Roofing work is among the most hazardous activities in the Australian construction industry. Falls from roofs remain the leading cause of workplace fatalities and serious injuries across the country. In 2024 alone, multiple incidents highlighted the critical need for stringent safety measures. For instance, a 71-year-old tradesman tragically lost his life after falling approximately five meters through a rusted tin roof in Perth.
Whether you’re a homeowner planning a roof repair, a builder overseeing a construction project, or a tradesperson working at height, understanding and implementing proper roof safety protocols is paramount. This guide delves into the essential aspects of roof safety in Australia, emphasizing compliance with Work Health and Safety (WHS) regulations, best practices, and real-world lessons.

⚠️ Why Roof Safety Matters
According to SafeWork Australia, falls from heights account for a significant proportion of workplace fatalities. Roofing tasks—such as repairs, installations, and maintenance—often involve working at elevated levels, increasing the risk of falls. Additionally, fragile roofing materials like skylights, polycarbonate sheeting, and rusted metal can unexpectedly give way under weight, leading to severe injuries or fatalities.
📋 Legal Framework: WHS Regulations and Codes of Practice
Australia’s WHS laws mandate that employers and self-employed individuals ensure, so far as is reasonably practicable, the health and safety of workers while they are at work. This includes providing and maintaining a work environment without risks to health and safety. Specifically, the WHS Regulation 2011 outlines requirements for managing risks associated with working at heights, including:
- Risk Assessment: Identifying hazards that may cause falls and assessing the risks associated with those hazards.
- Control Measures: Implementing control measures to eliminate or minimize risks, such as installing edge protection or using fall arrest systems.
- Training and Supervision: Ensuring workers are adequately trained and supervised when working at heights.
The “Managing the Risk of Falls at Workplaces Code of Practice” provides practical guidance on complying with these regulations, emphasizing the importance of eliminating or minimizing risks associated with working at heights.
🛠️ Best Practices for Roof Safety
1. Implement Edge Protection
Installing physical edge protection, such as guardrails or scaffolding, is one of the most effective ways to prevent falls from roofs. According to SafeWork NSW, guardrail systems should include top, mid, and bottom rails or toe-boards, with gaps not exceeding 450 mm. The top rail should be at least 900 mm above the working surface, and infill panels should be used where the pitch of the roof exceeds 26 degrees.
2. Use Safety Mesh for Fragile Roofs
For roofs made of fragile materials like polycarbonate or plastic sheeting, safety mesh can prevent workers from falling through the roof. The “Managing the Risk of Falls at Workplaces Code of Practice” specifies that safety mesh should comply with AS/NZS 4389 and be securely fixed to the structure.
3. Conduct Thorough Risk Assessments
Before commencing any roofing work, conduct a detailed risk assessment to identify potential hazards, including:
- Fragile Roof Surfaces: Identify areas that may not support the weight of a worker.
- Weather Conditions: Assess the impact of wind, rain, or heat on safety.
- Tools and Equipment: Ensure all tools are in good condition and appropriate for the task.
Implement control measures to mitigate identified risks, such as using appropriate personal protective equipment (PPE) and ensuring safe access to the roof.
4. Provide Adequate Training and Supervision
Ensure all workers involved in roofing tasks are adequately trained in the use of safety equipment, hazard identification, and emergency procedures. Supervision should be provided to ensure adherence to safety protocols and to address any issues promptly .
5. Maintain and Inspect Equipment Regularly
Regularly inspect and maintain safety equipment, including harnesses, lanyards, and anchor points, to ensure they are in good working condition. Replace any damaged or worn equipment immediately to maintain safety standards.
⚖️ Real-World Lessons: Recent Incidents
Recent incidents underscore the importance of adhering to roof safety protocols:
- Skylight Fall in South Australia: A worker fell 4.6 meters through a skylight at an aged care facility in Bellevue Heights, resulting in serious injuries. Investigations revealed that the risk assessment failed to identify the skylight as a hazard, leading to fines for the responsible companies.
- Geelong Roof Fall: A worker fell nearly 4 meters from a roof in Geelong, suffering a fractured pelvis and bleeding on the brain. The company was fined $40,000 for failing to provide necessary fall protection measures.
These incidents highlight the critical need for comprehensive risk assessments, proper training, and the implementation of effective control measures to prevent falls and ensure worker safety.
🧰 Roof Safety Checklist for Homeowners
If you’re a homeowner planning roofing work, consider the following checklist:
- Hire Qualified Professionals: Ensure that contractors are licensed and experienced in roof safety and work practices.
- Verify Safety Measures: Confirm that appropriate edge protection and safety systems are in place.
