The results are seemingly immediate on a roof, however not long-lasting. Bleach roof cleaning is also required to be repeated in many applications.

Health

The Bleach Cleaning Method can also be dangerous to consumers’ health. This includes not only the owners of the property but neighbors and households nearby. The Centers for Disease Control and Prevention state, “Chlorine gas can be recognized by its pungent, irritating odor, which is like the odor of bleach. The pungent smell may provide adequate warning to people that they are exposed. When chlorine gas comes into contact with moist tissues such as the eyes, throat, and lungs, an acid is produced that can damage these tissues.”

Be Careful

Bleach is a chemical that should be regarded precautiously, as we’ve learned in this article. However, it is not the only chemical used in roof cleaning formulas. Many roof cleaning contractors who use chlorine bleach will design cleaning formulas themselves. These formulas consist of various chemicals such as phosphates (banned in multiple states), dish detergents, laundry detergents, various surfactants, and odor masking scents. Bleach and the above chemicals will corrode roofing materials and metal (even in weak concentrations). High strength chlorine bleach will accelerate the damage – especially when the roof has not been adequately rinsed.

Many contractors who use bleach will tell you that they follow ARMA guidelines. Asphalt Roofing Manufacturers Association (ARMA) recommends using bleach to remove living algae from roofs. However, their recommendation is given with precautions. “Take proper precautions to protect landscaping and surrounding areas from the chlorine bleach solution. Use appropriate personal protective equipment when working with chlorine bleach. Algae will disappear and wash away with subsequent rains. In severe cases, it may take more than one bleach treatment to kill all of the moss. Never use a pressure washer to clean an asphalt shingle roof as this will cause granule loss and very likely premature failure of the roof system.”

Please be careful

If you are interested in using a bleach product, please use proper precautions for plants and landscaping and ensure that the contractor does not pressure-wash the roof. It is also recommended to warn neighbors of the potential odor with bleach roof cleaning. Finally, before a bleach cleaning, check with your local county office to see if permits are required due to widespread odor.

Takeaway

Bleach cleaning is quite common, but contractors do not typically discuss the methods or effects. Be sure to discuss all washing techniques with a contractor to learn about the chemicals they use in the process.
