How much does asbestos garage roof removal and replacement cost?

Typical price ranges

For a single garage, removal and disposal of an asbestos cement roof commonly costs in the region of £600 to £1,000. For a double garage it is more often £1,000 to £1,600. Add a new steel roof and the single-garage total usually lands between £2,000 and £3,500, and between £3,400 and £4,800 for a double.

Surveys of local price comparison sites show wide spreads, because unlicensed removal of cement sheets is a smaller job than licensed removal of insulation or lagging. Do not take the cheapest number without checking what it includes.

What moves the price

Roof area is the main driver, followed by access. A garage in a narrow back lane in Gorton or Levenshulme, where a skip cannot sit outside, costs more to clear than a driveway garage in Sale. Scaffold, extra outbuildings, rotten timbers, new gutters and fascia all add to a quote.

The roof you choose matters too. Box profile steel is usually the economical pitched roof, EPDM rubber or GRP for flat roofs costs more, and anything insulated or coloured to order adds again.

What to check is included

A good quote lists scaffold or access equipment, removal and disposal, waste paperwork, repairs to timbers, the new roof covering, gutters and fascia, and clearing up. If a quote says only "asbestos roof removal" with no mention of waste paperwork, ask.

Ask whether VAT is included and whether a sample test is part of the price.

How to get a fair price

Send the same photos and the same description to more than one firm so the quotes can be compared like for like. A written quote after a proper look at the roof is better than a number over the phone, and it should say what happens if the timbers turn out to be worse than expected.
