Product Overview
The Eco Blue Breathable Underlayment helps protect your home and reduce trapped moisture at the same time. It provides a critical extra layer of protection between your shingles and your roof deck to help prevent wind-driven rain (or water from other sources) from infiltrating under your shingles and causing damage to your roof structure or to the inside of your home.
