Does Spraying Water On Roof Cool House? [Solved]
Heat naturally flows from warmer areas to cooler ones, so in order to cool down your home, you need to create a temperature difference between the inside and outside. This is where spraying water on your roof comes into play. As water evaporates from your roof''s surface, it absorbs heat energy from the surrounding air and cools down the area around it.
