What causes dark marks or black streaks on my roof?
Those dark marks or black streaks are Gloeocapsa magma. Depending on the age and condition of your roof, soft washing your roof is the best and most cost-effective solution. Roof replacement in comparison, which is not necessary most of the times, could cost up to 10 times more than roof cleaning.
The black streaks are not preventable as they are caused by humidity and is very common in Westchester, Putnam and Dutchess County, NY.. The marks are cause because of the algae
which survives through photosynthesis where the algae feeds on the limestone filler used in asphalt shingles.
Yes shingle makers have been treating roofs with copper or zinc to inhibit algae growth but these stop being effective over time. This leads to the algae eventually continue to eat the limestone in the shingles combined with the New York humidity and the dark marks or black streaks appear.
Most black streaks form on the northern side of roofs. This is because this where it’s darker and wetter which is perfect for algae to grow. Compared to Florida where it is even more humid, homeowners in Westchester County fare only slightly better.
Of course, in Arizona where it is more dry, there is less humidity so less algae growth.When the algae decays, the algae turn black. Therefore you see the black streaks on your roof.
Are the black streaks harmful to my roof?
Yes, the black streaks are harmful to your roof. This is because the black marks greatest threat to your roof is moisture retention or root damage that algae and other fungus and bacteria can cause. These two combine together to form lichen, the roots of which can wrap around and feed on the granules covering the shingles. Unlike black streaks, lichen is not easily removed.
Even when lichen dries, it comes right back after intense humidity, snow or rain, Scrubbing or power washing lichen will only cause more damage to your roof.
