Gloeocapsa Magma Brief History
Asphalt roofs across much of the much United States are being infested by a dark green algae (commonly considered black mold). The technical term for the algae is Gloeocapsa Magma.
Gloeocapsa Magma Algae is spread by wind and animals, and grows from a dot to a spot to a streak. As a Gloeocapsa Magma Algae colony grows, older algae decompose, and will hold moisture, which enables the entire colony to grow even more rapidly. Many times a homeowner will just notice a spot, and in no time, half the asphalt roof shingles are covered. Increased moisture levels lead to the growth of lichen, mold and even moss. When lichen are present a phycobiont relationship exists between the Gloeocapsa magma (provides the photosynthesis algal component) and the lichen (the fungal portion of the colony).
Luckily, the Gloeocapsa Magma Algae can be removed by thorough roof cleaning by the only SoftWash authorized roof cleaning company in West Michigan – Roof Cleaner. 616-240-3465
