What flat roof work do we do in Allerton?

EPDM rubber roofing

Choose EPDM in Allerton if you want a long service life without paying for a hard, walkable finish you do not need. With good detailing it typically lasts 25 years or more, and manufacturer material guarantees are available on many EPDM systems, registered for you where the system allows.

Emergency leak repairs

Older felt roofs in Allerton 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.

Commercial flat roofing

Businesses in Allerton need a roofing contractor who arrives with a plan, not just a price. We put the system, build-up, phasing, access and payment terms in a fixed written quote, and keep each section of the roof watertight before the team leaves site, so trading is not put at risk.

What flat roofs are typical in and around Allerton?

In a town like Allerton flat roofs are mostly on 1930s semis with flat-roofed garages and kitchen extensions and low-rise post-war blocks of flats. Rain and wind decide how a flat roof is detailed. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour. Approximate 1991–2020 regional averages based on Met Office data.

Where approval is needed it goes to Liverpool City Council building control, or a registered building control approver.
