You can see those ugly black streaks on roofs almost everywhere. Algae is a problem in most of the country, especially in hot, humid climates, and once it takes hold, it’s hard to get rid of, so prevention is the goal.
Quick! Look up at your roof! Is it dirty,
streaky, stained, and downright ugly? If you answered yes to any of the above,
then chances are your home is being attacked by algae - a living organism
growing on what was once likely a beautiful roof.
