Company Background

Twin City Roofing was established in 1927 by B.J. “Bud” Williams. The company was first located in Fargo-Moorhead, and was later moved to Wahpeton-Breckenridge. O.L. “Hoot” Harr began working for Williams in 1951. The company then established an operation in the Mandan-Bismarck area where the company headquarters is now located. In the late 1960’s a warehouse was built in Dickinson to better serve the customers in the western portion of the service area.

Marv Miller started with Twin City Roofing in 1979 as an estimator / project manager. Scott Harr began with the company in 1986. Scott worked in the field before transitioning into sales and management. Together they purchased Hoot Harr’s interest in the company.

In 2018, Marv announced his retirement, and his shares were purchased by Scott Harr and JasonvGeigle. Jason was then promoted to Vice President.

As co-owners, Scott and Jason strive to improve upon the company’s longstanding tradition of quality workmanship, excellent service, and the principles of dedication and reliability to their customers that Twin City Roofing was founded on.
