When it comes to flat roofing in Ashford — the expanding market and rail town on the Great Stour — and with housing that is largely Victorian terraces, inter-war semis and large modern estates, ageing felt flat roofs cracked and ponding across mixed stock is the typical call.
We keep it honest — recover the flat roof in GRP fibreglass or EPDM rubber with proper falls to the outlet, repairing the deck if needed, with GRP or EPDM, far longer-lasting than the felt it replaces — a free Ashford survey, a fixed written quote and no call-out fee.
Most Ashford flat roofs are low and reached from a tower; scaffold only where the flat roof is at height or wraps a two-storey return. Scaffold is specified for: first-floor or wrap-around flat roofs, or where edge protection is needed - always itemised in your written quote, never a hidden extra, and we arrange it.
Ashford’s high-street and terraced properties often have narrow frontages and rear-access-only roofs, so scaffold and permits take a few working days. Pavement scaffold and skip permits go through Ashford Borough Council; allow a few working days on streets like Ashford high street, Ashford’s older terraces where space is tight.
Flat roofs on Ashford extensions, garages and dormers are where felt fails first. We fit GRP fibreglass or EPDM rubber with a 25-year guarantee rather than short-life felt. Ashford's character as a inland town — with Victorian railway-town terraces near the station, sprawling post-war and 1970s estates at Stanhope and Bockhampton, and large modern developments at Repton Park and Chilmington — means no two flat roofing jobs here are quite the same, and we quote each on its own merits.
Local knowledge counts in Ashford because The 1970s Stanhope and Bockhampton estates are the volume work — nail sickness on concrete interlocking tile is now widespread. Modern estate homes at Repton Park see early failures of thin-profile dry-verge and ridge systems. From Beaver Road, Hythe Road, Kennington Road, Repton Avenue outward, the same pattern repeats, and our flat roofing method accounts for it. 1970s estate concrete-tile roofs commonly need full re-fix; modern estates see dry-verge failures.
A standard rear extension flat roof of 15–25m² in GRP fibreglass costs £1,400–£2,800 in Ashford. Garage flat roofs typically run £1,200–£2,200 depending on size. EPDM rubber is a slightly lower-cost alternative with a similar guarantee period. Free survey and fixed-price quote always provided.
GRP fibreglass is our standard recommendation for Ashford extensions — it is seamless, highly durable, and carries a 25-year manufacturer guarantee. EPDM is a good alternative for simple rectangular roofs. We do not install felt flat roofing as a replacement system — its design life is too short to represent good value.
Yes. We work on new build extensions and provide the waterproofing specification and certification required by building control. GRP warm roof construction is the standard for most architect-specified extensions.
GRP carries a 25-year material guarantee. Our workmanship is guaranteed for 10 years. Correctly installed GRP regularly exceeds its guarantee period — it is the most durable flat roofing system available for residential properties.
