What flat roof work do we do in Ewell?
Commercial flat roofing
When a roof over heated space in Ewell 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 building is better insulated afterwards.
Liquid-applied roofing
Liquid systems suit balconies and walkways in Ewell 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.
Dormer roofs
If your dormer in Ewell was added years ago with a basic felt roof and little insulation, it will tend to fail at the edges first, and they leave the loft room cold in winter and hot in summer. A warm-roof replacement deals with both problems at once.

What flat roofs are typical in and around Ewell?
In a town like Ewell flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms and newer estates where the first extension roofs are now being replaced. Rain and wind decide how a flat roof is detailed. 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 Ewell?
Where approval is needed it goes to Epsom and Ewell Borough 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.
