Gator-Skin is a high quality roofing underlayment designed to shed water off your roof and away from your home. It is manufactured using a three layer construction that won't tear or wrinkle like traditional products, even when soaking wet. Its durable and tough composition can withstand the desert heat, pouring rains, high winds and ice and snow. This product provides a secondary layer of protection against moisture, wind, and other elements and replaces the use of #15 and #30 organic roofing felt under asphalt shingles, residential metal and cedar shake roofing materials. It also utilizes Safe-Step Technology which is designed to provide enhanced traction and walkability. Gator-Skin is the ideal underlayment for professional roofing contractors that demand performance.
