Use Bleach

Chlorine bleach is the most common bleaching agent used to remove roof stains. The bleach is mixed with water three times its amount and a small volume of trisodium phosphate. The solution should be applied on the infected part of the roof via a sprayer. You should make sure not to harm surrounding plants by spraying water on them before and after the procedure. After spraying the stains, you should allow the area to dry and then re-inspect the stain. The process is repeated until the area is no longer sticky.

The products discourage the growth of mildew and preserve your roof for a long time. These products include zinc sprays, anti-growth sprays, and resistant shingles.
