Wokingham Roofing Company installs EPDM rubber roofing on extensions, garages, porches and dormers throughout Wokingham. EPDM is a synthetic rubber membrane supplied in sheets big enough to cover most domestic flat roofs in one piece — and a flat roof with no seams is a flat roof with nowhere obvious to leak.
It's the system we fit most, for a plain reason: on a simple rectangular roof nothing else matches its combination of lifespan, price and low fuss. Manufacturers such as Firestone quote a design life of 50 years for RubberCover membranes, and the material shrugs off UV, frost and standing water that would destroy felt.
How an EPDM roof goes together
One sheet, fully bonded
The membrane is cut oversized, relaxed on the roof, then bonded to the deck with water-based and contact adhesives. No flames, no hot bitumen — relevant if the roof sits under bedroom windows.
Purpose-made trims
Edges finish into uPVC kerb and drip trims rather than dressed-over metal. It's the detail that makes an EPDM roof look factory-made instead of site-improvised.
Cut-in upstands and outlets
Pipes, rooflights and wall junctions get moulded corners and cover strips from the same system — the failure points on old felt roofs become the strongest details.
Warm roof option
Rigid PIR insulation beneath the membrane brings habitable extensions in line with Building Regulations Part L and stops winter condensation under the deck.

Why the 50-year claim is credible
EPDM has been on commercial roofs since the 1960s, so its ageing behaviour isn't a projection — there are sixty-year-old installations still in service. The material stays flexible from -40°C to +120°C, doesn't become brittle with UV exposure the way bitumen does, and its failure modes are almost entirely at details rather than in the sheet itself. That's why we spend the time on trims, corners and upstands: get those right and the membrane simply sits there for decades.
The practical caveat is foot traffic. EPDM tolerates maintenance access fine, but a roof terrace or balcony that gets regular use is better served by GRP with a non-slip topcoat.
