How to Identify Asbestos in Commercial Roofs

Asbestos roofing remains a hidden hazard in many NSW commercial and industrial buildings. This guide explains how to identify asbestos materials, understand friable vs non-friable types, follow safe testing steps, and engage a licensed asbestos assessor to ensure compliance and workplace safety.

Asbestos Roof Identification: Why It Matters for NSW Businesses

For decades, asbestos was considered a miracle building material—strong, fire-resistant, and durable. It was widely used across Australia until the late 1980s, especially in commercial and industrial roofing. However, its legacy continues to pose a serious health and legal risk.

If your property was built or renovated before 1990, there’s a strong chance asbestos-containing materials (ACMs) are still present in the roof sheeting, flashings, or insulation layers. Identifying asbestos early is critical to prevent costly contamination, protect your workers, and ensure compliance with SafeWork NSW regulations.

At Element Metal Roofing, we regularly help NSW businesses safely assess, remove, and replace asbestos roofs—minimising disruption while maintaining full legal and environmental compliance.

Asbestos Testing in Australia: Understanding the Process

Accurately identifying asbestos cannot be done by sight alone. Many asbestos-containing materials resemble modern fibre cement sheets, and incorrect handling can release dangerous fibres into the air.

1. Initial Roof Inspection

A visual inspection can identify likely areas of concern. Look for:

• Old corrugated sheeting, often marked with manufacturer codes such as “Super Six”
  
  
• Weathered or brittle panels with visible deterioration
  
  
• Sealants, gaskets, or roof linings installed pre-1990
  
  

However, no roof should be disturbed or sampled without professional guidance. Asbestos dust and fibres are invisible and can spread quickly through HVAC systems and ceiling spaces.

2. Sample Collection by a Licensed Assessor

Under NSW regulations, only a licensed asbestos assessor should collect samples for testing. They will:

• Wear approved PPE and use controlled sampling tools
  
  
• Dampen surfaces to prevent fibre release
  
  
• Collect a small section of material for laboratory analysis
  
  
• Seal and label the sample for secure transport
  
  

Attempting DIY asbestos testing is not only unsafe—it breaches Work Health and Safety (WHS) regulations and may invalidate insurance coverage.

3. NATA-Accredited Laboratory Testing

Samples are analysed under microscopy to confirm asbestos type (chrysotile, amosite, or crocidolite) and concentration. The results guide the next steps—whether management, encapsulation, or full removal and replacement are required.

Friable vs Non-Friable: What’s the Difference?

Understanding whether asbestos is friable or non-friable is essential for risk assessment and compliance planning.

Friable Asbestos

• Can be easily crumbled or reduced to powder when dry
  
  
• Common in insulation, lagging, and sprayed coatings
  
  
• Releases fibres readily into the air
  
  
• Requires Class A asbestos removal licence and strict containment procedures
  
  

Non-Friable Asbestos

• Firmly bound in a solid matrix, such as cement sheeting or vinyl tiles
  
  
• Lower risk when intact but can become friable through damage, drilling, or weathering
  
  
• Managed or removed by a Class B licensed asbestos removalist
  
  

Most asbestos roofing materials used in NSW fall under the non-friable category. However, decades of exposure to sunlight, rain, and corrosion can cause them to deteriorate—turning once-stable sheets into friable, high-risk materials.

Licensed Asbestos Assessor Guidance: Ensuring Legal Compliance

Under NSW’s Work Health and Safety Regulation 2017, duty holders—including property owners, landlords, and business operators—must ensure asbestos risks are identified and managed by competent professionals.

A Licensed Asbestos Assessor (LAA) plays a central role in compliance. They:

• Conduct asbestos surveys and risk assessments
  
  
• Issue clearance certificates following removal work
  
  
• Maintain documentation for SafeWork NSW and environmental reporting
  
  
• Advise on replacement materials and re-roofing options
  
  

Working with an experienced assessor ensures you meet all obligations under the NSW Asbestos Remediation Framework, avoiding fines, delays, or exposure incidents.

When to Arrange an Asbestos Roof Inspection

You should engage a licensed asbestos professional if:

• Your building was constructed before 1990
  
  
• Roof sheeting appears old, brittle, or damaged
  
  
• You plan renovations, solar panel installation, or HVAC upgrades
  
  
• You’ve discovered broken or weathered panels during maintenance
  
  

Regular asbestos audits are also recommended every five years for commercial and industrial facilities, or sooner if the roof condition changes. And for buyers, these audits are critical to uncovering hidden risks before committing to a property.

Safe Testing Steps: A Summary for Business Owners

Here’s a compliant step-by-step process to follow:

• Do not disturb suspect materials – Stop any work immediately.
  
  
• Engage a licensed asbestos assessor – Only professionals can collect samples safely.
  
  
• Laboratory testing – Use NATA-accredited labs for confirmation.
  
  
• Risk management plan – Develop a compliant asbestos register and control plan.
  
  
• Removal or encapsulation – Conducted by licensed asbestos removalists under controlled conditions.
  
  
• Final clearance – A licensed assessor issues certification confirming the site is safe.
  
  

Following these steps not only ensures worker safety but protects your business from regulatory and insurance complications.
