Roof Algae 101: Dealing with Gloeocapsa Magma

When you look up at your roof and notice unsightly black streaks, there’s a good chance you’re seeing the effects of an all-too-common issue with the growth of Gloeocapsa Magma. Every year, more and more homes are affected by this algae-like bacteria, which shows up as black streaks on your roof. If left untreated, it could lead to expensive repairs. 

Luckily, homeowners can do something to protect their roofs and get rid of those ugly black streaks—and our team at A-1 Pressure Washing is ready to help with professional soft wash roof cleaning!

Silent Destroyers: Black Roof Algae Explained

Gloeocapsa Magma is a type of cyanobacteria, often referred to as algae, that thrives on the roofs of homes, particularly in humid and warm climates such as our down here in Southwest Florida. Unlike true algae, cyanobacteria are capable of photosynthesis and can produce their own food from sunlight, which is one of the reasons why it is so attracted to roofing material. This organism is naturally adept at clinging to surfaces like roof shingles and tiles, where it feeds on the limestone filler material used in the manufacturing of many roofing materials.

How Does It Affect Your Roof?

Those pesky, ugly black streaks on your roof aren’t just a cosmetic issue; they can also lead to damage. Here’s how they affect your roof:

  • It is just downright ugly: The most noticeable effect of Gloeocapsa Magmais the dark streaks it leaves on roofs. These streaks are actually colonies of the bacteria, which develop a dark, hard outer coating as a protective measure against UV rays. This pigmentation causes the blackening that’s commonly seen on affected roofs.

  • Eats away at your roof: Over time, the growth of these bacteria can lead to the breakdown of roofing materials. As Gloeocapsa Magma feeds on the calcium carbonate in limestone, it gradually degrades the integrity of shingles, leading to a shortened roof lifespan.

  • Energy bills go through the roof: A darker roof absorbs more heat, which can increase the temperature inside your home. This not only makes it less comfortable but can also lead to higher energy bills due to increased air conditioning use.

Before After

What Kills Gloeocapsa Magma?

If you’re looking to get rid of Gloeocapsa magma, you are not alone, we get asked everyday what kills Gloeocapsa Magma on roof? You may think roof pressure washing is the answer, but the most effective solution is a soft roof wash treatment. This method uses a low-pressure wash combined with special cleaners that are designed to safely kill the algae and its spores without harming your roof. 

The cleaners usually contain bleach or sodium hypochlorite, which break down the bacteria’s outer layer, effectively killing it and preventing its return. It’s important to use the right concentrations and to rinse the roof thoroughly afterward to protect your tiles and shingles. For the best results, consider hiring a professional roof cleaning service that understands how to properly mix and apply these solutions to ensure your roof is cleaned safely and effectively.

The Perfect Solution to Prevent Gloeocapsa Magma Growth

Managing and preventing the growth of Gloeocapsa Magma here in Florida involves regular maintenance. Fortunately for homeowners, Dan and Danielle at A-1 Pressure Washing & Roof Cleaning have the perfect solution to protect your roof. Our soft wash Roof Treatment is specially designed to safely remove Gloeocapsa Magma. This treatment uses a very low-pressure spray of an algaecide that not only clears roof streaks immediately but also kills moss and lichens. After the algaecide soaks in, the moss and lichens start to fade, break down, and eventually fall off as their roots naturally detach from the shingles.

Here are some effective strategies:

  1. Professional Roof Cleaning Services: Cleaning your roof every 2-3 years can help prevent the accumulation of Gloeocapsa Magma. It’s crucial to use the correct cleaning techniques to avoid damaging the roof. High-pressure washing can be harmful; instead, soft washing with appropriate cleaners and algaecides is recommended.

  2. Proper Roof Maintenance: Keeping your gutters clean and ensuring that your roof has proper drainage will minimize the damp conditions that favor the growth of cyanobacteria.

  3. Install Zinc or Copper Strips: Metal strips of zinc or copper installed at the peak of the roof can help reduce the growth of Gloeocapsa Magma. When rainwater washes over these metals, it creates an environment that inhibits the growth of the bacteria.
