Synthetic Roofing Underlayment
48″ × 250′ Roll
Lightweight synthetic underlayment for asphalt-shingle, metal, and tile roof assemblies. Lays flatter than felt; doesn't tear in wind.
Polypropylene synthetic underlayment in standard 48-inch × 250-foot rolls — exactly 1,000 square feet (10 squares) per roll, the math that matches a roofer's takeoff. Lighter to carry up a ladder than #15 felt, lays flatter, walks better in heat, and won't fishmouth or tear after a windy install delay. Suitable as a primary underlayment for asphalt-shingle, metal, and tile roof systems.
