General question regarding asphalt shingles. Why does algea form on shingles when there is adequate sunlight. I can understand if a house has alot of tree cover, but why would it form on a house with mostly sun? And what is it that it lives on for food that would be in shingles or a mostly dry roof? I’ve used the 50 yr. shingles on a few jobs with the “algae eater”, but haven’t been there long enough to see if they really do. Thoughts/comments?

It's particularly bad around a golf course. I don't know if it might be the constant moisture from sprinklers, or maybe the fertilizers and sprays.
