Clean Algae from Asphalt Roof: How to Remove Those Stubborn Algae or Moss Stains from Your Asphalt Roof

Submitted By

My roof is 6 years old. I discovered some nasty black staining that I believe is a moss or algae. Can you suggest a product to get rid of this and prevent it from returning on my roof? I would like to do this myself, and was wondering if this is a do-it-yourself project, or do I have to hire someone to clean my roof?
