Roofs are your first line of defense against rain, wind, and snow. Over time, this can result in a buildup of algae, moss, or fungus, all of which are damaging to your roof. Unfortunately, rain will not get rid of these contaminants.
One thing that can take care of algae, moss, and fungus is a pressure wash with gentle pressure. But be careful here—gentle is important. Using pressure that is too intense can do serious damage to your roof, so this task is best left to a professional.
