What Is Ridge Capping?
Ridge capping, also known as roof ridge flashing, is the flashing that covers the peak where two roof sheets meet. It seals the highest point of your roof to stop rain, dust, and debris from entering beneath the sheeting. Using COLORBOND® ridge capping ensures a watertight, clean finish that complements the look of your entire roofline.
Designed for both new builds and re-roofing projects, ridge capping is essential for preventing leaks and protecting structural timber from moisture damage. It also adds a polished, professional edge to your home or commercial building.
