whole roof was coated using Asbestoseal 20. The end result was a leak-free asbestos roof that will last for many more years. Asbestoseal is the only BBA Approved coating system for asbestos roofs.

Eastbourne station is located in East Sussex. It was originally built in the 19th century and is classified as a Grade II listed building. Over the years, the station has undergone several renovations and upgrades.Back in October 2020 it was announced £5 million would be spent on restoring Eastbourne Railway Station to its ‘former glory’. Work done includes canopy refurbishment, slate roof replacement, masonry work to the front of the station, and new roofing above the atrium.Twinfix were approached to replace the glazing panels on the 32 lanterns on the station’s train shed with something hard wearing, sustainable and modern but without losing the period look. The change was needed because, according to the plans, the existing fixtures were ‘life expired and inefficient’.Twinfix supplied their Multi-Link-Panel Non-Fragile (NF) roof glazing system, glazed with 6mm solid obscure polycarbonate. The new glazing spanned 1243 square metres and was installed by Gable, on behalf of Main Contractor BAM Nuttall.The Multi-Link-Panel NF system is an innovative roof glazing product that has been well utilised for many years on station canopy roofs, and it has been thoroughly tried and tested in that time.It was the chosen system for this project for a number of reasons:sustainability– these panels are virtually unbreakable in manufacture, transit and in situ, meaning that, unlike glass, maintenance costs will be eliminated. The system is also completely recycleable.safety– Twinfix Multi-Link-Panel NF (Non-Fragile) conforms to the HSE recommended test method ACR[M]001:2019 (as outlined in document HSG33) and achieves a ‘B’ Classification.off-site construction– The panels are pre-assembled in Twinfix’s factory ensuring strict quality guidelines are adhered to, which is not always guaranteed when roofing products are assembled on site.ease of access– The Multi-Link-Panel NF system can be fitted with In-Line Access Hatches, to allow cleaning of gutters and roof. These hatches are hardly visible and allow safe access through the glazing without needing to get on the roof.weight– The Multi-Link-Panel NF is light in weight and due to its modular format, it is very quick to install which allows for short rail possession works. A slight redesign of the original roof allowed 96 access hatches to be installed, making maintenance easier. Installed it’s almost impossible to detect the modern materials that have been used to bring this historic structure back to life.During the renovation work, Shaun King, Sussex route director for Network Rail, said, “The quality of work on site is being completed to a very high standard and we’re taking great care to restore the Grade II listed building to its former glory.”

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

Specified because of it's unique BBA Approval and Latent Defects Insurance Guarantee, Asbestoseal was applied to this asbestos cement roof in Warwickshire. The roof was first steam cleaned using 150°c steam, removing all moss and lichen. Metal fixings were treated with Liquasil's corrosion primer and then sealed using Non-Sag Sealer. The entire roof surface was then coated with Asbestoseal 20 to provide long term protection and add considerably to the life of the roof. The metal gutters were lined with Liquasil's seamless silicone gutter lining system

IKOpro Acrylic Roof Coat has been used to provide a quick (taking only 4 days to complete) and seamless waterproof solution to a leaking roof at Bellman’s Auctioneers & Valuers in West Sussex. Contracts Manager for M Holmes Construction (contractor) admits that it was much less labour intensive than traditional roof refurbishments. He said, “The beauty of this system is that you don’t have to re deck the roof, unlike some alternative liquid systems. So this means you save one day of labour, typically four men on a job this size, plus material costs.”

One of the roofs within the scheme, Hodge Clough School in Oldham, had fallen into a dilapidated state of disrepair and was in great need of replacement. Council building surveyors came up with the appropriate specification and project managed the scheme to completion. The majority of the much-needed work took place at the school over the summer holidays in order to minimise disruption to the teaching programme, a major consideration for roofing works at schools, colleges and universities.

Stow House is a boutique bed and breakfast set in the heart of the Yorkshire Dales. They had the Topseal waterproofing roofing system installed and a sedum roof to finish the new extension.

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.

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.

Russell Roof Tiles provided Galloway tiles for a Social Housing project in Bristol.

Bath Western Riverside development is a multi-award-winning project for client Crest Nicholson Regeneration. The project has won multiple awards including the coveted NHBC ‘Pride in the Job’ award for H&S and the seal of excellence for quality.Systems in useExcel®ChallengesThe ‘curved’ bulk-heads, walls and interior finishes presented a special challenge to our on-site team, one that would be present over multiple floors and apartments.The system needed to be both robust and aesthetically pleasing, as the roofs are overlooked by residents and used as amenity spaces, and the colour had to be in keeping with the traditional Bath stone.In addition to this, the project featured many unique and complex terraces in terms of shape, threshold height, u-value requirements and access.SolutionsTo achieve both a level threshold and a good thermal performance, we designed a unique tapered insulation scheme for the terraces, utilising our Excel system, reinforced bitumen waterproofing membrane, in combination with our high performance and cost effective Hytherm VIP (Vacuum Packed Insulation) insulation scheme.To meet the aesthetics guidelines dictated by the local planning authority, the capsheet membrane was specified with a white granular finish, which provided the unique look the authorities were looking for.To ensure the terraces were installed correctly and in accordance with Axter requirements, we worked in close partnership with the development construction team. In conjunction with Avonside, a ‘traffic light’ system was introduced to ensure that each individual terrace had been checked by our Quality Assurance team, that it had been independently integrity tested and that it was installed in accordance with the architect’s details, upon which the guarantees were issued and the finishes thereafter installed.

David Wilson Homes were looking for a mix of slate and clay roofs for a new site in Andover.

In a stunning architectural statement, CUPA PIZARRAS R17 slate has been specified to meet the design challenges of a former Georgian windmill renovation at Fort Green, near Aldeburgh in Suffolk. The first project of its kind in the UK, the natural slate was individually cut and fixed through expert craftsmanship to accommodate the building’s exterior curve while also providing crucial protection from the harsh coastal environment. Originally, the windmill walls were going to be clad in cedar shingles however, contractor ELC Roofing recommended using the rectangular CUPA R17 slate from CUPA PIZARRAS as a more weather-resistant alternative. ELC Roofing Owner, Edward Carlo, explains: “The R17 is a natural, non-carbonated blue-black slate with non-rusting metallic particles and thin laminations. From our perspective, it’s a tried and tested product that we specify and install on a lot of our projects – especially in coastal situations like this.” The slates, which protect against the salt water and wind, have been fitted on both the windmill’s curved wall, its pitched roof and elsewhere adding design details to the property’s walls. He goes on to say: “Aesthetically, the ocean environment has inspired the material choice with the slate mirroring the scales of a fish. This gives the windmill a dramatic architectural style; one that also sympathetically ties into the slate roof of the neighbouring cottage, which we replaced with CUPA R17 the previous year. “As far as I am aware, nothing like this windmill has been done in the UK. It was a case of starting from scratch to devise the optimum installation method, which involved a lot of detailed calculations.” For the tower, which has a 15m circumference at the base tapering to 11m at the top, the team initially removed the thick render on the windmill wall, taking it back to the original brickwork. Next, to meet the challenge of the curve and tapering of the wall, 50mm counter battens were fitted to the tower’s brickwork. Then, multiple strips of ply were cut and glued together to create the curve. These panels were screwed to the counter battens to provide an anchor for the fixing system. The ply was also primed to protect the surface from water ingress and a breathable membrane applied to protect the brickwork. In terms of fixing the slates to the panels, Edward said: “For a more corrosion and wind-resistant solution, I decided on the French technique of a stainless steel hook fixing system to install the slate, as opposed to nails.” Ensuring the layout worked exactly with the curves, the slate was lasered from top to bottom to perk it out, which took five days to do. Horizontal tiling battens were also marked to ensure the slates were fixed at the right height. Every single slate was cut and fixed individually to accommodate the curve and ensure they aligned with the building’s inset windows as well as other architectural details - a very precise process that required expert levels of craftsmanship. Preventing the slates from getting smaller at height, the team designed-in a series of lead bands that go all around the building at each storey level. These sit underneath the windows to create a consistent appearance visually. The windmill’s domed copper roof existed already and the adjoining tower, which is horizontally clad in a white weatherboard, features a slated pitched roof. ELC Roofing has again used CUPA PIZARRAS spanish slates. In this instance, the roof curves to the back end with four leaded hips to one end and two to the other with a connecting lead ridge. This time the slates were fitted to 20 x 50mm battens with a layer of permeable membrane. This part of the roof also features a striking onion-shaped finial. Expertly crafted by ELC Roofing, the finial is produced out of a patchwork of small pieces of soft copper, topped off with a fish that acts as a weather vane and includes stunning marble eyes. To the other side of the clad tower, CUPA PIZARRAS slate has been used to create a vertical square panel detail to the front of the building and fixed using the hook system again. Commenting on this challenging project, Edward said: “Work on site started before the first Covid-19 lockdown so as well as the challenging weather conditions that a coastal location like this presents, the team also had to complete the work with government guidance and restrictions in place. Regardless, the client is overwhelmed with the end result and so are we.” To find out more about the CUPA PIZARRAS range of natural slate visit: https://www.cupapizarras.com/uk/natural-slate-roofing/

A large new housing development in the East Midlands required a roof tile that would match with the traditions of the local area.

The Residence required fast, robust hot melt waterproofing that met the demanding construction programme.ChallengesThe fast construction programme on this project imposed stringent requirements with regard to design, delivery, installation sequencing and coordination with Axter’s on site Quality Assurance (QA) team.The rapid build programme meant the waterproofing system needed to be capable of withstanding construction traffic and activity from other trades, with limited protection. Complex roof, elevation and cladding interface construction details resulted in the need for on site bespoke waterproofing detail design change, that maintained guarantees and ensured a defect free construction for the lifetime of the building.Restricted site storage and delivery access combined with the complexities of inner London construction challenged Axter’s logistics team to provide multi-vehicle, timed delivery without risk of delay or programme disruption.SolutionsThrough early involvement in the design process and collaboration with the developer and project architect, it was agreed that Wilotekt-Plus, second generation hot melt structural waterproofing system, was the right solution. The pour and roll application significantly reduced installation times, ensuring all areas were waterproofed quickly in time to receive a variety of roof finishes – living roof, paving, solar panels, etc.Wilotekt-Plus was installed fully bonded to the concrete slab, providing a robust, 7mm thick, self-healing system capable of withstanding significant construction traffic without defect.Upstands were completed using Cityflor root resistant bitumen membranes. Complex details, where a fire risk was identified by Axter QA, were completed using Starcoat QC in accordance with Axter specification requirements and the National Federation of Roofing Contractors (NFRC) Safe2Torch guidelines.Our accredited Axtershield Installer Bracknell Roofing Ltd followed the project specification in full and works were completed to a very high standard. Regular on-site quality checks were conducted by Axter QA personnel to ensure guarantee procedures were followed and programme deadlines were met.AcknowledgmentsAxter is a company with technically advanced products. Every site is quality checked by Axter QA and I receive a clear report. It’s good to have a partner committed to our joint success and capable of dealing with the unexpected.M Gorick - Bracknell Roofing Ltd

The client desired a green roof at the back of this beautiful family home. Access was very restricted. The speed and ease of transporting and installing our modular trays meant minimum disruption for the homeowner. Trays were delivered to site on pallets and handballed to the roof. The modules were laid down onto a geotextile fabric. Pebbles were then laid around the perimeter between the trays and any outlets to provide the required firebreak. Vegetation blended quickly creating a seamless green roof and, looking out from the upper floors, a sense of continuity from the house across the garden.

The Green Roofs Consultancy report looked to the provision of Green Bio diverse roof to address the need to encourage additional species. The ABG Green Bio diverse Roof System includes a mixture of plug planted sedum, cuttings and seeded annual and perennial wildflowers. ABG Roofdrain was used as a reservoir and drainage base layer to optimise water retention and prevent ponding. Special provisions were made to create hibernicula for local endangered species. The roof will benefit the building by providing additional insulation and reducing noise pollution.The roofs substrate filters out dust and pollutants helping improve the environment nearby

This doughnut shaped roof was a challenge due to its shape, but due to the versatility of Topseal GRP all of these obstacles were overcome with outstanding results.

Topseal PU was installed on this failed felt roof on this hotel. Due to it being a hotel, it had to remain open throughout the contract without disruptions.

The 55,000m2 roof area of one of London's busiest train stations was in an advanced stage of deterioration. IKO PLC liaised with roofing contractors Weatherproofing Advisors to refine the specification. Working with the public, and in a commuter environment, Weatherproofing Advisors had the added challenge of completing the project through one of the worst winters in 50+ years.

The challenge was to incorporate a green roof finish both flat and curved to the roof areas. The roof pitch being as steep as 45 degrees in places, a pitch not conducive with a green roof system. ABG used their expertise in green roof and slope stabilisation to make the curved green roof possible. The system incorporated a series of anchor points, reinforcement geogrid (Trigrid), and geocellular technology (Erosaweb) to retain growing medium on each roof. The Green Roof system incorporates a SMART rain sensor and automated irrigation pipe system with each finger haveving its own dedicated mains operated tank

This large new-build structure required to be waterproofed to meet BS 8102:2009, the British Standard for the Protection of Structures against Water from the Ground requirements. As it is not possible to determine the amount of potential water pressure surrounding the structure, BS 8102:2009 states the waterproofing designer should expect a head of water against the structure at some stage during the structure’s service life.

The scope of this project was to provide an effective, maintainable, and robust waterproofing solution to a below ground extension and underground garage to a residential home in Suffolk.Delta Registered Installers, Oaks Damp Proofing Co Ltd along with Delta’s Technical Sales Consultant Paul Callaghan, were appointed as Waterproofing Specialists to undertake the waterproofing design and installation of the waterproofing solution.Basement extensions provide opportunities for increasing a property’s footprint. Basement extensions have the potential to enhance living circumstances, from storage to additional bedrooms or pleasurable spaces, such as games rooms, libraries, or swimming pools. All structures, however damp, degraded or contaminated can be retrofitted into a dry, fully functioning habitable space.Whether retrofitting a waterproofing system or installing a new waterproofing system, BS 8102:2022 protection of below ground structures against water ingress. Code of Practice should always be incorporated into the waterproofing design.The qualified waterproofing design was to achieve grade-3 level and to incorporate two forms. Combination waterproofing systems (two forms) can offer optimal structural protection against water ingress. Where a combination of waterproofing protection is being used, the two systems should offer different performance characteristics to mitigate the risk of failure due to a common cause. The compatibility of the different protection types should be assessed in order to minimise the risks and negate the need for remedial measures.A combination of two forms of waterproofing is preferred when designing a habitable space.
