A professional report provides valuable negotiating information before settlement.
What Is Included in a Roof Inspection?
Although every contractor follows slightly different procedures, comprehensive inspections generally evaluate the following components.
Roof Covering
Inspectors assess:
- Steel roofing
- COLORBOND® roofing
- Colorsteel® roofing
- Concrete tiles
- Terracotta tiles
- Membrane roofing
Signs of ageing, corrosion, and damage are carefully documented.
Roof Structure
Structural assessments include:
- Rafters
- Battens
- Purlins
- Trusses
- Roof framing
- Roof movement
Structural deterioration often develops long before visible roof leaks appear.
Flashing
Roof flashing protects vulnerable roof junctions.
Inspectors evaluate flashing around:
- Chimneys
- Skylights
- Roof valleys
- Solar panels
- Roof penetrations
Failed flashing remains one of the leading causes of roof leaks.
Gutters and Drainage
Roof drainage systems are inspected for:
