What flat roof work do we do in Dinas Powys?
Garage roofs
If your garage in Dinas Powys has an old cement sheet roof, it will eventually crack and let in water. Any suspected asbestos is tested and removed by a licensed specialist first, then the garage can be given new timbers, a deck and a modern membrane that should last for decades with sensible maintenance.
Warm roof insulation upgrades
Small commercial buildings in Dinas 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.
Single-ply membrane roofing
For a commercial roof in Dinas Powys with rooflights, plant and outlets, single-ply's welded details give a consistent finish. Pre-formed corners, membrane-coated trims and welded kerbs are all made in the same material as the main roof, which keeps the roof consistent and simplifies any future repairs.

What flat roofs are typical in and around Dinas Powys?
In a town like Dinas Powys flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and shops with flat-roofed rear stores below flats. 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. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Dinas Powys?
Where approval is needed it goes to Vale of Glamorgan Council building control, or a registered building control approver. Welsh guidance is that most re-roofing needs building control approval, so it's worth checking whenever more than a quarter of a roof is replaced or repaired. How the rules work.
