The Roofing Contractor's Association of Southern California was established originally in 1940 as the Union Roofing Contractor's Association in order to counteract the growing weight of organized labor, and to attempt to clear up the chaos of prices and restrictions that existed even then. It was incorporated in 1950 as a non-profit corporation and the name changed to "Roofing Contractor's Association of Southern California, Inc.", and has grown from its eleven original founders to its present size.
