Our Story
In 1996, Mark Carpenter started Columbia Construction Services, Inc. dba, Columbia Roofing, and Sheet Metal. The company started by doing small repairs that built into a successful business model of helping owners make financial sense out of roofing repairs and replacement.
While the average roofing company stays in business just five years or less, Columbia Roofing and Sheet Metal have spent more than a decade in the rain-soaked Pacific Northwest putting roofs over the things that people care about most. So whether it’s a question you need to be answered, or maintenance and repair issues that need addressing, you can rely on the fact that Columbia Roofing and Sheet Metal will be around to take care of you, your building, and your business.
Columbia Roofing & Sheet Metal now does work in Oregon, Washington, Idaho, and California with a year-round staff of over 60 people. Columbia provides 24/7 leak repair service, full commercial replacement, and recovers, sheet metal work and roofs, plus commercial repairs and maintenance. The company’s statement tells you how they do business, “Expert Solutions, Guaranteed Results”, it’s just how we do business.
