Alamo Roofing: Do Your Shingles Have Black Stains and Streaks

Have you seen any black stains on your Alamo roofing shingles? A well-maintained property doesn’t help when the roof shingles have black streaks on them. In today’s blog, we’ll discuss what those unsightly stains are and how to get rid of them.


What Exactly Is It?

Mold or mildew development on shingles can occasionally generate streaks, however, this is not always the case. Roof specialists believe that black streaks are generated by algae called gloeocapsa magma. Airborne spores drop it on your roof, where it consumes the limestone filler in your tiles and absorbs lots of sunlight for photosynthesis. As the algae are active, it is blue-green, but when it dies and begins to degrade, it turns black.

 

Some shingles are treated with copper or zinc to inhibit algae development, but their efficacy wears off with time. The streaks not only detract from the curb attractiveness of your property but also trap moisture and offer breeding sites for fungus and moss. Fungus impairs shingles and is incredibly tough to get rid of.

 

Algae-caused black streaks are especially common in humid parts of the nation. Roofs that receive less sunshine exposure are more prone to remain damp and foster algae growth.
