Cost of Roof Cleaning

The cost of roof cleaning varies depending on the size of your home and the type of material you have. It’s best to get a free quote from a local roof cleaner before getting started. A roof that’s less than 1,000 square feet costs an average of some cents per square foot to clean, while a 1,700-square-foot roof costs around some dollars per square foot.

Pressure Washing

A clean roof can improve a home’s curb appeal instantly. It can also enhance the exterior appearance of a business.

A dirty roof can create a damp, humid environment that can promote mold and mildew growth. These organisms can be harmful to both people and property, especially if left unchecked. This can lead to costly repairs later on, unless the build-up is cleaned off regularly. Pressure washing is one of the most cost-effective methods for roof cleaning, but it must be done carefully. This is because it can damage some roofing materials. Professional pressure washing services use high-pressure washers to spray water at dirt, moss, and other debris. They can also be used to remove hard-to-clean stains.

Chemical Washing

Chemical washing is a cost-effective way to get rid of moss, mold, and algae that can build up on your roof over time. It uses specialized cleaning solutions and low-pressure water to remove these organisms gradually over several days.

This method is more expensive than pressure washing, but it does a better job of getting rid of the growth on your roof. It also doesn’t damage your roofing materials like power-washing.

During chemical cleaning, a variety of acids are used to break down the bonds between foulants and membrane surfaces. Acids are most effective at removing precipitated salts and mineral scale. They also have a detergent action due to their phosphate groups, and they can be combined with chelating agents.

Soft Washing

Soft washing is a cost-effective method of roof cleaning that uses special cleaning solutions to remove mildew, bacteria, and algae from your roof. These chemicals are safe, biodegradable, and recommended by roof shingle manufacturers.

It begins with a special cleaning solution that contains surfactants, bleach, and algaecides. These cleaning agents seep into the nooks and crannies of your roof, dissolving dirt and grime that can be difficult to reach with a hose or pressure washer.

The cleaning agent also kills mold and mildew spores, moss, and any other plant or fungi that have grown on your roof. This prevents further damage to your roof and keeps anything from growing back. Typically, a soft wash system consists of a truck-mounted pump sprayer, cleaning solution mixture, and water at low pressure. This enables the solutions to dwell on the roof for the appropriate amount of time to break down stains and fungus. The solution is then rinsed away with water at low pressure to ensure that the dissolved residue is not left behind.

Zinc Strips

Zinc strips are a popular method for preventing the growth of moss, algae and lichen on roofs. They are inexpensive and easy to install. They work by releasing zinc ions into the air when it rains, preventing the growth of these plant materials. They also help to keep your roof looking new and fresh.

However, they don’t work effectively if they are not installed correctly. This can lead to a lot of problems, including leaks and broken seals. First, the strips must be placed flat and even on the roof. This is done by placing them underneath the ridge cap on both sides of the roof peak. It’s also important to place them below the chimney, skylight and gables, as these areas tend to get a lot of rainwater.
