What flat roof work do we do in Penarth?

Dormer roofs

If your dormer in Penarth 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.

EPDM rubber roofing

For landlords with property in Penarth, EPDM's low upkeep is the main draw: once the outlets are kept clear and the trims are checked once or twice a year, there is little else to do. It also goes down quickly on a small roof, which keeps disruption for tenants to a minimum.

Flats, HMOs and block roofs

Fire performance matters near boundaries and on occupied buildings in Penarth. 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.
