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.
Richmond's housing stock is predominantly Georgian and Victorian town centre properties with natural slate, clay plain tile and stone flag roofs; stone-built terraces and cottages throughout; rural farmhouses in the surrounding Swaledale and Richmondshire countryside. Knowing the specific roof types and their failure patterns is what separates a knowledgeable local roofer from a national firm that sends whoever's nearest.
North Yorkshire Dales edge location with significant westerly and north-westerly exposure. Higher altitude than the Tees Valley creates more frost days and stronger winds. The Swale Valley provides some local shelter for town centre properties. This directly affects how quickly specific problems develop and which repair approaches last longest in local conditions.
Natural slate delamination and nail failure on period properties; mortar ridge failure on exposed pitches; lead flashing and valley deterioration on historic buildings; stone tile roofs on rural Dales properties requiring specialist knowledge. We attend these jobs regularly across Richmond and carry the most common materials on the vehicle.
Flat roofing from £800. Free surveys, 25-year system guarantees. No call-out fee.

The primary cause of premature flat roof failure in Richmond is inadequate drainage. North yorkshire dales edge with significant westerly and north-westerly exposure — higher altitude than the tees valley creates more frost days and stronger winds than valley-floor properties. 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 Richmond 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 Richmond, 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.
Richmond's climate — north yorkshire dales edge with significant westerly and north-westerly exposure — higher altitude than the tees valley creates more frost days and stronger winds than valley-floor properties — 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 Richmond and the broader County Durham / North Yorkshire climate.
GRP is a rigid seamless system ideal for most extensions up to around 40m². EPDM is a flexible rubber membrane better for larger areas or complex geometry. Both significantly outperform any felt system.
If the roof is under 15 years old and one area has failed, a targeted repair is often viable. Original felt from the 1970s or 1980s has degraded across the whole surface — patching one area is a false economy.
