Customer Satisfaction Is Our Top Priority

We know from 45 years of commercial roofing experience that customer satisfaction is the best way to grow as a company. Providing quality workmanship, with the best materials, and constant communication with our customers is how we accomplish this.
Our Company Mission
SQI lnc.’s mission is to provide our employees with an honest and helpful working environment, where employees, individually and collectively, can dedicate themselves to providing our customers with exceptional workmanship, extraordinary service, and professional integrity. Our commitment to this mission allows SQI to maintain its position as a premier roofing and sheet metal company.
Our Story
SQI began as a Seattle roofing contractor more than 45 years ago, and has grown into a roofing contractor Washington customers can rely on for a myriad of commercial roof systems. 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.
