APOC Tuff-Grip™ 15 is a UV-stabilized polypropylene underlayment designed to shed water. It provides a secondary layer of protection against wind, moisture, and other elements and replaces the use of #15 and #30 organic roofing felt under asphalt shingles, residential metal and cedar shake roofing materials. 
Designed with a high-traction, slip-resistant surface, Tuff-Grip™ enhances safety and productivity — even on steep slopes. Its UV-resistant composition provides reliable protection during extended exposure, while its lightweight yet robust construction ensures superior defense against moisture, wind, and harsh weather.
