The AMERIMAX 70800 is a galvanized steel step flashing piece measuring 5 x 7 inches, designed to create watertight seals at roof-to-wall intersections and roof penetrations. Galvanized construction resists rust and corrosion, extending service life in exposed exterior applications. Roofers and general contractors use this flashing during new construction and re-roofing projects where a reliable, code-compliant moisture barrier is required at critical transition points. Each piece is sold individually and the minimum order quantity is 100 units, making it a practical stocking item for roofing contractors.
This step flashing is suited for residential and light commercial roofing applications. It installs around chimneys, skylights, and dormers to prevent water infiltration at roof penetrations and wall intersections. The galvanized finish makes it appropriate for outdoor exposure where raw steel would be vulnerable to moisture. Beyond roofing, the material is also used in hobby, craft, and general household fabrication projects that require a formable, corrosion-resistant sheet metal piece.
Designed as an OEM-style replacement and standard fitment step flashing for residential and light commercial sloped roofing systems at wall intersections and penetrations including chimneys, skylights, and dormers.
Step flashing is installed by qualified roofers and general contractors following local building codes and manufacturer roofing system requirements. Power down any electrical components near the work area and follow all fall-protection regulations before beginning roof work. Each flashing piece is typically interlaced with shingle courses and fastened to the vertical wall or curb surface. Do not substitute step flashing for continuous flashing where code or manufacturer guidelines require a different flashing type.
