Dormer Bungalow Roofing in Preston

Dormer Bungalow roofs in Preston

Bungalow that's had a loft conversion added, leaving flat-roofed dormers projecting from the main pitched roof. Common across Lancashire suburbs from the 1980s onwards. Dormer cheeks and the dormer / main-roof junction are the headline failure points.

Typical roof construction: Concrete or clay tile main roof, with flat felt or (modern) EPDM dormer roofs and lead-soakered cheek abutments.

Preston context: Wide spread — Victorian and Edwardian terraces around Deepdale and Frenchwood, large detached homes in Fulwood, and significant commercial/industrial roofing demand around Walton Summit and Riversway. Sheltered urban environment, but the Ribble corridor channels weather through Penwortham and Ashton — surface water and gutter overload are recurring issues.

What fails on a Dormer Bungalow in Preston

• Failed felt on flat dormer roofs — usually the first thing that leaks 15–20 years post-conversion
• Cracked lead soakers where the dormer cheek meets the main pitched roof
• Tile slippage immediately around the dormer where the original re-tiling was rushed
• Condensation inside the dormer because the conversion didn't add adequate ventilation

Typical job

Strip the old dormer felt, install EPDM with fully welded upstands, and re-dress the cheek soakers in code 4 lead.
