Amerimax Home Products 66320 Aluminum Flashing Roll

Product Description

The AMERIMAX HOME PRODUCTS 66320 is a roll of aluminum flashing designed for weatherproofing and moisture management in residential and light commercial construction. Measuring 20 inches wide by 10 feet long with a thickness of 0.0078 inches, this flashing provides a durable, corrosion-resistant barrier at roof edges, window and door openings, chimneys, and transitions where water infiltration is a concern. Aluminum construction keeps the roll lightweight at 1.8 pounds while delivering reliable performance in exterior applications. Roofers, siding contractors, and general contractors install this type of flashing as part of standard building envelope work.

This flashing roll is suited for residential roofing, siding, and masonry applications where a flexible, formable metal barrier is required. Common uses include step flashing, counter flashing, valley flashing, and window sill pan flashing. The 20-inch width accommodates a range of standard flashing details without requiring additional trimming on most installations. It ships as a single roll.

Installation Notes

Aluminum flashing is typically installed by roofing or siding contractors following local building code requirements and manufacturer guidelines. Cut and form the flashing using aviation snips and a hand seamer or bending brake. Avoid contact between aluminum flashing and dissimilar metals such as copper or steel without an appropriate isolating membrane, as galvanic corrosion can occur over time. Secure flashing with compatible fasteners and seal edges with an appropriate roofing sealant as required by the application.
