What flat roof work do we do in Devizes?
Flat roof repairs
Older flat roofs in Devizes, as elsewhere, are often covered in felt that has lost its chippings and dried out. One leak on a roof like that is a warning sign. We repair it, check the rest of the covering and tell you honestly whether replacement belongs in next year's budget.
Torch-on felt roofing
Torch-on is a good fit in Devizes when the budget matters but quality cannot slip. Modern polyester-reinforced membranes typically last 15 to 25 years, high-performance systems longer, and manufacturer material guarantees are available on many specified systems, registered where the system allows.
Commercial flat roofing
When a roof over heated space in Devizes is replaced, insulation rules usually apply. We design the warm-roof build-up towards the required standard where that is feasible and handle building control where it is needed, so the work is signed off properly and the building is better insulated afterwards.

What flat roofs are typical in and around Devizes?
In a town like Devizes flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions and bungalows with flat-roofed side extensions and dormers. Local weather shapes the specification. 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 Devizes?
Where approval is needed it goes to Wiltshire 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.
