Is That Algae, Moss, or Mold on Your Roof?

October 16, 2019

It’s quite the concern when homeowners look up and see what looks like black mold on their roof. Not only is it unsightly, but breathing in mold can be dangerous, too! The good news is that those ugly streaks on your roof are most likely not mold, but algae on your roof.

Algae and Moss vs Mold

Algae and moss are way more common roof problems homeowners face than mold. Both travel and spread through the air, thriving more in humid climates. If you see a next-door neighbor with moss or algae on their roof, it’s possible that it might show up on your roof, too! Unlike mold, algae and moss are not toxic or a major health risk to your family. They also won’t eat away at your roof as mold would. However, it’s still advisable to get your roof cleaned if you notice algae on your roof. In addition to curb appeal, getting your roof cleaned will also ensure water and debris don’t get stuck underneath any roof shingles, which could cause damage over time.

Mold, on the other hand, is a more serious matter. It doesn’t typically show up on the surface of your roof. Instead, it will usually grow in warm, damp areas that are poorly ventilated. Moss is not as common of a roof problem for homeowners as moss and algae but can be found in your basement, attic, or siding if they are improperly ventilated.  It can also show up on the areas of your roof that are not in direct sunlight or shaded by overhanging tree branches.

The Key to a Streak-Free Roof

So what’s the best way to keep algae, moss, or mold off your roof? Simply with regular roof cleanings! Prevention is vital to keep your roof in its best shape; when your roof is clear of debris and properly treated, you won’t have to spend time wondering whether you’re dealing with algae or mold.
