How to Tell If Your Roof Has Asbestos: A Sunshine Coast Homeowner’s Guide

If your Sunshine Coast home was built before 1990, its roof may still contain asbestos. Older corrugated cement sheets, roofing shingles and even gutters can contain the material, but appearance alone cannot confirm it. Knowing the clues helps you decide when to arrange testing and whether asbestos roof removal on the Sunshine Coast needs to be considered.

An asbestos roof is made from roofing products that contain asbestos fibres, commonly mixed into cement to strengthen the material. Asbestos cement was used across Australian homes, garages and sheds for decades before asbestos products were phased out. One familiar example is Super Six roofing, the deep-corrugated fibre cement product historically manufactured by James Hardie. It's often grey, with broad waves that can resemble older metal sheets when viewed from the street. The term fibro roof simply describes fibre cement roofing. While many older fibro products contained asbestos, not every fibre cement sheet does.

A property's construction date is a useful early indicator. Asbestos-containing building products were common in Australia before the 1990s, so an original roof from that period deserves closer attention.



A 1970s home could have a recently installed steel roof, while a freestanding shed or carport still has its original asbestos cement sheeting.

If available, look through renovation paperwork, building plans and previous inspection reports. These may identify when particular structures were built or re-roofed.

Old asbestos roof sheets and corrugated metal can seem alike, especially from the ground.

Thicker Corrugated Sheets

Traditional asbestos cement sheets are generally thicker and heavier than thin corrugated steel. Super Six has a noticeably deep wave profile.

A Dull, Chalky Surface

Weathered cement sheets often develop a muted grey finish, staining or a powdery-looking surface. Don't touch the surface to test whether it's chalky.

No Rust, but Heavy Weathering

Steel can rust when its protective coating breaks down. Cement doesn't rust, but older sheets may show erosion, cracks, worn edges or deterioration around fasteners.

Moss and Lichen Growth

Warm, humid conditions on the Sunshine Coast encourage lichen and moss on many roofing materials. Growth on an ageing cement roof may accompany surface deterioration, but it doesn't confirm the presence of asbestos.

Corrugated sheets are only part of the picture. Some older properties also have asbestos roof tiles or shingles made from cement, as well as asbestos-containing guttering and downpipes. These products can be easily overlooked when attention is focused on the main roof. Other places to consider include detached garages, garden sheds, verandahs, carports and additions with older cement roofing. People also ask, what does asbestos roof insulation look like? Some historical insulation materials contained asbestos, but you can't reliably identify them by colour, texture or a photograph. Don't enter a roof cavity or disturb loose insulation to investigate. Seek specialist advice if there's any doubt.

No. Corrugation shape, thickness, colour and weathering may suggest asbestos cement, but none can confirm it reliably. Only laboratory analysis of a representative sample safely collected by an appropriately qualified professional can establish whether asbestos is actually present. Never break off a piece yourself to find out.

Intact, undisturbed bonded asbestos cement is generally considered lower risk because its fibres are held within the cement. The level of concern depends on its condition and whether work or weather could damage it. Ageing asbestos roofing can become more brittle. Surface erosion may release fibres and deteriorated material can collect in gutters, where routine cleaning could disturb it. Cracked sheets, broken edges and loose debris deserve particular care. Sunshine Coast storms introduce another risk. Strong winds, falling branches or flying objects can break older sheets and leave contaminated fragments around a property. If that happens, keep people and pets clear of the affected area and arrange specialist advice instead of collecting debris yourself. An asbestos roof in reasonable condition may not require immediate replacement. What matters is a sound assessment of its condition, likely future disturbance and the work you're planning.

The safest first move is to leave suspected materials undisturbed. Don't try to identify them by breaking off a piece or cleaning the roof to see the surface underneath.

In particular:

• Don't drill, saw, grind or sand suspected asbestos cement
• Don't walk on ageing cement sheets, which may be brittle and unsafe
• Don't pressure-clean the roof or use abrasive blasting
• Don't scrape off moss or lichen
• Don't use a household vacuum to collect suspected asbestos dust
• Don't sweep up storm-damaged fragments or empty contaminated gutters yourself



Queensland explicitly prohibits high-pressure water cleaning of asbestos-containing roofs. It also restricts methods that release fibres, including certain power-tool uses and compressed air. If you have damaged sheets or debris after a storm, prevent access and contact an appropriately licensed asbestos professional for advice on the next steps.

Finding possible asbestos doesn't automatically mean tearing off the roof straight away. Start with a professional assessment of its likely material, condition and any planned renovations. Where confirmation is needed, testing can establish whether asbestos is present. If replacement is recommended, a properly planned project separates asbestos removal from installation of the new roofing. It should address site protection, safe handling, lawful transport and disposal, clearance requirements and the suitability of the replacement material.

At Stormguard Roofing, we provide asbestos roof removal on the Sunshine Coast and help homeowners plan the transition to a new roof. We have over 10 years' experience removing asbestos roofing and more than 25 years' experience in roofing locally. Our stated credentials include QBCC licence 15252624, a WHSQ Class B asbestos removal licence and an environmental waste licence. We also organise asbestos clearance certificates. Our guide to reroofing with an asbestos roof explains further considerations when planning the project. Once the asbestos work and applicable clearance steps are complete, we can discuss roof replacement options to suit your home, including modern metal or tiled roofing.

The main takeaway is straightforward: a pre-1990 roof deserves attention, but its age and appearance can't establish whether it contains asbestos. Avoid disturbing suspicious materials and get qualified advice before arranging cleaning, repairs or renovations. If you're concerned about an older roof, contact Stormguard Roofing to discuss a professional assessment and a clear plan for safe removal and replacement where required.
