From a single asphalt shingle manufacturing facility in 1982, Atlas has grown to 36 facilities in North America providing worldwide product distribution. Today, products from the company’s four major divisions, Polyiso Roof & Wall Insulation, Shingle & Underlayment, Molded Products, and Web Technologies, are manufactured in state-of-the-art facilities and shipped from our network of manufacturing plants and distribution facilities in the United States, Canada, and Mexico. It’s amazing how our customer-first philosophy has grown on our clients.
