    Bleach and water in a pressure washer but be careful because it will slime up and be slippery.

    a good pressure washer will get rid of it, havent heard of anything to prevent it ( if you walk the roof watch out that stuff is slick)

    Prevention after moss is gone. Algae resistan shingles great but if current shingles are good go to aroofing store and ask for a zinc strip. Just put one on my barn.

    copper, zinc or iron strip on the top of your roof. I do many and spray ferrous sulfide to kill the moss every spring and then mid summer get up on top and use a flat shovel and scrape it off. draws about 200 for 25-35 min of spraying and 20 worth of fe. and then another 150 for scraping. after the scrapping I offer yearly spraying of fe. Works very good.
    very profitable.

    If it's wood shingles, pressure washing may be one of the most damaging things to do to the roof.

    That moss-kill stuff that comes in 1 gallon jugs for roofs is great. Just don't overspray onto the landscape plants.

    It takes a few weeks to do the job - slow kill.

    The zinc strips mentioned earlier, are very good too.
