![]() The paint reflects the sunlight, keeping the house cooler than can a traditional roof, which absorbs the sunlight instead. How it WorksĬool roofs are created by using cool roof coatings, which are thick, white or reflective paint applied to the roof, it covers or shingles to protect the roof from UV light, chemical and water damage, maintaining and restoring the roof itself, making it last longer than traditional roofs. The introduction of cool roofs, though a seemingly insignificant change, would not only help people in developing nations but those in developed countries as well. Americans alone consume the same amount of electricity for air conditioning as the total electricity used for all the needs of 1.1 billion people in Africa. The energy demand from developing countries is predicted to climb more than 33-fold by 2100. ![]() Another 2.3 billion can only afford inefficient, unhealthy air conditioning models that use HFC gases that are thousands of times more polluting than carbon dioxide. Over 1 billion people in developing countries face significant risks from extreme heat, with no access to electricity for cooling. The world will benefit financially, environmentally and even comfort-wise from the addition of cool roofs. This cooling technology naturally cools the house, while being cheaper and more energy-efficient than traditional roofs, prompting many parts of the world to consider shifting towards them. ![]() First researched in the 1980s, cool roofs only became a reality around 2001.
