Why Does My Asphalt Shingle Roof Have Black Streaks On It?

Primordial Ooze

That black wet mold growing on your shingles and other parts of your roof isn’t actually mold. It is one of the oldest species of bacteria on Earth. Think back to those high school biology videos of dinosaurs and such and the water showing lots of black ooze. Well, that ooze still exits and apparently it is growing on your roof. Gloeocapsa Magma resembles algae but is actually a bacterium that grows in damp and wet areas. It will continue to grow, and a bitter winter won’t kill it. So, if you are looking at a slick black linear growth on your roof, it won’t get better. It will only grow in size.

Is Gloeocapsa Magma Harmful?

Gloeocapsa Magma is harmful to your roof. You should be careful to get rid of it as soon as it starts to grow. Each season you let it alone, the larger it gets and the more damage it produces to your roof and shingles. How does it injure the roof? Gloeocapsa Magma absorbs water and latches onto the grains of the roofing panels. Water leads to rot and mold. This will absolutely harm the shingles and the wood underneath the shingles. As far as the grains, as anything latches on, it pulls the grains apart and damages the shingles. So, combining the damage of water and damage of fibers, your roof will lose years in its life if it is left alone.

How Do I Get Rid Of Gloeocapsa Magma?

If you want to get rid of Gloeocapsa Magma then you need to hire a professional that can properly clean your roof with brushes, sprays, or chemicals, depending on the state of the bacteria. This isn’t a simple job and don’t expect to do it by yourself in a morning. You may not even get it all. Instead you may only slow the spread instead of eradicating the spread.
