How does the Roof-A-Cide® process work?

Roof-A-Cide® is a roof cleaning and stain preventative process. It works in two steps. First, your roof is cleaned one last time (if needed).

Then, Roof-A-Cide® stain preventative is lightly sprayed on the clean roof. It chemically bonds to the roof, preventing airborne spores from growing and causing stains. No rinsing is required. It continues to kill any algae, mold, or fungus for at least two years, and the roof is cleaned every time it rains.

Is Roof-A-Cide® a “green” product?

Absolutely! Roof-A-Cide® does not contain toxic or caustic chemicals and is safe, eco-friendly, and 100% biodegradeable. It’s also made with pride in the U.S.A.

Roof-A-Cide® is the ONLY roof stain preventative available that’s approved by both the EPA and Florida Department of Agriculture.

Is Roof-A-Cide® guaranteed?

Yes, it is unconditionally guaranteed for at least two years by both Avery Roof Services and Roof-A-Cide® to prevent mold, mildew, fungus and algae growth and the stains they create. Roof-A-Cide® applicators are fully trained and certified by the manufacturer, licensed and insured.

How is this different from biocide roof cleaning?

Biocides are caustic and toxic chemicals such as chlorine, bleach, TSP, sodium hypochlorite, or sodium hydroxide, and are not safe for children, pets or plants. Even in weak concentrations, chlorine bleach solutions will corrode metal, damage your roof and the underlayment, and greatly reduce its lifespan — especially when the roof is not rinsed properly. Roof-A-Cide® is cost-effective because it requires fewer treatments and will lengthen the life span of your roof.

How is this different from soft washing?

Soft washing (also known as non-pressure or no-pressure roof cleaning) is a low-pressure cleaning method, but typically uses the same harsh chemicals.

Are Roof-A-Cide® products approved by roofing manufacturers?

Yes, major roofing manufacturers have tested and approved Roof-A-Cide® products for use on their materials, including GAF Roofing, TruSlate, PolyGlass, MonierLifetile, US Tile, Boral Roofing, Metro Roof Products, and Gerard Roofing.
