You’ve prised a cracked sheet off the back fence, or pulled up a floor tile ahead of new flooring, and now you’re standing there holding it, wondering if what you’re looking at is asbestos. Typing “what does asbestos look like” into your phone at that point is exactly the right instinct. The awkward truth is that in a lot of Geelong homes built between the 1940s and the late 1980s, the honest answer is that you often can’t tell just by looking, and the piece in your hand may already be more disturbed than it should be.
Some forms of asbestos are recognisable once you know what to look for: a jagged, brittle edge on old wall sheeting, a particular ridge pattern on a corrugated roof, a patterned floor tile from an era before vinyl went plain. Others give away nothing at all. A ceiling that looks exactly like ordinary plasterboard can be asbestos cement, and a fluffy grey coating sprayed over a beam decades ago can be some of the most dangerous material in the house.
What asbestos cement (fibro) looks like on walls, fences and eaves
Fibro is the local word for asbestos cement sheeting, and it’s the material you’ll meet most often outside a Geelong home. It’s a flat, rigid sheet, usually a handful of millimetres thick, sold under brand names including Hardiflex, Fibrolite, Fibrock, Fibrocene and Tasbestos. Most contain chrysotile (white) asbestos at around 15 percent of the sheet, though one manufacturer, CSR Fibrock, used crocidolite (blue) asbestos in some of its product instead.
The biggest visual clue is how it breaks. Undamaged fibro looks like any other flat cement sheet, grey or painted, sometimes rendered over so you can’t see the sheet at all. Where it’s cracked or been struck, the break is characteristically jagged, rather than the cleaner snap you’d get from modern fibre cement. Painted sheeting is the real trap, because paint can hide the asbestos completely and a freshly painted fence gives you no clue either way.
If your fence, garage wall or eaves lining went up before 1990, and especially before the mid-1980s, it’s safest to assume it’s fibro until a laboratory says otherwise. For brand-specific clues, see our guide on telling if your fibro is Hardiflex or Villaboard. Eaves are their own case, covered in a separate guide, because the soffit lining tends to go unnoticed until a renovation opens it up.
Take a 1960s fibro fence line along the back boundary in Norlane, cracked along three panels after a storm. Each panel is flat grey sheet, unpainted, with a jagged edge where it’s split and no manufacturer stamp visible from the yard side. That’s a job for a sample, not a hammer. A lab test runs $88 to $160 per sample, and a small job like this gets priced against the minimum job charge of $800 to $1,500 rather than by the panel, because the setup and containment cost roughly the same whether it’s one sheet or four. What happens after a positive result is in our fence removal guide. If you’re standing over a cracked panel right now, call now before you lever off any more of it.
What a Super Six or corrugated asbestos roof looks like
Corrugated asbestos cement roofing earned the nickname Super Six after Hardie’s Fibrolite brand, though the Asbestos Product Guide notes the name stuck as a generic term for corrugated AC sheeting generally, not just that one product line. The giveaway is the ridge pattern. Early sheets used an 11-ridge profile from the early 1900s, and from the mid-1920s manufacturers including Hardies and Wunderlich moved to a wider, deeper 7-ridge design, which is the profile most people mean when they say Super Six.
Colour varies. Most is left as plain grey cement, sometimes painted, but at least one brand, the Tasbestos Trojan Tile, was produced in a red-brown finish. On a roof that’s been up for decades, weathering shows up as surface flaking, and moss or lichen can work root structures into the surface that let water and air in, which weakens the sheet further. None of that proves it’s asbestos on its own. Modern fibre cement and some steel profiles can look similar from the ground, especially through a phone camera zoomed in from the yard.
Take a Super Six garage roof in Corio that’s started to crack along one ridge after a branch came down in a storm. The sheet is the wider 7-ridge profile, plain grey, with visible fibre bundles at the crack rather than a clean split. Get that tested before anyone goes up a ladder with an angle grinder. A roof this size usually needs more than one sample, because the ridge capping and the sheet itself can be different materials, and each material is tested separately. Once you know what you’re dealing with, our roof removal guide and our Super Six removal article walk through what the job involves.
What asbestos looks like on ceilings: moulded sheeting, sprayed coatings and textured finishes
Ceilings are the least reliable place to trust your eyes. Older asbestos cement ceiling sheeting can look identical to ordinary plasterboard, sold under brand names such as Fibrolite, Durabestos, Tasbestos, Asbestolite, Fibrock, Wunderflex and Versilux, and low-density board variants like Asbestolux, Duralux and Bevelux. Some ceilings from the early to mid-20th century have a moulded pattern pressed into the sheet, in rectangles or diamonds, with the joint lines picked out by timber or asbestos cement cover strips. Later commercial ceilings switched to aluminium jointing strips from the late 1960s, which is a clue about age but not proof either way.
Sprayed coatings are a different animal, and a far more dangerous one. Applied to the underside of roofs, over structural beams and in ceiling voids from the 1930s to the 1970s, the coating is usually white or grey, left rough where it was sprayed on or trowelled smooth afterwards, and it could contain up to 85 percent pure asbestos fibre. It breaks up far more easily than fibro sheeting. A knock, a renovation, or even running a cable through a ceiling void can release a large amount of fibre from material like this.
A textured or heavily patterned decorative ceiling coating is its own question, and it deserves its own answer rather than a guess from a stepladder. Our guide to textured ceiling coatings covers that specifically. If a ceiling in your Geelong home has any of these features and you’re about to run cabling, fit downlights or take a ceiling down for a renovation, book a test before you touch it.
What does asbestos look like inside: vinyl tiles, pipe lagging and other places it hides in plain sight
Indoors, asbestos usually hides behind something else, which is exactly why our guide to where asbestos hides in an old Geelong house covers the room-by-room detail. A couple of forms are worth being able to picture here.
Vinyl floor tiles from the 1950s to the 1970s came in a wide range of colours and patterns, including finishes made to imitate terrazzo, marble and woodgrain, plain colours, and marbled tiles with contrasting feature strips. Asbestos could be in the tile itself, in an asbestos felt backing, or in a black paint-on adhesive underneath, and each is a separate material for testing purposes. A tile that’s whole and sitting under carpet looks like nothing more than an old floor tile. It’s what’s underneath, and what happens when you lever it up, that matters.
Pipe lagging is the other one worth knowing. It’s insulation wrapped around old pressure pipes and heating pipework, sometimes asbestos compounded with magnesium carbonate or sodium silicate, sometimes asbestos paper worked around bends, finished in a calico, canvas or hessian outer wrap that was often painted. It shows up in ceiling voids, underfloor spaces and around older hot water systems, and it degrades with age and temperature cycling. Loose debris around old pipework is a sign to stop and test, not to brush away. More detail is in our pipe lagging guide. If you’d rather not wait on an inspector, our test kit article explains the mail-in option.
Why you can’t identify asbestos just by looking at it
Here’s the part that trips people up. Asbestos Victoria puts it plainly: you can’t tell if a material contains asbestos just by looking at it, and only laboratory testing of a sample can confirm it. Painted sheeting, rendered walls, a plasterboard-look ceiling and a plain floor tile can all still test positive. Equally, a rough grey sheet that matches every fibro description above might turn out to be ordinary fibre cement, because manufacturers have made asbestos-free cement sheet since the 1980s, and the two can be hard to tell apart once both are weathered.
That cuts both ways. Don’t assume the worst about every grey sheet in the yard, and don’t assume a painted or ordinary-looking surface is safe either. The only way to know for certain is a sample analysed by a NATA-accredited laboratory. Our article on how asbestos testing actually works in Victoria walks through the process, and our testing page covers what a sampling visit involves.
The three recognised types, white (chrysotile), blue (crocidolite) and brown (amosite) asbestos, aren’t something you can reliably tell apart by colour in a building material, since the fibres are usually bound inside cement, vinyl or an adhesive rather than sitting exposed. Our guide to the three types of asbestos explains why the distinction matters more for how a job is classified than for how you’d spot it in the yard.
What to do once you think you’ve spotted it
Once you suspect a material might be asbestos, stop asking what it is and start thinking about what you do next. Don’t sand it, drill it, water blast it, dry sweep it or walk on it. Don’t remove more than you were planning to, and don’t put anything you’ve already taken off in the household bin.
| Where you found it | What it typically looks like | Friable or non-friable |
|---|---|---|
| Fence, wall or eaves sheet | Flat grey or painted cement sheet, jagged break | Non-friable while intact |
| Corrugated roof (Super Six) | 7 or 11-ridge profile, grey or red-brown, surface flaking with age | Non-friable while intact |
| Moulded ceiling sheet | Looks like plasterboard, sometimes a diamond or rectangle pattern | Non-friable while intact |
| Sprayed ceiling or beam coating | White or grey, rough or trowelled smooth | Friable, breaks up easily |
| Vinyl floor tile and adhesive | Coloured or patterned tile, black paint-on adhesive underneath | Non-friable while intact |
| Pipe lagging | Calico, canvas or hessian wrap around pipework | Friable once damaged |
Whether you’re allowed to deal with any of this yourself depends on the quantity and where it is, not just what it looks like. Victoria’s rules cap unlicensed removal at 10 square metres of non-friable material and no more than one hour of removal work in any seven-day period, and both caps have to hold. Those rules bind employers and tradespeople at workplaces, and WorkSafe recommends homeowners follow the same limits at their own home, even though the regulations themselves don’t apply there. Our guide to removing asbestos yourself in Victoria sets out exactly where that line sits, and our guide to friable versus non-friable asbestos explains why a sprayed coating is a different category of job to a fence panel.
If a sample comes back positive, disposal has to go to a facility licensed to receive it. In the Barwon region that’s Drysdale Landfill, on (03) 5251 2935, and our disposal guide for the region covers what it will and won’t take. Removal itself is carried out by licensed asbestos removalists we work with, and their WorkSafe Victoria licence number appears on every quote.
If you’re about to start a renovation and you’re not sure what’s behind the wall you’re about to open up, our guide to asbestos before renovating or demolishing in Victoria is worth reading first. And if you’ve already drilled, cut or sanded into something and you’re standing there now wondering what to do, stop and read our guide on what to do if you’ve drilled into asbestos before you do anything else.
Call now to talk through what you’re looking at: (03) 5550 4817. Or send us a photo through the contact form and we’ll tell you whether it’s worth sampling. Either way, the next step is a test, not a guess, and a licensed removalist can give you a quote once you know what you’re dealing with.
Frequently Asked Questions
Can I tell if something is asbestos just by looking at it?
Not reliably. Some forms have recognisable features, like the jagged break on old fibro sheeting or the ridge pattern on a Super Six roof, but painted, rendered or otherwise disguised material gives no visual clue at all. The only way to know for certain is to have a sample analysed by a NATA-accredited laboratory.
What does asbestos look like on a ceiling?
Older asbestos cement ceiling sheeting can look identical to ordinary plasterboard, sometimes with a moulded diamond or rectangle pattern from the early to mid-20th century. Sprayed asbestos coatings on the underside of roofs or over structural beams look different again, usually white or grey, either rough from spraying or trowelled smooth, and far more friable than sheet material.
Is a grey corrugated roof always asbestos?
Not necessarily. Corrugated asbestos cement sheeting, often called Super Six, was produced before 1990 with a distinctive 7 or 11-ridge profile, but modern fibre cement and some steel roofing can look similar from a distance, especially once both are weathered. A laboratory sample is the only way to be sure, and it’s a small cost against getting a roof job wrong.
What should I do if I think I’ve found asbestos in my home?
Stop what you’re doing, and avoid sanding, drilling, water blasting or sweeping the material. Get a sample tested before you go any further, and if it comes back positive, get a quote from a licensed removalist rather than tackling it yourself, especially for anything beyond a small patch.
