Riverhead Building Supply

What Riverhead Building Supply does

Riverhead Building Supply Corp. (RBS) is a privately held, full-service building materials distributor founded in 1948 and headquartered in Riverhead, NY, on Long Island. The company operates 23 locations across Long Island and New England (Connecticut, Massachusetts, and Rhode Island), supported by a fleet of 200+ customized trucks — including boom, spider, and box vehicles — that provide jobsite delivery. Its product portfolio spans lumber, roofing, siding, decking, masonry, drywall, flooring, insulation, hardware, tools, windows and doors, skylights, cabinetry, moulding and trim, architectural hardware, and paint and stain, sourced from more than 500 brand partners including Marvin, Andersen, James Hardie, GAF, Boise Cascade, Weyerhaeuser, Medallion, Miralis, Tedd Wood, Plain & Fancy, DeWalt, Milwaukee, Makita, and PPG. RBS serves two primary customer segments: professional builders and contractors (the dominant segment, supported by dedicated outside sales specialists, professional estimating, and truss/EWP design) and homeowners (served through 11 kitchen design showrooms operated via the wholly-owned Lakeville Kitchen & Bath subsidiary, an e-commerce storefront at shop.rbscorp.com, and installation services for windows, doors, and garage doors). The company expanded geographically in 2020 by acquiring Rhode Island–based United Builders Supply, marking its move beyond Long Island into New England. Revenue is generated through one-time product sales, professional services (estimating, design, installation), and project-based quoting; pricing is not publicly disclosed. The business is independently owned, with no disclosed venture capital, private equity, or parent-company ownership.

Direct peers

• 84 Lumber: 84 Lumber is one of the largest privately held building materials suppliers in the U.S., operating a network of stores and component manufacturing facilities serving professional builders. Like RBS, it distributes lumber, engineered wood, windows, doors, and millwork to contractors and DIY customers, with in-house truss/EWP design and jobsite delivery capabilities.
• US LBM: US LBM is a large national distributor of lumber, building materials, and specialty products serving professional builders, remodelers, and homeowners. Its portfolio of regional brands and focus on contractor relationships across multiple states directly parallels RBS's regional-distributor-plus-acquisition model.
• ABC Supply Co. ABC Supply is the largest wholesale distributor of roofing, siding, windows, and exterior building products in North America. It competes with RBS in the contractor-grade exterior products category (James Hardie, GAF, Andersen, Marvin) and shares a similar pro-focused GTM with branches and delivery fleets.
• Lansing Building Products: Lansing Building Products is a national distributor of exterior building products—windows, siding, roofing, doors, and trim—serving professional contractors across the U.S. It is comparable to RBS in the specialty exterior products category and shares a similar contractor-driven distribution model.
• SRS Distribution: SRS Distribution is a national wholesale distributor of roofing, siding, windows, and building products serving contractors. Like RBS, it focuses on the pro contractor channel with branch-based distribution and complementary exterior product categories.
• BMC Stock Holdings: BMC Stock Holdings (now part of Builders FirstSource) was a major regional and national supplier of building materials, including lumber, millwork, windows, doors, and component solutions, serving production and custom homebuilders. It directly parallels RBS in product mix and builder-focused GTM in select overlapping markets.

Broad incumbents

• Builders FirstSource: Builders FirstSource is the largest publicly traded supplier of building materials, manufactured components, and construction services to professional homebuilders in the U.S. It is comparable to RBS in product mix and customer base but operates at vastly greater national scale and includes component manufacturing.
• Ferguson: Ferguson is a large publicly traded distributor of plumbing, heating, cooling, and specialty building products. While its core category is plumbing/HVAC, its contractor distribution model, showrooms, and design services overlap with RBS's kitchen & bath design and contractor delivery capabilities.
• Home Depot: Home Depot is the largest home improvement retailer in the U.S., selling lumber, building materials, tools, and appliances to both DIY consumers and professional contractors via its Pro Xtra loyalty program. It competes with RBS across virtually all product categories but at vastly larger national scale and with a stronger e-commerce platform.
• Lowe's: Lowe's is the second-largest U.S. home improvement retailer, offering lumber, building materials, appliances, and tools with a growing focus on the pro contractor segment. Like Home Depot, it competes with RBS broadly in retail building materials but at national scale and with deeper digital and private-label capabilities.
