To prevent leaks

The main purpose of flashing on a roof is to prevent leaks. Flashing is a material, often made of metal, installed at critical points of a roof where different sections meet or where there is a projection through the roofing material, such as chimneys or skylights. Its primary function is to direct water away from these vulnerable areas, ensuring that water does not penetrate the underlying roofing structure and cause damage. Properly installed flashing effectively channels water off the roof surface, significantly reducing the risk of leaks and moisture intrusion into the building. By protecting these areas, flashing plays a crucial role in maintaining the overall integrity and longevity of the roofing system.
