PABCO® Roofing Products began manufacturing premium asphalt shingles in Tacoma, Washington in 1984. PABCO quickly earned a reputation for producing quality products and providing excellent customer service. Our product offerings have expanded over the years - including Paramount®Advantage, Paramount®, and Cascade™, which was awarded U.S. Patent No. D589, 172S for its unique design - but our commitment to quality has remained, and is one of our core values.
