The Asphalt Roofing Manufacturers Association (ARMA) has produced a new short, step-by-step animated video about roof algae for homeowners and building owners alike.
Roofing contractors know what a magnet roofs can be for the random debris of society — and it often gets to ferment for several months before anyone notices.
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.

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.
