Roof Damage in Shoreview

Have you noticed black streaks on your roof lately? If so, those black streaks that you see on your roof aren’t soot or mold, but are most likely caused by a type of algae called Gloecapsa Magma. Here in Minnesota, especially in the summer months, this type of algae isn’t uncommon, especially if you have asphalt shingles on your roof. Here is what to know about the black streaks on your roof and what you can do about them: Roof Damage in Shoreview Roof Damage in Shoreview

Roof Damage in Shoreview | What to Do About Black Streaks On Your Roof?

Whatever you do, don’t try and get rid of the streaks by spraying them with a pressure washer. Most likely all that will do is damage your shingles. Rather, you should hire a roofing contractor to gently spray on a solution made from trisodium phosphate (available at most hardware stores), bleach, and water to get rid of the black streaks on your roof.

Of course, cleaning your roof doesn’t keep the mold from reoccurring. You might have noticed how the shingles near metal, like around skylights or chimneys with copper flashing, aren’t affected by the algae. That’s because the water running off contains minute traces of metal that stops its growth. A similar solution can be created by installing copper or zinc strips under the full course of shingles at the ridge of the roof. As rainwater washes across the metal it will create an uninhabitable environment for future spores. Roof Damage in Shoreview
