Garage roofs in Prestwich

Is your garage roof in Prestwich letting in water, sagging in the middle or shedding chippings? A new roof is usually a one or two day job. Our vetted teams, working under S&K, take the old covering off, put the deck right and finish with a membrane chosen for that garage.

When does a garage roof in Prestwich need replacing?

Garage roofs in Prestwich 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 and around Prestwich, flat roofs are typically found on 1960s and 1970s link-detached houses with flat-roofed garages and porches, and on lock-up garage blocks on estates. 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.

How much does a new garage roof cost in Prestwich?

For Prestwich we use North West rates: £1,500–£2,650 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.

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?

  • Free survey of the deck, fall and gutter line
  • 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 Prestwich?

£1,500–£2,650 for a typical 18 m² garage roof in EPDM, at North West guide rates including VAT. The fixed price comes after a free survey for new and replacement roofs.

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.
