Central Ohio's humid summers, frequent rain, and shaded neighborhoods create the perfect environment for organic growth on roofs. If you live in Dublin, Westerville, Powell, New Albany, Upper Arlington, Worthington, or anywhere in the Columbus metro, chances are your roof is dealing with one of these four common problems:
Caused by Gloeocapsa Magma algae feeding on limestone in your shingles
Thick, sponge-like growth that lifts shingles and traps moisture underneath
Crusty, gray-green patches that secrete acids eating through your granules
Dark, slimy spots in shaded areas signaling persistent moisture problems
