Black streaks, algae, moss, and lichen don’t just look bad—they trap moisture and slowly wear down your shingles. Simple Clean LLC Power Washing Services provides soft washing roof cleaning that follows the ARMA Roof Cleaning Guidelines for asphalt shingles, delivering a safe, manufacturer-approved clean without high pressure.

The ARMA Roof Cleaning Method (What We Follow)

ARMA recommends a soft wash method—not blasting shingles with high-pressure water. Our process uses a professional cleaning solution (typically water, sodium hypochlorite, and surfactants) to break down staining and kill organic growth, followed by a full rinse after proper dwell time. No “wait for the rain.” That shortcut can fade shingles, weaken the asphalt layer, and shorten roof life.


Protecting Your Roof—and Your Landscaping

A clean roof should never cost you your plants. Every roof cleaning includes property protection: pre-wetting landscaping, controlling runoff, and final rinsing to reduce the risk of plant burn and exterior damage.



When to Clean Your Roof

For many homes, the best time for professional roof cleaning is often around 7–15 years of roof age—before heavy growth causes long-term damage. If a roof is near end-of-life, an inspection by a licensed roofer is recommended before cleaning.

  • âś… Soft wash methods aligned with manufacturer recommendations
  • âś… Controlled application and correct dwell time (no “blast and hope”)
  • âś… Proper rinse-off to protect shingle integrity and color
  • âś… Safer practices for your home, landscaping, and surrounding surfaces
