Roofing & Waterproofing

JRS Engineering provides roof design and consulting services throughout the Pacific Northwest. Since founding JRS in 1998, we have become a leader in the roof consulting field. Our goal for all projects is to work with property managers, owners and contractors to cultivate high-performance, aesthetically rich buildings that deliver greater durability, energy performance and value to our clients. 

JRS combines a thorough knowledge of building science with a practical understanding of the construction process to implement technically-sound, cost-effective roofing solutions. We recognize that each of our clients has unique needs—and we know that practical and economical solutions are required to maintain the high standards for which we have become known. 

With more in-house roofing expertise than our competition, we can offer quality consulting and RCABC inspection services for any type of roofing or waterproofing project.
