Dallas Cool Roof Systems: Understanding Energy Efficient and Environment-Friendly Roofs Cool roof has been designed for reflecting more sunlight and absorbing less heat than a standard roof. Cool roofs can be made with a paint that is highly reflective, tiles, shingles or a sheet covering. Almost any type of building can get huge benefits from cool roofs, but it is still important to consider some important factors such as climate before installation. As compared to standard roofs reaching 150 degrees Fahrenheit more in summer, a cool roof under the same conditions stay 50 degrees Fahrenheit cooler, saving energy and money with the use of lesser air conditioning. Buildings and its occupants can greatly benefit from cool roofing systems through improvement of indoor comfort for spaces that aren’t air conditioned like covered patios or garages, reduction of energy bills because air conditioning needs are decreased, and decreased roof temperature, extending roof service life. Cool roofs are also environment friendly especially if there are many buildings in a community have them, reducing local air temperatures or urban heat island effect, lowering peak electricity demand that help prevent power outages, and reducing power plant emissions such as carbon dioxide, nitrous oxides, sulfur oxide and mercury through reducing energy used in buildings. Roofs come in different types, and the surface that is exposed to the sun determines if a roof is cool or not, but by choosing the appropriate surface of your roofing system is one way to make a new or existing roof cool. To make your roof cool, you can use white coatings or special reflective pigments that can help reflect sunlight, as well as very thick paints which serves as a protection against ultraviolet light and chemical damage, offering water protection and restorative features. Built-up roofs usually consist of a base sheet, reinforcement layers, fabric and a dark protective surface layer, and it can be made cool by substituting reflective gray slag for dark gravel or marble chips in a flood coat of asphalt, using factory-applied coating or reflective mineral granules instead of a dark coating, and applying a cool coating on top of the dark asphaltic emulsion coating. For making shingle roof cool, purchase cool asphalt shingles that use specially coated granules for better solar reflectance apply coating at the factory to make them more reflective. Usually, unpainted metal roofs are excellent solar reflectors but are poor thermal emitters, so to make them cooler, you can paint it to increase its thermal emittance and solar reflectance, and to achieve a cooler roof status.
