Step Flashing, also known as Step Flash or Step Flashing Kit, is used to provide weatherproofing and protection against water intrusion at the junction between a roof and a vertical wall or chimney. Its features include a durable material, such as galvanized steel or aluminum, with a stepped design that fits securely over the roof shingles and under the siding or masonry. The benefits of Step Flashing include improved waterproofing, reduced risk of leaks and water damage, and enhanced durability and longevity of the roofing system.
