Gloeocapsa magma (GM) is the black stains you may see on your roof. The black stains are buildups of the algae that can prevent the sun from burning off the bacteria. GM algae feed off of the roof’s asphalt and limestone causing irreversible damage to your shingles. Another roof pest is the roof lichen. Lichen colonies can be quite damaging to shingles. Their penetrating tentacles create ugly marks where they grow and eventually ruin the shingles as well.
Then there is mold. Mold is perhaps the most detrimental thing that can happen to a roof. When moisture is trapped in your roofing system it will develop mold. Standing water and humidity, paired with growing algae spores, can be a breeding ground for harmful mold. Mold can pose serious health risks to you and your family.
We use the latest soft wash equipment and techniques to safely remove algae, mold mildew, lichens, and gloeocapsa magma without damaging roof shingles.
