When does a garage roof in Gloucester need replacing?
Garage roofs in Gloucester take the weather head-on, often with no shelter from surrounding buildings. Wind lifts loose edge trims, frost works at cracked felt, and leaves block small gutters. When several of these faults appear together, a new roof with fresh edges is usually better value than chasing each one.
In and around Gloucester, flat roofs are typically found on shops with flat-roofed rear stores below flats, and on lock-up garage blocks on estates. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage.
How much does a new garage roof cost in Gloucester?
At South West guide rates, a typical 18 m² garage roof in EPDM comes to £1,650–£2,900 including VAT. The fixed price comes after a free survey for new and replacement roofs.

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.

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 Gloucester?
£1,650–£2,900 for a typical 18 m² garage roof in EPDM, at South West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
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.
