What flat roof work do we do in Ely?

Dormer roofs

If your dormer in Ely 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.

Garage roofs

Many garages in Ely still carry their original mineral felt, which may have been patched several times. Once the chippings have washed off and the laps have split, water gets under the felt and into the deck, and patches stop holding. At that stage a full replacement is the practical fix.

GRP fibreglass roofing

If a flat roof in Ely has already been patched with fibreglass that keeps cracking, a full GRP replacement on a new, properly fixed deck often solves the problem. Cracks usually come from movement in the boards beneath, so renewing the deck and reinforcing the joints deals with the cause.

What flat roofs are typical in and around Ely?

In a town like Ely flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and 1930s semis with flat-roofed garages and kitchen extensions. Rain and wind decide how a flat roof is detailed. 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.

Where approval is needed it goes to East Cambridgeshire District Council building control, or a registered building control approver.
