What ABC Supply does
ABC Supply Co. Inc. is the largest wholesale distributor of roofing and exterior building products in North America, headquartered in Beloit, Wisconsin. Founded in 1982 by Ken and Diane Hendricks, the company serves professional contractors through a network of over 1,000 branch locations spanning 49 U.S. states and Canada, supported by a workforce exceeding 20,000 associates. Product lines include steep-slope and low-slope roofing, siding, windows, doors, stucco, decking, insulation, roofing accessories, and renewable energy equipment, distributed to roofing, siding, window/door, and exterior finishing contractors.
The company's technology stack centers on three proprietary layers: myABCsupply (an online ordering and mobile app platform enabling 24/7 contractor self-service and account management), ABC Connect (an integration ecosystem linking to 16+ third-party contractor software platforms including Acculynx, EagleView, GAF QuickMeasure, HOVER, JobNimbus, Leap, Roofr, and ServiceTitan), and a public REST API providing real-time access to product, pricing, order, account, location, and notification data. ABC Supply operates a proprietary delivery fleet with specialized vehicles including conveyor-equipped flatbeds for rooftop material placement, and has run an internal AI program for eight years focused on fleet and inventory management, with a Prokeep-powered AI Order Engine piloted in 2025.
Revenue is generated through wholesale product distribution, delivery and logistics services, and value-added contractor services (tapered insulation design, solution center consultations, automated manufacturer rewards processing, and customer credit programs). The business operates on a sales-led, decentralized branch model supplemented by self-service digital ordering and enterprise API integrations. The company is privately held and wholly owned by Chairperson Diane Hendricks following the 2007 death of co-founder Ken Hendricks, and has grown through a series of major acquisitions including Bradco Supply (2010), L&W Supply (2016, rebranded ABC Supply Interiors in 2026), Town & Country Industries (rebranded ABC Supply Outdoor Solutions in 2026), America Building Materials (2024), and Koch Building Products (2026).

Direct peers
- SRS Distribution: SRS Distribution is one of the largest U.S. wholesale distributors of roofing and building products serving professional contractors. Now owned by Home Depot, SRS is the closest direct competitor to ABC Supply in branch density, product mix, and contractor-focused service model.
- Foundation Building Materials (FBM): FBM is a specialty distributor of building products including roofing, insulation, drywall, and metal framing, serving professional contractors across North America. Closely comparable to ABC Supply in category mix and contractor-focused go-to-market.
- QXO / Beacon Roofing Supply: Beacon Roofing Supply (acquired by QXO) is a major U.S. distributor of roofing and complementary building products to contractors. It operates hundreds of branches across North America and competes head-to-head with ABC Supply in steep-slope roofing, siding, and waterproofing categories.
- BMC Stock Holdings: BMC Stock Holdings (now part of Builders FirstSource) is a major U.S. distributor of building materials to professional contractors, with significant overlap in roofing, siding, windows, and millwork. Comparable in customer base and product breadth, with strong presence in single-family residential construction.
- L&W Supply (now ABC Supply Interiors): L&W Supply, which was acquired by ABC Supply in 2016 and rebranded as ABC Supply Interiors in 2026, distributed drywall, ceilings, steel framing, and interior building products.

Broad incumbents
- SiteOne Landscape Supply: SiteOne is the largest U.S. wholesale distributor of landscape supplies, including irrigation, lighting, hardscapes, and nursery goods, to professional contractors. A broad incumbent demonstrating the value of a specialty distribution model, though focused on landscape rather than roofing.
- White Cap (formerly HD Supply Construction): White Cap is a large, broad-line distributor of construction supplies and tools to professional contractors in the U.S., serving concrete, drywall, mechanical, and exterior categories. Larger and more diversified than ABC Supply, it is a broad incumbent rather than a roofing-focused specialist.
- Pool Corporation: Pool Corporation is the largest global wholesale distributor of pool and related backyard products, with a similar high-touch, pro-contractor distribution model and comparable scale. Useful as a benchmark for specialty distributor economics and valuation, though not directly overlapping in product.
- Ferguson Enterprises: Ferguson is the largest U.S. wholesale distributor of plumbing, HVAC, waterworks, and related specialty products. A broad incumbent comparable in scale and B2B contractor distribution model, but operating in adjacent categories rather than roofing and exteriors.
