A. No Pressure, Soft Chemical roof cleaning, is a Toxic Chlorine and other chemical mixture, no rinse method. Also known as; Certified, Soft Washing, Foam, Bio-gel, Biocide, Non pressure or No pressure roof cleaning. Runoff will kill plants and shrubs.
Chemical cleaning contractors use cheap, toxic corrosive mixtures; DIY Fruit scented, citrus, fruit sauce cleaner mixes; Pool Chlorine, Ammonia, Sodium Hypochlorite or Sodium Hydroxide(Lye). The toxic chemical cleaner mixture is left on roof, not rinsed off.
Expect temporary results. Not a safe, cost-effective long term solution. Unfortunately, harsh chemical roof cleaning contractors are virtually unregulated. Many are unlicensed or uninsured.
Chlorine Bleach is Corrosive and should not be used for roof cleaning. Especially, when used in high strength (50 – 80%) concentrations throughout Florida. Chlorine Bleach should always be rinsed off to avoid damage to the roof. Requires repeating the process, in 6-12 months depending on where you live.
NO written warranty. Not eco or plant friendly. All plants and shrubs must kept wet during and after cleaning. Harsh Chemical Soft Washing methods will dry out the roof prematurely and shorten it’s service life. Pest control service products applied are neutralized.
Q. What is a biocide roof cleaner?
A. Biocide or foaming disinfectant cleaners are common and typically used in food processing/handling equipment and other industrial applications have found their way to your roof. OTC (Home and Hardware stores) cleaning products are sold as; biocides, bio cleaners, bio foams, bio blockers, cationic surfactant no rinse methods and other citrus odor/color cleaners. QUATS – (Quarternary Ammonium Compounds). Ex: alkyl dimethyl benzyl ammonium chloride or Cationic Surfactant Ex: alkyl benzene ammonium chloride. Safer for your roof than Chlorine, but, not EPA Approved. Runoff kills plants and shrubs.
QUATS and cationic surfactant cleaning products are sprayed on the roof, not rinsed and will require 3-6 months and adequate rainfall to see results. Ex: alkyl benzene ammonium chloride. Follow up cleanings are an additional cost and a frequent disruption to your community. Cleaning with Quaternary Ammonium Compounds requires repeating the process in 3 – 6 months depending on where you live.This is NOT a cost-effective, long term solution.
- FACT: Bleach and TSP (Tri sodium phosphate) will corrode metal (even in weak concentrations) and High-Strength Chlorine Bleach (Pool Chlorine) will accelerate the damage – especially when the roof is not rinsed properly.
- FACT: No Roofing Manufacturer in the US recommends the High-Strength Chlorine Bleach solutions that are applied and left on roof all over Florida and increasingly throughout the US.
