Remove Moss from a Shingled Roof
There are two methods to keep the moss away:
1. Sprinkle the affected areas with a laundry detergent containing bleach granules.
2. Buy a roll of 4” zinc. Measure the roof ridge and cut a strip to match. Insert the strip under the ridge shingles on both sides so that 3” is showing. The oxidizing process of the zinc will continually coat the roof below and prevent moss from growing.
