What flat roof work do we do in Egham?

Single-ply membrane roofing

Single-ply also works on an extension or garage in Egham 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.

Commercial flat roofing

A commercial re-roof in Egham has to fit around customers, staff and deliveries. We agree working hours, skip positions and access routes before we start, keep fire exits clear throughout, and choose a flame-free system where your site does not allow hot works near stock or occupied rooms.

GRP fibreglass roofing

If a flat roof in Egham has already been patched with fibreglass that keeps cracking, a full GRP replacement on a new, properly fixed deck often solves the problem. Cracks usually come from movement in the boards beneath, so renewing the deck and reinforcing the joints deals with the cause.

What flat roofs are typical in and around Egham?

In a town like Egham flat roofs are mostly on shops with flat-roofed rear stores below flats 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. 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.
