Expert Verdict — Reviewed by the SuperArbor Pro Desk
Ice & Water Shield is the go-to membrane for eaves and valleys where ice damming and wind-driven rain are concerns. Roll it out onto a clean, dry deck, avoid stretching, and lap per the printed lines and the manufacturer's instructions. In cold climates or high-wind zones, running it the full length of eaves and all valleys is standard best practice; check local code requirements for ice barrier coverage.
Install on a clean, dry deck using proper roof fall protection, and follow the manufacturer's application instructions and local building codes.
