Your roof protects your home, but over time, it can develop unsightly stains that affect its appearance and longevity. From algae streaks to rust stains, each type of stain requires a specific approach for safe and effective removal. Here’s a comprehensive guide to common roof stains and how to clean them properly.
1. Black Streaks from Algae
What Causes Them?
Black streaks on your roof are usually caused by Gloeocapsa magma, a type of algae that thrives in humid environments. It feeds on the limestone in asphalt shingles, leading to dark, streaky stains.
How to Remove Them:
- Use a soft wash system with a bleach-based cleaning solution to kill the algae at the source.
- Avoid high-pressure washing, as it can damage shingles and spread algae spores.
- Prevent regrowth by installing zinc or copper strips along the roof’s ridge. When it rains, these metals release ions that inhibit algae growth.

2. Green or White Moss Growth
What Causes It?
Moss thrives in shaded, moist areas of the roof, especially if overhanging trees block sunlight. If left untreated, moss can lift shingles, allowing water to seep underneath and cause roof damage.
How to Remove It:
- Gently remove moss with a soft bristle brush, avoiding excessive scraping.
- Apply a soft wash solution to kill moss spores without harming your shingles.
- Trim overhanging branches to allow more sunlight and improve air circulation.
A professional roof cleaning service can safely and effectively remove moss while protecting your roof from damage. Call (843) 696-6121 for expert service.
3. Rust Stains from Metal Fixtures
What Causes Them?
Metal vents, chimneys, and HVAC units can corrode over time. When rainwater runs over rusted areas, it spreads rust stains down the roof’s surface.
How to Remove Them:
- Apply a commercial rust remover that’s safe for roofing materials.
- Use a low-pressure rinse to wash away residue and prevent further staining.
- Replace rust-prone fixtures with galvanized or stainless steel to avoid future stains.

4. White Streaks from Hard Water Deposits
What Causes Them?
White streaks are often caused by mineral deposits left behind from hard water runoff, particularly from HVAC systems or poor drainage.
How to Remove Them:
- Mix a vinegar and water solution to break down mineral deposits.
- Use a soft cloth or sponge to scrub the affected areas gently.
- Rinse with a low-pressure wash to prevent further buildup.
Proper maintenance can prevent hard water stains from forming. Let the experts at Soft Wash Pros handle it for you!
5. Dark Spots from Mold or Mildew
What Causes Them?
Mold and mildew grow in damp, shaded areas of the roof. These dark patches not only look bad but can also lead to roof deterioration if left unchecked.
How to Remove Them:
- Apply a mold-killing soft wash solution to eliminate spores.
- Ensure a thorough rinse to prevent chemical residue from attracting more growth.
- Improve attic ventilation to reduce moisture buildup under the roof.
Regular roof cleanings can prevent mold and mildew from taking hold. Contact (843) 696-6121 to schedule a service.
6. Organic Stains from Leaves and Debris
What Causes Them?
Leaves, twigs, and bird droppings can decompose on the roof, leading to tannin stains and organic buildup.
How to Remove Them:
- Use a roof rake or blower to remove debris regularly.
- Apply a gentle cleaning solution to break down organic matter.
- Install gutter guards to reduce debris accumulation.
Routine maintenance can keep your roof looking its best. Let Soft Wash Pros help with professional cleaning services.
