IKO RoofGard-Cool Series 520021 Roofing Underlayment, 250...

Our RoofGard-cool gray rolls are lighter and easier to handle making it faster to install. The synthetic, non-breathable material provides a great slip-resistant surface. It is easy to install around vents, dormers and other roof structures. And since it's gray instead of black, it absorbs less of the sun's radiant heat. Lay lines every 1 in (2.5 cm) aid in shingle course alignment.

• Superior slip-resistant surface allows roofers to walk on it safely during dry installations
• Gray color helps the roof's micro-climate stay cooler, more comfortable
• Synthetic, non-breathable material is completely water-resistant, effectively shedding water that gets behind shingles or alternative roofing materials
• Extremely flexible, even in cold weather so it won't crack, peel or delaminate and is easy to install around vents, dormers and other roof structures
• Lay lines every 1 in help installers align shingle courses with ease and precision
• Multi-layered construction with a high-strength polypropylene core for outstanding tensile strength, durability and tear-resistance
• Tough polyolefin coating on top and bottom layers provides superior weather-resistance
• Thanks to UV-stabilizers, you can leave it exposed for up to 3 months without experiencing break-down or performance loss
