- Paint, seal or replace?
Can you paint an asbestos roof?
Only if nobody cleans it first. That rules out most paint jobs.
The Asbestos Abatement Regulations, 2020 allow painting without surface preparation, and they ban cleaning or preparing asbestos cement outright. Here is what that means for painting, sealing, living under the roof, and when replacing it makes more sense.
Yes, but only in a way that needs no cleaning, scraping, sanding or pressure-washing first. Regulation 24(b) says no person may clean or prepare the surfaces of asbestos cement materials, so the prep step every paint job normally starts with is the step the law bans.
Painting also changes nothing about what the roof is. It is still asbestos cement: it still cannot carry solar panels, it still belongs on a workplace asbestos inventory, and it still has to come off under the same rules when it fails.

The regulations sort asbestos work into three types, and list a set of things nobody may do. This is how they apply to a roof.
| Job on the roof | Who may do it |
|---|---|
| Painting with no surface preparationType 1 asbestos work: must not release fibres | No registration needed |
| Removing less than 10 m²Type 1, and not repeated on the same site within six months | No registration needed |
| Repairing or encapsulating (sealing) the sheetsType 2 asbestos work, done without surface preparation | Type 2 registered contractor |
| Removing the roofType 2 asbestos work for asbestos cement | Type 2 registered contractor |
| Cleaning or preparing the surfaceScrubbing, wire-brushing, sanding, pressure-washing: regulation 24(b) | Nobody |
| Cutting, grinding or drilling with power toolsAngle grinders or any fast-moving equipment: regulation 24(f) | Nobody |
| Reusing or reinstalling old sheetsSelling, donating, reusing, recycling: regulation 24(a) | Nobody |

Paint, seal or replace?
Three options, and what each one actually changes.
Paint it
Allowed only without any prep, which is hard to do well on an old, dirty roof: paint makers want a clean, sound surface, and on asbestos cement the cleaning is the banned part. It changes the colour, not the material. Solar stays off the table.
Seal it
Encapsulation is type 2 work for a registered contractor. It can hold a sound roof together for longer, but the sheets are still asbestos, still have to be listed where the building is a workplace, and still have to come off under the full rules when they fail.
Replace it
The only option that ends the problem. Strip and dispose runs R150 to R250 per m² in Gauteng, and a new steel roof starts at R500 per m². After a replacement the roof can carry solar, and the roof stops being an asbestos question when you sell.
Can you live in a house with an asbestos roof?
Yes, while the roof is intact and left alone. The National Institute for Occupational Health puts it plainly: the significant health risk comes when asbestos-containing materials are disturbed in an uncontrolled way, the fibres get into the air and people breathe them in. The diseases linked to asbestos, asbestosis, mesothelioma and lung cancer, typically appear decades after exposure, which is why prevention matters more than reassurance.
What turns a low-risk roof into a real one:
- Damage. Cracked, broken or crumbling sheets, hail damage and badly weathered edges.
- Cleaning. Pressure-washing, scrubbing or wire-brushing, which the regulations ban for exactly this reason.
- Drilling and cutting. Fixing a satellite dish or a geyser bracket with a power drill is banned on asbestos cement.
- Walking on it. Asbestos-cement sheets are brittle: a foot through the roof is a fall and a fibre release at once.
If the roof shows any of those, have it looked at before it gets worse. Not sure it is asbestos? Start with the visual checks.

Questions people ask about painting and living under an asbestos roof
Can I pressure-wash my asbestos roof before painting it?
No. Regulation 24(b) of the Asbestos Abatement Regulations, 2020 says no person may clean or prepare the surfaces of asbestos cement materials, and the National Institute for Occupational Health warns against abrasive materials and high-pressure water on these roofs because they release fibres.
Do I need a registered contractor to paint an asbestos roof?
Not for plain painting that needs no surface preparation and releases no fibres, which the regulations class as type 1 asbestos work. Repairing or encapsulating asbestos cement is type 2 work and needs a type 2 registered asbestos contractor.
Can I put solar panels on an asbestos roof once it is painted?
No. Painting does not change what the sheets are made of, and the Department of Employment and Labour's instruction of 9 November 2022 bars installing panels on asbestos roofs. The roof has to be replaced first.
Is it safe to live in a house with an asbestos roof?
An intact, undisturbed asbestos-cement roof is a low risk. The National Institute for Occupational Health says the significant health risk comes when asbestos-containing materials are disturbed in an uncontrolled way and the fibres are breathed in. Cracked, crumbling or hail-damaged sheets should be assessed.
Can I drill into an asbestos roof to fix a leak or mount something?
Not with power tools. Regulation 24(f) bans using electrical power tools such as angle grinders, or any other fast-moving equipment, to cut, grind or drill asbestos-containing material.
Can I reuse old asbestos sheets on a carport or shed?
No. Regulation 24(a) bans selling, donating, reusing, reinstalling or recycling any asbestos or asbestos-containing material. Removed sheets go to a licensed landfill with a disposal certificate.
