What flat roof work do we do in Crawley?

Flat roof repairs

Buying or selling a property in Crawley 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.

Commercial flat roofing

Safety planning matters on commercial sites in Crawley. Every job is planned under CDM, with a method statement, edge protection and covers over rooflights and fragile areas. If asbestos is found, a licensed specialist surveys and removes it before our work starts, so nobody is put at risk.

Flats, HMOs and block roofs

When a roof over heated flats in Crawley is replaced, insulation rules usually apply. We design the warm-roof build-up towards the required standard where that is feasible and handle building control where it is needed, so the work is signed off properly and the top-floor flats are better insulated.

What flat roofs are typical in and around Crawley?

In a large town like Crawley flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions and lock-up garage blocks on estates. Weather matters on a flat roof. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain. Approximate 1991–2020 regional averages based on Met Office data.
