The Project consists of the removal of approximately 10,300 SF of existing membrane and shingle roofing and insulation to decking, as well as existing flashings. The Project also consists of partial and gentle removal of membrane from existing historic terra cotta cornice. The roof will be replaced with a new roofing system: The upper portion is comprised of polyisocyanurate insulation, coverboard, EPDM membrane, walk pad surface, new flashing, new scuppers, and associated blocking and nailers. The sloped portion is comprised of an eave protection membrane, nail based insulation panels, architectural shingles, and associated blocking and nailers. The membrane at the cornice requires gentle partial-removal and will be covered in a fluid-applied membrane. With increased height of insulation, rooftop equipment including vents, pipes, ducts, roof hatches, and associated curbs will need to be salvaged and reinstalled. Existing roof drains to be replaced with new. Existing skylights to be replaced with new. The existing elevator overrun will be clad in a metal rainscreen. The electrical equipment mounted to it currently will need to be reinstall with proper waterproofing and flashing.
