When does a garage roof in Northwich need replacing?
Water from a failing garage roof in Northwich 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.
Around Northwich, flat roofs are common on lock-up garage blocks on estates and on terraced streets with flat-roofed rear kitchens and bathrooms. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour.
How much does a new garage roof cost in Northwich?
Guide price in Northwich: £1,500–£2,650 for a typical 18 m² garage roof in EPDM, including VAT at North West rates. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Single garage (18 m²), EPDM rubber | £1,500–£2,650 |
| Single garage (18 m²), torch-on felt | £1,450–£2,500 |

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?
- Written workmanship guarantee, with material guarantees registered where available
- Strip-out of old felt, chippings and waste
- Gutter or outlet renewed where the old one has failed
- New membrane dressed into fresh edge and drip trims
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.
