If you live in an older part of Australia, there’s a real chance you have come across asbestos cement in one form or another. One of the most common is super 6 asbestos, a type of corrugated asbestos cement roof sheeting that was widely used because it seemed like a rugged solution: tough, weather-resistant, and cheaper than many alternatives at the time.
The problem is not the roof sitting there quietly. The problem starts when the material is damaged, drilled, cut, sanded, pressure-cleaned, or broken. That’s when it can release asbestos fibres into the air as asbestos dust, creating a serious health risk.
This guide is written for everyday homeowners and property managers. It explains what super 6 is, where it shows up in Australian homes, what “bonded” and “friable” mean, how asbestos exposure happens, and what Australian safety expectations look like when you need to remove asbestos or replace a roof as part of renovation or construction projects.
What Does “Super 6” Mean and Where Might You Find It?
“Super 6” is a name people commonly use for older corrugated asbestos sheets made from asbestos cement. You may hear it called corrugated asbestos, corrugated asbestos cement, or corrugated asbestos roofing. It is part of a broader group of asbestos cement products that were used across residential and commercial buildings.
You might find super 6 and other asbestos products in places like:
- Roof sheeting on garages, carports, verandas, and older extensions
- Rural sheds and farm buildings
- Sheds, workshops, and old industrial areas near factories
- Old fences and boundary panels made from asbestos cement sheeting
- Walls or eaves lining made from flat sheets or cement sheet
- Lining in ceiling spaces, under eaves, or behind old cladding
- Older pipes and service penetrations where asbestos cement was used for heat and wear resistance
People also use the word fibro or fibro cement when talking about older sheet products. Not all fibro is asbestos, but older asbestos fibre cement is common in properties built decades ago.
What Does Super 6 Look Like in Real Life?
Super 6 is usually a grey cement-based sheet with a corrugated profile. Over time it can become painted, weathered, or discoloured. Some sheets have a texture people describe as a golf ball pattern or small dimples on an otherwise smooth surface. That texture alone is not proof, but it can be one clue.
If you are unsure, treat it as asbestos until proven otherwise. Guessing wrong is not worth it.
Why Are Asbestos Fibres a Health Risk?
Asbestos is made of tiny fibres. When disturbed, asbestos fibres can become airborne and be breathed in. This is the core danger of asbestos exposure.
Long-term health outcomes linked to inhaling fibres include asbestos related diseases such as:
- Mesothelioma
- Lung cancer
- Asbestosis and other chronic respiratory conditions
One tricky part is timing. Many asbestos-related health problems do not show up straight away. People can feel fine for years after exposure, which is why prevention matters more than “seeing how you go.”
Exposure risk increases when asbestos cement becomes damaged or degraded. That is why an old, brittle roof in poor condition is more concerning than well-kept, sealed sheeting that has not been disturbed.
How Can You Tell If Your Corrugated Roof or Cement Sheet Might Contain Asbestos?
You cannot confirm asbestos just by looking, but you can spot common situations where asbestos is more likely.
Ask yourself:
- Was the property built or renovated before the early 2000s?
- Do you have older building materials like corrugated roofing, old flat sheet cladding, or fencing panels?
- Is the sheeting cracking, flaking, or breaking down from weathering?
- Has anyone drilled it for antenna mounts, solar brackets, pergolas, or new gutters?
You may also see it in older product types like:
- AC sheet (a common shorthand people use)
- Old asbestos cement sheeting used as eaves, soffits, and wall lining
- Older cement-based boards sometimes described historically as “asbestos lumber” in old catalog language, meaning board-like pieces used around trims and edges
What Should You Avoid Doing While You’re Figuring It Out?
If there is any chance it is asbestos, avoid:
- Cutting or drilling
- Sanding, grinding, scraping, or using power tools
- Pressure washing (this can spread fibres widely)
- Pulling sheets up “just to check”
- Sweeping up debris dry (dry sweeping can lift fibres into the air)
These actions can create dust, break bonded asbestos into smaller fragments, and push fibres into the air around your home and neighbours.
When Is Asbestos Cement Considered Bonded or Friable?
This matters because Australian rules treat these categories differently.
Bonded asbestos is asbestos bound tightly in a matrix, like asbestos cement sheeting. Super 6 typically falls into this category when it is in good condition. The fibres are trapped in the cement and not easily released unless the sheet is damaged.
Friable asbestos is material that can be crumbled or reduced to powder by hand pressure, or has become so degraded that fibres can be released more easily. Weathered, cracked, broken, or heavily damaged asbestos cement can start behaving more like friable material, especially if it has been repeatedly disturbed.
In practical terms:
- Bonded does not mean “safe to mess with”
- Friable means “stop and get licensed professionals involved”
If you are dealing with an older roof and it is clearly deteriorating, treat it with extra caution.
What Do Australian Regulations Expect You to Do Before You Start Work?
Australia has clear expectations through work health and safety laws and approved codes of practice. Even when the property is residential, asbestos removal and demolition-related work can fall under regulated safety duties, especially when trades or contractors are involved.
In plain language, the expectations usually come down to this:
- Identify the risk before you start
- Prevent fibres from getting into the air
- Use the right level of licensing and training for the job
- Use proper containment, clean-up, and disposal pathways
- Do not create exposure for workers, occupants, or neighbours
Different states and territories can apply extra requirements (for example, some locations are stricter about air monitoring or specific removal steps). If you are hiring someone, they should be the one making sure the plan meets local requirements, including any demolition standards that apply.
How Should You Manage a Suspected Asbestos Cement Roof Without Disturbing It?
If you suspect asbestos roofing but you are not removing it today, the goal is to keep it stable and sealed so it does not shed fibres.
Good risk-reduction steps include:
- Keep people off the roof
- Do not store items on it or lean ladders directly against sheets
- Avoid any work that penetrates the sheet (no new mounts, no drilling)
- Keep gutters clear using safe methods that do not grind or break the sheeting
- If it is painted or sealed, do not sand or scrape the surface
- Treat cracks or breaks as urgent, because broken edges can release fibres more easily
If the roof is deteriorating, replacement is usually the long-term fix. Patchwork can become risky if it involves disturbance.
What Is the Safest Way to Remove Asbestos From a Roof?
For most households, the safest approach is simple: do not DIY. A professional approach reduces risk to you, your family, and nearby homes.
A well-run removal plan generally focuses on controlling dust, preventing breakage, and disposing of material correctly. This is especially important when removing a corrugated asbestos cement roof because sheets can crack easily if handled poorly.
What Does “Safe Removal” Usually Involve?
While the exact method depends on your site, safer removal commonly includes:
- A clear work area with restricted access
- Wet methods to reduce airborne asbestos dust
- Removing whole corrugated sheets intact where possible
- No high-speed cutting tools that can spread fibres
- Correct PPE and decontamination steps
- Careful packaging, labelling, and transport to approved disposal facilities
If you are doing a larger renovation, demolition, or broader construction scope, you also want the work sequenced correctly so asbestos is dealt with before other trades start.
What Are the Biggest Mistakes That Create Exposure?
These are the common actions that can release asbestos fibres quickly:
- Snapping sheets to “make them easier to carry”
- Using grinders or saws
- Dry sweeping debris
- Tossing broken pieces into open bins
- Letting debris fall into soil, gardens, or on driveways where it can be tracked inside
Even small breakage can create fibres. That is why removal should be planned and controlled.
What Should You Replace Asbestos Roofing With After Removal?
Once asbestos cement is removed, most people want a replacement that is durable, low-maintenance, and suitable for Australian conditions.
A modern re-roof is also a chance to fix other issues you may have been living with, like poor drainage, heat build-up, and condensation.
If you are looking at a full changeover, these pages can help you understand options and next steps for a safer upgrade:
- Consider a complete roof replacement in Brisbane when the existing corrugated asbestos cement roof is near end of life.
- If your project is a broader upgrade, re-roofing can be the clean “remove and replace” approach many homeowners choose.
- For metal replacement options, Colorbond roofing in Brisbane is often selected for long-term durability in local conditions.
- Another option many people compare is Zincalume roof replacement, especially when balancing cost and performance.
How Can You Improve Comfort and Ventilation During a Re-Roof?
Asbestos removal is about safety, but the rebuild is about making the home better than it was.
Two upgrades that matter a lot in Australia are insulation and airflow:
- Adding or upgrading roof insulation in Brisbane can help with comfort and energy use, especially in hot summers.
- Improving airflow with roof ventilators in Brisbane can reduce heat build-up and moisture problems.
If you are already investing in replacement, it is usually smarter to plan these upgrades at the same time rather than retrofitting later.
Why Should You Think About Gutters and Downpipes at the Same Time?
Older asbestos roofs often sit above older drainage systems. If you are replacing the roof, it is a good time to check gutters, fascia, and downpipes because access is easier and the whole system works together.
You can also fix issues that cause water damage to eaves, walls, and foundations.
Helpful pages for planning that part of the job include:
- If your roof has ongoing leaks or edge rusting (common around old sheeting), metal roof repairs may be part of the broader plan once asbestos has been safely handled.
- For larger sites or business premises, commercial guttering planning can prevent overflow and stormwater issues.
- If your drainage is failing at ground level, downpipe replacement helps move water away from the property properly.
- If you are upgrading edge detailing, fascia capping in Brisbane can tidy up roof lines and protect timber.
- To reduce maintenance and blockages, gutter guard can help keep debris out.
- If the system is simply past it, gutter replacement in Brisbane is often done alongside a full re-roof.
How Do You Handle Condensation and Sarking Once You Move to Metal?
When you move from asbestos cement to metal roofing, you may notice different condensation behaviour. Metal can cool quickly overnight, which can lead to moisture issues if the roof build-up is not designed well.
If you want to understand the issue and the fixes, these are useful reads:
- Learn what drives moisture build-up in metal roof condensation.
- For broader planning, this roof sarking guide for Australian homes explains why sarking and correct layers matter.
This is especially relevant for homes with tight ceiling spaces, newer insulation, or changes to ventilation.
What If Your Home Is Outside Brisbane and You Still Want Guidance?
Many of the same principles apply across nearby regions. If you are comparing repair and replacement pathways, these pages can help with practical context:
- See real-world repair context in about metal roof repairs in Ipswich.
- If stormwater performance is a problem, gutter replacement for Ipswich homeowners covers common reasons people upgrade.
- If you want the “done properly” checklist mindset, new roofs done right is a helpful starting point.
What Should You Do After the Work to Reduce Ongoing Risk?
Once asbestos has been removed and replaced, your risk drops dramatically, but it is still worth being careful about any remaining suspect materials around the property.
Post-project best practice includes:
- Keep documentation of what was removed and when
- If other areas still contain asbestos cement products (like fences, flat sheets, or old internal lining), plan future work carefully
- Avoid drilling old cement sheeting in sheds or eaves unless it is confirmed asbestos-free
- If you ever find debris, do not dry sweep it. Treat it as suspect material and handle it safely
Remember: asbestos management is not just about the roof. It can appear in walls, old fibro panels, cement sheet lining, and older service areas around pipes.
What Is the Bottom Line on Super 6 Asbestos?
Super 6 asbestos and other asbestos cement products are a legacy issue in Australia. In many homes, the sheeting has sat there for decades without causing problems. The real risk begins when you disturb it and create asbestos dust that can be breathed in.
If you take one thing from this guide, let it be this: do not rush. Treat any suspected corrugated asbestos cement roof as asbestos until confirmed otherwise. Plan the job properly, follow Australian safety expectations, and choose a replacement approach that improves the home for the long term.

What Are the Most Common Questions About Super 6 Asbestos?
Can I safely live under a super 6 asbestos roof if it is not damaged?
In many cases, yes, because it is usually bonded asbestos cement and fibres are not easily released when the sheets are intact. The key is not disturbing it. Problems begin when drilling, cutting, breaking, or pressure-cleaning creates asbestos dust and airborne fibres.
Is it legal to remove a small amount of bonded asbestos myself in Australia?
Rules vary by state and territory, and licensing thresholds can apply. Even where small amounts may be allowed, the safest choice is still to use trained professionals because mistakes can expose you, neighbours, and anyone who later handles the waste.
What is the fastest way to reduce risk if my corrugated asbestos sheets are deteriorating?
Stop any work that could disturb the material, restrict access, and arrange an assessment. If the sheeting is brittle, cracked, or breaking down through weathering, replacement is often the safer long-term decision.
Should I replace gutters and downpipes when replacing an asbestos roof?
It is often a smart move. Roofing, gutters, fascia, and downpipes work as one system. Doing them together can prevent leaks, overflow, and future rework, and it reduces the need for later trades to access roof edges again.
How do I prevent fibres from spreading if I find broken pieces on the ground?
Do not dry sweep or use a blower. Treat it as suspect asbestos material. Keep people away, lightly wet it to reduce dust, and have it collected and disposed of using safe methods that prevent fibres getting into the air.
