Flat Roofing in Old Town
Flat roofing in Old Town requires the right system for the local conditions. We install GRP fibreglass and EPDM rubber — both suitable for Old Town's climate. We do not install felt flat roofs: elevated above the town centre with some South Downs wind exposure; less direct salt loading than the seafront but still coastal climate influence; code 4 lead standard throughout makes felt an unsuitable choice for long-term performance in this area.
The historic core around St Mary's Church with a mix of Victorian, Edwardian and some pre-Victorian properties; conservation area designation applies to the historic streets in Old Town includes a significant number of properties with flat-roofed rear extensions and garages, many of which were built in the 1960s–80s and are now at or past the end of their original design life. If you have a flat roof in Old Town that is more than 15 years old and has not been replaced, it is worth having it assessed.
GRP fibreglass is our standard specification for Old Town flat roofs — it is seamless, UV-stable, and carries a 25-year product guarantee. EPDM rubber is an alternative for very large flat roofs where GRP installation would be impractical. We survey each job individually and recommend the right system for your roof's size, drainage arrangement and condition.

We do not install felt on any property in Old Town — the long-term cost comparison does not support it. EPDM rubber is an alternative for very large areas; GRP is our standard for garages and extensions.
Flat Roof Drainage for Old Town Properties
Falls of 1:80 minimum are required across any flat roof surface. In practice we target 1:60 on new installations in Old Town to account for settlement. Outlets must be sized for the catchment area — undersized outlets are the most common cause of ponding on existing Old Town flat roofs. We assess drainage as part of every survey and specify correctly from the start.
Deck Inspection Before Your Old Town Flat Roof
Before laying any new flat roof covering in Old Town, we expose and inspect the deck. Soft spots, delaminated plywood and degraded timber all need addressing before the membrane goes down. On most Old Town re-cover jobs we find at least some deck deterioration — we will not lay new GRP over a compromised deck. Deck repair is quoted transparently as part of the full job.
