Galvanized roll flashing is a flexible, corrosion-resistant metal sheet designed to provide a weatherproof barrier in various construction applications. Made from steel coated with a protective layer of zinc, it offers excellent durability and resistance to rust and moisture. This versatile flashing is commonly used for sealing roof valleys, chimney bases, wall intersections, and other vulnerable areas where water infiltration could occur. Its roll format allows for easy cutting and shaping to fit specific project needs, making it an essential material for both residential and commercial construction.
