When does a garage roof in Cwmbran need replacing?
Garage roofs in Cwmbran are often replaced when the deck gives way. Chipboard decks swell and soften once they get wet, and you may see sagging between joists or feel the roof flex underfoot. Replacing the deck and covering together is usually more economical than repeated repairs.
In and around Cwmbran, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, and on terraced streets with flat-roofed rear kitchens and bathrooms. 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 Cwmbran?
For Cwmbran 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 |

How long does a garage roof replacement take?
A single garage roof is typically finished in one or two days, and a double garage in two or three, weather permitting. Deck repairs and new fascias add time.
Disruption is light. You will need to empty or cover anything stored in the garage, because dust and debris can fall through gaps in an old deck during the strip. The garage door may be out of use for part of the job, and the car is best parked elsewhere so a skip can sit on the drive. We keep the roof weathertight at the end of each day.
What's included?
- Strip-out of old felt, chippings and waste
- Gutter or outlet renewed where the old one has failed
- Free survey of the deck, fall and gutter line
- New membrane dressed into fresh edge and drip trims
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 Cwmbran?
£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.
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.
