When does a garage roof in Golborne need replacing?

Garage roofs in Golborne 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.

Golborne's flat roofs are mostly on low-rise post-war blocks of flats, with plenty on 1930s semis with flat-roofed garages and kitchen extensions too. 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.

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?

  • Written workmanship guarantee, with material guarantees registered where available
  • Gutter or outlet renewed where the old one has failed
  • Free survey of the deck, fall and gutter line
  • 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.

How much does a new garage roof cost in Golborne?

£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 replace a shared garage roof in a block?

Yes. We can quote for one garage in a row or the whole block, and we take care with the joins between bays so neighbouring roofs stay watertight.

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.
