Asbestos was once a popular building material in Australia, prized for its durability, fire resistance, and insulation properties. However, its health risks led to strict regulations and a nationwide ban.
If your home was built before the 1990s, there’s a chance that asbestos-containing materials (ACMs) were used in its construction—including in your roof tiles. Many of these roof tiles were made from asbestos cement, which often resembles slate. Identifying asbestos in roof tiles and correct asbestos roof removal is crucial for ensuring your property is safe and compliant with Australian regulations.

What are asbestos roof tiles?
Asbestos roof tiles are a type of roofing material that was widely used in the construction industry from the 1940s to the 1990s. These tiles are made from a mixture of asbestos fibres and cement, which provides durability, water resistance, and heat insulation. Designed to resemble slate tiles, asbestos roof tiles are typically smooth and flat, making them a popular choice for both residential and commercial properties due to their affordability and hard-wearing nature.
However, due to growing health concerns, asbestos use in building materials was phased out in the late 1980s, and a complete ban on the manufacture, import, and use of asbestos came into effect in Australia on 31 December 2003. As a result, identifying and managing asbestos roof tiles is crucial for maintaining a safe living environment.

How to identify asbestos in roof tiles
Determining whether your roof tiles contain asbestos isn’t easy without professional testing. However, there are a few key indicators to consider:
Age of the property
If your roof was installed or renovated before 1990, there is a significant likelihood that asbestos was used in the materials.
Appearance and texture
Asbestos-containing roof tiles were typically made of cement bonded with asbestos fibres. They often have:
- A rough, grainy texture
- A fibrous or layered appearance
- A cement-like density
- Corrugated or flat shapes, often seen in garages, sheds, or older homes
Lack of manufacturer markings
Some newer, non-asbestos roof tiles may have a manufacturer’s stamp indicating that they are asbestos-free. However, older tiles are unlikely to have any clear markings, making professional testing necessary.
Condition of the roof tiles
If the tiles appear damaged, cracked, or are deteriorating, they may be releasing harmful asbestos fibres into the air, making asbestos roof tiles dangerous. Asbestos is most dangerous when disturbed, so avoid touching or breaking suspect tiles.
Health risks of asbestos in roof tiles
Asbestos fibres, when airborne and inhaled, can cause serious and often fatal illnesses. These include:
- Mesothelioma: A rare and aggressive cancer affecting the lungs or abdomen
- Asbestosis: Scarring of lung tissue, leading to breathing difficulties
- Lung Cancer: Increased risk from prolonged exposure to asbestos fibres
Blue and brown asbestos are more harmful than white asbestos. Understanding the different types of asbestos and their health risks is crucial.

What to do if you suspect asbestos in your roof tiles
If you suspect your roof tiles contain asbestos, follow these steps:
1. Do not disturb the tiles
Avoid touching, breaking, or attempting to remove them yourself. Disturbing asbestos materials can release harmful fibres into the air.
2. Arrange for professional testing
A licensed asbestos removal specialist can conduct an asbestos inspection and sample test (if required) to confirm whether your roof tiles contain asbestos. Sample testing involves taking a small tile sample and analysing it in an accredited laboratory. However, it is not always required, as most of the time, asbestos in roof tiles is visible to a licensed asbestos professional.
3. Consider asbestos removal or management
If asbestos is confirmed, you have two options:
- Encapsulation: If the tiles are in good condition, they may be sealed with a protective coating to prevent fibres from becoming airborne.
- Professional removal: If the asbestos roofing tiles are deteriorating, a licensed asbestos contractor is the safest and most compliant option for removing them. Property owners often choose to remove asbestos roofing tiles due to their composition and the issues that arise when damaged.
Asbestos removal costs and considerations
Hiring professionals to remove asbestos roof tiles is crucial to ensure safety and compliance with regulations. The cost of removing asbestos roof tiles can vary based on several factors, including the size of the roof, the height for access purposes, and the type of asbestos present. Typically, the removal process involves measuring the roof size and height to determine the overall cost. Access to asbestos-tiled roofing is usually achieved via a ladder or fixed scaffolding, which is factored into the removal cost.
For instance, the minimum area of asbestos roof tiles that require removal is generally around 75 square meters. The costs include setting up the working area, safety equipment, materials, and disposing of asbestos waste. However, it’s important to note that these costs do not cover reinstatement work, meaning the building will not be watertight after the removal.

Asbestos roof replacement options
When replacing a roof containing asbestos, upgrading to new roofing tiles is often the best course of action. There are several replacement options available, each offering unique benefits:
- Fibre-cement roofing: Known for its durability and affordability, fibre-cement roofing is a popular choice for many homeowners.
- Metal roofing: Offering a modern and sleek appearance, metal roofing is another excellent option that provides long-lasting protection.
- Clay tile roofing: Is a viable alternative for those seeking a traditional, timeless look.
Tip: Consider incorporating insulation materials such as fibreglass batts or reflective insulation that can significantly improve energy efficiency and reduce heat transfer, making your home more comfortable and cost-effective in the long run.
