Why Asbestos Roofs Are a Risk?
Asbestos roofing was widely installed in Australia until the 1980s. While durable, it contains fibres that, if disturbed, can cause serious health issues such as mesothelioma condition and lung cancer. The Australian Government’s Asbestos Safety and Eradication Agency warns that no level of exposure is considered safe. If your roof contains asbestos, removal is the most effective way to reduce long-term risks and maintain property value.
Process of Asbestos Roof Removal
1. Initial Assessment and Planning
The first step in the removal process is conducting a thorough assessment of the roof’s condition. A licensed asbestos removalist will inspect the asbestos in roofing materials. This might include testing samples from your roof in a lab, as asbestos can often be hidden in materials like cement sheeting or insulation.
During the assessment, the removalist will:
- Determine the Extent of Contamination: Is it just the roof, or are other parts of the structure also affected?
- Evaluate the Structural Integrity: This will help decide the safest removal method.
- Develop a Detailed Removal Plan: This plan will outline the necessary safety precautions, tools, and disposal strategies.
Once the assessment is complete, the team will provide you with a quote and discuss the safest removal procedure.
2. Obtaining Necessary Permits
Asbestos removal in Australia is regulated by state and federal laws, and before starting any work, the removalist must ensure that they have obtained the necessary permits and approvals. This includes informing local authorities about the planned removal.
If the removal is large-scale or involves a public place, additional environmental considerations may need to be addressed. The licensed contractor is responsible for complying with regulations such as:
- Work Health and Safety (WHS) Regulations: Work health and safety (WHS) regulations ensure the safety of workers and the general public.
- Environmental Management Guidelines: These rules cover the proper disposal of asbestos and the prevention of contamination.
Failure to comply with these regulations can result in heavy fines or legal consequences, making it critical to hire a qualified asbestos removal specialist.
3. Setting Up the Work Area
Asbestos removal can release harmful fibres into the air, which is why it’s essential to seal off the work area. The removalists will set up the area with appropriate containment barriers to keep the dust and debris from spreading to other parts of the property.
They will:
- Cover the ground with plastic sheeting to catch any debris or asbestos that may fall during the removal process.
- Set up negative air pressure. This ensures that air from the work area is being sucked out through high-efficiency air filters, preventing asbestos fibres from escaping.
- Mark the site to restrict access to authorised personnel only.
The workers will also wear personal protective equipment (PPE), including disposable coveralls, respirators, and gloves, to minimise their asbestos exposure.
4. Asbestos Roof Removal
With the area properly sealed and safety measures in place, the actual process of removing the asbestos roof can begin. The removal team will work methodically, taking care to avoid disturbing the asbestos fibres as much as possible.
Here’s how it generally unfolds:
Removing roof sheets: If your roof is made of asbestos-cement sheets, the removalist will use special tools to carefully detach the sheets, ensuring that they are not cracked or broken. Cracking asbestos sheets can release fibres into the air.
- Careful Handling: The sheets will be carefully lowered to the ground using ropes or hoists, preventing any unnecessary impact or disruption.
- Wet Methods: In some cases, asbestos sheets may be lightly sprayed with water or a wetting agent to reduce dust during the removal process.
- Avoiding Power Tools: To prevent the release of fibres, power tools like drills or saws are avoided. Only hand tools are used for the job.
Throughout this phase, the workers remain vigilant about minimising airborne asbestos fibres, as even a small amount of exposure can be dangerous.
5. Cleaning and Decontamination
After all the asbestos roofing material has been removed, the site needs to be thoroughly cleaned and decontaminated to ensure no fibres remain. This step is crucial to guarantee that the area is safe for future use.
The removal team will:
- Double-Bag All Asbestos Waste: The asbestos sheeting and any waste materials will be carefully placed in heavy-duty plastic bags labelled as hazardous waste.
- Use Industrial-Grade Vacuums: The team will vacuum the area using filters to ensure that even the smallest asbestos fibres are removed from surfaces.
- Inspect the Area: Once cleaned, the work site will be rechecked for any remaining traces of asbestos.
Once the area passes inspection, the team can move on to the final phase of the process.
6. Disposal of Asbestos Waste
Asbestos removal waste must be disposed of in a licensed asbestos disposal facility. The asbestos removal team will transport the waste in a secure and sealed manner to ensure that the material doesn’t pose a risk to the public during transit.
The disposal facility will:
- Safely Bury the Asbestos Waste: The waste is buried in a designated area that is specifically engineered to contain the hazardous material and prevent it from leaching into the environment.
- Document Everything: The removalist will provide you with a certificate of disposal to confirm that the asbestos was disposed of correctly and in compliance with local regulations.
7. Final Inspection and Clearance
Once the roof is removed and the area cleaned, a final inspection is conducted. This may involve independent air monitoring to ensure that the environment is free of asbestos fibres. Only when the site has been deemed completely safe can you begin with reconstruction or re-roofing.
