A premium, UV-stabilized polypropylene underlayment that provides a critical extra layer of protection between your shingles and your roof deck. Conventional organic felts can absorb moisture, causing buckling and wrinkling that can impact the look of your roof. Tiger Paw™ premium roof deck protection combines strength and long term durability breathability to help protect your home against wind driven rain. Tiger Paw™ premium roof deck protection is a key part of the GAF lifetime roofing system and has earned the good housekeeping seal.

• Resists wrinkling and buckling that can "telegraph" through your roof shingles and detract from its finished appearance
• Specially designed surface helps provide excellent walkability for installers versus conventional felts or typical synthetic underlayments
• Synthetic, non-woven construction provides at least 600% (i.e. 7 times) greater tear strength than standard #30 felt
• Non-asphaltic, polypropylene construction will not rot or become brittle - unlike conventional felts, which can disintegrate over time
• May also be used with non-asphaltic systems, such as slate, wood, metal or tile
• Resists UV degradation for up to 180 days
