Summit 60 Roof Underlayment

A synthetic alternative to #15 felt, Summit® 60 underlayment provides enhanced protection against water and mold growth. Made with a woven polymeric scrim, Summit® 60 features increased strength, reduced slippage between the underlayment and the roof sheathing and improved walkability during installation. This high-quality synthetic roof underlayment will not buckle, warp or crack over time like organic felt and the UV coating allows for 60-day exposure to the sun while the roof is being installed.
