48268 Roofing Underlayment, 36 In X 67 Ft, Self-adhering

This MFM Building Products self-adhering roofing underlayment provides essential wind and water protection for your roof system. The 36-inch by 67-foot roll creates a reliable moisture and air barrier that shields your roof deck from wind-driven rain, freezing rain, and water infiltration. Whether you're installing a new roof or replacing an old one, this underlayment enhances durability and helps prevent costly water damage to your home or building.

The product features a high-temperature rubberized asphalt adhesive that bonds securely to the roof substrate and seals around fasteners to limit damage caused by water penetration. This aggressive adhesive design minimizes gaps and weak points where water can penetrate. The split release liner makes installation easier when working in valleys, ridges, and around chimneys. This underlayment works effectively under shingles, tile, shake, and metal roofing systems, making it a versatile choice for residential and commercial applications.
