Our Company Mission
SQI began as a Seattle roofing contractor in 1972, and has grown into a roofing contractor Washington customers can rely on for a wide variety of commercial roof systems and services. We concentrate on commercial roofing and industrial roofing markets for both re-roof projects and new construction. We added sheet metal copings and flashings many years ago to complete the roofing system process, which led to the natural development of architectural sheet metal roofing. SQI works hard to continually evolve in concert with technology changes in the roofing business, and as a result has become the premier commercial roofing, maintenance, and repair company in the Northwest.
