Roof Blow Cost
The average cost for a roof blow is $0.05 to $0.10 per square foot. This is the simplest kind of cleaning, where a leaf blower or other blowing device is used to blow away any leaves or debris that may have settled on the surface. It is a good option for general cleaning on homes with lots of trees nearby, but it will not be very effective against stubborn marks or moss.
Zinc Oxide Application Cost
The average cost for zinc oxide application ranges from $0.05 to $0.15 per square foot. Zinc oxide application is a popular choice on surfaces that are prone to growing moss and algae. Zinc is a toxic substance for moss and lichens, preventing them from growing in the first place. Professionals can even apply zinc strips to your roof or dust it with a zinc oxide powder. It is a good choice for very rainy areas where moss grows more easily, but the strips need to be replaced every few years.
Roof Chemical Wash Cost
The average cost for zinc oxide application ranges from $0.05 to $0.15 per square foot. A chemical wash, also known as a non-pressure wash, involves spraying a chemical cleaning solution. The solution may be lye or sodium hydroxide and will kill lichens and algae. Usually, it does not pose much risk to your roof, but the chemicals can damage weak tiles. So, it should be thoroughly checked over for weakness before starting this cleaning. It also will not clear away debris, so it is best-suited for mossy surfaces.
Pressure Wash Cost
The average cost to pressure wash roofs is between $0.20 and $0.70 per square foot. Pressure washing is the most popular and common form of roof cleaning. It involves using a pressure washer to blast high-pressure unheated water, getting rid of debris, dirt, stains, and some moss and algae. On the downside, the high-pressure nature of this cleaning method can potentially damage any weak tiles or shingles you might have. And, it will not kill moss at the core, so a chemical-based clean may be needed if your roof has a lot of plant life on it.
Power Wash Roof Cost
The average cost to clean roofs with a power wash ranges between $0.20 and $0.70 per square foot. Power washing uses high-pressure streams of extremely hot water to remove dirt, moss, and other debris from a roof or other surface. It removes mildew, mold, salt, and more. The addition of heat makes it excellent at removing any debris that is adhered to the roof. It can also kill moss through huge blasts of hot water directed in their location.
Low-Pressure Roof Cleaning Cost
The average cost for low-pressure cleaning is between $0.30 and $0.70 per square foot. It is really similar to a pressure wash, but it uses gentle chemicals. This cleaning method is more gentle while also being more thorough. It kills moss and algae and rinses away dirt and debris. It will not be quite as effective on stubborn marks and stains, but it is a good choice for an all-over roof clean and will not pose much risk to its structural integrity.
Soft Wash Roof Cleaning Cost
The average cost for a soft wash cleaning ranges from $0.30 to $0.75 per square foot. The soft wash technique is becoming more popular with homeowners around the world due to its in-depth approach. It is quite similar to a pressure washing clean but is extremely low pressure and involves using chemicals, bleach, soap, and water to clean. For a typical soft wash, a diluted bleach solution is first applied, killing any moss, lichens, or algae, as well as cleaning the roof of bacteria and killing most everything in sight. Then, it is rinsed off with water. This is The most common method we use here at Jabez Power Washing.
