What flat roof work do we do in Chertsey?

Flat roof replacement

Flat roofs in Chertsey get replaced for the same reasons as anywhere else: the covering has reached the end of its service life, leaks keep returning after repairs, or water ponds because the deck has sagged. Once the boards are soft or the insulation is wet, a full strip usually costs less than another round of patching.

Torch-on felt roofing

For a commercial roof in Chertsey, such as a shop, surgery or club, torch-on felt offers a hard-wearing mineral finish that takes occasional maintenance traffic. Phased work keeps part of the building weathertight while the rest is re-roofed, so the business can usually keep trading.

Commercial flat roofing

Businesses in Chertsey 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 Chertsey?

In a town like Chertsey flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and 1930s semis with flat-roofed garages and kitchen extensions. 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. Approximate 1991–2020 regional averages based on Met Office data.

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