I have a wooden shed like all my neighbors, however, on one side of the roof there is a green alge growing. What is the best product out there that I might get?

By the way, none of the neighbors have alge on their roofs. Weird Huh?

That roof may be shaded or angled away from the sun.
Try a 1/3 bleach-to-water mixture in a pump-up sprayer, spray it on, allow to soak for about 15-20 minutes, and hose it off.
Do it again, if it doesn't quite get it all the first time.
Cover any drip line vegetation with plastic before spraying or rinsing.
Good Luck!
