Black Mold On Roofing Shingles

I am really disappointed the treated shingles didn t work.

Black mold on roofing shingles.

In reality what you are seeing is not black mold but a bacteria that is called gloeocapsa magma. These stains will discolor your roof and damage the shingles over a period of time if left alone. There are a number of commercial products available that will get rid of mold but if you don t mind working at heights getting mold off roof shingles is really something you can. The black mold like stains and streaks that appear on roofs particularly light colored asphalt shingles is actually a blue green algae gloeocapsa magma.

Not only is it unattractive it can actually shorten the life of your shingles so you really should get rid of it. Extensive mold growth can also expose the interior of your attic or crawlspace to mold spores carrying the problem over to the inside not to worry though because you can clean the mold off with basic household bleach and save. The black streaks are also known as black algae or roof mold. Granted some of it could be mold but what is spreading like wildfire is gleocapsa magma.

I covered our asphalt shingle roof about five years ago with white 50 year guaranteed shingles that had algae prevention treatment but now the entire north side of our roof is black with algae i bought the shingles from lowe s in marianna florida. Mold or mildew makes black ugly streaks on a roof. Mold stains can form on roof shingles that are in permanent shade. Those that tend to be the most humid furthermore they will only appear on the north side of the roof.

Commonly found in climates with warm humid summers it does no damage to the roofing but it certainly does looks bad. You clean it and it returns year after year.
