What is chlorine-bleach roof cleaning?

Some roof cleaning contractors use sodium hypochlorite, also known as chlorine bleach to remove stains, moss, and lichens off the roof. They mix the chlorine bleach in high concentrations with other chemicals like trisodium phosphate and spray it on the roof. They wait for the chemical to dry, after which they re-apply it on the roof several times to remove stubborn stains, algae, and other microorganisms. 

The bleach method is less expensive compared to high-pressure power washing and low-pressure roof cleaning. This is because the chemicals are less expensive, and this method does not require the technicians to get on the roof to rinse or inspect after spraying. On the other hand, exposure to the fumes, odors, and fluids from the strong chemical treatment can pose potential harm to children, pets, plants, shrubs, and trees on your landscape. If your cleaning service provider recommends the use of chlorine bleach, make sure he implements a runoff recovery system or covers the plants and shrubs during the cleaning treatment. Keep your children and pets away from your house during the roof cleaning process.

Top reasons to hire a roof cleaning contractor

The roof is an important part of your home’s exterior and plays a pivotal role in determining the value of your home. Here are some good reasons for why you should hire a professional for roof cleaning in Nassau County:

Points to consider before hiring a roof cleaning provider

You do not want to hire a contractor that uses a high-pressure washing system. This can compromise the health of your shingles by removing its granules coating. Make sure to inquire about the type of cleaning products and solutions a contractor uses. You want to avoid contractors that use chlorine-based chemicals.

Also, ask the company as to what measures they will take to prevent possible damage to your landscape and property from runoff. Lastly, choose a contractor who gives you a warranty for at least 2-5 years after professional cleaning services.
