Someone mentioned copper, that may work also, but our new shingles have Zinc in them and have no mold, mildew or algae in 8 years.
Check with a pressure washing company and see if they do roofs and what does it take to clean it off and not damage the roof.

I can't answer this but was wondering if these solutions would help keep algae off of vinyl siding also. I have to wash one side of my house every year because of algae and it is in the sun too, but on the back side of house.
