On-Site in Nashville: A Real-World Example

Today, we're cleaning a TPO roof in one of Nashville's most sought-after areas. This neighborhood, known for its high-profile residents, is a testament to the growing demand for professional pressure washing services.

Equipment and Tools: The Essentials

One of the most critical aspects of pressure washing is having the right tools. In this video, Ben Wilson uses a smart stream remote downstream injector, allowing him to control the chemical flow directly from the roof without climbing down repeatedly.

Step-by-Step Process

  1. Initial Inspection: Start by inspecting the roof and gutters. Look for any construction remnants or potential problem areas.
  2. Setup: Ben had to use multiple ladders to reach different roof levels safely.
  3. Downstream Mix: For this nearly new TPO roof, a downstream mix of about 1% is sufficient. This mix is gentle yet effective, preventing damage while cleaning thoroughly.
  4. Cleaning Technique: Use a ball valve for moderate pressure cleaning. Spray in the direction that aligns with the roof's slope to avoid lifting the TPO material.

Expert Tips

  • Avoid High Pressure: High pressure can damage TPO roofs. Always use moderate pressure and spray in the right direction to ensure safety.
  • Pre-Wet Metal Frames: Before applying chemicals, pre-wet any metal frames to prevent staining or damage.
  • Upsell Opportunities: Always look for additional services you can offer, such as parking lot restriping, to increase your ticket price.


Commercial pressure washing is more than just spraying water. It's about understanding the nuances of each surface and using the right techniques to ensure a thorough and safe clean. Whether you're cleaning a high-profile property in Nashville or a commercial building elsewhere, these tips will help you achieve professional results.
