EPDM Rubber Roofing in Swindon
Local roofers for repairs, new roofs & flat roofing. Free surveys, fixed written quotes, tidy workmanship.
Swindon Roofing Company installs EPDM rubber roofs across Swindon — single sheets of synthetic rubber, cut to your roof and bonded down with no joins anywhere water could find. For garages, extensions and dormers, EPDM has become the default modern answer: 20–30 year lifespans at a price closer to felt than to fibreglass.
One membrane, fully adhered, with purpose-made trims at every edge — the simplicity is the reliability.
Why EPDM took over flat roofing
One piece, no seams
Domestic roofs are covered by a single factory sheet — the joins that fail on felt roofs simply don't exist.
Elastic for decades
EPDM stretches over 300% and shrugs off UV, frost and thermal movement — the things that crack and blister bitumen.
Best value lifespan
Materials cost more than felt, less than GRP — and the 20–30 year life makes it the cheapest per year of dry ceiling.
Repairable in minutes
The rare puncture (an aerial dropped, a slate from next door) patches permanently — no full-surface drama.

The details that make EPDM last
The membrane never fails; edges and preparation occasionally do. Our installs go onto a clean, dry, screwed-down deck — new OSB where the old boards have been wet — with water-based deck adhesive across the field, contact adhesive at perimeters, and proprietary trims at gutters, kerbs and upstands. On living-space roofs we default to a warm-roof build-up: insulation above the deck, membrane above that, condensation risk designed out and building regs satisfied in the same move.
That's the whole recipe. EPDM is the least dramatic product in roofing, which is exactly what you want above a kitchen extension.
