You may have noticed some stains on your roof. These stains can appear in a number of forms and can be caused by a number of underlying issues. So, here is some helpful information to help you identify stains on your roof and their root cause:

  • Black streaks on your asphalt shingles are one of the most common types of roofing stains. These streaks actually come from a form of algae that can grow on asphalt shingles.  If you notice these streaks, have a professional clean your shingles as many cleaning products can actually deteriorate your shingles. 
  • Reddish-orange stains or streaks are likely from some area of rusting metal on your roof, most likely your chimney flashing.
  • If you see a dark brown or black stain in certain areas of your roof, especially under nearby trees, rotting leaves and yard debris could be the issue. Be sure to keep your yard’s landscaping trimmed and to clean your roof of yard debris a few times a year.
  • If you notice any green mold or algae growth on your roof, this is usually caused by excess moisture, which could be coming from a roof leak. Be sure to call a roofing professional to have this issue addressed.
