Our method of cleaning provides longer-lasting results and no rust corrosion on metal roofs. Pressure washing is a great method to remove surface organic matter. However, the "roots" remain, allowing mold and algae to return quickly.

Sodium hypochlorite is used to kill deeply embedded mold, mildew, and algae at the source.

Follow with thorough rinsing with water and then we apply a bleach neutralizer to ensure complete prevention of metal corrosion. Just like bleach on your hands won't rinse right off, residual bleach stays on a metal roof. We guarantee proper neutralization.

Longer Lasting Results: Our non-corrosive, proprietary post-treatment ensures your roof stays cleaner longer and is safe to use on asphalt, aluminum shake, and metal roofs.
