If you have to paint the roof of your school or home white, what would happen?

Correct Answer

If the roof is painted white, it will reflect the Sun's heat instead of absorbing it.

This will keep the rooms below cooler and more comfortable, especially during hot weather. It helps reduce the need for fans and air conditioning, saving electricity.
