The purpose of this Corrosion Prevention and Control CPC demonstration was to investigate the life-cycle cost impact of three corrosion-resistant roofing technologies that provide several secondary benefits over the outdated roofing systems they replace. Fort Bragg, NC, was selected as the location to demonstrate 1 a heat-resistant metal shingle roofing system with above-sheathing ventilation ASV, 2 a sloped-roof conversion using standing-seam metal roofing system with heat-shedding coating, and 3 a fiberglass-reinforced plastic FRP panel roofing system with ultraviolet UV radiation protection. Metrics were established to evaluate improvements in performance, corrosion resistance, and energy efficiency over older conventional roofing. Performance was documented through data collection, observation, and reports by facility users. None of the demonstrated technologies was found to provide sufficient return on investment ROI to warrant their selection solely to improve building energy efficiency. The ASV and slope-conversion methods could be modified to reduce first costs to improve their applicability in properly selected cases. The FRP panel roofing provides a modest ROI and provides interior daylighting benefits in applications such as equipment maintenance sheds and workshops without climate control.
