Estimating a Power Wash Roof Cost
Power washing a roof can boost a property’s curb appeal and extend the lifespan of certain roofing materials. However, it’s important to know how contractors estimate the power wash roof cost and avoid hidden fees!
High-pressure washing
A high-pressure washing is a common and quick way to remove mildew, mold, algae, and dirt from your roof. This method is effective and nontoxic, but it can damage your roof tiles and shingles. It also removes granules from the surface of your shingles, which can shorten their life. It is best used on metal roofs at a low psi setting.

A roof that is not clean can be dangerous and affect the health of your family. A dirty roof can also reduce the curb appeal of your home and detract from its value. Fortunately, professional roof cleaning services can help you get the look you want at an affordable price.
When choosing a company, make sure to consider the location and size of your roof. These factors can significantly influence the price of a roof cleaning service. Also, beware of hidden fees that can increase the cost of your roof cleaning service. These include labor setup time, mobilization time, and hourly charges for power washing.
Low-pressure washing
The low-pressure washing method is an effective and safe alternative to high-pressure cleaning. It combines cleaning solutions with low pressure to clean surfaces and kill moss, mildew, algae, and lichen. The resulting surface is smooth and clean, and can be easily restored to its original condition by a professional. It also helps reduce the risk of damage to the roof, siding, and gutters.
It is particularly useful for houses with tile roofs, which are more prone to cracking under high pressures. This method is not recommended for roof shingles, since the use of 1,300 to 2,800 pounds per square inch (psi) of pressure can damage them and possibly void the warranty.
It is also safer than high-pressure washing, which may force water into the soffit and siding of a house. This trapped moisture can breed mold and algae growth and cause wood to rot.
Soft washing
Unlike power washing, soft washing is an eco-friendly method that uses a mix of water and cleaning solutions to remove mildew, algae, and moss. This cleaning technique is safe for most structures and avoids removing granules from the roof surface. It is also less expensive than high-pressure washing.
Humid areas are prone to mold, mildew, moss, and algae growth on and around the home’s exterior walls and roof. These organisms can deteriorate the roof and other materials and cause water leaks. They can also erode concrete and brick surfaces, so it is important to clean them regularly.

Unlike pressure washing, which can damage shingles and tiles, soft wash uses low-pressure hoses (under 1,000 psi) and scrub brushes to remove growth on the roof. It is especially effective in removing moss and algae from roofs, and it won’t damage or void your warranty. However, it is more labor-intensive than high-pressure washing and will cost you between some dollars per square foot.
Chemicals
Chemical washing costs less than a dollar per square foot and involves spraying a cleaning solution, usually bleach, on the roof. This method is best for mossy roofs and can also kill off lichen. It is a safe alternative to pressure washing because it doesn’t involve pressurized water. However, it’s important to check the strength of your tiles to avoid causing damage. This cleaning method is recommended for tar and gravel, rubber, and tile roofs that aren’t suitable for high-intensity water pressure.
