Ridout was started in 1971 by Homer L. Ridout and his son Wayne Ridout. Many members of the family worked in the business over the years, including Wayne’s wife, Robbye Ridout, son, Ross Ridout, and two daughters, Kristen Ridout Smith and Kari Ridout Rockwell. All of these family members were active in the business at the time of the acquisition by US LBM in 2017, with Ross Ridout staying on as President following the transition. US LBM, the company which acquired all of the Ridout companies in 2017, is one of the largest specialty building materials distributors in the United States. US LBM operates a network of 36 leading specialty building companies across the United States. US LBM implements the philosophy of local autonomy and leadership to capitalize on the premier reputation of its operating companies and local customer relationships. For this reason, the Ridout companies still operate under the Ridout name.
