What flat roof work do we do in Epsom?

Flats, HMOs and block roofs

Fire performance matters near boundaries and on occupied buildings in Epsom. We check the external fire classification of the whole roof build-up, not just the membrane, control or avoid hot works near escape routes and windows, and keep fire-stopping details intact where the roof crosses a separating wall.

Flat roof surveys and leak tracing

Buyers in Epsom sometimes find a general survey flags a flat roof as a concern without saying much more. A specific flat roof survey fills that gap, describing the condition and likely cost of any work so it can be factored into the decision.

Garage roofs

A garage in Epsom that is becoming a workshop, gym or home office is a good reason to replace its roof. That is the moment to think about insulation and a warm-roof build-up, so the roof does not have to be stripped again when the space is heated.

What flat roofs are typical in and around Epsom?

In a town like Epsom flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and 1930s semis with flat-roofed garages and kitchen extensions. 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.
