What flat roof work do we do in Portslade?

Flats, HMOs and block roofs

When a roof over heated flats in Portslade is replaced, insulation rules usually apply. We design the warm-roof build-up towards the required standard where that is feasible and handle building control where it is needed, so the work is signed off properly and the top-floor flats are better insulated.

Commercial flat roofing

We are flat roof specialists, so a commercial roof in Portslade gets a system chosen for the job: single-ply for large, simple areas, built-up felt where there is foot traffic and plant, or a liquid overlay where the existing roof is sound. The survey explains the trade-offs in plain terms.

Dormer roofs

If your dormer in Portslade 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.

What flat roofs are typical in and around Portslade?

In a town like Portslade flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms and bungalows with flat-roofed side extensions and dormers. Local weather shapes the specification. 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.
