Which flat roofs are common in Blaenau Gwent?

Weather matters on a flat roof. 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 Blaenau Gwent, flat roofs are typically found on low-rise post-war blocks of flats, 1930s semis with flat-roofed garages and kitchen extensions and terraced streets with flat-roofed rear kitchens and bathrooms. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in Blaenau Gwent?

Liquid-applied roofing

Liquid systems suit balconies and walkways in Blaenau Gwent because they form neatly at door thresholds, railings and drains, and some products are designed to take foot traffic. Converting a roof into a new terrace is a different matter, and usually needs planning permission first.

EPDM rubber roofing

Rubber is a sensible pick in Blaenau Gwent where a roof sits close to bedrooms or a kitchen and you would rather avoid hot works. It suits porches, bays and dormers too, where the small area means a single sheet can cover the whole roof with no joins at all.

Single-ply membrane roofing

Single-ply often suits blocks and mixed-use buildings in Blaenau Gwent because no flame is used on the roof, which can make work around residents and businesses easier to plan. Hot-air welding still needs care, but the fire risk is lower than with torch-on.

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.
