Flat roof extensions on Tiverton’s post-war and 1970s housing are a frequent maintenance item. The combination of Exe Valley rainfall and the age of original felt coverings means many of these roofs are at or past end of life. We install GRP and EPDM flat roofing across Tiverton with 25-year material durability and a 10-year workmanship guarantee. Call 01392 759 295.
The majority of flat roof calls we receive from Tiverton come from the Exe Vale and Westexe estate areas where rear extensions were added to post-war semis in the 1970s and 80s. Original felt coverings on these extensions are now 30–40 years old and frequently on their second layer. When a flat roof has been re-felted once, the third covering should be GRP — the deck condition is usually such that starting fresh with a modern system is better value.
Tiverton’s elevated position and higher rainfall means we specify slightly enhanced drainage details on flat roofs in the town compared to more sheltered locations. Fall calculations and outlet positioning are critical on a roof that handles more water per year than the national average. We carry out a drainage assessment on every Tiverton flat roof survey.
The majority of flat roof work we carry out in Tiverton is on rear extensions added to Exe Vale and Westexe post-war semis in the 1970s and 1980s. These extensions were built quickly and cheaply, and their flat roofs have typically been re-felted at least once. A third felt covering on a 40-year-old deck is not the right answer — the deck condition after two cycles of felt failure and repair is usually such that a new GRP system on repaired or replaced decking provides a better 25-year outcome. We assess and advise honestly at the survey stage.
Both GRP fibreglass and EPDM rubber flat roofing are appropriate for Tiverton’s climate. GRP is our first recommendation where access for application is straightforward — its fully bonded surface and rigid finish make it the most durable option and the easiest to inspect for damage. EPDM is preferable on irregular shapes, around complex penetrations, and on larger areas where GRP application would be technically difficult. We specify on a property-by-property basis and explain the reasons for our recommendation at the survey stage.
Devon winters are wet rather than cold, but the freeze-thaw events that do occur create specific risks for flat roof coverings. Standing water on a flat roof that freezes overnight and expands can stress membrane seams and perimeter details. GRP eliminates this risk through its seamless construction. EPDM handles freeze-thaw well through its elasticity. Both materials are significantly more durable in Tiverton’s winter conditions than traditional felt, which develops stress fractures at laps under repeated temperature cycling.

“Flat roof on our 1980s extension in Westexe. Fast, professional, looks clean.”
“EPDM on our garage. They checked the deck condition first. Good honest advice.”
GRP flat roofing from £900–£4,000 depending on size. Free survey and quote. Call 01392 759 295.
If your flat roof has been re-felted once already, GRP is the better choice. The deck condition after two felt cycles usually warrants a fresh start with a modern system.
Yes — we calculate falls and outlet positioning for Tiverton’s actual rainfall load, which is higher than the national average due to the valley position.
A standard rear extension flat roof is typically completed in a single day.
