When does a garage roof in Bognor Regis need replacing?
Garage roofs in Bognor Regis are often replaced when the deck gives way. Chipboard decks swell and soften once they get wet, and you may see sagging between joists or feel the roof flex underfoot. Replacing the deck and covering together is usually more economical than repeated repairs.
In a large town like Bognor Regis, flat roofs are commonly found on shops with flat-roofed rear stores below flats or terraced streets with flat-roofed rear kitchens and bathrooms. 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.

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?
- New membrane dressed into fresh edge and drip trims
- Gutter or outlet renewed where the old one has failed
- Replacement of soft or swollen deck boards
- Strip-out of old felt, chippings and waste
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 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.
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.
