Professional Roof Cleaning Services

Your roof is one of the most important parts of your home or business, protecting your property from the elements and contributing to overall curb appeal. Over time, moss, algae, lichen, and dirt buildup can accumulate, causing discoloration, degradation, and even long-term damage. At Diamond PT Window Cleaning, based in Monroe, WA, we specialize in professional roof cleaning services designed to restore the appearance of your roof while preserving its integrity.


Our team has years of local experience and a proven track record of top-rated exterior cleaning. Using gentle, eco-friendly cleaning solutions and safe roof washing techniques, we remove contaminants without compromising shingles, tiles, or other roofing materials.

  • Hospitality and restaurant facilities
  • Community and recreational buildings


We handle large-scale roof cleaning efficiently, removing moss, algae, and dirt while inspecting the roof for signs of wear or damage. Clean roofs improve the overall appearance of your commercial property and help prevent water intrusion or material degradation.

Benefits of Regular Roof Cleaning

Routine roof cleaning offers a range of benefits beyond curb appeal. Maintaining a clean roof protects your property, improves longevity, and prevents avoidable damage. Key benefits include:

  • Extended roof life – Removing moss and algae prevents premature wear and decay.
  • Improved curb appeal – A clean roof enhances the overall appearance of your home or business.
  • Prevention of water damage – Organic buildup can trap moisture, leading to leaks and structural issues.
