Gutter and Downspout Specialists
Custom Sheet Metal Work & Architectural Metal Roofing

Since 1950, Columbia Sheet Metal has been creating high quality metal roofing and continuous gutters for commercial and residential projects. We offer a wide range of products such as copper bay windows and custom flashings. The oldest and most experienced supplier of continuous gutters in Washington state, Columbia provides the finest materials, dependable service and skilled craftsmanship.

Each of our projects is handled with care on an individual basis, from design to installation. And since we do not hire sub-contractors, we can provide greater scheduling control as well as local warranty and service. Our products were used on the
Super House in Yokohama, Japan. For the do-it-your-self-er we now offer a complete Roof in a Box kit. Everything you need, including detailed instructions, is included.
