What flat roof work do we do in Guildford?
Extension and kitchen roofs
Ponding against the house wall is a common reason for replacing an extension roof in Guildford. When the deck dips near the wall or the fall runs the wrong way, water sits against the abutment and eventually gets in. A new roof with corrected falls moves the water to the gutter.
Dormer roofs
If your dormer in Guildford was added years ago with a basic felt roof and little insulation, it will tend to fail at the edges first, and they leave the loft room cold in winter and hot in summer. A warm-roof replacement deals with both problems at once.
Single-ply membrane roofing
Single-ply is a common choice for medium and large flat roofs in Guildford because it covers big areas quickly, is light on the structure and has a long typical life. Wide rolls mean fewer seams, and those seams are welded and probed rather than glued.

What flat roofs are typical in and around Guildford?
In a large town like Guildford flat roofs are mostly on newer estates where the first extension roofs are now being replaced and low-rise post-war blocks of flats. 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.
Who approves flat roof work in Guildford?
Where approval is needed it goes to Guildford 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.
