Aluminum roof coatings can reflect up to 80% of ultraviolet rays, which will prevent sunlight from compromising your roofing system as quickly. Over time, roofing systems will naturally sustain damage due to prolonged exposure to sunlight, but aluminum roof coatings from Atlanta roofing companies stop that dead in its tracks. Plus, by deflecting sunlight away from the roof, aluminum coatings will also keep the interior of your home cool. Improving your home insulation will inherently improve comfort and decrease energy costs.
