COMPARE ROOF CLEANING METHODS
Consumer Reports® warns NOT to use a chlorine-bleach solution due to its damaging effects. Consumer Reports® Senior Editor praised the Roof Shampoo® method after he had his own roof cleaned with Roof Shampoo®
As stated by the Centers for Disease Control and Prevention (CDC)
“Chlorine: Lung Damaging Agent - EFFECTS OF SHORT TERM (LESS THAN 8 HOURS) EXPOSURE TO CHLORINE GAS. Chlorine gas is highly soluble in water; therefore, it is severely irritating on contact with moist tissues, such as the eyes, skin, nose, throat, and upper respiratory tract. At low concentrations, chlorine can cause eye and nose irritation, sore throat, and cough. At high exposure levels, irritation of the upper respiratory tract and accumulation of fluid in the lungs (pulmonary edema) contribute to a sensation of choking. Suffocation is the characteristic initial complaint of patient/victims exposed to chlorine.”
How Will I know if a Roof Cleaning Contractor Will Use Bleach on My Roof?
If the Contractor DOES NOT tell you up front that they are NOT using bleach, then they are probably using bleach. Roof cleaning contractors who use bleach often don't advertise or tell you that they use bleach because they know homeowners don't want bleach used around their homes. Even when asked directly, some may still deny that they use bleach. Be insistent about your need to know. Many contractors who use bleach use the term "Soft Wash". Here are some other clues:
If they tell you they use sodium hypochlorite (or SH for short), they are using bleach bleach.
If they tell you they will water down, cover, or spray your plants during the process, they are using bleach.
If they tell you they use of a runoff recovery system to suck up the runoff, they are using bleach.
If they tell you their 'soaps' breakdown into SALT, they are using bleach. (See how salt damages landscaping.)
Many contractors who use bleach use the term "Soft Wash".
Roof Shampoo® does NOT contain chlorine bleach or phosphates. Roof Shampoo® is an eco-friendly proprietary product only available to authorized Roof Shampoo® Contractors. Whereas, many other roof cleaners will use a dangerous home-made chlorine bleach concoction. They mix chlorine bleach with an array of varied chemicals such as phosphates, dish detergents, laundry detergents, assorted surfactants, and ODER-MASKING SCENTS to HIDE THE SMELL FROM YOU of the main ingredient - BLEACH! These haphazard chemical concoctions call into question product reliability, stability, safety and consistency across the board.
NEVER LET ANYONE USE BLEACH ON YOUR ROOF.
Bleach can corrode roof fixtures such as flashing, underlayments, valleys, and boots, dry out shingles, and shorten the life of your roof.
