How We Do Flat Roofs

We build flat roofs in single-ply and EPDM rubber, as warm or cold roofs, for extensions, garages, porches, dormers and outbuildings.

Warm or Cold?

In a warm flat roof the insulation sits above the deck, under the waterproof layer, so the timbers stay at room temperature. In a cold roof the insulation sits between the joists, with a ventilated gap above it to let moisture out. Which one suits depends on the roof you've got, and we'll say which we'd use when we quote.

EPDM, Felt, Liquid and GRP

We fit four flat roof systems. EPDM is a synthetic rubber sheet laid over the deck as a single-ply membrane. Felt is built up in layers bonded to the deck. A liquid system is brushed or rolled on and cures into one seamless waterproof coat, which suits roofs with a lot of upstands and awkward corners. GRP is glass reinforced plastic, a fibreglass mat set in resin that cures hard. We fit them on homes and on commercial buildings, and Lee holds a Level 2 qualification in single ply membrane flat roofing.

For Landlords

On one rental property we replaced the flat roof in less than two days, dealing directly with the rental management team, with very little impact on the tenants.
