Moss on roofs starts with the spores which find a surface, moisture and organic material which tends to gather on the edges of the shingles to feed on. Similar to Mold, the spores are always in the air, looking for a good place to land and grow. Once established on the organic layer on the roof, the organism will put down roots into the asphalt shingles where they will then feed on the oils in the shingle. It is for that reason that you should never pressure wash, scrape or broom off moss from a roof...ripping those roots out exposes weak points in the shingle's granular protective top layer. This leads to premature wear and replacement.

Is it a good idea to paint roofs with special paint to stop moss growth?
As far as I know there is not paint that "stops moss growth" The problem needs to be fixed by killing the sources of the growth of mildew and moss. Perhaps it is a moisture problem. You need to kill the moss first then paint it with a special coating. I called Sherwin Williams and they helped me out tremendously. Just make sure you tell them if you have a pitched roof or a not. It makes a difference.
