When does a garage roof in Nantwich need replacing?
Water from a failing garage roof in Nantwich 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 Nantwich, flat roofs are common on bungalows with flat-roofed side extensions and dormers 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.

What if my garage roof is asbestos cement or old felt?
If your garage has corrugated cement sheets, especially on a pre-2000 building, assume they could contain asbestos until a test says otherwise. We do not remove asbestos; any suspected material is tested and, if confirmed, removed by a licensed specialist before our work starts.
Once the old sheets have gone, the garage usually needs new timber joists or purlins and a deck before a membrane can go on. Old felt garages are more straightforward: the felt is stripped and the deck assessed in the usual way.
Lock-up blocks and rows of garages bring their own issues. A shared roof often has several owners, so we can quote per bay, or for the whole run where everyone agrees, which keeps the edges and joins between garages consistent. Attached garages need careful upstands and flashings where the roof meets the house wall, while detached ones are about edges, gutters and falls.
Not sure whether your roof needs replacing? Our guide to repair or replace sets out the signs.
What's included?
- Written workmanship guarantee, with material guarantees registered where available
- New membrane dressed into fresh edge and drip trims
- Replacement of soft or swollen deck boards
- 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 Nantwich?

Do I need to empty my garage before the roof is replaced?
It helps to clear valuable or delicate items, and to cover the rest with dust sheets. Debris can fall through gaps in an old deck during strip-out.
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.
