What flat roof work do we do in Letchworth Garden City?
Dormer roofs
A dormer roof that has been patched several times in Letchworth Garden City often has layers of old repairs that hide the real fault. Stripping back to the deck shows what has been going on, and lets the team rebuild the back-edge abutment properly rather than sealing over it again.
Flat roof replacement
A sensible moment to replace a flat roof in Letchworth Garden City 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.
Liquid-applied roofing
Choose liquid roofing in Letchworth Garden City when the shape of the roof makes sheet materials awkward: curved edges, small dormers with many corners, or a mix of levels joined by short upstands. Each detail is reinforced in the same material as the main area, so the whole roof is continuous.
