“Many years ago, my first job in civil engineering was a facilities engineer designing and inspecting roofing projects. I’d like to think I can still recognize an outstanding roofing job. The estimate was very thorough, clearly presented and superior to other estimates. Also your firm was recommended by Puget Sound Checkbook. First rate job from start to finish.”
