What flat roof work do we do in Banstead?
Emergency leak repairs
Flat roofs in Banstead, 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.
EPDM rubber roofing
EPDM makes sense for a property in Banstead when the roof is a straightforward shape, such as a garage or rear extension, and nobody needs to walk on it. A single sheet leaves few joins to fail, and because it is cold-applied there is no naked flame near timber fascias or a lived-in home.
Flat roof repairs
Small businesses in Banstead with a flat-roofed shop, office or unit can't leave a leak running over stock or equipment. A repair stops the water at its entry point, and our inspection tells you whether the rest of the roof needs attention soon or can safely be left for now.

What flat roofs are typical in and around Banstead?
In a town like Banstead flat roofs are mostly on shops with flat-roofed rear stores below flats 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.
Who approves flat roof work in Banstead?
Where approval is needed it goes to Reigate and Banstead Borough Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.
