Roof Flashing FAQs
What is a flashing on a roof?
Roof flashing is a folded metal strip installed to seal joints and direct water away from roof openings, valleys and wall junctions. In Australia, flashings are most often made from COLORBOND® or ZINCALUME® steel for long-term corrosion resistance.
Is flashing on the roof necessary?
Yes - flashings are essential to prevent leaks and water damage. They create a weatherproof barrier wherever roof sheets meet walls, chimneys or other structures, ensuring the building remains watertight even during heavy rain.
What are the standards for flashing in Australia?
All flashings and cappings should comply with AS/NZS 1397 (steel sheet and strip) and AS/NZS 2728 (pre-painted and organic-coated steel). .55 BMT BlueScope steel flashing meets these standards.
Is it expensive to replace roof flashing?
Replacing flashing is generally affordable when done early. Costs depend on the profile and material, but COLORBOND® steel flashings offer the best value because they last decades with minimal maintenance and match your existing roof colour.
