What flat roof work do we do in Chesham?
Flat roof replacement
A sensible moment to replace a flat roof in Chesham is when other work is planned on the house, such as a kitchen refit below, new windows or a loft conversion. Doing the roof first protects the new work, and it is the natural time to upgrade insulation to the level the regulations expect for a renovated roof.
Emergency leak repairs

EPDM rubber roofing
For landlords with property in Chesham, 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.

What flat roofs are typical in and around Chesham?
In a town like Chesham flat roofs are mostly on lock-up garage blocks on estates and low-rise post-war blocks of flats. Weather matters on a flat roof. 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 Chesham?
Where approval is needed it goes to Buckinghamshire 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.
