3M™ Classic Roofing Granules are dense, non-porous, UV ray resistant, and tough enough to stand up under handling. Made of a natural mineral product coated in ceramic, the granules meet the toughest tests of time, weather and visual appeal. Prime roofing granules are the protective pixels of beautiful shingles. It’s from 3M’s expertise and long history in mining and geology, starting over 100 years ago in Two Harbors Minnesota, which allow us to create such a durable yet beautiful product. Through advances in mineral crushing, color coating and treatments, 3M roofing granules enable shingle manufactures to design beautiful roofing styles and colors in an array of choices and specialty features.
