Jumbo Tex 2-Ply Building Paper brings contractor-grade protection to every roofing project. Engineered as a durable underlayment, this heavy-duty, two-ply building paper creates a reliable moisture barrier between roof deck and shingles—helping to guard against wind-driven rain, ice dams and everyday wear. Its flexible design makes it easy to handle, cut and install around roof vents, chimneys and complex flashing details, while its smooth surface provides a consistent base for a wide range of roofing materials.

Whether you’re tackling new construction or a reroof, Jumbo Tex 2-Ply ensures consistent coverage across gables and valleys. Its breathable composition allows trapped moisture to escape, reducing the risk of rot and extending the life of your roof deck. Lightweight yet tough, it stands up to jobsite handling without excess bulk, so you get fast, efficient installation without compromising performance.
