What flat roof work do we do in Havant?

Green and sedum roofs

Small commercial buildings and blocks in Havant with a flat roof sometimes add an extensive green roof as part of a refurbishment. The structural check and safe access for maintenance matter even more on these larger roofs, which may need edge protection or fall-arrest points for each visit.

Extension and kitchen roofs

Extension roofs in Havant are often replaced because the original was built cheaply: thin chipboard decks, little or no insulation and felt turned up the wall without a proper flashing. Twenty or thirty years on, those weaknesses show up as leaks at the back wall and a cold, damp ceiling.

Emergency leak repairs

Businesses in Havant can't trade properly with water dripping onto the shop floor or into an office. An emergency visit makes the roof temporarily weathertight, and the inspection that follows tells you whether a repair will hold or the roof needs replacing.

What flat roofs are typical in and around Havant?

In a town like Havant flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions and 1960s and 1970s link-detached houses with flat-roofed garages and porches. The climate is part of the brief. 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.
