A reflective roof coating is applied to roofs to help reflect more sunlight from the surface, thus reducing the amount of heat absorbed by the structure. Also known as cool roofing, these roof coatings are available in a number of colors, surfaces, and thicknesses and can make a huge difference when it comes to saving money on energy costs and usage. On top of that, they also aid in creating more comfortable indoor environments, and play a role in prolonging the life of roofs and roofing materials.
Cool roof coatings work to keep your home cool in two distinct ways. The first is by solar reflectance, or the coating’s ability to reflect sunlight away as soon as it hits your structure. Instead of absorbing the sunlight and heat like a traditional roof, a cool roof reflects the light and heat away from your home, keeping your home cooler in the process. The other way that cool roofing helps to keep your home cooler is through thermal emittance. These roof coatings are now made with special materials that increase your roof’s thermal emittance level, or your roof’s ability to radiate absorbed heat back into the atmosphere instead of down into your home. It’s this potent combination of high solar reflectance and thermal emittance that make these roof coatings so effective at keeping your home cool and your energy costs and usage down.
