Blue Water Exterior Power Washing Services for Roof and Home Exterior Cleaning

Identifying and Removing Black Streaks on Your Roof Caused by Algae

Take a closer look at your roof, especially the north side. Have you ever noticed black streaks running down it? These streaks are caused by Gloeocapsa magma, a type of blue-green algae that feeds on the crushed limestone found in asphalt shingles. Over time, this algae can accumulate and retain moisture, particularly on the shaded north side of your roof. This moist environment encourages the growth of other organisms such as lichen and green moss.

As these organisms continue to grow, they gradually break down the materials in your shingles, which can significantly reduce the lifespan of your roof. We have the right solution to keep your roof cleaner for longer, protecting your investment and maintaining your home's curb appeal.

Could Roof Washing Harm Your Shingles or Landscaping? Expert Soft Wash Safety Explained

When using an experienced professional roof cleaner who employs the correct soft washing methods and proper rinsing techniques, the answer is no — roof washing will not harm your shingles or landscaping.

We utilize dedicated electric pumps and pressure-adjustable power washing equipment that allow us to apply our safe, biodegradable mold, mildew, and roof algae-killing cleaner effectively. After allowing the solution to work, we carefully adjust to low pressure to rinse away the dead algae gently and safely. This process ensures there is no damage to your shingles or any surrounding landscaping.

To further protect your property, we take extra precautions by gently covering any delicate flowers and plants near the washing area with lightweight tarps. This reassures you that your garden and landscaping will remain unharmed throughout the cleaning process.
