IKO Stormtite Series 520024 Roofing Underlayment, 250 ft ...

IKO Stormtite® synthetic underlayment is engineered to be used under asphalt shingles. And it has qualified as an IKO's PRO4 roofing component. It is a cost-effective alternative to traditional #15 asphalt saturated felt, and is covered by a limited 15 year material warranty.

• Stronger than felt, Stormtite® is more resistant to tearing and shredding when installers walk on it
• It's coated top and bottom with tough polyolefin for superior weather-resistance with a slip-resistant surface
• More flexible, even in cold weather, Stormtite® is easy to install around vents, dormers, skylights and other typical roof structures
• Lays flat without curling and is super durable
• Synthetic, non-breathable material, Stormtite® effectively sheds water that gets behind shingles and it's engineered to be a vapor-retarder
• Thanks to built-in UV stabilizers, it can be left exposed for up to 30 days and will continue to perform
• Lighter than felt, a single roll of Stormtite® contains 1000 sq-ft but weighs only 20 to 26 lb
• It's easier for your installers to handle
