For those of you not familiar with what causes the black streaks on asphalt shingles, algae is the culprit. The algae land on your roof and feed on the crushed limestone that is used in asphalt shingles. Rain then spreads the algae down the roof causing black streaks. This algae doesn’t allow the shingles to reflect heat properly and causes them to fail prematurely.

To remove the black streaks, find a reputable roof cleaning contractor in your area and make sure that they use the low pressure method. Having your roof properly cleaned will allow you to get the expected life out of your roof.
