What flat roof work do we do in Brent?

GRP fibreglass roofing

If a flat roof in Brent has already been patched with fibreglass that keeps cracking, a full GRP replacement on a new, properly fixed deck often solves the problem. Cracks usually come from movement in the boards beneath, so renewing the deck and reinforcing the joints deals with the cause.

Single-ply membrane roofing

If a flat roof in Brent has poor falls and ponding, a single-ply re-roof with tapered insulation can correct both problems at once. The tapered boards build the fall into the insulation, and the membrane is laid over the top, with outlets set at the new low points.

Flat roof replacement

A flat roof in Brent is often worth replacing because it is the weak point of the building: heat escapes through an uninsulated deck, rooms below are cold in winter and hot in summer, and condensation marks the ceiling. A warm-roof replacement deals with comfort as well as leaks, so it is worth considering before the roof fails outright.

Who approves flat roof work in Brent?
