Removing an asbestos garage roof in the UK typically costs between £400 and £1,000. A standard single garage with a corrugated cement roof sits near the lower end. The price climbs with the size of the roof, how difficult it is to reach, and whether you want a new roof fitted in its place. Most garage roofs are bonded asbestos cement, which is non-licensed work, so this is one of the more affordable asbestos jobs.
What drives the cost of an asbestos garage roof removal:
- Roof size and pitch (single, double, or longer outbuilding run)
- Access for a scaffold tower and for carrying sheets out whole
- Condition of the sheets (cracked or weathered sheets need extra care)
- Whether you want removal only, or removal plus a new roof
- Disposal, which on a quoted job is normally included
Figures are indicative UK averages; every roof is quoted individually after a quick look or a few photos.
Why are asbestos garage roofs so common?
Corrugated asbestos cement was the standard garage and outbuilding roofing material in Britain from the 1950s through to the 1980s. It was cheap, light, and fire resistant, so it ended up on hundreds of thousands of garages, sheds, and lean-tos. If your garage was built before the mid-1980s and has a grey, corrugated, slightly fibrous-looking roof, there is a good chance it is asbestos cement.
The good news is that bonded cement is lower risk than loose, friable asbestos, because the fibres are held inside the cement. It is safe while it is intact and left alone. The risk comes when sheets are cracked, drilled, cut, or smashed during a DIY removal, which releases fibres into the air. That is why removal is a controlled job rather than a weekend project.
How much does it cost to remove and replace an asbestos garage roof?
Removal and replacement are two separate jobs, and it helps to think of them that way when you read a quote.
The removal itself, for a typical single garage, usually lands around £400 to £700. Add a larger or double garage, a steep pitch, or awkward access, and it moves toward £1,000 or beyond.
The replacement roof is priced on top, and the figure depends entirely on the material you choose. The common options are galvanised steel box profile, a flat felt roof, torch-on felt, tiles to match the house, or fibre cement sheets. Each has a different cost and lifespan. Our asbestos roof removal and renewal page sets out the replacement choices in detail.
| Garage roof job | What it covers | Typical UK range |
|---|---|---|
| Removal only, single garage | Strip, bag, licensed disposal | £400 to £700 |
| Removal only, double or awkward access | As above, larger or harder reach | £700 to £1,000+ |
| Removal plus new roof | Removal then steel, felt or tiled roof | Quoted together, roof priced on the material |
Doing both at once is usually more efficient than removal now and a new roof later, because the access and labour overlap. If you only want the asbestos gone and will deal with the roof yourself, we can quote removal on its own.
Does the quote include disposal and paperwork?
Yes, and this is where cheap online prices can be misleading. Asbestos is hazardous waste. It has to be double-wrapped, carried by a licensed waste carrier, and taken to a facility that is licensed to accept asbestos, with a consignment note recording the transfer.
A Clearaway garage roof quote includes the safe removal, the protective equipment, transport by a licensed carrier, the disposal gate fee, and the consignment paperwork. A quote that looks unusually low is often one that leaves disposal off, which lands back on you afterwards. We explain the disposal rules in full on our safe asbestos waste disposal page.
Get a fixed price for your garage roof
Garage roofs are one of the jobs people most often fear will be expensive, and most often turn out to be more manageable than expected. Because the material is usually bonded cement and the access is from outside, a single garage roof is one of the more straightforward asbestos removals we do.
A Clearaway quote gives you a fixed figure covering safe removal, all protective equipment, transport by a licensed carrier, disposal at a licensed facility, and the consignment paperwork. If you want the roof replaced, we quote the new roof alongside it so you can see both numbers and decide. We cover garages and outbuildings across London, Surrey, Sussex and the South East, and you can see examples of completed jobs on our asbestos garage and shed removal page.
