"Garage flat roof had been leaking for a year — patched twice by someone else, kept coming back. Had it done properly in GRP and it's been solid through two winters since. Should have done it first time."
"Single-storey kitchen extension flat roof — they installed EPDM and the difference from the old felt is night and day. No puddling, no leaks. Very professional team."
"Full GRP re-roof on the back addition. Completed in one day, no mess, and they showed me the new drainage detail so I know exactly how it works. Excellent job."
The Hull Valley's combination of persistent moisture, significant annual rainfall and pronounced freeze-thaw cycling makes East Yorkshire one of the most demanding flat roofing environments in England. Traditional felt flat roofing — three-layer built-up felt on a cold deck — has a design life of 10–15 years in these conditions. In sheltered or drier areas that figure might stretch. In Beverley, with the ground-level moisture from the Hull Valley and winter temperatures that cause repeated expansion and contraction, 10 years is optimistic if the initial installation was budget specification.
GRP fibreglass and EPDM rubber are the appropriate systems for this climate — both engineered specifically to handle the movement, moisture and temperature cycling that destroys traditional felt. Flat roofs on single-storey rear extensions are particularly common in Beverley's 1960s and 70s stock in the Grovehill, Swinemoor and Woodmansey Road areas. Many of these original flat roofs are now 40–50 years old and well past any realistic repair window.
If the felt is cracked, blistered or showing through-splits in multiple areas, or if there is moisture in the deck below the membrane, repair is papering over the inevitable. A GRP or EPDM replacement costs more upfront but needs nothing spent on it for 25+ years. We survey every flat roof before quoting and will tell you honestly whether repair is viable.

A standard single-storey extension or garage flat roof in Beverley typically costs £800–£2,500 depending on size and material choice. GRP fibreglass systems run slightly more than EPDM rubber but have a longer service life. We'll survey the existing roof and recommend the right system for your situation. Full, itemised quotes with no obligation.
A quality GRP (fibreglass) flat roof correctly installed will last 25–40 years in East Yorkshire conditions. EPDM rubber roofing has a similar life expectancy. Traditional felt flat roofs typically last 10–15 years. Given the freeze-thaw cycle and persistent moisture in the Hull Valley, the higher-spec systems represent significantly better long-term value.
The Hull Valley's low-lying terrain creates persistent humidity and moisture-laden air, which accelerates deterioration of traditional felt. Winter freeze-thaw cycles repeatedly stress any small cracks or joints. The combination is particularly hard on cheap felt systems. GRP and EPDM are specifically engineered to handle this and are the right choices for the East Yorkshire climate.
If the existing deck is sound and the felt membrane is only failing in specific areas, a repair is often possible. We'll cut back to good material, clean and dry the substrate, and apply compatible repair compound. However, if the felt is generally degraded or the deck has moisture damage, a full replacement is more economical. We'll assess and give you an honest recommendation.
Yes, and in some cases it's the most cost-effective long-term solution for a persistently problematic flat roof. A low-pitched tiled or slated addition to a single-storey extension eliminates the flat roof maintenance cycle entirely. Planning permission may be required depending on the size of the change and the property's location. We can assess and advise — call 0148 290 8437.
For a standard single-storey extension or garage, a GRP or EPDM replacement is typically completed in one day with minimal disruption. The internal space below is inaccessible for that day. We protect the surrounding area and leave the site clean. Most homeowners are surprised by how quick and clean the process is compared to a pitched roof replacement.
Very little. An annual check of the drainage outlets — clearing any debris from the outlet and checking the surrounding membrane hasn't lifted — takes ten minutes. A visual inspection of the surface and any upstand edges every two or three years is good practice. Neither GRP nor EPDM requires painting, coating or chemical treatment during its service life.
No call-out fees. No obligation. Just an honest quote from a local Beverley roofer who turns up when they say they will.
