Flat Roofing in Langney
Flat roofing in Langney requires the right system for the local conditions. We install GRP fibreglass and EPDM rubber — both suitable for Langney's climate. We do not install felt flat roofs: slightly exposed to north-east winds from the coast; less salt loading than seafront areas; frost episodes moderate; good drainage generally but valley blockages in autumn are common makes felt an unsuitable choice for long-term performance in this area.
The post-war 1950s–70s residential with some 1980s–90s infill; Sovereign Harbour development adjacent in Langney 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 Langney 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 Langney 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.

Why GRP Is the Right Specification for Langney
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 Langney — 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 Langney Properties
Falls of 1:80 minimum are required across any flat roof surface. In practice we target 1:60 on new installations in Langney to account for settlement. Outlets must be sized for the catchment area — undersized outlets are the most common cause of ponding on existing Langney flat roofs. We assess drainage as part of every survey and specify correctly from the start.
Deck Inspection Before Your Langney Flat Roof
Before laying any new flat roof covering in Langney, we expose and inspect the deck. Soft spots, delaminated plywood and degraded timber all need addressing before the membrane goes down. On most Langney 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.
