Cool roof coating is a white or light coating with high solar reflectance and high thermal emittance. In plain terms, it bounces most of the sun back and sheds the heat it does absorb. A dark roof in Milwaukee, WI on a summer afternoon can get far hotter than the air around it. A cool roof stays much closer to air temperature.
Some states and cities have cool roof rules for commercial reroofing, California's Title 24 being the best known. Many utility programs also offer rebates for cool roof products. We will use rated products and help you gather the product data your permit or rebate paperwork asks for.
Almost any coating we install can be a cool roof coating if it is rated for it: silicone, acrylic and many urethane top coats. Keeping it cool means keeping it clean, because dirt and biological growth lower reflectance over time. We can set you up with a simple washing schedule.
Cool roof coating in Milwaukee, WI pairs well with spray foam roofing on buildings that need more insulation too. How much it helps your energy bills depends on the building, so we do not promise a number. Call (833) 441-4944.
