QXO, Inc. is the largest publicly-traded distributor of roofing, waterproofing, and complementary building products in North America, operating approximately 600 branches across the United States and Canada. The company serves over 110,000 residential and non-residential customers—including professional contractors, home builders, and retailers—with an extensive range of professional-grade exterior products including asphalt shingles, single-ply membranes, siding, windows, doors, and insulation, alongside value-added services such as technical support and last-mile delivery. QXO generates revenue through product sales and services, benefiting from structural growth drivers including aging housing stock that drives repair and re-roofing demand, and the fragmented nature of the roofing distribution sector, which presents opportunities for organic expansion and accretive acquisitions.
