What flat roof work do we do in Didcot?

Liquid-applied roofing

Liquid roofing suits a roof in Didcot that is full of penetrations, such as soil pipes, vents, aerial brackets and rooflights, because the liquid flows around each one and cures into a single skin. There are no cut pieces or taped corners to work loose over time.

Flat roof replacement

A sensible moment to replace a flat roof in Didcot is when other work is planned on the house, such as a kitchen refit below, new windows or a loft conversion. Doing the roof first protects the new work, and it is the natural time to upgrade insulation to the level the regulations expect for a renovated roof.

Dormer roofs

Dormer roofs in Didcot are often replaced when the loft room below starts to show damp, particularly along the back wall or around the window head. By then the deck may be wet, so a full rebuild with new insulation is usually the better choice than patching from a ladder.
