Roof-Techs F.A.Q.s

This problem infects 70 percent of homes in humid areas of the United States. (Welcome to Virginia) It is an alga called Gloeocapsa Magma which is actually a dark blue in color.
Gloeocapsa Magma is a species of algae that causes dark streaking discoloration on asphalt/fiberglass shingles. The dark staining you see on many roofs is caused by the growth of algae and fungus spoors that land on the roof and is normally noticed on the north side of the house first.
Trees do not have to be present for this air born menace to set up home on your roof. This alga produces its own energy source and feeds on inorganic materials, such as dirt on the roof and the materials in shingles.
Many home owners say that they never had a streaking problem with their old shinglesRoof shingles have changed in the past 25-30 years. They were made of a true asphalt impregnated felt. These asphalt shingles were heavy and stable. With the source of felt based materials dwindling and rising petroleum prices, the shingle manufacturers switched to a durable fiberglass backing. This was a longer lasting product that needed a little more weight added. So they introduced finely ground limestone to help fill the shingle composition.
Sounds good enough, but most limestone is an inorganic compound which Gloeocapsa Magma will thrive on. There are anti-algae shingles on the market today, at a bit more of the cost.
An estimated 50% of roofs are replaced due to appearance of the roof and not the functionality.
Most roofs still have many years of life, but these algae will shorten that if not cleaned or treated. The fungus holds moisture and can break down the fiber or loosen the granules on the shingle.
