Which flat roofs are common in Pembrokeshire?

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 Pembrokeshire, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, 1930s semis with flat-roofed garages and kitchen extensions and low-rise post-war blocks of flats. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in Pembrokeshire?

Extension and kitchen roofs

Ponding against the house wall is a common reason for replacing an extension roof in Pembrokeshire. When the deck dips near the wall or the fall runs the wrong way, water sits against the abutment and eventually gets in. A new roof with corrected falls moves the water to the gutter.

Garage roofs

A garage in Pembrokeshire that is becoming a workshop, gym or home office is a good reason to replace its roof. That is the moment to think about insulation and a warm-roof build-up, so the roof does not have to be stripped again when the space is heated.

EPDM rubber roofing

Choose EPDM in Pembrokeshire if you want a long service life without paying for a hard, walkable finish you do not need. With good detailing it typically lasts 25 years or more, and manufacturer material guarantees are available on many EPDM systems, registered for you where the system allows.

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.
