Short Answer:
In Australia, insurers may declare a roof uninsurable if it has:
✔️ Severe structural damage (sagging, major cracks)
✔️ Older than 25-30 years (depends on material)
✔️ Non-compliant repairs (DIY fixes or unlicensed work)
✔️ High-risk materials (asbestos, untreated timber)
✔️ Repeated claim history (3+ claims in 5 years)
(Example: A 35-year-old corrugated iron roof in Brisbane with rust perforations would likely be denied.)
Why Australian Insurers Refuse Roof Coverage
Australia’s extreme weather (cyclones, hail, bushfires) makes insurers hyper-selective. Beyond age and damage, these factors trigger rejections:
1. Material Risks
- Concrete Tile: Cracks from thermal expansion → water ingress
- Terracotta: Brittle in hail → requires special endorsements
- Colorbond: Poor installation → wind uplift failures
Data Point: 68% of denied claims in QLD involve roofs over 20 years old (Suncorp 2023 data).
2. Location-Specific Issues
- BAL 40+ Bushfire Zones: Requires ember-proof materials
- Cyclone-Prone Regions: Must meet AS/NZS 1562.3 wind ratings
- Coastal Areas: Salt corrosion voids warranties
3. Documentation Gaps
- Missing certification for modifications
- No evidence of annual inspections
- Unpermitted roof-mounted solar installations
