When does a garage roof in Chichester need replacing?
Water from a failing garage roof in Chichester 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 Chichester, flat roofs are common on terraced streets with flat-roofed rear kitchens and bathrooms and on lock-up garage blocks on estates. 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 Chichester?
Guide price in Chichester: £1,750–£3,100 for a typical 18 m² garage roof in EPDM, including VAT at South East rates. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Single garage (18 m²), EPDM rubber | £1,750–£3,100 |
| Single garage (18 m²), torch-on felt | £1,650–£2,900 |
| Single garage (18 m²), GRP fibreglass | £1,950–£3,600 |
| Extension (20 m²), GRP, new deck + insulation | £3,300–£5,900 |
Which roofing system is best for a garage?
For most single garages, EPDM rubber is a strong choice, because a simple rectangle can usually be covered in one sheet with no joins in the field of the roof. It is light, flexible and quick to lay.
GRP fibreglass suits garages with integral box gutters, several corners or a roof that is walked on to reach windows or clean gutters. Torch-on felt remains a cost-effective, durable option, particularly on larger lock-up runs where budget matters. Where a garage adjoins timber or other combustible material, we also consider whether a torch-free system is the safer method, such as EPDM, GRP or a liquid-applied coating.
If you plan to convert the garage later, say so at survey. A roof built as a warm roof now saves stripping it again when the room is heated.
What's included?

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 Chichester?
£1,750–£3,100 for a typical 18 m² garage roof in EPDM, at South East guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.
How long does a garage roof last?
It depends on the system. As indicative figures, EPDM lasts 25–50 years, GRP 20–40 and modern torch-on felt 15–25, with good specification and maintenance.
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.
