What flat roof work do we do in High Wycombe?

Single-ply membrane roofing

Single-ply also works on an extension or garage in High Wycombe if you want a light, clean finish in a pale colour. On small roofs it is usually adhered, and while it can cost more than EPDM, it gives the same welded seams and details found on commercial roofs.

Emergency leak repairs

Flat roofs in High Wycombe, as elsewhere, often fail during the first heavy storm of autumn or after a hard frost, when an old seam finally opens. That is often when people find water running down a wall or through a light fitting, and a temporary repair is needed quickly.

Commercial flat roofing

When a roof over heated space in High Wycombe 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 building is better insulated afterwards.

What flat roofs are typical in and around High Wycombe?

In a large town like High Wycombe flat roofs are mostly on lock-up garage blocks on estates and terraced streets with flat-roofed rear kitchens and bathrooms. The climate is part of the brief. 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.
