What flat roof work do we do in Bicester?

Single-ply membrane roofing

Single-ply is a common choice for medium and large flat roofs in Bicester 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.

EPDM rubber roofing

For landlords with property in Bicester, EPDM's low upkeep is the main draw: once the outlets are kept clear and the trims are checked once or twice a year, there is little else to do. It also goes down quickly on a small roof, which keeps disruption for tenants to a minimum.

Garage roofs

Many garages in Bicester still carry their original mineral felt, which may have been patched several times. Once the chippings have washed off and the laps have split, water gets under the felt and into the deck, and patches stop holding. At that stage a full replacement is the practical fix.

What flat roofs are typical in and around Bicester?

In a town like Bicester flat roofs are mostly on shops with flat-roofed rear stores below flats and 1960s and 1970s link-detached houses with flat-roofed garages and porches. 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 Bicester?

Where approval is needed it goes to Cherwell District 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.
