What flat roof work do we do in Cambridge?

Torch-on felt roofing

Where a flat roof in Cambridge already has a felt covering and the building owner wants like-for-like, torch-on is the natural replacement. The old roof is stripped, the deck checked and the new layers laid, often with warm-roof insulation added when the space below is heated.

Flat roof repairs

Buying or selling a property in Cambridge 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.

Flat roof surveys and leak tracing

Flat roofs in Cambridge hide their problems well. A covering can look fine while the insulation beneath it is wet or the deck is softening. A survey with moisture readings and core samples shows what's happening under the surface before it reaches the ceiling.

What flat roofs are typical in and around Cambridge?

In a large town like Cambridge 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. Local weather shapes the specification. 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 Cambridge?

Where approval is needed it goes to Cambridge 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.
