Proper flashing at roof-to-wall intersections is absolutely vital for preventing water damage and ensuring the long-term integrity of a roofing system. SEMCO Aluminum Step Flashing provides roofing contractors with a high-quality, dependable solution for these critical areas. Manufactured by SEMCO, this step flashing is made from durable, corrosion-resistant aluminum, ensuring it will withstand the elements and provide lasting protection against moisture intrusion.
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 an 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 Aluminum Step Flashing is an essential component for both new construction and reroofing projects. Its lightweight nature and inherent flexibility make aluminum step flashing easy to cut, bend, and install, allowing contractors to efficiently create a secure, watertight seal. Available in standard sizes and typically sold in bundles, SEMCO Aluminum Step Flashing provides a cost-effective and reliable method for flashing roof-to-wall details. By choosing SEMCO Aluminum Step Flashing from A1A Wholesale Supply, contractors can ensure they are using a quality product that provides essential protection against leaks and contributes to a durable, weather-resistant roof.
