A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm. A white object reflects all wavelengths of light, so the light is not converted into heat and the temperature of the object does not increase noticeably.
Not only do white roofs reflect more light, but they lose the energy they do absorb more quicklyâa principle known as thermal emittance. On a hot day, a standard black roof can be 100 degrees warmer than the ambient air temperature, while a cool roof might be only 20 degrees warmer.
