What flat roof work do we do in Llantwit Major?

GRP fibreglass roofing

Some Llantwit Major homeowners pick GRP for appearance alone. The topcoat comes in several colours, the trims are moulded to match, and the finished roof looks tidy from upstairs windows. With good laying conditions and a sound deck, a GRP roof typically lasts 20 years or more.

Flats, HMOs and block roofs

Fire performance matters near boundaries and on occupied buildings in Llantwit Major. We check the external fire classification of the whole roof build-up, not just the membrane, control or avoid hot works near escape routes and windows, and keep fire-stopping details intact where the roof crosses a separating wall.

Liquid-applied roofing

If a flat roof in Llantwit Major is ageing but still dry, firmly bonded and on a sound deck, a reinforced liquid system can be applied over it. That avoids the cost and mess of a full strip-out, provided the moisture and adhesion checks at survey show the existing roof is fit to build on.
