What flat roof work do we do in Chelmsford?

Extension and kitchen roofs

Extension roofs in Chelmsford 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.

EPDM rubber roofing

EPDM makes sense for a property in Chelmsford when the roof is a straightforward shape, such as a garage or rear extension, and nobody needs to walk on it. A single sheet leaves few joins to fail, and because it is cold-applied there is no naked flame near timber fascias or a lived-in home.

Flat roof surveys and leak tracing

In Chelmsford, as elsewhere, people often book a survey after a repair that didn't hold. When a leak returns, it usually means the first fix treated the symptom rather than the cause. Tracing the actual entry point saves paying for the same repair twice.

What flat roofs are typical in and around Chelmsford?

In a large town like Chelmsford flat roofs are mostly on newer estates where the first extension roofs are now being replaced and 1930s semis with flat-roofed garages and kitchen extensions. The climate is part of the brief. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof. Approximate 1991–2020 regional averages based on Met Office data.

Who approves flat roof work in Chelmsford?

Where approval is needed it goes to Chelmsford City 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.
