Many homeowners make the mistake of thinking their roof is dirty, which leads them to believe that a pressure washing will wash away the dirt. The truth is, your roof isn't dirty at all, it's actually covered in algae and mold growth that comes with the territory when owning a home, running a business, or managing a property in the hot and humid climate of South Louisiana.
