Which flat roofs are common in Neath Port Talbot?
Flat roofs in Neath Port Talbot sit on terraced streets with flat-roofed rear kitchens and bathrooms, 1930s semis with flat-roofed garages and kitchen extensions and newer estates where the first extension roofs are now being replaced. 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.
Building regulations in Wales
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. Renovated roofs are upgraded to around 0.16 W/m²K where feasible, and new extension roofs are built to 0.13 W/m²K under the Welsh Approved Document L. In Neath Port Talbot the application goes to Neath Port Talbot County Borough Council. More on the rules.
Which roofing system is best for a garage?
For most single garages, EPDM rubber is a strong choice, because a simple rectangle can usually be covered in one sheet with no joins in the field of the roof. It is light, flexible and quick to lay.
GRP fibreglass suits garages with integral box gutters, several corners or a roof that is walked on to reach windows or clean gutters. Torch-on felt remains a cost-effective, durable option, particularly on larger lock-up runs where budget matters. Where a garage adjoins timber or other combustible material, we also consider whether a torch-free system is the safer method, such as EPDM, GRP or a liquid-applied coating.
If you plan to convert the garage later, say so at survey. A roof built as a warm roof now saves stripping it again when the room is heated.
What if my garage roof is asbestos cement or old felt?
If your garage has corrugated cement sheets, especially on a pre-2000 building, assume they could contain asbestos until a test says otherwise. We do not remove asbestos; any suspected material is tested and, if confirmed, removed by a licensed specialist before our work starts.
Once the old sheets have gone, the garage usually needs new timber joists or purlins and a deck before a membrane can go on. Old felt garages are more straightforward: the felt is stripped and the deck assessed in the usual way.
Lock-up blocks and rows of garages bring their own issues. A shared roof often has several owners, so we can quote per bay, or for the whole run where everyone agrees, which keeps the edges and joins between garages consistent. Attached garages need careful upstands and flashings where the roof meets the house wall, while detached ones are about edges, gutters and falls.

Can you replace a shared garage roof in a block?
Yes. We can quote for one garage in a row or the whole block, and we take care with the joins between bays so neighbouring roofs stay watertight.
Do I need to empty my garage before the roof is replaced?
It helps to clear valuable or delicate items, and to cover the rest with dust sheets. Debris can fall through gaps in an old deck during strip-out.
