My roof is fairly new at 7 years old with 50yr asphalt shingles. It's starting to get some moss on the shingles. Anyone have a recommendation for getting rid of this? I don't want to spray something that runs off and kills my plants on the ground. I also thought about using a pressure washer but don't want to damage the shingles.
