Our story
Twin City Roofing Co. was founded in 1927 by B.J. "Bud" Williams. Built on honest work and craftsmanship, the company specialized in "hot tar roofs" and began serving the Wahpeton-Breckenridge area, laying the groundwork for a reputation that would last generations.
In 1931, the original office and warehouse was constructed in Wahpeton. Only a few years later, an addition was built, doubling the size of the original facility due to rapid growth.
In 1951, O.L. "Hoot" Harr joined the company, bringing the same pride, reliability, and care that defined Twin City Roofing from the start. In 1953, he was relocated to Mandan to establish operations in Central North Dakota to better serve its customers.
In 1975, a warehouse was built in Dickinson, strengthening our ability to serve customers across Western North Dakota - without taking shortcuts or compromising quality.
A legacy that still sets the standard
In 1979, Marv Miller joined Twin City Roofing as general manager, continuing the tradition of doing the work right and standing behind it. That same year, Twin City Roofing became an authorized applicator for Carlisle Sure-Seal rubber roof membranes, ushering in the era of single-ply roof systems done right.
In 1982, Twin City Roofing became an approved applicator for Firestone Tire and Rubber Company's building products division, diversifying the company's membrane roof systems product offerings.
In 2018, Marv Miller announced his retirement. His shares were purchased by Scott Harr and Jason Geigle, and Jason was promoted to Vice President, continuing the company's tradition of leadership grown from within the team.
In 2025, Jason Geigle became the sole owner, to carry forward what Twin City Roofing was built on: quality workmanship, dependable service, and a promise that our word means something.
