What flat roof work do we do in Horwich?
Flat roof replacement
A sensible moment to replace a flat roof in Horwich 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.
Flat roof repairs
Buying or selling a property in Horwich with a tired flat roof? A surveyor's report may flag damp, blistering or ponding. A targeted repair can deal with an isolated defect, and where the roof is near the end of its life we will explain that clearly so the cost can be planned.
Dormer roofs
A dormer roof that has been patched several times in Horwich 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.

What flat roofs are typical in and around Horwich?
In a town like Horwich flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and newer estates where the first extension roofs are now being replaced. Rain and wind decide how a flat roof is detailed. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Horwich?
Where approval is needed it goes to Bolton Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.
