If you own or look after an older Australian property, you have probably wondered how to identify asbestos sheeting without putting yourself or your family at risk. Many older buildings across the country still contain asbestos cement sheeting, corrugated asbestos cement sheets, and other asbestos containing materials that were once popular building materials because of their strength, fire resistance and insulating properties. Today we know these asbestos materials carry significant health risks, so understanding where they might be present and what to do about suspect asbestos is critical.
This article explains how to identify asbestos sheeting in a practical way, while keeping in line with Australian building and work health and safety regulations. It focuses on visual characteristics, common locations in residential and commercial buildings, and the limits of visual identification. It also highlights why precise analysis and testing are essential, and how the roofing and guttering services at fortified.com.au can help you move towards asbestos free, safer roofs and external wall cladding without breaching asbestos laws.
Before we dive in, remember that asbestos is a prohibited, hazardous material in Australia, and disturbing asbestos containing products is never a simple DIY job. The safest approach is to treat any suspect material with care, leave it undisturbed, and engage qualified professionals for asbestos removal, testing and roof work in line with the relevant codes of practice.
Why Is It So Important To Know How To Identify Asbestos Sheeting In Australia?
For decades asbestos cement sheet products and other asbestos containing materials were used in Australian construction because they were cheap, tough, and offered good heat resistance, fire resistance and insulating properties. They were installed in roofing, walls, ceilings, external cladding, wet areas, sheds, garages and even some floor coverings. Many older buildings still contain asbestos sheets and other asbestos products, especially homes and industrial buildings constructed or renovated prior to the late 1980s and before the national ban in 2003.
The problem is that asbestos fibres are tiny fibres that can become airborne when asbestos and fibre cement products are cut, drilled, sanded, broken or otherwise exposed. Once inhaled, these dangerous fibres can lodge deep in the lungs. Over time, asbestos exposure can lead to serious health hazards, including:
- Asbestosis
- Lung cancer
- Mesothelioma, a highly aggressive cancer linked to asbestos exposure
These diseases are why asbestos containing products are treated as hazardous materials and why Australian regulations treat any unnecessary exposure as an unacceptable health risk.
Learning how to identify asbestos sheeting is not about becoming an expert who can confirm if a material contains asbestos just by looking at it. Instead, it is about recognising suspect material so you can avoid disturbing it, arrange proper testing, and choose safer options such as asbestos removal by licensed contractors combined with modern roofing solutions from fortified.com.au.
Where Are Asbestos Sheets Commonly Found In Older Buildings?
If you want to identify asbestos safely, a good starting point is understanding common locations. In many older properties and many older buildings across Australia, asbestos containing materials were installed wherever a durable fibre cement or cement sheet product made sense.
Typical locations include:
- Roofing
- Corrugated asbestos sheets on older sheds, carports and industrial buildings
- Corrugated asbestos cement sheets used as roofing on residential and commercial buildings
- External wall cladding
- Flat sheets of asbestos cement sheeting used as external cladding on older properties
- External wall cladding on extensions and garages
- Internal linings and wet areas
- Cement sheet backing in bathrooms, laundries and other wet areas
- Walls and ceilings in older buildings, especially around showers and splash zones
- Other common locations
- Eaves, gables and soffits
- Internal and external walls in sheds
- Some floor coverings and underlay, particularly old vinyl tiles laid over fibre cement
- Certain types of insulation around heaters, hot water services and flues
In many cases these asbestos materials look like ordinary building materials. Because asbestos containing materials were used so commonly in construction, any flat sheets or corrugated products in older homes can be suspect asbestos until proven otherwise.
What Visual Characteristics Can Help You Identify Asbestos Cement Sheeting?
Even though only laboratory testing can give a precise analysis of whether a material contains asbestos, there are some visual characteristics that can help you spot asbestos cement sheeting and similar asbestos cement sheet products so you know when to be cautious.
What Does Asbestos Cement Sheeting Look And Feel Like?
Traditional asbestos cement is usually a mixture of cement and asbestos fibres. In many cases, asbestos cement sheeting and related asbestos products:
- Are white to grey in colour
- Have a hard, dense feel compared to softer plasterboard
- May feel quite brittle at the edges when damaged
- Often appear as flat sheets nailed or screwed onto timber framing
- Can be painted, textured or covered by other materials
Some asbestos cement sheeting has a distinctive pattern. For example, certain asbestos cement sheet products have a dimpled texture on the back that looks a little like a golf ball. This golf ball style pattern is a known sign that the material may contain asbestos.
You may also see moulded battens over sheet joins, or metal strips covering gaps between sheets. None of these features let you identify asbestos with certainty, but they are clues that the material might be asbestos cement.
How Do Corrugated Asbestos Sheets Differ From Modern Fibre Cement Sheets?
On older roofs, corrugated asbestos cement sheets were popular for sheds, industrial buildings and some residential and commercial buildings. These corrugated asbestos sheets can look similar to modern fibre cement sheets or even some non asbestos roofing products.
Some general pointers:
- Older corrugated sheets installed in many older buildings before 1990 are more likely to be asbestos containing materials
- Modern fibre cement sheets are manufactured to be asbestos free, but you cannot rely on looks alone to tell them apart
- Newer products may have clearer manufacturer markings stamped on the surface, while older sheets might not
In practice, you cannot identify asbestos simply by comparing older roofing with modern fibre cement sheets. If the construction date suggests asbestos containing products might be present, you should treat the corrugated sheets as suspect material and arrange testing.
What Other Clues Suggest A Material Contains Asbestos?
Because visual identification is not perfect, Australian guidance suggests using several lines of evidence when trying to identify asbestos containing materials.
Key clues include:
- Age of the building
- If the building or area was constructed or renovated prior to the late 1980s, there is a higher chance the material contains asbestos
- Homes and sheds renovated prior to the early 2000s may also still include asbestos containing products
- Location and use
- Asbestos cement was commonly used in wet areas, as external cladding, and in roofs and eaves
- Many older buildings used asbestos cement sheet products around laundries, toilets, and utility rooms
- Type of material
- Hard, brittle cement sheet, especially in flat sheets or corrugated profiles, is more likely to be asbestos cement
- Backing boards behind old tiles and some older floor coverings can also be asbestos containing materials
- Condition of the surface
- Old, weathered asbestos sheets may show fibre patterns on broken edges
- Any powdery or crumbling surface is a warning sign and should not be disturbed
If multiple clues line up, it is safer to assume you are dealing with asbestos and arrange professional advice. Remember that other materials, such as non asbestos fibre cement and plasterboard, can look similar, which is why testing is the only way to confirm.
Why Is Visual Identification Of Asbestos Simply Not Enough?
Even if you understand all the visual characteristics, you cannot confirm how to identify asbestos sheeting with your eyes alone. Australian regulators are very clear that visual identification is only a screening tool and that any decision that a material contains asbestos should be backed by laboratory testing unless there is strong documentary evidence.
Reasons visual identification has limits:
- Some asbestos free materials look almost identical to older asbestos cement sheet products
- Asbestos fibres are microscopic and cannot be seen on the surface
- Many surfaces have been painted, skim coated, or tiled over, hiding their original appearance
- Only trained professionals can safely take samples for testing without creating unnecessary exposure
To comply with Australian building and standard regulations, duty holders in workplaces must keep an asbestos register, identify asbestos containing materials through inspection and testing where required, and manage any health risks according to the relevant code of practice. Homeowners are not legally required to keep a register, but the same principles of safe handling, testing, and asbestos removal by licensed operators still apply if they want to deal with asbestos safely.
How Do Australian Laws And Standards Manage Asbestos In Buildings?
In Australia, asbestos is recognised as a prohibited, dangerous substance, and there are strict legal duties around asbestos containing materials in workplaces and, in many situations, in residential and commercial buildings that are used as workplaces or shared spaces.
Key points include:
- Asbestos and asbestos containing materials are banned from new use
- Work health and safety laws require PCBUs (persons conducting a business or undertaking) to identify asbestos containing products in workplaces and record them in an asbestos register
- Codes of practice, such as the national model code on how to manage and control asbestos in the workplace, set out how to identify, label, manage and arrange removal of asbestos materials to reduce health risks from exposure
- When asbestos removal is necessary, it must usually be carried out by licensed asbestos removalists using strict controls, especially where friable asbestos or large areas are involved
For homeowners, the rules vary slightly by state or territory, but the overall message is the same. Asbestos materials should be left undisturbed where they are in good condition, and any work that might disturb asbestos, including removal before roofing upgrades, should follow the same safety principles that apply in commercial buildings.
What Should You Do If You Suspect Asbestos In Your Roofing Or Walls?
If you suspect asbestos is present in your roofing, external cladding, ceilings, insulation or walls, the safest steps are cautious and conservative.
Here is a practical approach that fits with Australian guidance and keeps health front and centre:
- Treat the suspect material as asbestos containing until proven otherwise
- Avoid drilling, cutting, sanding or breaking the sheets
- Keep children and vulnerable people away from suspect asbestos materials
- Do not pressure wash old asbestos cement roofs or external cladding
- Contact your state or territory asbestos information service or a licensed asbestos assessor for advice and testing
- If asbestos removal is needed, use licensed asbestos removalists who follow the applicable codes of practice
If testing confirms that the material contains asbestos, you can then plan the next steps. For many homeowners, the best long term solution is to replace ageing asbestos roofing with safer modern roofing and to update gutters and downpipes at the same time.
When you are ready to move towards asbestos free roofing, the team at fortified.com.au can help you coordinate safe roof works alongside licensed asbestos specialists. For example, if testing confirms your roof sheets are asbestos containing products, you may choose to:
- Organise a safe, staged roof replacement in Brisbane that swaps asbestos cement roofing for modern metal roofing
- Plan re-roofing services that combine asbestos removal by licensed contractors with new steel roofing installed to current standards
- Upgrade to Colorbond roofing in Brisbane or a Zincalume roof replacement for durable, asbestos free roofing with improved properties and better long term performance
In every case, the key is to respect the health risks and legal requirements, and to let trained professionals handle asbestos so you are not unnecessarily exposed.
How Can Modern Roofing And Guttering Options Help You Move To Asbestos Free Materials?
Once suspect asbestos sheets have been safely removed by licensed contractors, you can take the opportunity to improve more than just the look of your roof. Modern metal roofing, insulation and guttering can greatly improve the fire resistance, heat resistance, insulation and drainage performance of your home or commercial buildings.
With fortified.com.au you can:
- Install new roof insulation with roof insulation in Brisbane to improve comfort and energy efficiency once the old asbestos materials are gone
- Improve ventilation and indoor comfort with roof ventilators in Brisbane after asbestos roofing has been replaced
- Fix leaks and damage that may have developed around older asbestos sheets using metal roof repairs once the roof is confirmed asbestos free
- Update drainage with commercial guttering for larger buildings and gutter replacement in Brisbane for homes and smaller commercial buildings
- Address ageing downpipes by arranging downpipe replacement in Brisbane as part of your overall roof upgrade
- Protect new gutters from leaf litter with gutter guard solutions and tidy up roof edges with fascia capping in Brisbane
By pairing safe asbestos removal with smart upgrades, you are not only managing hazardous materials correctly but also improving the long term properties of your building. You end up with insulation, roofing and drainage that are safer, easier to maintain and fully compliant with modern standards.
How Can You Reduce Health Risks From Asbestos Exposure During Renovations?
Many cases of asbestos exposure happen during renovations when people accidentally disturb asbestos containing materials in older homes. Recent Australian data show that home renovations are a common source of non occupational asbestos exposure, especially in many older buildings built before 1990.
To reduce risk:
- Assume that older ceilings, walls, floor coverings and external cladding in older properties may contain asbestos, especially if they are cement based sheets
- Use visual identification only as a screening step, not as proof that a material is asbestos free
- Plan any major work around asbestos testing and, if necessary, professional asbestos removal
- Keep areas containing suspect material left undisturbed until experts confirm whether they contain asbestos
- If you discover broken, crumbling or damaged cement sheet around sheds, eaves or roofing, avoid touching it and seek expert advice straight away
If you are planning roofing or guttering construction work that might disturb asbestos cement sheeting or other asbestos materials, it is safer to coordinate the asbestos removal and roof works as one project. That way the area is controlled, exposure is minimised and you can move directly to new asbestos free roofing with help from fortified.com.au.
What Are The Key Takeaways For Australians Who Want To Identify Asbestos Safely?
So, how do you bring all this information together and actually identify asbestos in a safe, practical way?
Here are the main points to remember:
- In many older buildings, especially those constructed or renovated prior to the 1990s, asbestos containing materials may still be present in roofs, walls, ceilings and other building materials
- Asbestos cement sheeting, corrugated asbestos cement sheets, flat sheets and some floor coverings are common locations, along with insulation and external cladding on sheds and garages
- Visual characteristics such as colour, thickness, hardness and even a golf ball type dimpled pattern can suggest asbestos, but visual identification is never enough to confirm that a material contains asbestos
- Asbestos fibres are tiny fibres that pose serious health risks if you are exposed, including mesothelioma and lung cancer, so safe handling and strict control are essential
- Australian laws require that asbestos containing products in workplaces are identified and managed, and the safest approach for homeowners is to follow similar standards, using testing and licensed asbestos removal where needed
