When does a garage roof in East Grinstead need replacing?
If your garage in East Grinstead has an old cement sheet roof, it will eventually crack and let in water. Any suspected asbestos is tested and removed by a licensed specialist first, then the garage can be given new timbers, a deck and a modern membrane that should last for decades with sensible maintenance.
Around East Grinstead, flat roofs are common on low-rise post-war blocks of flats and on bungalows with flat-roofed side extensions and dormers. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a new garage roof cost in East Grinstead?

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?
- New membrane dressed into fresh edge and drip trims
- Replacement of soft or swollen deck boards
- Strip-out of old felt, chippings and waste
- 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.

Can a garage roof be replaced in one day?
A small single garage with a sound deck can often be stripped and re-covered in a day. Deck repairs, a double garage or poor weather can stretch it to two or three.
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.
