Basildon & Thurrock University HospitalBauder Total Roof System (BTRS) and LiquiTEC cold applied waterproofing systemSynopsisBasildon and Thurrock University Hospital’s existing roof was failing in multiple areas, and 80 rooflights needed replacing. The client wanted the refurbishment to make as little impact as possible on the departments directly below which included drug refrigeration, x-ray and ultrasound clinics, patient wards and operating theatres.Bauder Building BoardProject:Basildon & Thurrock University HospitalLocation:EssexProject Type:RefurbishmentRoof Area:900m²Specifier:NHSApproved Contractor:Breyer ConstructionProject challengesThe plant on the rooftop could not be turned off or raised and many of the AC units and boilers had to be left running due to the nature of the rooms below. Certain areas had to be repaired before others and detailing under and around the plant that could not be raised was almost an impossible task. When working around the plant, COSHH regulations had to be considered and adhered to.The result Coordinating with both the client and approved contractors was key in this project, and by using cold liquid applied waterproofing the contractors could ensure a watertight seal with quick application, allowing them to complete the remainder of the roof using reinforced bitumen membrane, and meet the tight project deadline of 12 weeks.System installedBauder Total Roof System (BTRS)Suitable for a variety of applications on both new build and refurbishment projects and can be used in warm, cold and inverted roof scenarios.1 Bauder K5KA top quality, heavy duty, torch-applied SBS elastomeric bitumen capping sheet.

The product features an aluminium foil facing for vapour impermeability.AdvocacyBreyer Roofing’s Contracts Manager for the project, Kerry Cutts:“The main challenge was working around the hospital’s requirements. For example, we provided a weekly plan for the areas we were working in and the rooflights / plant affected. Where possible, we worked out of hours while doing rooflight replacements to minimise any issues. We also worked closely with Bauder to vary the specification when we had to work around live plant. The communication between Bauder and Breyer Roofing was exemplary throughout and I was pleased this completed project was nominated for a national award."

The roof project in Bermondsey consisted of an accessible green roof for residents on the first floor and a green and brown roof at the next level. Natural Aggregate, 6mm Barley Beach. London

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.

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.

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.

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.

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. 

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.

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.

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.

Two types of Welsh Slate feature on the new roof of London’s Irish Embassy. The £2.5 million re-roof of the Grade II listed Irish Embassy in London, with more than 10,000 Penrhyn Heather Blue slates from Welsh Slate, has required its own exceptional levels of diplomacy. DarntonB3 Architecture had multiple challenges to factor in when it came to specifying the replacement slates, including the City of Westminster’s planning department, which was keen to see as many of the existing slates re-used as possible and required convincing to embrace the “new” metric sizes. Then there were landlords Grosvenor Estates, leaseholders the Department of Foreign Affairs and Trade, and Historic England, not to mention the site being opposite Buckingham Palace, on a “Red route” with diplomatic bays nearby, and between two of the most important Conservation Areas of Belgravia. Work began on the landlocked Grosvenor Place site in March 2018, a year after DarntonB3, who are specialist conservation architects, were appointed to oversee the project, and has just completed (January 2019). Two types of Welsh slates have been used on the former terraced town mansion with decorative metal roof crest that was designed by architect Thomas Cundy, who was surveyor to the Grosvenor Estate at the time, and built in 1868 in a French Renaissance style. Roofing contractor Mundy Roofing was involved at an early stage in the project and were ultimately appointed as principal contractor. Specialising in leadwork and natural slate roofing, they were pivotal to the project’s success. A total of 600m2 of County-grade 500mm x 300mm slates have been used on the numerous standard 30° to 35° pitched roofs while Capital-grade bespoke arrow-head slates of the same colour but sized at 400mm x 250mm were used around dormer windows on the 80° mansard roof elements that are reminiscent of Paris and feature lead secret gutter detailing around the perimeter. There is also some vertical slating to the rear elevation.  The old 5mm to 7mm thick slates had been on the roof since it was first built 150 years ago. The rectangular ones had been slightly longer and narrower, at 510mm x 255mm, while the arrow-head slates had been smaller all round, at 350mm x 200mm.  But a roof survey showed they were not laid to the correct bond or headlaps and fixing points were far from ideal and non-existent in places (the headlaps between 0 and 50mm), leading to the hardened sarking underneath becoming sodden in places. In fact, most of the roof had been repaired over the years with different types of slates using temporary lead tags or painted with a bitumen solution in an attempt to prolong its life. DarntonB3 argued that if the roof was re-installed as existing, its appearance would alter as they would have no option but to lay the slates at the correct headlap which would create additional courses. In addition, using the slightly larger arrow-head slates for the mansard roof would enable them to form a more robust detail at the abutments to the dormers and party wall.  Home to the Irish Embassy for the past 70 years, the building comprises office and entertainment space. The traditional timber truss roof featured timber sarking boards with penny gaps, a form of construction usually found in Scotland. The slates were then fixed with copper nails directly to the boarding without any timber battens. Once city planners had agreed to 100% replacement of the Welsh slates, at the new metric sizes (a process that took a year), the addition of timber counter battens, to improve ventilation of the roof and prolong the life of the new slates, was also proposed by the Architects. Mundy Roofing produced sample comparison mock-ups to demonstrate to the conservation officer this change would not be detrimental to the building’s character. As it is, the interface details where slates have been lifted has not altered the character of the building and the introduction of battens would not be known by the general observer.  DarntonB3 senior associate Matthew Jones, who was project manager and lead architect throughout, said: “Westminster City Council are regarded as one of the leading conservation-led councils in the UK, with some of the highest standards and criteria to meet, and dialogue with the conservation officer was detailed and robust. The need for wholesale replacement of the existing slate due to them being at the end of their life was a delicate decision and sufficient evidence of this necessity was proven. The replacement of the slates with metric sizes was also an extensively discussed item but the principal contractor and Welsh Slate worked with us to develop the narrative.” Keith Hamilton, an architect accredited in building conservation, acting for DarntonB3 alongside Matthew was reasonably sure Welsh slates had been used previously but was keen to ensure the correct thickness and grading were eventually used throughout the renewal process.  He said “We have specified Welsh Slate on numerous other projects and their reputation for the highest quality precedes them. We were able to argue the merits of increased ventilation behind the slates using cross battening in lieu of direct nailing to the existing sarking board, which in the majority of areas had survived over 150 years’ performance. “The risk of lack of ventilation on the lower roof pitches behind the slates was particularly relevant at the eaves and head. We had previously considered introducing slate vents and felt underlay to augment any need for ventilation but the existence of the ‘penny gaps’ in the sarking boards encouraged us, to believe that this was not required.  “This was another point of continued discussion with the conservation officer who was against an underlay in this instance. The timber sarking was found to be in remarkable condition considering the lack of existing underlay and the direct fix of the slates, highlighting the quality of the original slates. Hence, there is no secondary layer apart from the slating itself and we trust the quality of the new Welsh slate will replicate the existing quality and last another 100 years.” Due to tight access on the roof, they were also able to widen the lead gutters and set back the lower courses of slates to avoid getting them broken. All the new Penrhyn slates were holed and traditionally fixed with 38mm copper nails as opposed to clipped or other methods. The standard-size slates were able to cope with the wide variation of roof pitches and new rooflights encountered by varying the lap and gauge slightly. In virtually every case, the slate junctions are with lead or copper flashings and as it was appreciated there is some risk of staining, all lead was treated with patination oil. Using new treated timber battens for fixing the new slates proved a great success as direct fixing into the old hardened sarking boarding would have been a major problem and time consuming.  Matthew said the support they had received from Welsh Slate had been “fantastic” and included a site visit to match the type of slate, a letter explaining the need to change from imperial to metric sizing, technical drawings of the arrow-head slates, technical information on the end life of slates and their unsuitability for re-use, on-time deliveries with little if no wastage, and recommending experienced slating contractors. Mundy Roofing were on site for a total of 10 months. Work included the rebuilding of three chimney stacks, involving 30 tonnes of stone and brickwork, and restoration of traditionally-forged wrought ironwork to the pavilion roof crest, all underneath a temporary roof. Russell Mundy said: “This project was extremely challenging due to it being a working embassy but Welsh Slate were excellent with their support in achieving planning consent and the product has received widespread praise from the client.” Matthew said: “Due to the extremely difficult access to this roof, we were conscious to use a slate that will require little maintenance (if any) and satisfy appearance for an extended period of time. Welsh Slate were able to provide technical studies comparing different types of slate and their longevity. This enabled the landlord, Grosvenor Estates, that the new roof should outlast the previous roof and match it entirely with other buildings nearby. Welsh Slate’s evidence on the existing slates being at the end of their useful life, and the lifecycle information of the new slates, helped give the conservation officer comfort that the right approach was being taken for the building.” Keith added: “Essentially, Welsh Slate ensured we got the right slate, quality, consistency and sizes for the varying roof pitches and conditions. There have been no problems with mixing batches or colour variations which can occur. They also met the stringent programme requirements, reducing risks of delay from the main contractor. To our knowledge, there have been no rejects on quality of slates. “The final result is the new slating looks exactly like it was envisaged in 1868, except with the knowledge it is better-fixed and easier to reach for maintenance, with a discreet fall arrest system fitted. The client is extremely happy with the quality of the final works.” Andrea Fox, senior architect with the property management unit of the Department of Foreign Affairs and Trade, said: “The team have provided us with an exceptional and beautiful project that we know will stand the test of time and one we are extremely proud to have commissioned.” “I want to thank the Welsh Slate team for the support they provided during our project and especially in relation to protracted issues relating to the listed building consent approval.” 

Topseal PU was specified over numerous roofs on this hospital covering 1000's of metres. Topseal PU was chosen due to its BBA certification, high performance, 25 year guarantee, low odour together with the failed asphalt roofs and amount of plant on the roof it was the perfect product.

Flat roof waterproofing in the UK

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.

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

CUPA PIZARRAS has been specified across a major development and refurbishment at Tregenna Castle. The company’s products were selected for their ability to endure extreme local weather and provide an exceptionally long lifespan.Delivering spectacular views of the St Ives coastline, the Castle Approach Estate is a new collection of lodges built in the grounds of the historic Tregenna Castle Resort.Looking to complete the exclusive lodges, roofing contractor, Summit Roofing Solutions utilised a number of CUPA PIZARRAS’ products. Likewise, the project team also chose to use the company’s natural slate to complete a renovation of Tregenna Castle’s original roof.The lodges and castle are subject to difficult coastal conditions, including extreme winds and sea spray. As such, the project team needed access to roofing solutions that could deliver long-lasting, durable performance. Likewise, given Tregenna Castle’s status as a Grade II listed property, the team had to ensure that any selected products were able to deliver a traditional aesthetic, whilst still providing modern performance. Fortunately, CUPA PIZARRAS natural slate was able to meet all the desired criteria.Therefore, roofs on the lodges at Tregenna Estate exclusively used CUPA PIZARRAS’ 400mm x 200mm CUPA 12 natural slates, fixed using 100mm stainless steel hooks that were also produced and supplied by CUPA PIZARRAS.Notably, Summit Roofing Solutions was able to install the natural slate as a closed mitred hip system. In doing so, the project team ensured that all slates lined up perfectly with one another, which is only possible on account of the products’ uniform size and quality. This was particularly important on the lodges, where sections of roof were stepped down in certain locations and visible from ground level. Speaking on the project at Tregenna Estate, Adam Palmer, Company Owner of Summit Roofing Solutions commented: “Upon receiving the brief, we recognized that CUPA PIZARRAS’ solutions could help us to meet all key project goals. What’s more, the company helped us to overcome logistical challenges.”Following project completion, the Tregenna Estate played host to key stakeholders attending the G7 Summit in Cornwall, including the Prime Minister and US President Joe Biden. In anticipation of the event, enhanced security provisions were put in place on the site, which made the logistical side of the project more difficult.Thankfully, through its extensive distribution network, CUPA PIZARRAS was able to devise a well-considered delivery and logistics plan to ensure that supplies could reach the project team at critical times.CUPA 12 was chosen for this prestigious project as it is a high quality dark grey slate with a smooth finish. With a life span of more than one hundred years and very little maintenance required, natural slate is a durable, weatherproof product, un-matched by artificial alternatives. CUPA 12 has also received approval from Snowdonia National Park as a Welsh Slate alternative and has been certified by BRE Global as A+ for its quality, transparency, and sustainability credentials.

Waterproofing of flat roofs in industrial areas in the UK

The Gatehouse in Whaddon, Milton Keynes required a complete roof renewal with a new roof lantern installation. Over the years, the roofs had undergone several failed repairs, therefore, the client required a robust, cold applied, cost effective solution. Proteus Waterproofing specified Proteus Pro-Cold® as it's a single pack, fully reinforced polyurethane system that is cold applied, seamless and elastomeric, providing up to 20 years further life to the structures it is applied to.High Performance WaterproofingThe existing roof was a EPDM roof that had to be completely stripped. The deck was replaced and a complete warm roof build up, including Proteus Pro- Therm PIR insulation boards, was installed and finished with Proteus Pro-Cold®.

The purpose: Energy savings of £¼million over 20 years at just two of its sites are predicted to be achieved by London Fire Brigade through effective roof refurbishment using our Roofing Solutions. The brigade identified that the roofs at Erith and East Ham Fire Stations were in need of refurbishment. Numerous intermediate repairs had already been undertaken. An efficient solution was needed to help London Fire Brigade optimise best value in its asset management and reduce its requirement for planned- or unplanned- maintenance.London Fire Brigade therefore turned to Currie & Brown construction management consultants to oversee the design and execution of the refurbishment projects under a contract management framework agreement in place between the two organisations. We was called in to assess the roofs and advise on a course of action. Data driven roof condition reports from surveys were taken across the two premises. We highlighted that the roofs were beyond economical repair and needed new waterproofing and insulation- a U value of 5.00W/m2K was discovered in one roof area, against the Regulatory threshold of 0.35W/m2K and best practice 0.18W/m2K. Our solution: We advised that in the main, overlaying of the existing roof covering with CP-20 Paracoat Cold Polyurea Liquid System (warm roof) application was the most-efficient and cost-effective solution.The over-laying using the CP-20 system satisfies London Fire Brigade’s policy of preference for flame-free, with no roof replacement needed this minimised waste to landfill.Our Approved Contractor CWG Group won the contracts to undertake the upgrading, working to Langley’s detailed individual specifications for each site.At East Ham Fire Station, four main roof areas plus a separate ancillary building were addressed.LangGuard free-standing safety rail was installed around the perimeter of roofs 1 and 4.The final touch for the field roof area was provided with Paracoat Fast SF slip-inhibiting finish to agreed walkway areas.At Erith Fire Station, the refurbishment involved upgrading two roof areas including a rooftop tank room and adjoining canopy of corrugated PVC over the Station building, and a separate stores roof.

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.

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.

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

Due to the curved design of the new Everton Stadium structure, the contractors (Laing O’Rourke) were looking for M&E supports that could sit on the curved surfaces and still support the M&E installation correctly. Walraven were invited on site to discuss the Walraven Yeti solution, which is an all-in-one adjustable support foot for pitched roofs / curved surfaces. The Walraven Yeti foot was specified due to its ease of installation, adjustability and sustainable credentials.

Building contractor Eversley Building Services Ltd required a roof access ladder for emergency use in the event of a fire. However, the application constraints presented many challenges, in particular the small skylight aperture. As such, a particularly compact loft ladder was needed. Furthermore, because the loft ladder would be used during an emergency, it had to be easy-to-operate and safe for its occupants.

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

The purpose:Taylor Wimpey’s Eclipse development was the final phase of the large-scale modernisation and renewal strategy for the London Borough of Walthamstow Forest, known as The Blackhorse Lane Action Plan. Eclipse would offer affordable social and private housing via 500 homes in two six-storey apartment blocks.To help satisfy one of the Plan’s objectives- “to ensure new developments incorporate the highest levels of sustainable design and their impact on climate change is minimised”- we installed green roofs on both blocks. As it was the final development phase, space was limited; time was also an influencing factor in facilitating the tight build programme,avoiding delays, and enabling the client to deliver much-needed new homes.Our solutionTo enable fulfilment of the brief, we recommended our HM-40 Paratech Hot Melt Roofing System as the inverted waterproofing base for the green roof. A fully-bonded system, HM-40 is a robust, durable, and highly flexible monolithic, self-healing hot-melt waterproofing system for protected roofs, green roofs, terraces, and podium decks with a 40-year durability statement. In addition, it is firerated for unrestricted use when covered with a green or ballast roof.Unlike other hot melt systems that use fleeces, the Paratech system incorporates a reinforcement mesh: this allows the system to be rolled out, making waterproofing installation faster, thereby enabling the contractor to lay the top roofing layer of artificial grass and landscaped green roofs. Unfortunately, an on-site compound to store the roofing components was unavailable. We worked closely with T&T Roofing and Taylor Wimpey to ensure deliveries arrived in build sequence for immediate use, but without adversely impacting residents who had already moved into their newhomes.“The features of the flat roof system provided a seamless, issue-free roof installation, with rapid installation time causing minimal disruption. Langley’s technical team was always on hand to provide assistance when necessary, working collaboratively to guarantee a consistent and highquality installation.”

Situated in the middle of the London Borough of Hackney, Will Wyatt Court is a 511-room residential building providing student accommodation.ChallengeRoofing & façade contractor Russell Roofing Ltd were contracted to carry out refurbishment works externally on the Will Wyatt Court building - recladding and subsequently transforming the building with BTS Façades and Fabrications' Vantage® IP Interlocking Plank rainscreen system in alternating metallic colours.SolutionThe rainscreen panel used has a secret fix fastening system, which means that the majority of the fasteners are hidden - but the remaining exposed fasteners have to colour match exactly the panel in order to blend in with the building.Using Fixfast DrillFast low profile lacquered fasteners, Fixfast were able to colour match the fastener heads so Russell Roofing could install the fasteners knowing they'd match perfectly with the external panels.Fast forward to 2023 and Russell Roofing were awarded 'best refurbishment project' in the 2023 UK Façade Awards for the Will Wyatt Court refurbishment and re-cladding of the building. "Working with Fixfast at Will Wyatt Court was a great experience all round. Their unwavering commitment to providing technical support, cost-effective solutions, and exceptional customer service has not only streamlined our processes but elevated the overall success of the project."Frazer Simpson - Director at Russell Roofing Ltd

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

The Host Helix building, also known as the “Helter-Skelter,” was a unique and striking structure built in 2011 with stunning views of North London and Wembley Stadium. Over time, the building experienced general wear and tear and water began to enter the buildings’ complex structure.Polyroof Products were called in to consult with the clients and offer a seamless, encapsulated solution that could address the many unusual details associated with the building’s design.The SolutionA full survey of the roof terrace areas was conducted by the Polyroof Technical Services, after which a bespoke specification was produced for the works. The proposal document detailed a comprehensive set of recommendations for producing a seamless solution to encapsulate the problematic roof, therefore solving the issues that had arisen over the years due to its condition and age, as well as the issues associated with the original design of the pitched, curved roof.Polyroof SA Carrier Layer was then applied over the cement particle boards with Polyroof pre-formed GRP Drip Trims fixed to the external edge. For continuity and to create a uniform finish, the SA Carrier Layer was extended onto the main roof sections as a substrate for the Protec system.Any details requiring local reinforcement were treated with Protec Resin and 75mm wide Polymat 450. The curing process was allowed to take place. To accommodate structural expansion / contraction movements at appropriate details, 25mm disbondment tape was installed prior to local reinforcements.The first coat of Protec Resin and Polymat 450 was applied at a minimum coverage rate of 1.3 – 1.5Litres/m² (0.66 – 0.77m²/Litre) and was allowed to cure. To complete the system, a second coat of Protec Resin was applied at a minimum coverage rate of 0.5Litres/m² (2.0m²/Litre) and was allowed to cure.ComplexitySuch an iconic building in the local community, the client wanted to protect the original aspects of the building to the fullest extent, so the Protec system installed at the perimeter was color-matched to the original blue and grey colours. This was achieved by blending pigments until they matched the desired colors, in turn the pigment was then blended into the Protec resin before application. The survey revealed concerns about the original building designs from 2011 and the roof’s drainage system. Due to the roof’s pitch, rainwater was cascading down the curved slopes at high velocity and causing water to bounce into the building under the original capping.After many discussions between the main contractor and Polyroof, as well as the provider of the external cladding, it was agreed that the perimeter detail needed to be encapsulated with the new waterproofing system to prevent further water ingress. Fire-retardant cement particle boards were fixed to the internal and top faces of the external parapet walls, and the Polyroof SA Carrier Layer was applied over them with Polyroof pre-formed GRP Drip Trims fixed to the external edge.The Protec System was then applied to encapsulate the entire parapet detail, meaning its waterproof integrity would be covered under the Polyroof Guarantee. The curvature of the building added complexity to this process, and the contractor took great care in cutting the trims to size and fixing them to the external edge to ensure they followed the profile of the structure. Due to the building’s height, all the trims were face-fixed to prevent wind uplift.WorkmanshipIn order to improve drainage and prevent water from accumulating in hotspot areas of the roof, the contractors were instructed to install new internal curved gutter channels at the point where the roof and building met. These channels were designed to have a sufficient height and angle to effectively direct rainwater towards the outlets, preventing water from pooling on the roof. However, the installation process was made more complex due to the curved nature of the building’s architecture, which required careful measurement and customization of the gutter channels to fit the unique shape of the building.Additionally, the contractors had to consider the many joins of the gutters and how they would hold up to the elements over time as the building structure expands, contracts and moves. Extra steps were taken to ensure the gutters liquid membrane was properly sealed and secured to prevent leaks.The contractors were instructed to repair all protrusion and mansafe post details as necessary in order to allow the Protec System to be installed to a minimum height of 150mm, and to terminate it underneath a suitable weathering flange or jubilee clip. In addition, all right angles were to be reinforced with double taping. Any protrusions that were liable to significant movement was required to have disbondment i.e., bond break, tape applied to it to stop the external coating from stressing on expansion. Furthermore, all pipes were to be abraded, solvent wiped, and where necessary, primed in accordance with the Polyroof coatings manual. A flashing detail was also to be created with a weathering flange or seal.All outlets were inspected to ensure that they were functioning properly. Any outlets that were deemed unsuitable were replaced with new ones. The outlets were cleaned, prepared, and primed as necessary. The Protec system was then dressed into the outlets as far as was practical. The inspection and replacement of the outlets and the preparation of the Protec system helped to ensure that the drainage system functioned effectively.ConclusionThe refurbishment of the roof was completed within the client’s target timeframe and budget. Following a final inspection by Polyroof Technical Services, which highlighted quality workmanship of Tower Asphalt Ltd, the client received Polyroof’s trusted Accredited System Guarantee and now has the peace of mind the roof will be leak-free for decades to come.

ChallengeWork is underway to create a new theatre that will transform the existing 1932 Royal Shakespeare Theatre whilst retaining the original Art Deco and Victorian elements of the building. Due for completion during 2010, the theatre will give artists and audiences alike the best environment in which to perform and enjoy Shakespeare with improved public spaces both inside and surrounding the theatre.The challenge for the project design is to blend the key aspects of the existing buildings with the new theatre designs. Specialist roofing contractor, Varla (UK) Limited were awarded the contract to design, manufacture and install the zinc standing seam roof and wall package. Varla (UK) Limited challenged Knauf Insulation to propose a solution to meet the demanding specification for this unique project.SolutionKnauf Insulation provided detailed ongoing technical support during the design stages of the project and proposed solutions based on the results of unique three-dimensional heat loss calculations. The unique 3-D calculation support service, provided by the Technical Advisory Centre, was an integral part of the product specification process to ensure that the exact thickness recommendations were proposed in order to meet the project’s specific U-value requirements.Knauf Insulation were able to provide a solution that met all of Varla’s insulation requirements by using 160mm of Knauf Insulation FactoryClad Roll 32. This is a flexible, lightweight roll of resilient Glass Mineral Wool with exceptionally high tear strength and a thermal conductivity of just 0.032 W/mK.In addition, Knauf Insulation FactoryClad Roll 32, recommended for this project, is manufactured from Glass Mineral Wool, which is ideal for limiting the spread of fire since it holds a Euroclass A1 reaction to fire classification for non-combustibility. The product will not burn, will not give off toxic smoke nor will it suddenly ignite in a fire due to ‘flashover’. For public buildings such as this, superior fire performance is crucial.
