Roof Cleaning Warner Robins GA

What Causes Black Streaks on My Roof?

So, what causes those black streaks on your roof? An algae called gloeocapsa magma. While gloeocapsa magma is generally a green or blue color, it darkens to protect the algae from UV rays when it groups.

This type of algae can also appear black on certain surfaces, such as your roof. Gloeocapsa magma grows in a distinctive streaking pattern in warm, humid, and dark areas.

You can most often find gloeocapsa magma on asphalt shingles. This roofing material contains fragments of limestone and fiberglass that encourage algae growth and provide a food source.

Are the Black Streaks Dangerous?

Generally, gloeocapsa magma is not dangerous. However, it can begin to compromise the integrity of your shingles after an extended period of time.

The longer algae stays on your roof, the harder it is to clean. Power washing your roof eliminates the algae before it becomes challenging to remove. That’s why regular roof cleaning in Warner Robins, GA keeps your house safe and looking its finest.

How Do I Remove Black Streaks from My Roof?

Cleaning black streaks requires more than just chlorine bleach and a garden hose. To remove black streaks safely and completely, hiring a professional power washing company is the simplest solution. Roof cleaning companies know the best cleaning products to use and the most effective roof cleaning methods.

Roof cleaning companies also have the knowledge and experience to reach hard-to-reach places. They safely and expertly work with pressure washers and on wet, slippery roofs. Hiring a professional for regular roof cleaning is an easy way to prevent the black streaks from regrowing.

We are so pleased, he made our house look brand new once again! He took special care not to dislodge our new mulch and got all of the mildew off of our siding and windowsills. We will definitely be calling him again when we need honest, fast pressure washing.

I recently contacted several pressure washing companies in my area and did some price comparisons. Propel Pressure Cleaning Company gave me a reasonable estimate & that’s exactly what I paid! The service time was prompt, and I was very satisfied with how clean my house was upon completion. I highly recommend this company & I’ll be using this company for my future pressure washing needs.

Jesse was very quick to return my messages, and they were able to fit me into their schedule very quickly. They even came out to do the work while it was raining, so they’re pretty dedicated to getting the job done. I’d call them again in the future.
