What flat roof work do we do in Amersham?

Extension and kitchen roofs

If you're fitting a new kitchen under an extension in Amersham, that's a good time to replace the roof. It makes sense to rebuild the roof before fitting new units, ceilings and lighting below, and the insulation upgrade makes the room more comfortable all year.

Green and sedum roofs

If you're replacing an old flat roof in Amersham, it's worth deciding whether to add sedum at the same time. If the structure can take it, that is the ideal moment, because the waterproofing is new and the green layers won't need lifting for a long time.

Warm roof insulation upgrades

Kitchen extensions in Amersham, as elsewhere, produce a lot of moisture from cooking. Under a cold flat roof, that moisture can condense on the deck. A warm roof keeps the deck warm and puts a vapour control layer in the way, which lowers the risk considerably.

What flat roofs are typical in and around Amersham?

In a town like Amersham flat roofs are mostly on newer estates where the first extension roofs are now being replaced and shops with flat-roofed rear stores below 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.

Where approval is needed it goes to Buckinghamshire Council building control, or a registered building control approver.
