Older Sydney homes can contain asbestos cement roofing, particularly properties built or renovated several decades ago. While intact bonded asbestos may present a lower risk, cutting, breaking, drilling, or damaging the material can release harmful fibres. If you suspect your home has asbestos roofing, it is important to avoid disturbing it and get appropriate professional advice before starting roof work.
How to Identify Potential Asbestos Roofing
Asbestos was widely used in corrugated roofing and cement sheeting in older Australian homes. However, you cannot confirm its presence based on appearance alone. If you suspect your roof may contain asbestos, have it assessed before starting any work.
Before disturbing a suspected asbestos roof:
Do not drill, cut, sand, or break the roofing material.
Avoid pressure washing or using power tools on the surface.
Arrange a professional assessment if repairs or replacement are planned.
Follow appropriate safety and disposal requirements if asbestos is confirmed.
Getting the roof assessed first can help determine the safest approach for repairs, renovation, or complete roof replacement.
When Residential Asbestos Roofing May Need Removal
Removal may be considered when roofing is damaged, deteriorating, or being replaced as part of a renovation. The work needs careful planning because disturbing asbestos can create exposure risks.
In NSW, the requirements depend on the type and amount of asbestos involved. More than 10 square metres of non-friable asbestos generally requires a licensed asbestos removalist, while any amount of friable asbestos requires licensed removal. Safe handling and disposal requirements also apply.
A professional removal process can include:
Assessing the roof and work area
Planning safe removal and site controls
Carefully removing and containing roofing materials
Transporting asbestos waste to an appropriate disposal facility
Choosing the Right Approach for Your Home
Residential asbestos roofing should not be treated like an ordinary roof repair. The condition of the material, amount involved, access to the roof, and planned replacement work can all affect what needs to be done.
If you suspect asbestos roofing on your residential Sydney property, avoid disturbing the material and speak with a suitably qualified professional. Getting the right advice before work begins can help protect household members, workers, and neighbours.
