Monday, May 1, 2023


The HOT Texas summer is almost here and it’s likely that our Texas weather has caused unsightly black stains and streaks on your roof. It is important to address the root of this issue, which is the bacteria, mold, mildew and incredibly destructive Gleocapsa Magma that causes these stains. We have outlined the top 3 things you need to know about Gleocapsa Magma and why its so important to keep your roof rid of this harmful contaminant: 



  1. What is Gloeocapsa Magma?


Gloeocapsa Magma or “Black Algae” is a bacteria that not only causes the black stains you may see on your roof but also causes the shingles on your roof to break down by feeding off the limestone granules that are embedded in the shingles. The black stains are actually buildups of the algae that can prevent the sun from burning off the bacteria, which ends up causing your roof’s ability to reflect ultra-violet rays of light to decrease, shortening the lifespan of your roof.


  1. Can SoftWashing Destroy Gloeocapsa Magma?


Yes. SoftWashing can destroy Gloeocapsa Magma in that it uses safe chemicals to aid in the break-down of Gloeocapsa Magma and other infestations so they can be easily washed away. The products used in the SoftWash System don't just clean -- they penetrate, sterilize and eliminate the root of the problem, while inhibiting future growth of not only Gloeocapsa Magma, but also mold, lichen, mildew, moss, and other environmental contaminants.


  1. Does Gloeocapsa Magma Shorten The Lifespan Of Your Roof?


In addition to being a harmful bacteria that builds up on shingles and causes your roof’s ability to reflect the sun’s ultra-violet rays, Gloeocapsa Magma holds moisture within the shingles causing premature aging, rotting and/or granule loss. Gloeocapsa Magma algae feed off both asphalt and limestone causing irreversible damage to your shingles. This means that your roof will likely need to be replaced sooner than its anticipated lifespan, costing the property owner thousands of dollars.


In addition to shortening the lifespan of your roof, Gloeocapsa Magma on residential properties can lead to lower property and lower resale values. In addition, homeowner’s insurance companies are cancelling policies due the damage that Gloeocaspa Magma is known to cause.

Gloeocapsa Magma can also be the culprit of create higher utility bills as it reduces your roof’s ability to reflect the sun due to a buildup of Gloeocapsa Magma on its shingles and a black, stained roofing draws in more heat, causing increased utility costs.
