GRP & EPDM FLAT ROOFING
IN BRISTOL
Old-style felt flat roofs typically last 10–15 years before blistering, splitting and failing. Modern GRP fibreglass (glass reinforced polyester) and EPDM rubber roofing systems offer a far superior alternative seamless, fully weatherproof, and built to last for 25–30+ years with minimal maintenance.
Gibbs Roofing installs GRP fibreglass and EPDM flat roofing systems on house extensions, garage roofs, bay windows, dormers and outbuildings across Bristol and the surrounding area. GRP systems are applied as a single seamless coat over a plywood deck, eliminating the seams and joints where traditional felt leaks most commonly occur. EPDM rubber membranes are exceptionally durable, resistant to UV, ozone and temperature extremes, and ideal for larger flat roof areas.
We cover Clifton, Bedminster, Keynsham, Redland, Horfield, Kingswood and all Bristol postcodes within a 30-mile radius. All flat roofing quotes are free, written and no-obligation.

FLAT ROOFING QUESTIONS
Common questions about GRP fibreglass and EPDM flat roofing in Bristol.
CALL GIBBS ROOFING
07770 391115
How much does a GRP flat roof cost in Bristol?
A typical bay window GRP flat roof in Bristol starts from around £400–£700. A single-storey extension flat roof typically starts from £1,200–£2,500 depending on size and access. A garage roof starts from around £600–£1,200. We provide free, written quotes for all flat roofing work before any work begins.
How long does GRP fibreglass last compared to felt?
Traditional felt flat roofs typically last 10–15 years before blistering, splitting and failing. GRP fibreglass and EPDM rubber systems typically last 25–30+ years with minimal maintenance making them significantly more cost-effective over the long term for Bristol homeowners.
Can GRP be installed in wet or cold weather?
GRP fibreglass requires dry conditions and a minimum temperature to cure correctly. In wet or very cold Bristol weather, we may reschedule installation to ensure the system cures properly. EPDM is more flexible in cooler temperatures. We’ll always advise on the best installation window when we quote.
Do you replace the deck as part of the flat roof installation?
Yes if the existing plywood or OSB deck is wet, soft or damaged (common with failed felt roofs), we replace it as part of the installation. A sound deck is essential for the long-term performance of GRP and EPDM systems. Deck replacement will be included in your written quote if required.
