My shop is 14 x 20 with an asphalt shingle roof. The back side doesn't get much sun (most covered with pine trees and pine needles), so I am fighting the battle of moss on the roof. I have fought this battle for going on 4 years (since I bought the house). I have tried everything short of putting a new roof on. Tonight I spent about an hour on the roof using a rubber scrub broom, something you might use cleaning your pool. This weekend I will spray the roof down with Round-up and it will be ok for a few weeks. I know that a new roof would resist this kind of thing for a while, but I don't have that kind of money right now.
An uncle of mine told me to strap a cooper wire near the top of the roof. This would react with ran water and prevent mildew and moss from growing on the roof. Anyone else ever heard of this, or have any other ideas?
