What Is an Asbestos Roof & How to Identify One on Your Brisbane Home
Many Brisbane homes, particularly those built between the 1940s and late 1980s, were constructed using asbestos cement sheeting for roofing. This highly durable and once-popular building material, often referred to as fibro, is a mixture of cement, sand, and asbestos fibres. The resulting product, asbestos cement, was affordable, fire-resistant, and well-suited to Queensland’s climate, making it a common choice for decades.
To better understand the process of managing this material, this video provides a helpful overview of asbestos roof removal and replacement:
Common Visual Characteristics of Asbestos Roofing
While only professional testing can confirm the presence of asbestos, there are several visual clues you can look for from a safe distance. An older asbestos roof often has a distinct appearance:
- Corrugated Profile: The most common style is a deep, wavy corrugated sheet, famously known by brand names like ‘Super Six’. The ridges are typically larger and more rounded than modern metal roofing.
- Weathered Appearance: The sheets are thicker than metal and have a dull, non-reflective matte finish. Over time, they often appear weathered and grey, sometimes with a mottled pattern or significant lichen and moss growth.
- Underside Texture: If visible from the ground, the underside of the sheeting may have a dimpled or honeycomb-like pattern pressed into it.
- Flat Sheets: In addition to the roof, look for flat, fibrous cement sheets used for the eaves, gables, or wall cladding, as these were often made from the same material.
Why Professional Identification is Crucial
It is extremely difficult for an untrained eye to distinguish between an asbestos cement roof and a modern, non-asbestos fibre cement product. Attempting to break off a piece for a closer look is incredibly dangerous, as this can release harmful fibres into the air. For this reason, if your home was built or renovated before 1990, the safest and most reliable approach is to assume your roof contains asbestos until it is professionally assessed.

Understanding the Risks: When is an Asbestos Roof a Danger?
Many Brisbane homeowners feel a sense of unease when they learn their property has an asbestos roof. However, it’s important to understand that the presence of asbestos-containing material doesn’t automatically mean there is a danger. Most asbestos roofing in Australia is ‘non-friable’ or ‘bonded,’ meaning the asbestos fibres are mixed with cement and are stable when left undisturbed.
The real risk arises when these materials are damaged, deteriorated, or disturbed. When the bonding agent breaks down due to age or impact, microscopic asbestos fibres can be released into the air, where they can be inhaled and pose a serious health risk. Activities that break the surface are particularly hazardous.
To keep your family and neighbours safe, the following activities must be strictly avoided:
- Drilling, sawing, or cutting the sheets
- Sanding or grinding the surface
- Using abrasive power tools or wire brushes
- Aggressive cleaning, especially with high-pressure water
Signs of a Deteriorating Asbestos Roof
A visual inspection can help you identify potential problems. If you notice any of the following signs from a safe distance on the ground, it’s time to consult a professional. Look for significant cracks, breaks, or severe weathering on the sheets. Pay close attention to crumbling edges or corners and any visible exposed fibres, which can look like fine white threads. Heavy moss or lichen growth can also be a red flag, as it traps moisture and accelerates the decay of the cement matrix.
The Dangers of High-Pressure Water Blasting
Attempting to clean an asbestos roof with a high-pressure water blaster is not only extremely dangerous but also illegal. This practice is strictly prohibited under Queensland asbestos regulations because of the severe health risks involved. The intense force of the water jet shatters the surface of the asbestos cement, releasing millions of harmful fibres into the air. This can lead to widespread contamination of your property, your garden, and even your neighbours’ homes. Safe cleaning requires specialised, low-pressure techniques performed only by licensed professionals.
Your Options: Asbestos Roof Restoration vs. Full Replacement
When you discover you have an asbestos roof, it’s natural to feel concerned. However, it’s important to know that you have safe, reliable, and government-approved options. The best path forward depends on three key factors: the current condition of your roof, your budget, and your long-term plans for the property. The decision typically comes down to two professional approaches: full removal or restoration (also known as encapsulation).
Option 1: Full Roof Removal and Replacement
This is the most permanent solution, as it completely removes the asbestos-containing material from your property. It is the only choice if your roof is severely damaged, structurally unsound, or leaking extensively. The process is highly regulated for safety and involves:
- Hiring a licensed Class A or B asbestos removalist to safely dismantle and wrap the roofing sheets.
- Transporting and disposing of the material at an approved facility.
- Installing a brand-new roof with modern materials like Colorbond steel.
While this provides ultimate peace of mind, it is also the most expensive option, often costing tens of thousands of dollars. The work is also significantly more disruptive to your household. For detailed regulations and safety advice, the Queensland Government’s guide for homeowners is an excellent resource.
Option 2: Professional Asbestos Roof Restoration (Encapsulation)
For an asbestos roof that is in fair to good structural condition, professional restoration is an extremely effective, safe, and cost-efficient alternative. Rather than removing the asbestos, this meticulous process involves treating and sealing the entire surface. This locks in the dangerous fibres, preventing them from becoming airborne and posing a health risk.
The key benefits of restoration include:
- Significant Cost Savings: Typically a fraction of the cost of a full replacement.
- Enhanced Safety: The encapsulation process makes the roof safe by preventing fibre release.
- Minimal Disruption: The work is completed far more quickly and with less intrusion than a full removal.
- Improved Appearance: A restored roof looks fresh and modern, boosting your home’s kerb appeal and value.

The Safe Asbestos Roof Restoration Process Step-by-Step
Many Brisbane homeowners worry about disturbing their asbestos roof, and rightly so. However, a professional restoration process is designed with safety as the absolute priority. At Brisbane Roof and Paint, we follow a meticulous, multi-stage procedure that revitalises your roof without the risks associated with disturbance or removal. This proven method not only protects your family but also extends the life of your roof for many years to come.
Stage 1: Safety Preparation and Gentle Cleaning
Our process begins with thorough site preparation. We lay heavy-duty ground covers to protect your garden and pathways and seal your downpipes to contain all water run-off. Next, we apply a specialised fungicidal wash to eliminate any mould, lichen, or algae. The cleaning itself is performed with a controlled, low-pressure water system, a technique specifically designed to gently wash the surface without abrading it or releasing any harmful fibres.
Stage 2: Meticulous Repairs and Priming
With a clean and prepared surface, our experienced technicians conduct any necessary repairs. This involves carefully sealing fine cracks or, where required, replacing broken sections in line with strict industry safety standards. We then apply a high-quality penetrating primer. This crucial coat soaks deep into the asbestos cement sheeting, binding loose surface particles and creating a stable, perfectly prepared foundation for the final protective membrane.
Stage 3: Application of Protective Top Coats
The final stage is encapsulation. We apply at least two thick coats of a premium, flexible roof membrane using an airless sprayer. This creates a seamless, durable, and completely waterproof barrier that fully encases the original asbestos material, locking it safely away from the elements. Not only does this provide the ultimate layer of protection, but it also transforms the appearance of your home, giving you a beautiful, modern-looking roof in the colour of your choice.
This thorough and professional process proves that an old asbestos roof can be made safe, secure, and aesthetically pleasing without the need for a costly replacement. It’s about using the right techniques and premium products to deliver quality you can trust. If you’d like to learn more about our safe restoration services, the experienced team at Brisbane Roof and Paint is here to help.
Queensland Regulations: What Brisbane Homeowners Must Know
Navigating the responsibilities of owning a property with an asbestos roof in Brisbane requires a clear understanding of Queensland’s laws. These regulations, overseen by bodies like Workplace Health and Safety Queensland (WHSQ), are designed to protect you, your family, and the community from the serious health risks of asbestos exposure. As a homeowner, you have a duty of care to ensure any work on your property is managed safely and in full compliance with the law.
DIY Work vs. Professional Services
Queensland regulations permit a homeowner to remove up to 10 square metres of non-friable (bonded) asbestos without a license. However, this rule is not intended for large-scale or high-risk jobs like roofing. Attempting DIY removal on a roof is exceptionally dangerous due to the risks of falls and widespread fibre release if a sheet breaks. Furthermore, it is strictly prohibited to use power tools, drills, sanders, or high-pressure water blasters on any asbestos-containing material, as these actions release dangerous fibres into the air.
Choosing a Qualified Contractor in Brisbane
When it comes to your asbestos roof, engaging a professional is not just the safest option—it’s a legal necessity for any significant work. Choosing the right contractor is critical for ensuring the job is done correctly and safely. Before hiring anyone, we recommend you verify the following:
- Licensing: Ensure they hold the correct licenses from the Queensland Building and Construction Commission (QBCC) and a specific asbestos removal licence (Class A or B).
- Experience & Safety: Ask about their specific safety procedures for asbestos work. A reputable contractor will be transparent about their methods for containment, decontamination, and compliant disposal. Look for a specialist with proven experience, not a general tradesperson.
- Insurance: Confirm they have comprehensive public liability insurance that specifically covers asbestos-related work.

Frequently Asked Questions About Asbestos Roofs
Can I legally paint my own asbestos roof in Brisbane?
While homeowners in Queensland can perform very minor work on asbestos, painting an entire roof is not recommended and can be illegal if not done correctly. The critical issue is preparation; any cleaning or sanding that disturbs the surface can release dangerous fibres. For the safety of your family and neighbours, this work should only be handled by a licensed professional who follows strict safety protocols for working with asbestos-containing materials. This ensures a safe process and a quality, long-lasting result.
How much does asbestos roof restoration cost compared to a full replacement?
A professional restoration is significantly more cost-effective than a full replacement. A complete replacement can cost A$15,000 to A$30,000 or more, due to the high cost of specialist removal, disposal, and new materials. In comparison, a thorough restoration—which includes professional cleaning, repairs, and encapsulation with a premium membrane coating—is a fraction of that price. This makes restoration an excellent, budget-conscious solution for making your roof safe and extending its life.
How long does a professionally restored and sealed asbestos roof last?
When completed by an experienced team using premium-quality sealing membranes and coatings, a restored asbestos roof can have its life extended by 10 to 15 years. The durability of the finish is directly linked to the quality of the preparation and the products used. Our thorough process of cleaning, repairing, and applying a thick, protective membrane ensures the asbestos is safely encapsulated and the roof is protected from the harsh Brisbane climate, providing you with long-term peace of mind.
Is a sealed asbestos roof safe for collecting rainwater?
Absolutely. Once an asbestos roof has been professionally cleaned and sealed with a high-quality, potable water-safe membrane, it is perfectly safe for collecting rainwater. The encapsulation process creates a durable, inert barrier over the entire surface. This barrier prevents any asbestos fibres from contacting the water, ensuring the runoff collected in your tanks is as clean and safe as it would be from any other modern roof surface. It’s a reliable way to make your roof functional again.
What happens if my neighbour illegally pressure washes their asbestos roof?
High-pressure washing an asbestos roof is illegal and extremely dangerous, as it releases a high concentration of harmful fibres into the air which can drift onto your property. If you witness this, your first priority is safety: go indoors and close all windows and doors. You should then immediately report the incident to your local Brisbane City Council or to Workplace Health and Safety Queensland (WHSQ). They are equipped to handle these situations and enforce safe practices.
Does restoring an asbestos roof add value to my property?
Yes, a professional restoration adds significant value to your property. Aesthetically, it improves street appeal by giving your home a modern, clean finish. More importantly, it addresses a major safety concern for potential buyers. A certified, safely encapsulated asbestos roof is a huge positive on a building and pest report, demonstrating that the property has been well-maintained and removing a common barrier to a successful sale. It provides assurance and confidence to prospective buyers.
