A roof's primary function in a building is to protect occupants from the weather, however rooftops are increasingly acting as a substantial source of excess heat. As a result, Cool Roofs are being used more widely because they address the issue of excessive heat transfer through roofs, which account for about 40% of a building's surface. In comparison to conventional roofs, it reflects sunshine and absorbs considerably less heat.
Additionally helpful in minimising the impact of the urban heat island are Cool Roofs. An urban heat island is a city that has been made hotter by human activity than the cool area around it. Increased energy demand, more greenhouse gas emissions, and a decline in the standard of living are all results of this effect. One of the most important green technologies nowadays is cool roofing. Compared to regular roofs, cool roofs are made to absorb less heat and reflect more sunshine.
