Everything You Get with StoneRidge Roofing
Canterbury's 1960s and 1970s flat roofs
A large share of the flat roofing we do in Canterbury is replacing the same thing: a felt roof put on a rear extension, a garage or a dormer forty or fifty years ago. They were built when three layer felt was the standard answer, they have been patched more than once, and most are now past the point where patching is worth the money. If yours is one of them the realistic options are EPDM rubber or GRP fibreglass, and which one suits depends on the shape, the upstands and how many junctions it has rather than on which is better in the abstract. We price both so you can compare rather than take our word for it. Ponding water is the thing to watch for: if it is still sitting there two days after rain, the falls are wrong and recovering the roof without correcting them just buys you a few years.
Modern Flat Roofing Solutions for Kent Properties
Flat roofs are a practical and versatile choice for extensions, garages, dormers, porches, and balconies on properties throughout Canterbury and Kent. However, the performance of a flat roof depends entirely on the quality of the materials used and the expertise of the installation. StoneRidge Roofing installs high-performance flat roofing systems that are built to withstand Kent's variable climate, from heavy winter rainfall to summer heat. We specialise in GRP (glass reinforced plastic) fibreglass, EPDM rubber membrane, and modern felt systems, selecting the best option for each project based on the structure, budget, and intended use. Every flat roof we install across Canterbury, Margate, Faversham, Deal, and Folkestone is designed with correct falls to ensure efficient water drainage and prevent ponding.
GRP Fibreglass Flat Roofing
GRP fibreglass roofing is the gold standard for modern flat roof installations in Canterbury and Kent. This system uses layers of glass fibre matting and resin to create a single, seamless, waterproof surface with no joints or seams where water can penetrate. Once cured, a GRP roof forms an incredibly strong, rigid surface that can be walked on and is virtually maintenance-free. GRP roofs installed by StoneRidge Roofing typically last 30 years or more with minimal upkeep. The system is ideal for extensions, garage roofs, dormer tops, and bay window roofs. We apply a professional top coat in a colour of your choice, and the finish provides excellent UV resistance to prevent cracking or degradation in sunlight.
EPDM Rubber Roofing
EPDM (ethylene propylene diene monomer) rubber roofing is another excellent flat roofing option available from StoneRidge Roofing. This synthetic rubber membrane is supplied in large sheets that are bonded to the roof deck, minimising the number of joints. EPDM is highly flexible, which makes it resistant to cracking even in extreme temperatures, and it has an expected lifespan of 25 to 30 years. It is a popular choice for larger flat roof areas on properties in Canterbury and across Kent because the sheets can cover wide spans without seams. EPDM is lightweight, quick to install, and provides outstanding waterproofing performance. StoneRidge Roofing uses premium-grade EPDM membranes with full manufacturer warranties.
Flat Roof Maintenance and Inspections
Regular maintenance extends the life of any flat roof on properties in Canterbury and Kent. StoneRidge Roofing recommends having your flat roof inspected at least once a year, particularly after winter storms or periods of heavy rain. Common issues we check for include standing water caused by inadequate drainage falls, cracks or blisters in felt or GRP surfaces, lifted edges or seams on rubber membranes, blocked outlets and gutters, and vegetation growth. We provide flat roof inspection services and can carry out preventative maintenance to address small problems before they develop into expensive repairs. For older felt roofs that are reaching the end of their life, we can overlay or strip and replace with a modern GRP or EPDM system that will last decades longer.
