Black roof streaks are caused by Gloeocapsa Magma algae that damages shingles and increases energy costs. Professional soft wash roof cleaning removes algae safely without pressure, protects shingles, and restores your roof’s appearance and performance.
If you have noticed long black streaks spreading across your roof, you are likely seeing Gloeocapsa Magma algae at work. This airborne algae is common along the East Coast and feeds on the limestone filler found in asphalt shingles. Over time, it weakens roofing materials and creates areas where water can seep in. Beyond structural damage, algae buildup also affects your home’s energy efficiency. A professional non-pressure roof cleaning removes the algae safely without harming shingles. Instead of replacing your roof prematurely, soft wash roof cleaning restores its appearance, protects its lifespan, and helps prevent rising energy costs.
What Is Gloeocapsa Magma and Why Is It Dangerous?
Gloeocapsa Magma is a type of algae that spreads through airborne spores. Once it lands on your roof, it begins feeding on the limestone filler used in many shingles. The dark streaks you see are actually protective coatings created by the algae.
If left untreated, this growth:
- Weakens shingles
- Shortens roof lifespan
- Traps moisture
- Increases risk of leaks
Over time, algae can cause premature aging of your roofing system, leading to expensive repairs or early replacement.
The Immediate Impact on Energy Costs
The problem isn’t just cosmetic. Clean shingles reflect sunlight efficiently. When algae coat the surface, it reduces that reflective ability.
As a result:
- More heat enters your attic
- Indoor temperatures rise
- Your AC system runs longer
- Monthly energy bills increase
Even a small rise in attic temperature can significantly affect cooling costs during summer months.
Why High-Pressure Washing Can Damage Your Roof
Some homeowners attempt to remove stains using high-pressure washing. While it may seem effective at first, pressure washing can:
- Strip protective granules from shingles
- Cause cracks and water intrusion
- Void roofing warranties
- Reduce roof lifespan
Roof cleaning should never rely on force. The correct approach focuses on safe removal, not surface blasting.

Soft Wash vs Pressure Washing: What’s the Difference?
When deciding how to clean your roof, understanding the difference is important.
| Feature | High-Pressure Washing | Soft Wash Roof Cleaning (Envirowash) |
| Cleaning Method | Forceful water spray | Low-pressure application + cleaning solution |
| Shingle Safety | Risk of damage | Safe for roofing materials |
| Algae Removal | Surface removal only | Kills algae at the root |
| Longevity | Stains may return quickly | Longer-lasting results |
Soft washing doesn’t just remove stains, it treats the underlying growth.
How Often Should a Roof Be Cleaned?
Most homes benefit from professional roof cleaning every two to three years, depending on local climate, shade coverage, and moisture levels. Properties surrounded by trees, located in humid regions, or exposed to frequent rainfall may need more frequent service to prevent algae, moss, and debris buildup. Regular roof cleaning helps protect shingles, improves appearance, and reduces the risk of long-term damage. By scheduling routine maintenance, homeowners can extend the life of their roof, avoid costly repairs, and keep their property looking clean and well-maintained year-round.

Yes. Algae gradually weakens shingles by feeding on their materials. If left untreated, it can shorten the lifespan of your roof and increase the risk of leaks.
Does roof cleaning really lower energy bills?
Clean shingles reflect sunlight more effectively. Removing algae helps reduce attic heat buildup, which can lower strain on your air conditioning system.
