Tracing its origins to 1977, Carriere-Stumm is one of the premier contractors in the southern U.S., focusing a large portion of its business on commercial roofing projects. Headquartered in New Orleans, Carriere-Stumm has been highly instrumental in the rebuilding of the New Orleans and Mississippi Gulf regions after Hurricane Katrina, and in recent years they have shifted much of their focus toward sustainable "green roofing" solutions.
