Our Beginnings

Dial One Roofing of Oregon, Inc. began as a partnership in 1979 under the name Tri-County Roof Service, for the treatment of moss on roofs and sidewalks. The process was to spray a zinc-based product on the moss and let it disintegrate. While the method was effective, it was by no means fast. Pressure washers were not a standard item then and were very expensive if you could find them at all.

Beginning then on May 18th, 1980, it happened… Mount Saint Helens explodes pouring 2″ to 3″ of ash on everything in sight. Every roof needed to be cleaned off, every gutter cleaned out. Yards, patios, and patio furniture all had to be cleaned off, and the ash removed and disposed of. We purchased two pressure washers and went to work. Fortunate for the company, the ash made moss grow on everything at an unstoppable rate; therefore constant work was available. For four years we did nothing but pressure wash roofs to remove moss and ash.

A Roofing Company is Born

In 1984, the company and all assets were was purchased from the previous owner, and at that time roof installation services was added to our lineup. In 1986, we franchised by the Dial One Services Group.

Ever since we have been installing commercial and residential roofing in the Northwest area, in the late 80’s we added roofing, commercial flat roofing, metal roofs, Roof repair services, and skylights, and deck membranes to our services. As of today, we feel we are and strive to be the authority on quality roofing in the Portland, Oregon area. The satisfaction of our customers drives us every single day to be the best we can be.
