Black streaking is the number one indicator that bacteria has begun to grow on your roof. If not treated quickly and properly, it can become a serious and expensive issue. But don’t lose hope. In this post, we’ll fill you in on how the streaks got there, how to remove them and how to keep them from coming back. And if you’re noticing moss, mold, or lichens, we’ll let you know how to handle that too.
How Do Black Streaks Get on Your Roof?
This streaking is evidence of an airborne bacteria that fall from nearby trees onto your shingles. The darker and more widespread it is, the more damage it’s doing to your roof. Since the sun rises in the east and sets in the west, the north side of your home gets the least amount of sun. The sun would normally kill these bacteria and dry the shingles, but without sunlight, a higher level of moisture creates the perfect breeding ground for these bacteria to spread.
These bacteria are called Gloeocapsa Magma. Technically a cyanobacteria, gloeocapsa magma is also a form of algae. It digs into and feeds off your shingles. Asphalt shingles are also made with limestone and ceramic. Over time, the bacteria eat away at the limestone in the shingles and loosens the granules. While it’s eating away at the roof, it continues to multiply.
It’s imperative to be proactive with your roof. Let’s look at a worst-case scenario: When Gloeocapsa Magma has taken residence on your roof for long enough, it will move into its next damaging stage. These bacteria will begin to work in tandem with natural fungus to create lichens on the roof.
Lichens and Moss on Your Roof
Lichens are slow-growing plants that form a crust like, leaflike, or branching growth on rocks, walls, trees, and untreated roofs. They are nourished by rain and moisture which will cause them to grow and spread. Lichens embed roots deep into bacterially prepared shingles. When they stake their claim on shingles for long enough, they pave the way for moss to grow.
Moss forms after lichens on the roof. Moss is far denser and more detrimental to the roof than lichens and Gloeocapsa Magma combined. Moss is heavier and more absorbent. It creates pockets of rainwater and moisture. As the water dams, it seeps into the shingles and underlying plywood. This creates a serious risk of causing structural damage. Once moss forms on an untreated roof, it eventually results in soil accumulation. This leads to grass and a host of other problems. At this point, replacing the roof will be the least of your problems.
While the evolution of Gloeocapsa Magma into a full-blown lawn on your roof takes a long time to come to fruition, you shouldn’t sit idly by as the black streaking gets worse. On average, it costs over $20,000 to replace a roof. We here at Perfect Power Wash can give you the preventative maintenance at a fraction of that cost.
Removing Gloeocapsa Magma, Lichens, and Moss
Our Perfect Roof Cleaning is tailor-made to eliminate Gloeocapsa Magma, algae, lichens, and moss. The process starts with a low-pressure application of algaecide to the affected areas of your roof. Black streaking will be removed immediately. If your roof is at the stage of moss and lichen growth, you have no need to worry. The moss and lichens are a much bigger threat and thus take longer to dissipate. Moss and lichens fall off over time as the roots release themselves.
Our Perfect Roof Cleaning uses a safe, low pressure to treat the roof. Using high pressure on the shingles causes irreversible damage. Shingles are fragile. High pressure damages the shingles and leaves a mess of debris all over your property.
Using the proper cleansers is vital. Our algaecide is designed for these infestations and defeats them in short order. It absorbs into the Gloeocapsa Magma, moss, and lichens where it gets to do its work from the inside. The moss and lichens will discolor, harden, and fall off over time while the Gloeocapsa Magma will disappear on the day of service.
Our in-field team members take great care of your roof while exhibiting unparalleled attention to detail. We examine the roof from all sides and utilize a low-pressure application of algaecide to ensure that every single problem area is reached. Everything is treated in sections using the safest practices in the industry. We are not happy with the work until you are happy, and the treatment is complete.
Will Black Streaks Return to Your Roof?
While our services absolutely remove these infestations, they are not gone forever. Like any exterior surface, contaminants find their way back over time. The best way to keep your roof protected is to treat it on an annual basis. By treating the roof once per year, you consistently restore the integrity of the roof and increase its lifespan. We offer a one-year warranty on the roof at no extra charge. If the treated areas grow back within a calendar year, we come back out and retreat it free of charge. The Perfect Roof Cleaning protects your property using a safe and proven process.
