Ken and Diane Hendricks of Hendricks Holding Company

In the early 1970’s, Diane and Ken Hendricks began their businesses by investing in real estate in Beloit, Wisconsin, while simultaneously owning and operating a national roofing company. In 1982 they founded American Builders and Contractors Supply Co., Inc. (ABC Supply) by utilizing the knowledge gained from their roofing business. ABC Supply transformed a roofing distribution industry that was manufacturer owned and operated with a single brand, to an independently owned and operated network with multiple brands and a nationwide footprint, with locations to serve roofing customers in every major market in the United States.

Since its founding, ABC Supply has revolutionized the roofing material distribution business. Today, ABC Supply is the largest wholesale distributor of roofing products in the United States and one of the largest distributors of siding, windows, drywall, and other select exterior and interior building products. It is also a 15-time proud recipient of the Gallup Great Workplace Award, which recognizes the best-performing workforces in the world.

HHC was established in 2001. HHC is a continuation of Diane and Ken’s dreams, and a representation of their combined visions. The businesses, and all of their associates, share a common passion for the values that Diane and Ken followed, and continue to follow, in pursuit of the American dream. Their foundation is clearly defined by seven core values: Respect, Opportunity, Work Hard – Have Fun, Entrepreneurial Spirit, Family, Give Back, and American Pride.




Hendricks Holding Company is comprised of committed, talented, and thoughtful people who aspire to improve our companies’ performance as well as the communities within which we work and live.  Our most important assets are our people, capital, and reputation.  We are committed to a culture of integrity, entrepreneurship, and achievement.
