Roof safety · how to identify it
Asbestos in your roof: what it looks like, and is it safe?
An asbestos “Super 6” fibro roof is a low-pitch, mouldy black-and-white cement-sheet roof with wide ~6-inch corrugations, and it looks nothing like the grey loose-fill insulation we pump in. Don’t cut, drill or disturb it; we can still insulate safely underneath it.

“The fact that I can't even tell it's 6 degrees outside when I wake up in the morning speaks for itself. Have wasted so much money attempting to heat and cool an uninsulated home. Worth every $.”

How to identify it
What an asbestos roof looks like.
The common asbestos roof is the “Super 6” profile, a hard cement sheet with wide corrugations about 6 inches (150mm) across. There’s a less common “Mini-orb” profile with corrugations about 3 inches across.
- Almost never painted from new, so it weathers to a distinctive mouldy black-and-white finish.
- Usually low-pitch, on smaller roofs up to about 120m², often with gable ends.
- The sheets are brittle and heavy, so they can't be walked on or replaced like a tile.
- It's a hard cement sheet, not a soft material, nothing like the grey cellulose we pump in.
The low pitch and that black mould make these roofs extremely hot in summer, which is exactly why insulating under them is worth doing.

The common worry, answered
Our cellulose insulation contains no asbestos.
People sometimes hear “fibre” and worry. Let me be clear: our cellulose is insulation made from upcycled plant fibre, with a natural mineral treatment against fire, mould, insects and rodents, made in our own Queensland factory and manufactured to the Australian Standard (AS/NZS 4859.1). There’s no asbestos and no formaldehyde in it. Asbestos was a hard, banned cement-sheet product; our insulation is a soft recycled-paper blanket. They have nothing in common. Here’s exactly what’s in our cellulose.
Some older homes also have loose-fill asbestos insulation sitting in the ceiling instead of sheeting, and it can look similar to our loose-fill cellulose at a glance. See how to tell loose-fill asbestos from cellulose.
Important: your safety
What you must never do to an asbestos roof.
Asbestos is banned in Australia because the fibres get into your lungs and cause cancer. A sound asbestos roof that’s keeping the water out is doing its job. The danger is disturbing it.
- Never sand, grind, cut or drill it. That releases the fibres. (So no cutting holes for roof vents or skylights.)
- Don't collect drinking water off an asbestos roof.
- Don't walk on or try to move the sheets, as they're brittle and need two-person handling by people who know what they're doing.
- Removal or replacement is a job for a licensed asbestos removalist; in Queensland a licence is required to remove more than 10m² of non-friable asbestos.
Authoritative guidance: asbestossafety.gov.au (the national Asbestos and Silica Safety and Eradication Agency), WorkSafe Queensland, and Safe Work Australia.
How we work with it
How we insulate under an asbestos roof, without disturbing it.
Where there’s a manhole or another way into the roof space, we pump Cellulose Fibre Insulation in from inside as a seamless blanket and the sheets are never touched. We never cut, drill, break, sand or water-blast fibre-cement. On a low-pitched fibre-cement roof we may unscrew an intact ridge cap by hand, lift it to pump underneath, and screw it back down in the same holes. If a cap or sheet is cracked or crumbling, we don’t touch it: a licensed asbestos removalist creates the access first, and we quote the rest once it exists.

If your asbestos roof has a leak, it’s most often a cracked ridge cap or the screws starting to weep (the original tar on them dries and cracks over the years). Tar-backed aluminium foil tape is a good fix, better than silicone, which tends to peel off with the top layer of fibres. As always, no cutting or grinding.
