For flat roofing work in Malmesbury, this means specification choices that reflect the actual conditions rather than generic Wiltshire averages.

Flat roofing in Malmesbury is concentrated on the 1960s–80s estate housing below the historic hilltop — particularly on the south-facing extensions that receive the strongest UV exposure. Felt failure through blistering is more common on Malmesbury's estates than in sheltered valley towns due to the elevated position and direct sun exposure. GRP replacement is the correct solution.
The medieval and Georgian town centre occasionally has flat-roofed outbuildings within the conservation area. These require careful specification — GRP is generally acceptable on non-visible rear surfaces, but visible flat roofs in the conservation area may require lead or torch-on felt to match historic character. We advise on planning requirements during the free survey.

GRP fibreglass carries a 25-year material guarantee and significantly outlasts felt. It's seamless once cured, handles thermal cycling well, and doesn't suffer the joint failures common on felt. We recommend GRP over re-felting in almost all cases.
A standard single-storey extension flat roof up to 25m² is typically completed in one day. Larger or more complex roofs may take two days. We give an accurate timeline in every quote.
Yes — garages, outbuildings and garden buildings are a regular part of our flat roofing work in Malmesbury. Same specification and 25-year guarantee as domestic extensions.
If the roof is more than 20 years old and showing active failure, replacement is almost always more cost-effective than repair. We survey and advise honestly — we won't recommend replacement if targeted repair genuinely meets the situation.
GRP fibreglass carries a 25-year material manufacturer's guarantee plus our own 10-year workmanship guarantee. EPDM carries a 20-year material guarantee. Both are provided in writing on completion.
