What flat roof work do we do in Alton?

Flats, HMOs and block roofs

Leaseholders in Alton want to see where their money goes. Our itemised quotes show each element of the job separately, including scaffold, insulation and provisional sums for hidden defects, which makes them easier to share and compare when the freeholder or agent is consulting on the work.

Emergency leak repairs

Older felt roofs in Alton that have lost their chippings dry out and crack, and a cold snap can open those cracks enough to let water through. A temporary repair stops the immediate leak, but a roof like that often needs a frank conversation about replacement.

Torch-on felt roofing

On larger roofs in Alton with poor falls, torch-on felt pairs well with tapered insulation, which builds the fall into the insulation boards. That deals with ponding properly while adding insulation, rather than patching the low spots and waiting for the next leak.

What flat roofs are typical in and around Alton?

In a town like Alton flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and low-rise post-war blocks of flats. Rain and wind decide how a flat roof is detailed. 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. Approximate 1991–2020 regional averages based on Met Office data.
