    Default Alge, shingles

    I have a section of my roof that has something on it that may be alge. It is over the bathroom. Is there anything I can apply to the shingles to get rid of the alge? There are asphalt shingles on the roof.

    Yes, get on top of the roof on a day when no rain is perdicted, and spray 100% bleach (don't add water) using a hand held garden pump sprayer. In 20 minutes the green stuff will start disappearing. For stubborn areas, apply again.

    Safety goes without saying.
