Tony & Ara’s Project, as featured on Channel 4’s Grand Designs.

By Louis Wright • November 7, 2024
At the beginning of October 2019 we were approached by Tony and Ara to ask if we would be interested to assist with a quotation to work with them on their new build project in the village of Stoke Row, Henley on Thames, Oxfordshire and were made aware that the project would be featured on the Grand Designs television show. Tony explained that they were at the stage of the build where they required waterproofing to the main roof as soon as possible due to being let down by their chosen roofer and the fact that the rain was relentless and heavy, making progress impossible.

Tony explained that they were at the stage of the build where they required waterproofing to the main roof as soon as possible due to being let down by their chosen roofer and the fact that the rain was relentless and heavy, making progress impossible. We visited site to carry out an initial survey and following discussions proposed the Triflex ProTect/ProDetail cold applied PMMA resin roofing system & Triflex ProTerra Quartz balcony product due to the complexity of the roof, balconies and fascia bands. The benefits of using the Triflex products was the extremely quick curing times of the PMMA resins and the fact that it is a single layer product therefore greatly reducing installation times and most importantly that the waterproofing forms a completely seamless waterproofing solution. - Read about the full project on our website. A few kind words from Tony and Ara,

A few kind words from Tony and Ara, "Fortunately, we found Steve Crumpler and his team at Advanced Roofing Solutions Ltd, who provided us with the perfect solution. The quality of their product, TriFlex, has been outstanding, giving us a durable and completely waterproof roof that we trust for the long term. What truly sets Steve and his team apart, though, was their professionalism and the help they provided in getting us out of such a difficult situation. They worked quickly and efficiently, delivering first-class workmanship and ensuring that every detail was completed to the highest standard. Looking back, I wish I had done more thorough research from the beginning and chosen Advanced Roofing from the outset. However, I am incredibly grateful that they came through for us when we needed them the most. I wholeheartedly recommend Steve and his team to anyone..." Tony and Ara
Another property protected from the British weather!

A Topseal HD Warmroof System Installed at Northfield Court We have recently completed the refurbishment of the flat roof coverings at Northfield Court, Henley on Thames where our role was principal contractor. The project involved the erection of a ‘tin hat’ temporary roof scaffold to ensure that there was no rainwater ingress into the occupied flats during the course of works. The installation involved the complete removal of the original roof coverings which included a saturated woodwool slab. Structural alterations were carried out including the reinforcement of the existing timber joists and the cutting out and installation of an roof access hatch. An 18mm sub-deck board was installed with Visqueen vapour control layer – 140mm of rigid thermal insulation – structural tongue and grooved roof deck – Topseal HD (BBA approved) GRP flat roof covering which will provide the owners with a seamless flat roof covering that is covered by a 30 year watertightness guarantee. The project was registered by us through the NFRC Competent Person Scheme to confirm compliance with current building regulations and the certificates of compliance were provided.

Leaking off the shelf GRP fibreglass roof covering - fixed by Advanced Roofing Solutions. Our customers had an off the shelf, non-BBA approved GRP fibreglass roof covering installed onto their new extension by poorly trained installers and had been suffering leaks ever since. Following inspection we discovered a number of faults including pinholes and areas where the fibreglass had delaminated from the roof deck boards and topcoat was flaking. The project involved removing the existing GRP fibreglass roof covering, roof deck boards, inspection of the thermal insulation layer and checking that a vapour control layer and sub-deck was present. Our installers then carefully re-constructed the roof, installing a new tongue and grooved OSB3 roof deck and installed the new Topseal HD GRP fibreglass roof covering. Topseal HD is a BBA approved and certified GRP roof covering that forms a completely seamless waterproofing system that is guaranteed for a period of 30 years. The new roof coverings are now guaranteed and have been registered through the NFRC Competent Person scheme to confirm compliance to building regulations. #RoofingSolution #RoofingContractor #RoofRepair #RoofInstallation #HomeImprovement #RoofMaintenance #RoofDesign #RoofingSystem #RoofingSolutions #GRPRoofing #FibreglassRoofing #LiquidRoofing #GreenRoofing #FlatRoofing #BalconyWaterproofing #WalkwayWaterproofing #CommercialFlatRoofing

Eyre Court is a prestigious residential block in London’s St Johns Wood and is located opposite the Finchley Road entrance of St Johns Wood underground station. Advanced Roofing Solutions were contracted as principal contractor by Trust Premier Property Management to prepare and overlay 2200m² of asphalt roof with the Triflex Protect, cold applied PMMA resin roofing system which forms a completely seamless and elastic waterproof membrane that can withstand maintenance foot traffic and is covered by a 25 year guarantee. The roof at Eyre Court is a mansard design with outer slate tile faces that discharge rainwater into a large parapet gutter at the bottom with a flat roof on top. The parapet gutter runs along the entire perimeter of the front and both side elevations with a total area of 500m² and was overlaid with the Triflex ProDetail cold-applied PMMA resin detailing system and is now covered by a 10 year guarantee. The installation was complicated by the sheer amount of heating pipes and penetrations on the roof however, our installers worked meticulously and delivered a superb, fully guaranteed roofing solution that will perform for many years and has the added benefit of being able to be directly overlaid with Triflex waterproofing at any point in the future. This project was specified by Triflex UK and monitored throughout the course of works by Triflex UK field technicians. #RoofingSolution #RoofingContractor #RoofRepair #RoofInstallation #HomeImprovement #RoofMaintenance #RoofDesign #RoofingSystem #RoofingSolutions #GRPRoofing #FibreglassRoofing #LiquidRoofing #GreenRoofing #FlatRoofing #BalconyWaterproofing #WalkwayWaterproofing #CommercialFlatRoofing
