Black streaks on your roof are more than just an eyesore. They are often caused by a type of algae called gloeocapsa magma, which thrives in warm, humid climates and feeds on the limestone filler in shingles. Left untreated, these streaks can darken and spread, leading to premature roof aging and decreased curb appeal. Our team of Atlanta roof cleaning specialists understands how frustrating this problem can be, and we take a safe, effective approach to restoring your roof’s clean look without causing damage.
Gloeocapsa magma is a type of blue-green algae that commonly appears as dark, streaky stains on asphalt shingles. These streaks spread over time because the algae spores are carried by wind, birds, and rain. Aside from looking unsightly, the algae can trap moisture on the surface of your roof and weaken its protective granules. This can shorten the lifespan of your shingles and lead to costly repairs.
Some homeowners assume black streaks are just cosmetic, but they can be a sign of bigger problems. Trapped moisture may encourage moss and lichen growth, which can cause shingle lifting. Over time, this can create entry points for leaks and water damage inside your home. Professional roof cleaning is the safest way to address this issue before it worsens. Not only does it restore the appearance of your roof, but it also helps protect the structural integrity of your entire roofing system.
We use a low-pressure soft washing method designed to kill algae and rinse it away without damaging your shingles. High-pressure washing can strip away granules and void your roof warranty, which is why we rely on soft wash chemistry. Our process combines gentle water flow with biodegradable cleaning solutions that break down algae and prevent it from coming back quickly. When we perform roof cleaning, we also take steps to protect surrounding landscaping and property features from runoff.
When you trust experts for black streak removal, you get more than a clean roof. Here are some of the key benefits you can expect:
Choosing professionals ensures the job is done thoroughly and safely while avoiding unnecessary damage.
Many homeowners worry about plants and shrubs around the house when scheduling roof cleaning. We take special precautions to keep your landscaping safe. Before we begin, we wet down vegetation to reduce chemical absorption, and we rinse it again after treatment. This step gives you peace of mind that your flowers, grass, and trees will stay healthy while we focus on removing algae from the roof.
Black streaks may seem like a small problem at first, but they can quickly spread and harm your shingles if ignored.
