GRP fibreglass and EPDM flat roofing specialists in Corsham. Experienced with conservation area planning requirements and the specific drainage challenges of rear extensions on period properties. Free no-obligation quotes.
Corsham's conservation area and Bath stone properties retain moisture differently to modern brick — damp penetration from failed mortar is faster on porous limestone. For flat roofing work in Corsham, this means specification choices that reflect the actual conditions rather than generic Wiltshire averages.
Victorian and Edwardian terraces on the High Street and Lacock Road dominate the repair profile. We are 3 miles west from Corsham — 8 minutes — with no travel surcharge and same local knowledge that applies to every property type in this area.

Flat roofing in Corsham's conservation area requires some additional thought around planning. Single-storey rear extensions on listed or conservation area properties may need prior approval — particularly if the extension itself didn't have consent, or if the proposed roofing material changes the visible roof profile. We advise on planning implications during the free survey before any specification is agreed.
The most common flat roofing call from Corsham is rear extension flat roofs on Victorian and Edwardian properties — typically felt roofs installed 20–40 years ago during extension work, now reaching or beyond end of life. We replace these in GRP fibreglass as standard, which carries a 25-year material guarantee and is the most durable option available. Drainage correction is included on every installation — ponding extensions are a common discovery during survey.
"Felt flat roof on Victorian terrace extension failing after 25 years. Replaced with GRP — done in a day, excellent finish on the upstands. Also corrected the drainage fall that was causing ponding. No issues through two winters."
"New GRP roof on rear single-storey extension. Permitted development — they confirmed planning status during the survey. Clean installation, watertight from day one."
"Large L-shaped flat roof on a converted outbuilding done in EPDM. Neat upstand detailing, good drainage. Far better than the felt it replaced."
Like-for-like flat roof replacement doesn't normally require consent. New flat roof extensions or changes to roof profile on listed or conservation area properties may need prior approval. We advise on planning status during the free survey — don't start work without checking.
GRP fibreglass is our first recommendation — seamless, 25-year material guarantee, and excellent performance on small to medium domestic extensions. EPDM is better suited to very large or complex roof shapes. We advise based on your specific roof geometry.
