Flat & rubber roofs
Firestone EPDM rubber roofs on garages, extensions, dormers — 20-year manufacturer guarantee.
Felt roofs reach end-of-life. The seams split, water gets in, the deck rots. The modern replacement is a single-sheet EPDM rubber roof — one piece of rubber laid over the whole surface, with no central seams to fail. Firestone is the dominant brand in the UK; we're approved installers.
Typical applications: flat-roofed garages, kitchen extension roofs, dormer roofs, porches, bay window roofs. We strip the failing felt, check and replace any rotten deck timber, then bond the rubber sheet directly to the deck. Edge trims and outlets are in-keeping with the property — no DIY-ugly silver flashing edges.
20-year manufacturer warranty on the rubber itself, our 10-year workmanship guarantee on the install. Realistic lifespan is 30-50 years.
The deck underneath matters as much as the covering. If the boards have been getting wet they need replacing, and any quote that doesn't mention checking them is guessing at your expense. We lift and inspect before pricing wherever access allows, so the figure you're given accounts for the deck rather than it becoming an extra halfway through the week.
Falls and outlets are the other half of the job. A flat roof isn't flat — it needs enough fall to shift water to an outlet, and plenty of older extensions were built with almost none, so water sits in a puddle and eventually finds the one weak spot. Where that's the underlying problem we'll build the fall back in rather than laying new rubber over a roof that will simply pond again.
We fit EPDM rubber, not fibreglass. We're happy to repair a GRP roof someone else has laid, but we won't install a new one — GRP is rigid and buildings move, so it cracks at the joints and upstands as the structure flexes. Rubber stretches with it.
