Proper flashing at the intersections of roof slopes and vertical walls is absolutely critical for preventing water damage and ensuring the long-term performance of any roofing system. SEMCO Galvanized Steel Step Flashing offers roofing contractors a robust, reliable, and economical solution for these vital areas. Manufactured by SEMCO, this step flashing is constructed from durable galvanized steel. The galvanization process applies a protective zinc coating to the steel, enhancing its resistance to corrosion and contributing to its longevity in exterior applications.
Step flashing is specifically designed for use where a roof slope meets a vertical surface, such as sidewalls, chimneys, dormers, and other similar transitions. It is installed in a critical overlapping, stair-step pattern with each course of shingles. Each piece is typically bent at a 90-degree angle, with one leg lying flat on the roof deck (under the shingle above) and the other leg extending up the vertical wall. This layered installation method creates a shingle-like effect with the flashing, effectively diverting water away from the intersection and preventing it from seeping into the building structure.
SEMCO Galvanized Steel Step Flashing is an essential component for both new construction and reroofing projects. Galvanized steel provides inherent strength and durability, making it resistant to bending or deformation during installation and throughout its service life. It is a cost-effective material option while still providing the necessary protection against water intrusion. Available in standard gauges and sizes and typically sold in bundles, SEMCO Galvanized Steel Step Flashing provides a dependable and economical method for flashing roof-to-wall details. By choosing SEMCO Galvanized Steel Step Flashing from A1A Wholesale Supply, contractors can ensure they are using a quality product that provides essential protection and contributes to a sound and weather-resistant roof.
