When does a garage roof in Haringey need replacing?
A garage in Haringey that is becoming a workshop, gym or home office is a good reason to replace its roof. That is the moment to think about insulation and a warm-roof build-up, so the roof does not have to be stripped again when the space is heated.
In and around Haringey, flat roofs are typically found on Victorian and Edwardian terraces with flat-roofed back additions, and on kitchen extensions and roof terraces behind period houses. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature.
How much does a new garage roof cost in Haringey?
For Haringey we use London rates: £1,900–£3,350 is the guide for a typical 18 m² garage roof in EPDM, VAT included. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Single garage (18 m²), EPDM rubber | £1,900–£3,350 |
| Single garage (18 m²), torch-on felt | £1,800–£3,150 |
| Single garage (18 m²), GRP fibreglass | £2,150–£3,900 |
| Extension (20 m²), GRP, new deck + insulation | £3,600–£6,450 |
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.

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.

£1,900–£3,350 for a typical 18 m² garage roof in EPDM, at London 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.
Should I insulate my garage roof?
Only if the garage is heated or you plan to use it as a room. Insulating a cold, unheated garage roof can cause condensation unless it is designed carefully, so we advise case by case.
