Older corrugated cement roofs are common across NSW homes, garages and sheds. Some may contain asbestos, particularly where the building was constructed or renovated decades ago. If an asbestos roof is damaged, weathered or due for replacement, removal needs careful planning and the right controls.

Why asbestos roofing needs specialist handling

Roof sheets can become brittle over time. Walking on them, breaking them, using high-pressure cleaning or cutting them can release fibres. Wind, height and access also make roof work more complex than many other asbestos tasks.

The safest approach is to have the material assessed before any work begins. If asbestos is confirmed, a licensed removal team can determine the appropriate method, equipment and work area controls.

PPE is only one part of the control plan

Proper personal protective equipment is essential for asbestos removal, but it is not the only safeguard. Licensed workers use suitable disposable coveralls, gloves, respiratory protection and footwear controls as part of a broader system of work.

That system can also include controlled access, wet methods where appropriate, careful sheet handling, decontamination procedures and secure waste packaging. The goal is to prevent fibre release rather than relying on PPE alone.

What safe removal looks like

A professional team plans the job before lifting a sheet. They assess access, nearby homes, power lines, weather conditions and the condition of the roof. Sheets are handled to minimise breakage and are not thrown, dropped or cut into smaller pieces.

The work area is managed to keep occupants and bystanders away. Once removed, asbestos waste is wrapped or bagged, labelled and transported for disposal through an approved pathway.

In NSW, removing more than 10 square metres of non-friable asbestos cement roofing requires a Class B asbestos removal licence. For licensed removal work, the removalist must give the regulator the required notice before work starts. A clearance inspection and clearance certificate are required after licensed removal of more than 10 square metres of non-friable asbestos, before the area is returned to normal use.

Avoid common roof mistakes

Do not pressure-clean an older cement roof. Do not drill into it to install solar panels, antennas or new fixtures until it has been assessed. Avoid asking general roofers or handymen to remove suspect sheets without confirming their licensing and asbestos controls.

Even a small shed roof can create a serious risk if the material is broken or handled incorrectly.

Plan replacement work properly

Removing an asbestos roof is often the first stage of a larger project. Arrange the assessment and removal before booking replacement roofing, solar installation or renovation trades. This helps avoid delays and keeps the site safer for everyone involved.

Conclusion

Asbestos roof removal is not a DIY task. With a licensed team, correct PPE, controlled handling and compliant disposal, property owners can replace ageing roofing with a clear plan and less uncertainty.
