Roofing underlayment is water’s toughest opponent, creating a secondary water barrier that reduces the incidence of leaks caused by storm damage, wind-driven rain, ice dams and worn roofing materials. K&D roofing underlayment is one more component in the line of defense against the elements. It even protects homes from moisture during the construction process, serving as a temporary water-resistant covering.
