Amerimax Home Products 70420 Galvanized Roll Flashing

Product Description

The AMERIMAX HOME PRODUCTS 70420 is a galvanized steel roll flashing used to seal and weatherproof transitions between roofing, siding, windows, doors, and other building envelope penetrations. Measuring 20 inches wide by 10 feet long with a 0.010-inch gauge thickness, this roll delivers enough coverage for standard residential flashing applications in a single piece. The galvanized finish provides corrosion resistance suited to exterior exposure. Roofing contractors, siding installers, and general building tradespeople are the typical installers for this product type.

This roll flashing is suited for residential and light commercial construction and repair work. Common applications include step flashing at roof-to-wall intersections, kick-out flashing, window and door head flashing, and valley flashing as a base layer. At 20 inches wide, the roll can be cut and bent on-site to fit a range of profile geometries using standard sheet metal tools. The 10-foot length is practical for single-opening applications or for cutting multiple shorter pieces from one roll.

Installation Notes

Flashing installation is typically performed by licensed roofing or siding contractors and should conform to local building codes and manufacturer roofing system requirements. Cut and bend the roll using aviation snips and a brake or bending bar before fastening. Always overlap flashing sections in the direction of water flow and seal exposed edges per applicable code. Wear cut-resistant gloves when handling cut sheet metal edges.
