Roof Cleaning Certification Training

The PWNA Roof Cleaning Certification Class teaches contractors how to safely and effectively clean residential and commercial roofs using low-pressure, chemical-based methods. This course covers algae and moss identification, proper chemical selection, application technique, and the safety protocols required when working on pitched and elevated surfaces.

Students learn how to approach different roofing materials — from asphalt shingles to tile and metal — with the correct methods and chemistry, without voiding manufacturer warranties or causing premature wear. The course is built to help contractors deliver results that last, without putting themselves or the property at risk.

This training is grounded in industry-accepted practices and field-tested methodology. The goal is clear: give contractors the knowledge and confidence to clean roofs safely, effectively, and professionally.

This certification is ideal for:

Reduces risk of roof damage and manufacturer warranty issues
Builds chemical application knowledge and safety awareness
Establishes proper protocols for working on elevated, pitched surfaces
Creates consistent, repeatable results across different roofing materials
Builds customer trust through verified professional training
Supports insurance and compliance readiness

Certified contractors are better equipped to handle the complexity of roof cleaning — and better protected when client questions arise.
