This is a roofing project specification document for Newaygo High School in Newaygo, Michigan, prepared by Tower Pinkster Titus Associates Inc. The project involves a comprehensive roof replacement for multiple roof areas (A, B, C, D, E, G, H, J, K, L, and M) of the school facility. The specification details a complete roof tear-off down to the existing metal deck for most areas, with a new roofing system consisting of a 60-mil EPDM membrane fully adhered to polyisocyanurate insulation layers. The work includes installing tapered insulation with a minimum 1/8-inch per foot slope, replacing existing wood nailers with pressure-treated wood, and addressing roof penetrations, drains, and edge details.

The roofing system specifications require a 20-year no-dollar-limit full roof system warranty from the membrane manufacturer and a two-year installation workmanship warranty from the contractor. The project includes detailed requirements for insulation layers, membrane installation, flashing, and accessories, with specific attention to maintaining proper drainage and waterproofing. Core samples of existing roof compositions are documented for each roof area, revealing various existing membrane and insulation types. The project appears to be part of a broader school improvement initiative, potentially including secure vestibule additions and mechanical room upgrades, with the roofing work being a critical component of the overall facility renovation.
