About this file
This document is a roofing specification for a section of the Central Administration building located at 4000 Cooper St. in the Southern Region. The document outlines three roofing system options for the approximately 6,000 square foot roof section 27: 1) a full roof replacement with a mechanically attached EPDM system, 2) a restoration specification to apply a coating over the existing EPDM roof, and 3) a full removal and replacement with a fully adhered EPDM system. The existing roof is identified as being in fair condition at approximately 15 years old. Replacement costs are estimated at $51,600, restoration costs at $6,000, and the alternate fully adhered system at $7,500. All specifications include a 15-year manufacturer's warranty.
The document provides detailed technical requirements for each roofing option, including insulation, flashing, drainage, and other roof components. It notes that the existing roof could not be fully inspected due to restricted access. The document is intended to provide budgetary cost information and technical specifications for the roofing project.
