What flat roof work do we do in Plymstock?
Extension and kitchen roofs
Ponding against the house wall is a common reason for replacing an extension roof in Plymstock. When the deck dips near the wall or the fall runs the wrong way, water sits against the abutment and eventually gets in. A new roof with corrected falls moves the water to the gutter.
Torch-on felt roofing
Torch-on felt suits property owners in Plymstock who want a dependable, layered roof without paying the top price per square metre. With two or three bonded layers, a single small defect in one sheet need not lead to a leak, which is a real advantage on larger roofs that are hard to inspect often.
Dormer roofs
Dormer roofs in Plymstock are often replaced when the loft room below starts to show damp, particularly along the back wall or around the window head. By then the deck may be wet, so a full rebuild with new insulation is usually the better choice than patching from a ladder.

What flat roofs are typical in and around Plymstock?
In a town like Plymstock flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and lock-up garage blocks on estates. Rain and wind decide how a flat roof is detailed. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Plymstock?
Where approval is needed it goes to Plymouth City Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.
