Amerimax Home Products 70418 Galvanized Roll Flashing

Product Description

The AMERIMAX HOME PRODUCTS 70418 is a galvanized roll flashing measuring 18 inches wide by 10 feet long with a material thickness of 0.010 inches. It is used to seal and weatherproof transitions at roof edges, wall penetrations, chimneys, skylights, and other exterior junctions where water infiltration is a concern. The galvanized steel construction provides corrosion resistance suitable for outdoor exposure. This roll format allows the installer to cut custom lengths on site, reducing waste and fitting irregular or non-standard openings. It is handled by roofers, sheet metal workers, and general contractors during new construction and repair work.

This flashing is suited for residential and light commercial roofing and exterior wall applications. It is commonly used at roof-to-wall transitions, around chimney bases, along rake and eave edges, and at dormer intersections. The 18-inch width accommodates a variety of overlap and coverage requirements without requiring multiple layers in standard applications. Installers working on re-roofing projects will find the roll format convenient for staging material at the work site before cutting to fit.

Key Features

• 18-inch width provides generous coverage for roof-to-wall and penetration flashing details
• 10-foot roll length allows on-site cutting to required dimensions
• 0.010-inch gauge galvanized steel resists corrosion in exterior weather exposure
• Roll format reduces handling complexity compared to pre-cut flat stock
• Galvanized finish accepts common roofing sealants and lap cement

Compatibility

Designed as a general-purpose galvanized roll flashing for use in standard residential and light commercial roofing and exterior construction applications where an 18-inch-wide galvanized metal flashing is required.

Installation Notes

Installation is typically performed by licensed roofers or sheet metal contractors. Wear appropriate cut-resistant gloves when cutting and bending galvanized sheet metal, as edges are sharp. Follow local building code requirements and manufacturer roofing system guidelines for overlap dimensions and fastener spacing. Ensure the substrate is clean and dry before applying any sealant or lap cement alongside this flashing.
