What is Roof Flashing?
Roof flashing can be likened to the unsung hero of a home’s roofing system. Typically made of thin metal, such as galvanised steel, aluminium, or copper, flashing serves as a protective barrier. Its primary role is to direct water away from critical areas of the roof, ensuring that water doesn’t seep into your home. Designed to bridge the gap between roofing materials and roof projections, flashing can be observed as thin pieces of metal that seal the spaces where different building components come together.
These might be areas where the chimney intersects with the roof or around vents, windows, and skylights. Given its metallic nature, flashing is usually shiny when new but can tarnish or patina over time, especially if made of copper. It serves as a watertight bridge, seamlessly integrating with the rest of the roof to ensure that every nook and cranny is guarded against potential water intrusion.
