Gloeocapsa magma is ubiquitous on roofs in Brownsburg-Chatham. Transported by wind and birds, it colonizes shingles and protects itself in a dark gelatinous sheath — hence the characteristic black streaks. It feeds on calcium carbonate granules embedded in your shingles. Sodium hypochlorite (SH) is the only recognized product to penetrate this sheath and destroy the organism.
