What flat roof work do we do in East Grinstead?

Flat roof repairs

Buying or selling a property in East Grinstead 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.

Emergency leak repairs

Older felt roofs in East Grinstead that have lost their chippings dry out and crack, and a cold snap can open those cracks enough to let water through. A temporary repair stops the immediate leak, but a roof like that often needs a frank conversation about replacement.

Garage roofs

Water from a failing garage roof in East Grinstead does not always stay in the garage. On an attached garage it can run down the house wall or track under the flashing, and a blocked or broken gutter can spill onto the drive or a neighbour's property. Replacing the roof deals with the source.

What flat roofs are typical in and around East Grinstead?

In a town like East Grinstead flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and lock-up garage blocks on estates. Local weather shapes the specification. 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 East Grinstead?

Where approval is needed it goes to Mid Sussex District 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.
