WWII Hangar B: This project consists of installation of a new roofing system on a Countyowned hangar at Middle Georgia Regional Airport (MCN). Known as WWII Hangar B, this building is comprised of two arching metal roofs that meet at a center metal roof gable over the hangar, and a lean-to metal roof section over offices along the side opposite the hangar doors. The roof area is approximately 25,250 square feet. These roofs will receive new insulation over the existing metal roof to support new PVC roof membrane. Work will include the replacement of all gutters and downspouts, new gutters, raising of equipment curbs and vents, and new metal flashings. Macon-Bibb County recently installed a new PVC roof on the adjacent WWII Hangar A in a similar fashion. Embraer Roof: This project consists of installation of a new roofing system on an office building and with hangars totaling approximately 160,000 square feet. There are five roofs that comprise the Embraer facility at MCN - one is currently an R-Panel single skin metal roof attached directly to the building structure and the remaining four roofs have a single skin standing seam metal panel roof attached directly to the building structure.
