A.C.E. Building Service installed this 14,500-square-foot Butler® MR-24®roof system to replace an existing screw-down roof, which was uninsulated and in very poor condition. A.C.E. crews removed the existing roof panel and installed six inches of insulation under the new MR-24 roof panels. All the original 1950s-era roof purlins were able to be reused with no structural modifications. The project also included a custom fabricated stainless steel internal gutter.
