Which flat roofs are common in Caerphilly?

Local weather shapes the specification. Wales averages roughly 1,460 mm of rain a year, among the wettest in Britain, so we design for steady run-off: proper falls, clear outlets and upstands well above the finished roof. Across Caerphilly, flat roofs are typically found on lock-up garage blocks on estates, bungalows with flat-roofed side extensions and dormers and 1960s and 1970s link-detached houses with flat-roofed garages and porches. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in Caerphilly?

Dormer roofs

A dormer roof that has been patched several times in Caerphilly often has layers of old repairs that hide the real fault. Stripping back to the deck shows what has been going on, and lets the team rebuild the back-edge abutment properly rather than sealing over it again.

Emergency leak repairs

Leaves and debris build up in outlets and gutters on flat roofs around Caerphilly, especially under trees. A blocked outlet can turn a normal rainstorm into a flood over the upstands. Clearing it is often part of the emergency visit, and the permanent fix looks at why it blocked.

Commercial flat roofing

Owners and agents in Caerphilly can plan spending with a phased programme: urgent repairs now, then re-roofing section by section over one or more budget years. Each phase is priced separately in writing, and the survey and quote for replacement work are free, with no obligation to go ahead.

Building regulations in Wales

The Welsh Approved Document L applies. Renovating more than half of a roof over a heated room means upgrading it to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K. Welsh Government guidance is that most re-roofing needs building control approval, so check whenever more than a quarter of a roof is replaced or repaired. We deal with the application as part of the job. More on the rules.
