Roof Cleaning Warner Robins GA

Our cleaners at Propel Pressure Cleaning have years of experience cleaning roofs, so we can explain exactly what causes these black streaks on your roof and how to remove them. You’ll quickly see that our company offers the roof cleaning Warner Robins, GA residents trust.

What Causes Black Streaks?

Rather than dirt or mold, blacks streaks on asphalt shingle roofs are caused by the cyanobacteria Gloeocapsa magma, also called roof algae. Each streak is a colony of countless microorganisms that will grow as they feed on the limestone filler in your asphalt shingles. They’re common in humid areas like Warner Robins and are often found on trees and exposed rocks in addition to roofs.

Algae spores are spread by wind and animals, so it’s almost impossible to give your roof foolproof protection. They prefer dark and moist environments, so you are most likely to find black streaks on the north side of your house.

Why You Should Remove Streaks from Your Roof

While the effects of algae on your roof are only cosmetic at first, that’s reason enough to do something about the problem. Ugly black streaks will reduce your home’s curb appeal and, consequently, its value. A dirty roof can make potential buyers worry about needing to repair the roof in the future due to neglect.

If you leave the algae alone for long enough, they will start to cause structural damage to your roof. The dark layer that protects the algae from the sun makes your insulation less effective. It also holds in large amounts of moisture that will damage your shingles and make your roof a more hospitable climate for other molds and mosses.

Algae also eat away at the limestone in your asphalt shingles. In addition to wearing down their granules until your shingles break, the algae push their roots under and through roof tiles to loosen them.

Preventative Measures Against Algae

Roof algae are too common and easily spread to completely prevent, but you can take steps to inhibit their growth on your roof. Copper and zinc in galvanized sheet metal kill algae when they wash down your roof in the rain, so installing metal strips is an effective way to make black streaks less likely. You can also use asphalt shingles that have copper granules mixed in to make them resistant to algae.

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.
