Cool metal roofs are designed with coatings that feature proven reflective qualities, helping reduce roof surface temperatures compared to standard or uncoated roofing materials during periods of intense sunlight. To review the reflective performance of our available colors, explore the listings in the Cool Roof Rating Council (CRRC) database.
These advanced coatings enable cool roofs to maintain lower surface temperatures than conventional roofing options when sun exposure is highest. For additional details about color reflectivity, reference the CRRC website.
One of the biggest benefits of a cool metal roof is its contribution to sustainability, delivering lasting value through improved energy performance. Notable advantages include:
• Reduced Cooling Costs in Southern States: Learn more about savings using the Oak Ridge National Laboratories (ORNL) Cool Roof Savings Calculator.
• Lower Urban Heat Island Impact: Cool metal roofing can help decrease heat buildup in metropolitan areas. See Lawrence Berkeley National Laboratories (LBNL) Heat Island Group Website for more information.
• Energy Code Compliance: Cool roofing products are frequently included in energy standards and green building programs, with certifications tracked by organizations such as the CRRC.
Keep these important measurements in mind when evaluating the energy efficiency of metal roofing:
• Solar Reflectance: Measures the roof’s ability to reflect sunlight.
• Thermal Emissivity: Measures how effectively the roof releases absorbed heat.
• Solar Reflectance Index (SRI): A combined value that reflects overall thermal performance.
Choosing the appropriate color for your steel panels can significantly improve energy efficiency, as many finishes are engineered to reflect more solar radiation. Top-performing options include:
