What flat roof work do we do in Dover?

Garage roofs

Garage roofs in Dover take the weather head-on, often with no shelter from surrounding buildings. Wind lifts loose edge trims, frost works at cracked felt, and leaves block small gutters. When several of these faults appear together, a new roof with fresh edges is usually better value than chasing each one.

Extension and kitchen roofs

Extension roofs in Dover 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.

Liquid-applied roofing

Liquid systems suit balconies and walkways in Dover because they form neatly at door thresholds, railings and drains, and some products are designed to take foot traffic. Converting a roof into a new terrace is a different matter, and usually needs planning permission first.

What flat roofs are typical in and around Dover?

In a town like Dover 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 Dover?

Where approval is needed it goes to Dover 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.
