Black Staining on the Roof (Question)

Hey Al,

We live in a twenty-year-old ranch, with a two-year-old roof. We had the new roof done in a light colored shingle.

Now we have noticed black staining starting near the peak and running towards the edge. Our house faces south, but the stains are on both sides of the roof. We are not close to trees, so we cannot figure out what is causing these stains.

Can you tell us what these stains are and how to get rid of them?

Tony
