Why Roof Flashing Fails
Flashing is one of the most common points of failure in Brisbane roofs. Common causes of flashing damage include:
- Rust and corrosion from years of exposure
- Incorrect installation or poor-quality materials
- Movement in the roof structure causing cracks and gaps
- Wear and tear around chimneys, skylights, and vents
- Heavy storms or fallen debris damaging roof joints

Frequently Asked Questions
- What is roof flashing and why is it important?
Roof flashing is a protective material used to seal joints and vulnerable areas of your roof, preventing water from seeping inside.
- How do I know if I need a roof flashing repair?
Signs include ceiling stains, leaks during heavy rain, dampness around chimneys or skylights, or visible rust and cracks in your flashing.
- Can roof flashing be repaired, or does it need full replacement?
Minor issues can be resealed or patched, but heavily corroded or damaged flashing often requires replacement for a lasting fix.
- Do you work on both tile and metal roofs?
Yes. We repair and install flashing on all roof types, including tiled and Colorbond metal roofs.
