Asphalt, tile or metal roofs are not immune to this invasive pest that appears to be dark stains creeping up a roof. Gloeocapsa magma is a species of cyanobacteria. Cyanobacteria are an ancient line of photosynthesizing bacteria, which photolyze water generating oxygen gas. Ancient cyanobacteria were ancestral to the chloroplasts of all plants on earth. We live in nature and nature keeps trying to take back over – look up sometime and you will see the visual evidence. This bacteria grows like an algae on your roof, it feeds off of moisture and some calcium from those asphalt shingles. Then, moss and lichen feed off the algae, creating a nice little forest bed on your roof. Well, it isn’t that nice, not really.
