What flat roof work do we do in Maidenhead?
Emergency leak repairs
Leaves and debris build up in outlets and gutters on flat roofs around Maidenhead, especially under trees. A blocked outlet can turn a normal rainstorm into a flood over the upstands. Clearing it is often part of the emergency visit, and the permanent fix looks at why it blocked.
Flat roof repairs
Landlords and managing agents in Maidenhead need a repair done properly once, rather than a quick fix that brings tenants back on the phone a month later. We trace the leak to its source and confirm the price in writing, so the repair can be approved and booked without guesswork.
Extension and kitchen roofs
Extension roofs in Maidenhead 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.

What flat roofs are typical in and around Maidenhead?
In a large town like Maidenhead flat roofs are mostly on newer estates where the first extension roofs are now being replaced 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.
Who approves flat roof work in Maidenhead?
Where approval is needed it goes to Royal Borough of Windsor and Maidenhead 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.
