GRP fibreglass and EPDM rubber flat roofing for extensions, garages and bungalows. Installed with proper drainage falls and edge detailing. Flat roofing from £800. Free surveys, 25-year system guarantees.
Seamless one-piece system over 18mm WBP ply deck. 25-year lifespan, no joints to fail.
Single-ply rubber membrane for larger areas. 30–50 year lifespan, superior thermal flexibility.
Full strip of existing felt, new ply deck where required, new membrane system.
18mm WBP plywood deck with correctly graded falls to prevent water ponding.
Correct outlet positioning and sizing — undersized drainage is the leading cause of early flat roof failure.
Rigid insulation board below the membrane where thermal performance needs improving.
Shildon's housing is predominantly Victorian railway worker terraces around Soho Street and the town centre with Welsh slate roofs; post-war semis on the estate fringes with concrete interlocking tile. Knowing the specific roof types and their failure patterns is the difference between a roofer who diagnoses correctly first time and one who keeps coming back.
Elevated exposed position with significant westerly weather — harder on mortar bedding and flashings than valley towns below. This directly affects how quickly specific problems develop and which repair approaches last longest.
Lead flashing failure and mortar ridge deterioration on Victorian terraces; nail sickness across 1960s–70s post-war estates; west-facing slopes losing tiles in storm events. We cover Shildon regularly and carry the most common materials on the vehicle.
Flat roofing from £800. Free surveys, 25-year system guarantees. No call-out fee.
“Called after storm damaged our Victorian terrace on Soho Street. Slates replaced with matching reclaimed slate. Couldn't tell where the new ones were.”
“Lead valley on our old terrace had been slowly failing for years. Found and fixed properly — no more water in the back bedroom.”
“Ridge repointing and new dry-fix system fitted in one day. No mess, scaffolding down same week. Exactly as quoted.”

The primary cause of premature flat roof failure in Shildon is inadequate drainage. Elevated exposed position with significant westerly weather — harder on mortar bedding and flashings than valley towns at lower elevation. A flat roof that ponded water in summer can become a freeze-thaw problem in winter as standing water expands and contracts around the membrane edge. Every flat roof we install in Shildon is built with a minimum fall of 1:80 to the outlet, and we verify the outlet capacity is adequate for the roof area and the local rainfall load.
Before installing a new flat roof membrane on any property in Shildon, we inspect the existing ply deck condition. Decks that have been under a failing membrane for years may have absorbed moisture and become structurally compromised. A new membrane installed over a soft or delaminating deck will fail early regardless of membrane quality. We include deck inspection in every survey and price deck replacement separately where required — never fold it into the membrane cost and hope it holds.
Shildon's climate — elevated exposed position with significant westerly weather — harder on mortar bedding and flashings than valley towns at lower elevation — makes the choice of flat roof system particularly important. Traditional felt systems have multiple lap joints that fail in wet, frost-prone conditions. GRP is a seamless single-layer system with no joints to fail. EPDM is a single-ply rubber membrane that remains flexible at extreme cold. Both systems significantly outperform felt in the conditions typical of Shildon and the broader County Durham / North Yorkshire climate.
GRP is a rigid seamless system good for most extension sizes up to around 40m². EPDM is a flexible rubber membrane better suited to larger areas or roofs with complex geometry. Both outperform any felt system significantly.
If the roof is under 15 years old and one area has failed, a targeted repair is often viable. If it's original felt from the 1970s or 1980s, the whole membrane has degraded — patching one area when the rest is about to fail is a false economy.
