Understanding Asbestos Roof Removal Regulations in Perth

Across Perth, and particularly in established Rockingham suburbs such as Safety Bay, Waikiki, Warnbro, Cooloongup and Port Kennedy, many homes, sheds, carports and outbuildings still have asbestos cement roofing. Asbestos was widely used in Australian building products until a national ban took effect on 31 December 2003. If your property was built or renovated before the late 1980s, there is a real chance your roof contains it.

Asbestos roof removal is tightly regulated in Western Australia. Knowing the rules protects your family, your neighbours and your finances, and helps you avoid penalties. This guide explains the key requirements as they stand in 2026.

Why Asbestos Roofing Is Regulated

Asbestos fibres are microscopic. When inhaled, they can cause serious diseases including asbestosis, lung cancer and mesothelioma, often decades after exposure. Most roofing sheets are non-friable (bonded) asbestos cement, which is relatively stable while intact. Over decades, though, weathering, moss growth, hail damage and general deterioration can loosen fibres at the surface. Careless removal, such as breaking sheets, drilling, or using power tools, can release large numbers of fibres into the air.

This is why WA has https://dantellkg731.rivertonbrief.com/posts/what-causes-lichen-and-moss-growth-on-perth-roof-tiles strict laws covering how asbestos is handled, removed, transported and disposed of.

The Key Laws and Regulators in Western Australia

Several pieces of legislation and agencies apply to asbestos roof removal in Perth:

Work Health and Safety Act 2020 (WA) and the Work Health and Safety (General) Regulations 2022: These set licensing, training, notification, safe work and clearance requirements for asbestos removal work.
WorkSafe WA (part of DEMIRS): The regulator that licenses asbestos removalists, receives removal notifications and enforces workplace safety rules.
Health (Asbestos) Regulations 1992: These cover public health aspects such as handling, transport and disposal of asbestos materials.
Department of Water and Environmental Regulation (DWER): Oversees environmental rules for waste, including how asbestos waste is managed and where it can be disposed of.
Local governments, including the City of Rockingham: Can advise on local approvals, waste facilities and any building or planning requirements connected to a roof replacement.

Regulations and codes of practice are updated from time to time, so confirm current requirements with WorkSafe WA before starting a project.

Licensing: Who Can Remove an Asbestos Roof?

WA has two classes of asbestos removal licence:

Class A: Required for removing any quantity of friable asbestos and for removing non-friable asbestos in certain circumstances.
Class B: Required for removing more than 10 square metres of non-friable (bonded) asbestos or asbestos-containing material.

Most residential roofs are far larger than 10 square metres. A typical house roof, or even a double carport or large shed, will usually exceed this threshold. That means asbestos cement roof removal in Perth almost always requires a licensed removalist, and a Class B licence is generally the minimum.

What About DIY Removal?

Under WA rules, a householder may legally remove small areas of bonded asbestos (10 square metres or less) from their own home without a licence. Even then, the same safe work principles apply, and the health risks are the same. Many homeowners find that small jobs are riskier than expected, because roof sheets are brittle, working at height is hazardous, and contamination of the yard, gutters and neighbouring properties is easy to cause. For a whole roof, professional removal is the compliant and safest choice.

Notification, Signage and Site Controls

Licensed removalists must follow strict procedures. These typically include:

Notifying WorkSafe WA in writing before work begins (the standard lead time is at least five days).
Informing neighbours and others who may be affected by the work.
Setting up barricades, warning signs and exclusion zones around the work area.
Using trained workers with current asbestos removal training and a qualified supervisor on site.
Wearing appropriate personal protective equipment, including suitable respirators and disposable coveralls.
Keeping sheets wet or treated with a suitable sealant, and removing them whole, without breaking them.
Setting up decontamination procedures for workers and equipment.

A reputable contractor will explain these steps in the quote and handle the paperwork for you.

Prohibited Practices That Can Lead to Fines

Certain methods are not permitted, or are strongly discouraged, because they release dangerous fibres. These include:

Cleaning asbestos roofs with high-pressure water blasters.
Cutting, drilling, sanding or grinding asbestos sheeting with power tools.
Dry sweeping or using a standard household vacuum to clean up debris.
Breaking or dropping sheets from the roof.
Reusing or selling asbestos sheeting, or stockpiling it on site.

If you have been tempted to pressure-wash a mossy asbestos roof to improve its appearance, don't. It can contaminate the entire property and may breach regulations.

Safe Transport and Disposal

Removing the roof is only part of the process. Asbestos waste must be:

Wrapped and sealed in heavy-duty plastic sheeting (typically 200 micron thickness) and secured with tape.
Labelled with appropriate asbestos warning information.
Transported in a manner that prevents fibre release, usually by a licensed removalist using suitable vehicles.
Disposed of only at a landfill facility authorised to accept asbestos waste, with advance notice to the site and in line with its requirements.

Illegal dumping of asbestos is a serious offence with substantial penalties. It also puts the wider Rockingham community and the environment at risk. Always ask your removalist how and where the waste will be disposed of, and keep any disposal documentation they provide.

Clearance Inspections and Air Monitoring

After asbestos removal, a clearance inspection by a competent person may be required to confirm the area is safe and that no visible asbestos residue remains. This is mandatory for friable asbestos work and is commonly provided for larger non-friable jobs. Air monitoring may also be used on some projects. A clearance certificate gives you a record that the work was done properly, which can be valuable when selling or insuring your property.

How to Choose a Compliant Asbestos Removalist in Rockingham

Because the stakes are high, choose your contractor carefully. Before signing a quote:

Ask to see their current WorkSafe WA asbestos removal licence and verify it.
Confirm they carry public liability insurance and appropriate workers' compensation cover.
Request a written scope of work covering removal, waste disposal, site controls and clean-up.
Ask who will arrange notification to WorkSafe and any clearance inspection.
Check whether the quote includes the replacement roof, or whether you need a separate roofer.
Be cautious of unusually low quotes, which can signal cut corners on safety or disposal.

Planning Your Roof Replacement

Many Rockingham homeowners combine removal with installing a new roof, often Colorbond steel, which is lightweight, durable and well suited to WA's coastal conditions. Coordinating both stages with one provider or a well-organised team reduces delays and limits the time your home is exposed. Also check with the City of Rockingham whether any building or planning approvals apply to your replacement roof, especially if you are changing materials, pitch or structure.

Because asbestos cement roofs can become increasingly brittle with age, planning removal sooner rather than later is often safer than waiting for visible damage or a storm to force the issue. This is especially true for roofs near the coast, where salt air, wind and weathering accelerate deterioration.

Final Thoughts

Asbestos roof removal in Perth is a regulated activity for good reason. For most homes, the law requires a licensed Class B removalist, correct notification, controlled work practices, safe packaging and transport, and disposal at an authorised facility. Following these rules protects your health and your neighbours, and it gives you peace of mind and documentation for the future.

If you suspect your Rockingham property has an asbestos roof, start by having the material identified, then speak with a licensed professional about a compliant removal plan. For the most up-to-date legal requirements, contact WorkSafe WA or the City of Rockingham.
