3M™ Classic Roofing Granules are a unique, natural mineral product, the only type of roofing granule that meets the toughest test of time, weather and the marketplace.
Our granules are dense and non-porous, resist ultra-violet light and are tough enough to stand up under handling. And, they hold the long-lasting ceramic coatings added to create the ever-growing selection of colors demanded by the roofing market.
