Principia tracks over 14,000 points of distribution in the U.S. for residential roofing products; almost 4,500 are lumberyards. Although specialty one-step dealers accounted for the bulk of residential roofing product sales in 2018, lumberyards sold $1.8 billion of residential roofing products in the United States, or roughly $300 million in gross profit for lumberyards.
