Metal Roof Cleaning
Why worry about a dirty roof? Because a clean and preserved roof looks a lot better than a re-roofers bill!
The worst thing to do, however, is to do nothing at all!
We do not use high pressure. We use a Soft-Wash System.
Cleaning a metal roof to remove algae and organic growth is vital to prevent moisture entrapment, protect protective coatings, and maximize the home’s energy efficiency. While metal roofing panels are inherently durable and resist biological penetration better than asphalt shingles, unchecked organic growth can cause long-term structural and cosmetic problems.
Different Types of Metal Roofs We Clean
- Standing seam metal roofs
- Stone coated metal
- Corrugated/exposed fasteners metal roof
- Stamped metal shingles/shake
Why Cleaning Organic Growth Matters on Metal Roofs
- Prevents Corrosion and Rust: Debris, pollen, and leaves trap moisture against the metal surface. Over time, this constant damp environment breaks down protective paint systems (such as PVDF or SMP coatings) and corrodes the underlying metal.
- Avoids Acid Damage: Certain types of biological growth, such as lichen, produce acids that etch into bare metal and destroy coating adhesion over a 3-to-5-year period.
- Restores Energy Efficiency: Dark streaks of algae absorb solar heat rather than reflecting it. Cleaning restores the roof’s natural reflective capacity, keeping attic temperatures lower and lowering cooling costs.
- Protects Manufacturer Warranties: Many major coating manufacturers explicitly require routine cleaning schedules to maintain active warranty coverage.
Regularly cleaning a metal roof does more than preserve its appearance; it fundamentally prevents early structural failure, protects critical structural hardware, and guards against permanent paint damage. While metal is highly durable, leaving organic debris, biological growth, or atmospheric pollutants uncleaned can cut its 40-to-70-year service lifespan.
