Here in the Pacific Northwest, roofs deal with constant moisture, shade, and organic debris — the perfect environment for unwanted growth. But many homeowners don’t realize there’s a big difference between moss and algae on a roof. They may look similar from the street, but the impact they have on your home (and your warranty) is completely different. Understanding the difference helps you protect your home and make the best decision when it’s time for roof cleaning, maintenance, or replacement.
