What Chemicals are Used to Clean Roofs?

Roof cleaning is not an easy feat, and we don’t recommend you attempting a DIY clean yourself. If you’ve watched a professional Orlando roof cleaning company at work, you’d know that chemicals are often used during the washing. If you want to learn more about the commonly used chemicals, keep reading to find out.

What Chemicals are Used to Clean Roofs?

Sodium Percarbonate

Sodium percarbonate is a chemical compound that includes sodium carbonate and hydrogen peroxide. It’s commonly used as an industrial cleaner, but it can also be found in many household cleaners like OxiClean.

However, there are some concerns regarding the safety of using this product around animals or children due to the fact that hydrogen peroxide has bleaching properties.

Sodium Hydroxide

Sodium hydroxide is a strong alkaline base also known as lye. It’s commonly used in the soap-making process because it helps neutralize fatty acids found in most oils. However, using this chemical on roofs should be done carefully because of its corrosiveness levels that can damage concrete surfaces or rust metal objects, which is why only roofing experts should use these chemicals.

Once sodium hydroxide is used for roof cleaning, it should be thoroughly washed away afterward, as it can be damaging if left behind.

Sodium Hydrochlorite

Sodium hypochlorite is also known as bleach, and it’s both a strong oxidizing agent and disinfectant. The chemical formula for sodium hypochlorite is NaClO which means that one atom of chlorine (Na) binds to two atoms of hydrogen (H), while the other oxygen molecule bonds with another sodium ion (ClO). 

Thanks to its potency and effectiveness at removing oil stains, it is one of the most common chemicals for cleaning roofs. However, it shouldn’t be used on colored surfaces or where children can access them due to its high toxicity levels.

It is also crucial to note that sodium hypochlorite should be properly diluted because of its strength. 

Again, such chemicals should be left in the hands of professionals who are well trained and have the knowledge to handle them safely. It’s also vital that the Sodium Hydrochlorite mixture is sprayed onto a cool surface to avoid the risk of heat damage to your roof.
