Q: What are those black streaks on our roof?.

A: They’re a tough algae called Gloeocapsa magma. It tends to grow on the shadier north side of homes.

With today’s higher oil prices, shingle manufacturers have reduced the petroleum content and have replaced it with a record high percentage of limestone filler. 20¬†years ago, an asphalt shingle only contained 10 – 15% limestone filler. Today, that number is over 50%. Airborne algae LOVES to feed on limestone. The result is not only black streaks much sooner and greater, but also shingles that begin their life very dry and brittle with so much less petroleum in them. Metal roofing does not exhibit this algae streaking at all because steel doesn’t contain limestone.
