How Much Does it Cost to Get Your Roof Cleaned?

The roof of a house isn’t the foundation, but we wouldn’t be safe without one. A roof keeps out the elements and gives us a safe place to live. However, it is exposed to rain, dirt, debris and can build up moss, mold, and other plant growth over time.

Being exposed to all of these elements can damage your home’s roof can be expensive to replace. Severe damage can lead to potentially needing a new roof altogether. Having your roof professionally cleaned regularly helps keep your roof in good condition.

Average Cost to Clean a Roof

The national average cost to clean a fifteen hundred square foot roof is just over six hundred dollars. Many factors go into the price, such as location, size, and the type of cleaning.

Roof Cleaning Options Cost Per Square Foot

Most contractors charge by the square foot for professional roof cleaning. Larger roofs will have a higher cleaning cost. Charges range from between ten cents and sixty per square foot, but some companies charge differently.

There might also be extra charges for roofs that require extensive cleaning. For example, a roof with moss will need a chemical cleaning solution rather than just a pressure wash.

Roof Blow Cost

Roof blowing is the most basic type of cleaning. Cleaning crews will take a high-powered leaf blower to blow any debris or leaves on the roof. If you have leaves or residue on your roof, this option is an excellent choice as a general preventative—this service, on average, costs between five and ten cents per square foot.

Chemical Wash Cleaning Cost

They are sometimes referred to as a non-pressure wash where they use a chemical wash. Professional cleaners will first spray a cleaning solution onto the roof. This solution will help to kill algae and other plant life that is starting to grow.

Over time, these chemicals can weaken tiles, but overall, this wash doesn’t pose much risk to your roof. Professionals will know what to look for and notice any weaknesses in your roof before they clean.

This type of roof cleaning only cleans away moss and other growths on your roof. It won’t remove any leaves or debris. If you have a mossy roof, expect to pay between twenty and thirty cents per square foot.

Pressure Wash Cleaning Cost

Pressure washing your roof is the most popular method of roof cleaning. Professionals will use a pressure washer to remove debris, dirt, and some moss. This cleaning can also remove stains.

While your roof may need a good deep cleaning, pressure washing can cause some damage to weak tiles. It may remove moss, but it won’t remove it, and the algae will grow back. On average pressure, washing cleaning will cost between twenty and seventy cents per square foot.
