Compact estate bounded by a339 and railway, sheltered position retains moisture. The 1960s–70s terraces, semis and low-rise flats along Essex Road, Norfolk Road, Suffolk Road present specific flat roofing challenges: heavy moss growth from enclosed humid microclimate. Our approach is tailored to these exact conditions — not a generic specification applied to every Basingstoke property regardless of its neighbourhood.
Step one: strip the existing covering completely. We never overlay new material on old — it hides deck problems, adds weight, and voids manufacturer guarantees. Step two: inspect the timber deck for rot, delamination and adequate structural support. Any compromised sections are replaced with marine-grade plywood. Step three: create correct drainage falls using tapered insulation or firring strips — minimum 1:40 gradient so water reaches the outlet rather than ponding.
For GRP, we apply resin and glass fibre matting in controlled conditions, building a seamless shell bonded to every surface including upstands, edge trims and pipe penetrations. For EPDM, the rubber membrane is fully bonded to the prepared deck with all edges and terminations mechanically secured and sealed.
Correct drainage separates a flat roof that lasts 25 years from one that fails in five. We calculate required falls from the roof area and outlet position, then build the gradient into the deck rather than relying on the membrane to shed water across a level surface. On Black Dam properties this matters because the enclosed humid microclimate accelerates every moisture-related failure mode compared to open estates.
GRP installations carry a 25-year manufacturer guarantee plus our 10-year workmanship guarantee. EPDM carries 20–25 years depending on the membrane specified. Both need minimal maintenance — clear the outlets twice a year and check the edges annually. We provide written aftercare guidance specific to your roof's design and your property's exposure to trees and debris.

Call 0125 624 2410For a simple rectangular garage roof with no upstands or complex details, EPDM is the sensible choice — quicker to install, less expensive, and entirely adequate for the job. For an extension roof with wall abutments, pipe penetrations, roof lights or anything you might walk on, GRP earns its premium through the seamless rigid finish and superior detail work.
Temperature also matters. GRP resin cures chemically and needs above 5°C with dry conditions, which limits winter installation. EPDM tolerates cooler conditions. If your flat roof fails in December, EPDM may be the practical option regardless of which you would prefer.
