Duro-Last® Roofing has been manufacturing single-ply membrane for Oregon flat and low sloped roofs since 1978. Duro-Last® Roofing started in Saginaw, Michigan. Due to our rapid growth a manufacturing plant was needed in the west coast. Over 30 years ago Duro-Last® opened in Grants Pass, Oregon. Since 1987 we have been manufacturing our custom fabricated roofing and edge metal right here in Oregon. Class A Roofing Consultants, located in Portland, are our independent sales representatives for Oregon. We have over 100 highly qualified contractors installing roofs in Portland, Eugene, Salem, Roseburg, Medford, Brookings, Coos Bay, Tillamook, Astoria, Bend, Hood River, The Dalles, Pendleton and every city in between.
