When does a garage roof in Longsight need replacing?
Many garages in Longsight still carry their original mineral felt, which may have been patched several times. Once the chippings have washed off and the laps have split, water gets under the felt and into the deck, and patches stop holding. At that stage a full replacement is the practical fix.
Longsight's flat roofs are mostly on newer estates where the first extension roofs are now being replaced, with plenty on terraced streets with flat-roofed rear kitchens and bathrooms too. 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 Longsight?
For Longsight we use North West rates: £1,500–£2,650 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 | £1,500–£2,650 |
| Single garage (18 m²), torch-on felt | £1,450–£2,500 |
| Single garage (18 m²), GRP fibreglass | £1,700–£3,100 |
| Extension (20 m²), GRP, new deck + insulation | £2,850–£5,100 |
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
- New membrane dressed into fresh edge and drip trims
- Written workmanship guarantee, with material guarantees registered where available
- Gutter or outlet renewed where the old one has failed
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.

How much does a new garage roof cost in Longsight?
£1,500–£2,650 for a typical 18 m² garage roof in EPDM, at North West 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.
Should I insulate my garage roof?
Only if the garage is heated or you plan to use it as a room. Insulating a cold, unheated garage roof can cause condensation unless it is designed carefully, so we advise case by case.
