Contractor repairs roof, prevents leaks
Sam Pearce, contractor, places a panel on the roof of a water pump station at Shaw Air Force Base, S.C., July 27, 2017. Contractors repaired the roof as part of an on-going project to convert base buildings with flat roofs to slanted metal panels to prevent leaks and damage caused by rain.
