Dormer Bungalow Roofing in Nelson

Dormer Bungalow roofs in Nelson

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.

Nelson context: Long terraces of two-up-two-down millworker housing, plus larger end-of-terrace properties on Manchester Road. Many roofs share continuous valleys and party-wall chimneys. Sat in the lee of Pendle Hill — strong wind funnelling, heavy rainfall and frequent winter ice loading on north-facing slopes.

What fails on a Dormer Bungalow in Nelson

• 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.
