Find out what the black streaks are on your roof and how you can remove them without a high pressure wash

No matter where you live, there’s a good chance you’ve seen it. Yucky black streaks on your roof.

But what are these black streaks on your roof, and are they causing damage or simply cosmetic? Also, how do you get rid of them without damaging your roof further?

Let’s find out.

The most common cause of the black streaks and stains on your roof are a harmful bacteria called Gleocapsa Magma.

The other destructive plant life on your roof causing those streaks could potentially be:

  • Moss
  • Lichens
  • Algae
  • Mold
  • Mildew
  • Bacteria

When any of the above are present on your roof they are slowly ruining the functionality of your roof as well as decreasing it’s life expectancy, not to mention reducing the curb appeal of your home or building.

What Is Soft Washing?

Traditional pressure washing only blasts off the top of these organisms, much like giving it a haircut, but doesn’t kill it down to the root attaching it to your roof. This allows the bacteria to grow back while the high water pressure accelerates the decomposition of your roof.

Our soft washing process uses an agricultural style sprayer to apply a low pressure, chemical application onto your roof that will kill 100% of these harmful bacteria and other organisms leaving your roof cleaner, longer. No high pressure will ever be used!

What Are The Benefits Of Soft Washing?

By using our soft washing process to clean your roof, Shine is able to:

  • Clean shingle, tile, slate, aluminum, and shake roofs
  • Achieve a 100% kill ratio of the organisms decomposing roofing material
  • Increase the life expectancy of your roof
  • Keep your roof cleaner, longer
  • Lower the roof & attic temperatures resulting in lower A/C costs
