Flat roofing demand in Stratford-upon-Avon is driven mainly by the town’s large stock of extended 1930s and post-war semis. Areas like Shottery, Bishopton and parts of the Alcester Road corridor have a high density of rear single-storey extensions built between the 1970s and 1990s, most of which had three-layer felt roofs that are now well past their expected lifespan. Replacing these with a modern GRP fibreglass system is one of the most reliable home improvement jobs a Stratford homeowner can undertake.
We specify GRP fibreglass as our default flat roofing material for Stratford properties, particularly for those within the Avon Valley moisture belt. The town’s position in the river basin creates persistently higher humidity than surrounding high ground, which accelerates the degradation of traditional felt. GRP is seamless, resistant to moss establishment, and backed by a 25-year manufacturer guarantee. For larger areas or budget-conscious installations we offer EPDM rubber, which performs well in the Midlands climate and carries a 20-year guarantee.

Free quotes, no call-out fees, honest advice.
“The felt roof on our 1980s extension had been leaking for two years — two previous roofers patched it and it came back both times. These lads stripped it off, installed GRP and it has been completely dry through two full Warwickshire winters.”
“Double garage re-roofed in GRP. They checked the falls first, raised the low corner by 25mm and now water drains properly for the first time in years. Wish we had done it ten years ago.”
“New extension on the back of a 1930s semi in Tiddington. Specified GRP from the start on their recommendation. Clean, fast installation and the finish around the perimeter is immaculate.”
GRP (fibreglass) is seamless, watertight and highly resistant to the elevated humidity of the Avon Valley floor. Properties within half a mile of the river experience significantly more moss growth and moisture exposure than those on higher ground. GRP is the most durable option in these conditions and carries a 25-year manufacturer guarantee. Felt deteriorates faster in this environment and is no longer the material we recommend for new flat roofs in the Stratford riverside area.
A single-storey extension flat roof in Stratford typically costs between £1,200 and £3,500 in GRP fibreglass. Garage flat roofs are usually £800 to £2,000. EPDM rubber is a slightly lower-cost alternative for larger areas. We provide free quotes for all flat roofing work.
A properly installed GRP flat roof should last 25 to 30 years with minimal maintenance. EPDM rubber typically lasts 20 to 25 years. Traditional felt is 10 to 15 years at best and shorter in the Avon Valley microclimate. Annual drainage checks are recommended for all flat roofs in Stratford due to autumn leaf fall.
Yes. Single-storey rear extensions are the most common flat roof job we do across Stratford and the surrounding villages. We work on new builds, replacement installations and repairs, and advise on drainage fall to prevent water ponding.
No call-out fees. No obligation. Just an honest quote from a local Stratford roofer who turns up when they say they will.
