Ask the Leading Muncie Roofing Contractor: What is the Algae Danger Zone?

An experienced Muncie roofing contractor knows that your home is your largest financial asset, it’s the very structure that shelters your family, and one of your biggest sources of stress. As the crown of your home, your roof should not only perform to the highest standards, it should offer a welcoming, inviting look that complements your home’s aesthetic and adds to its curb appeal. But, if a tiny intruder named Gloeocapsa magma takes up residence at your address, look out! Your roof’s good looks and integrity may be in jeopardy.

Gloeocapsa magma is a cyanobacteria consisting of a small group of algae spores. Better known as blue-green algae, the spores create the dark and discoloring stains that form on roofs, appearing black as they grow and spread. These ugly stains are the bacteria themselves, in mass amounts, covering the roof shingle surfaces. This growth can affect your roof appearance, diminish its performance, and – worst case scenario – reduce its lifespan.

Where does algae growth usually occur?

For the most part, algae grows in places that offer the right temperature and humidity levels. While there are some “algae danger zones,” where conditions are just right, 3M has reported that algae is found on  over 80 percent of roofs in the country… essentially any locale with sufficient warmth and humidity.

How do you fight algae?

While some sources say that cleaning is a solution, the jury is still out as other sources claim that roof cleaning can actually cause further damage. The best solution is to speak with a knowledgeable Muncie roofing contractor about installing algae-resistant shingles. These shingles are manufactured with copper granules, known for their ability to protect against algae growth and infestation.
