Preventing and Removing Algae from Asphalt Roofs

One of the problems you can face with asphalt shingles is the formation of dark stains or streaks on your roof. These dark patches are actually caused by algae. The good news is that these algae stains are not damaging to your roof; they are, however, unsightly. So what can you do to remove them – or better yet to prevent them from happening in the first place?

This question is answered quite well in an article posted by Danny Lipford atToday’s Homeowner entitled How to Remove and Prevent Black Algae Stains on Asphalt Shingle Roofs. In this article, Danny Lipford gives some useful tips including:

  • During your next roof replacement, ask for algae resistant shingles. These shingles have copper mixed into the asphalt, which prevents the growth of algae.
  • Algae stains can be chemically cleaned off your roof, but they will most likely return. Keep in mind that repetitive cleaning can be damaging to your shingles.
  • You can create your own algae cleaner using bleach and a heavy-duty cleaner such as Oxy Clean.
  • Always use extreme caution when cleaning your roof. This includes wearing slip-resistant shoes, eye protection and a safety rope where needed.
  • Be sure to wet down any grass or plants that are near where you will be working to protect them from the chemicals that will run off the roof. You can cover bushes with plastic after wetting down to provide added protection.
  • Once the roof is clean, you can prevent the regrowth of algae by installing a copper or zinc strip on each side of your roof just below the ridge.
