Flat Roofing in Hailsham
Flat roofing in Hailsham requires the right system for the local conditions. We install GRP fibreglass and EPDM rubber — both suitable for Hailsham's climate. We do not install felt flat roofs: inland frost-pocket location — freeze-thaw cycles are more severe here than on the coast, accelerating mortar and pointing failures makes felt an unsuitable choice for long-term performance in this area.
The Victorian town centre with 1960s–80s residential estates on the western and northern fringes in Hailsham 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 Hailsham 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 Hailsham 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.

Garage flat roofs — full replacement in GRP or EPDM. Rear extension flat roofs — replacement or overlay where the deck is sound.

Why GRP Is the Right Specification for Hailsham
Felt flat roofing has a 10–15 year lifespan under East Sussex conditions. GRP fibreglass lasts 25–50 years with no maintenance requirement and carries a manufacturer-backed product guarantee. We do not install felt on any property in Hailsham — 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 Hailsham Properties
Falls of 1:80 minimum are required across any flat roof surface. In practice we target 1:60 on new installations in Hailsham to account for settlement. Outlets must be sized for the catchment area — undersized outlets are the most common cause of ponding on existing Hailsham flat roofs. We assess drainage as part of every survey and specify correctly from the start.
Deck Inspection Before Your Hailsham Flat Roof
Before laying any new flat roof covering in Hailsham, we expose and inspect the deck. Soft spots, delaminated plywood and degraded timber all need addressing before the membrane goes down. On most Hailsham 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.
