Waterproofing System for Metal Roofs
Step by Step Application Process
1Apply Seam Tape to All Metal Roof Seams – Lap Seams, Penetrations, Transitions, Holes
We apply this polyester-reinforced butyl seam tape to all ridge cap and end lap horizontal seams, vertical seams with more than a 1/4 inch gap, penetration seams including curbs, vents, stacks, and transition seams, including wall rakes and end rake seams. This is the first in a two-step process we call theWaterproofing System in which we seal and protect all water entry points.
2Top-Dress (Apply) Acrylic Patching Cement to All Seam Tape and Fasteners
We apply this acrylic patching cement overtop of all seam tape applied in the previous step, and also to all other entry points such as fasteners and roof holes. This is the second in a two-step process we call theWaterproofing System in which we seal and protect all water entry points.
