Why Proper Roof Flashing Installation Matters
Incorrectly installed or poor-quality flashing is one of the leading causes of roof leaks in Brisbane properties. Flashing protects against:
- Water leaks during heavy rain
- Structural damage from long-term moisture ingress
- Mould, mildew, and dampness inside ceilings and walls
- Costly interior repairs due to water staining and rot
