Which flat roofs are common in Vale of Glamorgan?
The climate is part of the brief. 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 Vale of Glamorgan, flat roofs are typically found on low-rise post-war blocks of flats, shops with flat-roofed rear stores below flats and lock-up garage blocks on estates. Approximate 1991–2020 regional averages based on Met Office data.
Which flat roof jobs do we take on in Vale of Glamorgan?
Garage roofs
Water from a failing garage roof in Vale of Glamorgan does not always stay in the garage. On an attached garage it can run down the house wall or track under the flashing, and a blocked or broken gutter can spill onto the drive or a neighbour's property. Replacing the roof deals with the source.
Balconies and roof terraces
A roof terrace in Vale of Glamorgan may be re-waterproofed when the owners want to change the finish, swapping old tiles for decking or porcelain on pedestals. Lifting the surface exposes the membrane, and replacing it then avoids having to lift the new finish again later.
EPDM rubber roofing
Rubber is a sensible pick in Vale of Glamorgan 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.
