Black stains running down your shingles? You might be wondering what that is or if it can damage your roof, and the answer might surprise you. Those black streaks are actually an algae called Gloeocapsa magma. As the blue-green algae accumulate, they develop a dark, hardened outer coating, which results in the black stains you see. Aside form being unsightly, the algae feed on the limestone and overtime will eat away at that limestone and other fibers that make up your shingles. This can cause an unexpected bill requiring you to replace your shingles well before the time to do so normally arrives. In fact, having a professional clean your roof once every year or two can extend the life of your roof by 10 to 20 years!
