Exterior Cleaning Professionals of Austin Inform Locals About The Black Streaks on Their Rooftops
Austin, United States - June 22, 2023 / Pressure Washing Marketing Pros /
Asphalt roofing materials have a proclivity for developing unsightly black streaks. Austin’s residents want to know what they are and how to eliminate them. As experts in roof cleaning in Austin, TX, Activate Pressure Washing’s team members provide answers.

How Algae Develops on Rooftops
Gloeocapsa magma, a common type of algae, is often the culprit for black streaks on rooftops. As the spores collect in concentrated areas of a roof, they facilitate bacterial growth. Although the growth appears black to the average person, its true colors range between blue and green.
The bacteria flourish in hot, humid environments. Surfaces that don’t get daily sunlight provide a safe haven for colonies of organisms. Thus, most buildings develop algae on their northernmost sides.
The algae prefer asphalt roofing material due to its reflective qualities. Most asphalt shingles come in lighter colors and can retain moisture more readily than other materials. This allows algae to flourish.
Can Algae Harm Roof Materials?
While this algae won’t immediately harm a roof, it does age the building’s appearance. The property looks older and unkempt. Eventually, it might affect how well the asphalt shingles work to keep moisture out of the building.
Algae retain moisture. As it grows undisturbed on a rooftop, the moisture penetrates deeper and deeper into the shingles. This may lead to structural rot characterized by buckling or warping later on.
Professional roof cleaning in Austin, TX is the best way to remedy the issue.
Eliminating Algal Growth from Rooftops
To achieve a clean roof, property owners should seek services from professional roof cleaners in their areas. An inexperienced person will struggle to handle a pressure washer at such heights. Rooftop work presents dangers to unskilled operators.
Additionally, general machine operation can result in myriad injuries according to the CDC. Therefore, only experienced service providers equipped with suitable cleaning solutions and tools should tackle the task.
Preventing Algae from Growing Again
Although pressure washing services will eliminate current colonies of bacteria and algae, these organisms can reestablish themselves on any building after time passes. How can property owners prevent algae from becoming a recurring issue?
Installing Other Materials
When property owners need to replace their roofs, they can look into materials that don’t facilitate algal growth as readily. Metals like copper and zinc are hostile to organic growth.
Taking Preventative Measures
Property owners seeking a less expensive solution can occasionally do the following:
- Inspect the roof.
- Remove debris that bacteria could consume.
- Purchase gutter cleaning services.
These actions eliminate resources that facilitate algal growth.
