What flat roof work do we do in Canterbury?

EPDM rubber roofing

If your Canterbury roof has been patched more than once and the felt is cracking or blistering, a full replacement in EPDM can be better value than another repair. The rubber stays flexible through hot summers and freezing nights, and the replacement is the right point to bring the insulation up to standard.

Extension and kitchen roofs

If you're fitting a new kitchen under an extension in Canterbury, 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.

Torch-on felt roofing

Torch-on felt is widely specified for blocks of flats and HMOs, in Canterbury as elsewhere, because the system is well understood, widely repairable and governed by a British Standard code of practice. Three-layer builds with insulation are common on larger, multi-occupied roofs.

What flat roofs are typical in and around Canterbury?

In a large town like Canterbury flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and 1960s and 1970s link-detached houses with flat-roofed garages and porches. 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.

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