Our Beginnings

Dial One Roofing of Oregon, Inc. had humble beginnings. It started as a partnership in 1979 named Tri-County Roof Service, focusing on treating moss on roofs and sidewalks. The process involved spraying a zinc-based product and letting it disintegrate, which was effective but time-consuming due to the lack of pressure washers back then.

beginningsThen on May 18th, 1980, Mount Saint Helens erupted, covering everything in sight with 2 to 3 inches of ash. Every roof, gutter, yard, patio, and furniture had to be cleaned off and the ash disposed of. The company purchased two pressure washers and started pressure washing roofs to remove moss and ash, which turned out to be a constant source of work for four years.

Real roofing experts

In 1984, the company and all assets were purchased from the previous owner, and the company started offering roof installation services. Two years later, the company franchised by the Dial One Services Group. Since then, Dial One Roofing has been providing commercial and residential roofing services in the Northwest area. In the late 80s, the company expanded its services to include roofing, commercial flat roofing, metal roofs, roof repair services, skylights, and deck membranes.

Today, Dial One Roofing of Oregon, Inc. is the authority on quality roofing in the Portland, Oregon area. The satisfaction of its customers is what drives the company to be the best it can be every single day.
