Unwanted growth on your roof can spread before you know it. Whether it’s moss, mildew or fungus growing up there, you should do your best to get rid of it as soon as you notice it because it will only continue to spread if left unchecked. Bleach solutions are safe for non-asphalt roofing and easy to use. You should use a non-bleach solution if you have asphalt roofing.

  1. Spray any plants near your roof you want to protect with clean water before and after bleaching your roof.
  2. Soak the offending growth with a solution and leave to sit for at least five minutes.
  3. Rinse away the growth with a low-pressure stream of water.
  4. Leave the roof to dry completely before applying additional treatments until all growth is removed.



Great report, I was able to just forward it to my contractor so they knew exactly what needed to be done.
