How does whitewashing roofs help the environment?



  1. 0 Votes

    Whitewashing your roof helps reflect heat from the sun. This way, your home will keep cool in hotter temperatures, and you will be able to use less (or none) of your AC system. One study calculated that if all the rooftops and paved surfaces in the world’s major cities were painted white, the global cooling effect would be enough to delay climate change by about 11 years.
