Removing an asbestos garage roof from a single garage typically costs £400 to £800 for the strip-out alone, or £500 to £1,000 including licensed disposal. Most homeowners replace the roof in the same visit, which takes the full removal and replacement package to £1,500 to £3,000 in 2026.
A double garage usually adds 60 to 80 per cent to those figures. Size, access and region all move the price, and London jobs tend to sit at the top of each range.
This guide covers typical 2026 prices, what a proper quote must include, and the two mistakes that cost homeowners most: paying a licensed premium they do not need, and accepting a cheap quote with no disposal paperwork.
Asbestos Garage Roof Removal Prices in 2026
These are typical UK ranges for bonded asbestos cement garage roofs. Treat them as a sanity check for your quotes rather than a fixed menu.
| Job | Typical price | Notes |
|---|---|---|
| Roof removal only (single garage) | £400 to £800 | Strip and double-wrap the sheets; disposal priced separately |
| Removal including licensed disposal | £500 to £1,000 | Registered waste carrier plus consignment note |
| New steel box-profile roof, supply and fit | £950 to £1,800 | Single garage; sheets warrantied for up to 30 years |
| Full removal and replacement package | £1,500 to £3,000 | The most popular choice; usually finished in one day |
| Double garage (any option above) | Add 60 to 80 per cent | Garage blocks priced by roof area |
| Garage demolition including asbestos roof | £1,200 to £2,500 | Roof stripped and consigned first, then the structure taken down |
| Laboratory test of a sample | £40 to £120 | Confirms whether the roof contains asbestos |
Asbestos was banned in the UK in November 1999, so any garage roof fitted before 2000 falls inside the risk window. If you are not certain what your roof is made of, a laboratory test settles it for £40 to £120.
What a Proper Quote Should Include
A genuine asbestos removal quote covers four things in writing: the strip, the wrapping, the disposal and the paperwork.
The sheets should be removed whole with hand tools, damped down and never broken up, because the dust carries the risk. They are then double-wrapped in heavy-gauge polythene and taken to a licensed facility as hazardous waste, a process explained on our asbestos disposal page.
The paperwork matters just as much. The contractor must be a registered waste carrier, and you should receive a Hazardous Waste Consignment Note or disposal certificate proving where the sheets ended up. Keep it with your house documents, as buyers’ solicitors often ask for it when you sell.
What Affects the Price
Two similar-looking garages can come in hundreds of pounds apart. These are the factors that move the number:
- Roof size: single, double or a whole garage block
- Access: a garage on a driveway is far quicker than one in a terraced rear garden reached through a narrow alley
- Condition: broken or brittle sheets need slower, more careful handling and extra wrapping
- Disposal distance: the further the licensed facility, the higher the transport cost
- Timbers: rotten purlins or wall plates add materials and labour before a new roof goes on
- Region: London carries a premium over the wider South East

Removal Only or Removal and Replacement?
Removal on its own leaves you with an open garage, so it only makes sense if the building is coming down or you are re-roofing separately. If the garage is staying, replacing the roof in the same visit is almost always the better buy.
Much of the cost of any visit is labour, access and the disposal run, and those are paid once whether or not new sheets go on. A combined garage roof replacement at £1,500 to £3,000 works out cheaper than removal and a re-roof booked separately, and it is normally finished in a single day.
Our garage roof replacement cost guide breaks down the re-roofing side in detail. If the structure is past saving, garage demolition including the asbestos roof typically runs £1,200 to £2,500.
The Licensed Premium and Other Ways to Overpay
Here is the fact that saves homeowners the most money. Removing whole bonded asbestos cement sheets is normally non-licensed work under the Control of Asbestos Regulations 2012, so no HSE licence is needed for a standard cement garage roof.
Licensed contractors are set up for high-risk materials such as sprayed coatings and pipe insulation, with enclosures and air monitoring priced in. Ask one to quote a garage roof and the figure can be double the going rate for precautions the job does not require. Never pay a licensed removal premium for a bonded cement roof.
What you should insist on is competence: trained operatives following HSE guidance and proper asbestos roof removal method, with sheets kept whole and damped down. That is the standard the regulations actually require.
At the other end of the market sits the cash-in-hand job at a price that looks too good to be true. The saving is usually made on disposal, and that means fly-tipping.
This is not just the contractor’s problem. Householders have a duty of care for their own waste, fly-tipping carries unlimited fines, and dumped sheets can be traced back to your address.
Before accepting any quote, ask for the waste carrier registration number and check it on the Environment Agency’s public register, ask where the sheets will be tipped, and confirm in writing that a consignment note is included. A legitimate contractor answers all three without hesitation.
Is It Worth Removing the Roof at All?
An asbestos cement roof in good condition is low risk while the sheets stay intact and undisturbed, so removal is not always urgent. The catch is that every pre-2000 roof is now decades old, and cement sheets grow brittle, crack under moss and frost, and start to leak.
Once sheets are breaking up, the roof is failing as a roof and the damaged material is slower and costlier to handle safely. Waiting rarely makes removal cheaper.
Whatever you decide, do not attempt the job yourself with a crowbar and a skip. Breaking sheets releases the fibres that safe removal is designed to avoid, and most household tips will not accept asbestos. Our guide on removing an asbestos garage roof yourself covers the rules in full.
