Roof System for Columbus commercial properties
Columbus commercial roofs with dark membrane surfaces reach 160°F in summer — heat that flows directly into the building and drives HVAC load. Cool roof systems — white TPO and PVC membranes, reflective EPDM coatings, and silicone restoration coatings with high Solar Reflectance Index values — reduce surface temperatures by 50 to 80 degrees and the cooling load that follows. We install and specify cool roof assemblies that
The term cool roof refers to any roofing system that reflects significantly more solar energy than a conventional dark-surfaced roof. Columbus commercial buildings with black EPDM or dark-surfaced BUR roofs routinely measure surface temperatures above 150°F on clear summer afternoons. The heat absorbed at the membrane surface conducts through the insulation layer and drives cooling load. A white TPO or PVC membrane on the same building will measure 80 to 100°F on the same afternoon — a 50 to 70-degree surface temperature difference that translates directly to reduced cooling demand.

System selection is checked against deck capacity, insulation needs, rooftop equipment, ponding patterns, wind exposure, repairability, and warranty requirements.
Owners receive a system-level recommendation that explains what can stay, what should be removed, where risk remains, and how the selected assembly should be maintained.
Questions
A Columbus commercial building converting from dark EPDM to white TPO can expect 5 to 15 percent reduction in annual cooling energy cost, with greater savings on buildings with high roof-to-floor area ratios (single-story buildings) and lower savings on multi-story buildings where the roof represents a small fraction of the envelope area. Buildings with below-code insulation see the most benefit. We can provide a rough energy calculation based on your building's square footage, floor count, and existing insulation R-value before you commit to a scope.
A cool roof designation does not provide hail damage resistance — membrane thickness and construction are what determine hail damage. White 60-mil TPO and 80-mil TPO provide the same resistance to hail impact regardless of their reflectance. That said, white reflective membranes tend to make hail damage more visible during post-storm inspection, which simplifies the damage documentation process for insurance claims.
White and tan 60-mil and 80-mil TPO from Carlisle, Firestone, GAF, and Johns Manville. White PVC from Sika Sarnafil, Fibertite, and GAF EverGuard. CRRC-rated silicone restoration coatings from Carlisle VersaFlex, GE Advanced Materials, and Polyglass for conversion projects over existing dark membranes. All products carry current CRRC ratings that we provide with the project documentation.
