When does a garage roof in Bangor, Gwynedd need replacing?
A garage in Bangor, Gwynedd that is becoming a workshop, gym or home office is a good reason to replace its roof. That is the moment to think about insulation and a warm-roof build-up, so the roof does not have to be stripped again when the space is heated.
Around Bangor, Gwynedd, flat roofs are common on newer estates where the first extension roofs are now being replaced and on 1930s semis with flat-roofed garages and kitchen extensions. 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.
How much does a new garage roof cost in Bangor, Gwynedd?
For Bangor, Gwynedd we use Wales rates: £1,450–£2,600 is the guide for a typical 18 m² garage roof in EPDM, VAT included. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Single garage (18 m²), EPDM rubber | £1,450–£2,600 |
| Single garage (18 m²), torch-on felt | £1,400–£2,400 |
| Single garage (18 m²), GRP fibreglass | £1,650–£3,000 |
| Extension (20 m²), GRP, new deck + insulation | £2,750–£4,950 |
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's included?
- Strip-out of old felt, chippings and waste
- Written workmanship guarantee, with material guarantees registered where available
- New membrane dressed into fresh edge and drip trims
- Gutter or outlet renewed where the old one has failed
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.

How much does a new garage roof cost in Bangor, Gwynedd?
£1,450–£2,600 for a typical 18 m² garage roof in EPDM, at Wales guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
Can you put a new roof on a garage with a cement sheet roof?
Yes, once any suspected asbestos has been tested and removed by a licensed specialist. The garage then usually needs new timbers and a deck before the new membrane goes on.
Is it worth repairing a garage roof instead?
If the roof is generally sound and dry with one isolated defect, a repair is usually sensible. Widespread cracking, a soft deck or repeat leaks point to replacement.
