What Are Those Black Streaks On My Roof?

Gloeocapsa Magma: Explaining Roof Streaks

Every year, more and more homes are infested with an algae-like bacteria called Gloeocapsa Magma. This infestation presents itself as black streaking on your shingles and can lead to costly repairs if left untreated. Luckily, there is something that homeowners can do to protect their shingles and remove roof streaks— and the team at Platinum Pressure Washing is here to help.

One thing about Gloeocapsa magma is that you have probably seen it (black streaks) on your neighbors’ roofs, as well as your own, indicating that the bacteria can travel in search of a comfortable breeding ground. As it spreads, Gloeocapsa magma eats away at the limestone filler in your shingles, causing damage and ugly streaking. First appearing on the north side of your roof, this algae spreads rapidly if not promptly addressed.

One effective solution is to contact a professional to provide what is known as a “soft wash roof treatment”. This service utilizes a soft wash method using specially formulated algaecides to safely eradicate the infestation at its source. However, when choosing the right company for the job, be sure to do your research and select a reputable business with the experience to safely provide great results— such as Platinum Pressure Washing.

Airborne Roof-Killing Algae

Algae thrives in moist conditions, like your shingles, and feeds on the organic material found inside them. As the algae eats away at the limestone filler, it leaves behind black streaking to shelter itself from sun exposure. That is why you are seeing these roof streaks.

By eating the limestone on the shingles, Gloeocapsa Magma compromises the integrity of your roof, shortening its lifespan. Since the roof is darker it is also less reflective. This makes the home hotter inside and more energy is required to cool it. Worse yet, ugly algae stains lower the perceived value of a home, reducing curb appeal and pride as a homeowner. The best thing to do with algae is to eliminate it as soon as possible.

The Perfect Solution

Our soft wash roof treatment is designed specifically to remove Gloeocapsa Magma in the safest possible manner. The Roof Treatment utilizes an extremely low-pressure application of an algaecide that not only removes roof streaks on contact but also neutralizes moss and lichens. Once the algaecide saturates the moss and lichens, they will begin to discolor, break down, and will fall off over time as the roots naturally release themselves from the shingles.

After our soft wash roof treatment, your roof will look brand new! Call us today at 502-472-1659 for your free estimate!
