Flat Roof Repair
Eastleigh
CMW Roofing & Renovations carries out flat roof repair and replacement across Eastleigh and the surrounding SO50 area. Eastleigh has a large amount of housing built in the 1960s through 1980s — many properties have garage and extension flat roofs that are now past the end of their felt lifespan. We replace them with GRP fibreglass systems that are seamless, durable and guaranteed for 20 years.
GRP Flat Roofing in Eastleigh
A large portion of Eastleigh's housing stock was built between the 1960s and 1980s. Many of these properties have garages and rear extensions with flat roofs laid in traditional felt — a system that lasts around 10–15 years before it starts leaking at the lap joints.
A like-for-like felt replacement simply restarts the same clock. We replace aging felt in Eastleigh with GRP fibreglass instead — a seamless, jointless system that carries a 20-year manufacturer guarantee.
Repair or replace, we'll always tell you honestly which your roof actually needs.
How we install your GRP flat roof
- Strip and inspectThe existing felt is removed and the deck checked over — any soft or rotten boards are replaced so the new roof has a sound base.
- GRP trims and universal primerGRP edge trims are fixed around every perimeter and upstand, then a universal primer is applied across the full deck to seal it ready for the laminate.
- Matting and resin laminateFibreglass matting is laid into catalysed resin and rolled out to remove any air, bonding into one seamless, jointless layer across the whole roof.
- Sand, dust off and topcoatOnce the resin has cured we sand it back, dust it off and roll on the topcoat (matched to the system) for a hard-wearing, UV-stable, colour-fast finish.
Where the deck is sound and the damage is localised, we can carry out targeted GRP repairs rather than a full replacement. Every installation across the SO50 area includes a written workmanship guarantee alongside the manufacturer's 20-year product guarantee.
