Hendricks, born and raised in Janesville, Wisconsin, was a high school dropout who joined his father in the roofing business, reshingling houses on weekends.

After giving the company to the employees so he would have more personal time, he started ABC Supply in 1982 with Diane Hendricks by purchasing three failing Bird and Sons locations.

Hendricks was involved in efforts to build a new stadium for the Beloit Snappers minor-league baseball team, and was the developer of a residential plot in Janesville.

Hendricks died at age 66 on December 21, 2007, in Afton, Wisconsin, when he fell through a sub floor under construction and into the garage of his home.

[5] He left behind his wife, Diane Hendricks, and seven children, Kendra, Kim, Kathy, Kevin, Brent, Kara, and Konya.
