Flat Roofing in Langney — GRP and EPDM
Flat roofs on Langney properties are predominantly felt systems from the 1970s to 1990s, most at or past end of service life. The correct replacement system for Eastbourne's coastal position is either GRP fibreglass (for areas under 50m² with stable substrates) or EPDM rubber (for larger areas or movement-prone substrates). Neither requires replacement within 25–50 years if correctly installed.
The most common reason flat roofs on Langney extensions fail prematurely is not the membrane system — it's inadequate drainage falls. Falls correction is included as standard in every flat roof replacement we carry out in Langney. We assess and correct falls before any new membrane goes down.
Deck Condition on Langney Properties
Before any flat roof replacement in Langney, we assess deck condition with a moisture meter and visual inspection. Waterlogged or failed OSB or plywood sheets are replaced before new membrane is applied. Deck assessment is at every survey; deck replacement is quoted transparently as a separate line item where required.
