- • Inspect for pest activity
- • Note any temperature changes
- • Thermal imaging inspection
- • R-value performance testing
- • Comprehensive condition report
- • Upgrade recommendations
- • Storm or leak damage
- • Pest infestation cleanup
- • Major renovation work
- • Performance issues
Seasonal Checklist
Autumn/Winter:
- • Pre-winter performance check
- • Identify cold spots
- • Check for condensation issues
- • Monitor heating bill changes
Spring/Summer:
- • Post-winter damage assessment
- • Ventilation system check
- • Pest prevention measures
- • Plan any upgrade work
Warning Signs That Need Attention
Immediate Action Required
- Wet or soggy insulation - Replace immediately to prevent mould
- Mould or strong odours - Health hazard requiring professional removal
- Heavy pest contamination - Sanitization and replacement needed
- Asbestos-containing materials - Professional assessment required
Monitor and Plan
- Compressed insulation - Lost R-value, top-up may help
- Gaps or bare patches - Reduced effectiveness, needs attention
- Increased heating bills - Performance degradation likely
- Age over 20-30 years - Consider upgrading to modern materials
Safety Warning
Always wear appropriate PPE when inspecting roof spaces: dust mask, gloves, long sleeves, and torch. Be cautious of electrical wiring and use proper footing. If you suspect asbestos, do not disturb the material and contact professionals immediately.
DIY Maintenance Tasks
Safe DIY Tasks
- Visual inspections - Check condition without disturbing insulation
- Minor gap filling - Add small amounts of bulk insulation to gaps
- Ventilation maintenance - Clear blocked roof vents
- Moisture prevention - Ensure bathroom/kitchen fans work properly
Leave to Professionals
- Wet insulation removal - Health hazards and proper disposal
- Pest-contaminated material - Sanitization requirements
- Major replacements - Proper installation critical
- Electrical work around wiring - Licensed electrician required
Step-by-Step Inspection Guide
Preparation
Gather torch, dust mask, gloves, camera, and measuring tape. Choose a dry day for inspection.
Access and Safety
Use proper ladder safety. Check footing in roof space and identify all electrical hazards.
Documentation
Take photos of overall coverage, note gaps, measure thickness, and record any issues.
Assessment
Compare current condition to installation specifications and note performance changes.
Pest Prevention and Management
Prevention
- • Seal entry points around eaves
- • Install pest-proof vents
- • Remove tree branches touching roof
- • Regular exterior maintenance
- • Monitor for early signs
Detection
- • Droppings in insulation
- • Scratching sounds at night
- • Tracks or pathways in insulation
- • Nesting materials visible
- • Strong urine odours
Response
- • Professional pest control
- • Contaminated insulation removal
- • Sanitization of roof space
- • Replace affected insulation
- • Seal entry points permanently
Health Warning
Rodent-contaminated insulation poses serious health risks including respiratory illness and disease transmission.
Never attempt to clean heavily contaminated insulation yourself. Professional removal and sanitization is essential for health and safety.

Maintenance FAQ
Should I replace old insulation that still looks okay?
Insulation over 20-30 years old may have reduced R-value even if it looks fine. Modern materials offer better performance and longevity. Consider professional thermal assessment to determine if upgrade is worthwhile.
Can I add new insulation over old insulation?
Yes, if the existing insulation is dry and in good condition. This can be cost-effective for improving R-values. However, wet, mouldy, or pest-contaminated insulation must be removed first.
How do I know if my insulation has lost effectiveness?
Signs include higher heating bills, cold spots on ceilings, condensation issues, and visible compression or displacement. Professional thermal imaging can definitively assess performance loss.
Is professional maintenance worth the cost?
Professional inspections every 5-10 years can identify issues early, preventing costly problems and ensuring optimal performance. The cost is typically $300-500 versus thousands for major repairs or replacement.
