Dallas Cool Roof Systems: Understanding Energy Efficient and Environment-Friendly Roofs

As compared to a standard roof, cool roofs have been designed for reflecting more sunlight and absorbing less heat. Cool roofs are usually made of highly reflective paint, highly reflective tiles, sheet covering or shingles. Any type of building can obtain benefit from cool roofs, but the climate and other important factors must be first considered before installation. When a cool roof is used it can stay 50 degrees Fahrenheit cooler under the summer sun, saving energy and money with the use of lesser air conditioning, while standard roofs can reach 150 degrees Fahrenheit more in the summer time.

Cool roofing systems benefit its occupants and the building structure through reduction of energy bills because air conditioning needs are decreased, improvement of indoor comfort for spaces that aren’t air conditioned like covered patios or garages, 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 create a cool roofing system, it helps using white coatings or special reflective pigments which can help reflect sunlight, or using very thick paints which can provide protection against ultra-violet light and chemical damage, offering water protection and restorative features.

To make the surface layer of built-up roofs cooler, you can replace reflective gray slag for dark gravel or marble chips in a flood coating of asphalt, utilize factory-applied coating or reflective mineral granules rather than using a dark coating, and application of cool coating on top of the dark asphaltic emulsion coating directly. 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. Metal roofs can be made cool by painting it to increase its thermal emittance and solar reflectance, and to achieve a cooler roof status.
