Clow Roofing & Siding

Clow Roofing has been the established roofing company of Portland and SW Washington for over 95 years. From the initial walk through to final inspection, we give you the individual attention necessary to ensure a smooth process and quality installation. Roofing commercial buildings is a very large investment of both time and money. Anything short of Clow's extraordinary service and quality workmanship could end up being a false economy. You will always be able to find a less expensive way to re-roof your building.
