Summary
Project consists of 52,400 SF roof replacement of elementary school. Approx. 45,400 SF of the existing roof will require tear-off of gravel-surfaced built-up membrane and insulation down to the original metal decks - new insulation system shall be tapered polyisocyanurate foam boards with 5/8" fire code gypsum board on the deck. All insulation to be mechanically attached. Provide tapered insulation as shown on roof plans. The replacement membrane assembly consists of the application of a 60 mil. KEE single-ply membrane mechanically attached through the insulation assembly to the metal deck; 7,000 SF will require removal of existing gravel surface and built-up flashings prior to an over-roof using 1/2" glass-faced cover board and the same KEE membrane, all mechanically fastened to the deck. Scope of Work includes installation of new perimeter wood nailers and edge metal. Roofing system installation shall require a final inspection by the Membrane Manufacturer and will be eligible to receive a 20-year material and labor warranty covering the full- system including the insulation and membrane.
