Which flat roofs are common in Powys?

Rain and wind decide how a flat roof is detailed. 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 Powys, flat roofs are typically found on 1930s semis with flat-roofed garages and kitchen extensions, terraced streets with flat-roofed rear kitchens and bathrooms 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 Powys?

Warm roof insulation upgrades

Small commercial buildings in Powys with large flat roofs can lose a lot of heat through them. Where the roof is being replaced, upgrading the insulation at the same time is required in most cases and helps reduce running costs for the occupier.

GRP fibreglass roofing

For a garage or extension in Powys that doubles as a step-out space for window cleaning, GRP gives a firmer footing than a rubber membrane. With an anti-slip topcoat it handles light, occasional use, though a full terrace needs its own specification and, in many cases, planning permission.

Flat roof replacement

A sensible moment to replace a flat roof in Powys is when other work is planned on the house, such as a kitchen refit below, new windows or a loft conversion. Doing the roof first protects the new work, and it is the natural time to upgrade insulation to the level the regulations expect for a renovated roof.

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.
