Which flat roofs are common in Newport?

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 Newport, flat roofs are typically found on shops with flat-roofed rear stores below flats, 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 Newport?

Balconies and roof terraces

Settled, rocking or cracked paving is a common reason to re-waterproof a terrace in Newport. Slabs bedded directly on the membrane can damage it over time. Relaying them on adjustable pedestals protects the waterproofing and gives a level surface that drains underneath.

Flat roof repairs

Buying or selling a property in Newport with a tired flat roof? A surveyor's report may flag damp, blistering or ponding. A targeted repair can deal with an isolated defect, and where the roof is near the end of its life we will explain that clearly so the cost can be planned.

EPDM rubber roofing

Rubber is a sensible pick in Newport 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.

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.
