The Real Cost of Roof Cleaning: What Homeowners Need to Know

While it may not seem like it, cleaning the roof is an essential maintenance task. As a homeowner, you should have a regular roof cleaning schedule to extend your roof’s lifespan and keep your home’s exterior appealing. 

Fortunately, roof cleaning costs are not very high. We’ll break down the costs associated with cleaning and ensuring your roof is in good condition. So keep reading, to find out how much you might spend on maintaining both the appearance and function of your roof!

What Determines The Cost Of A Roof Cleaning?

To estimate the total price of your roof cleaning, you need to understand the various factors that contribute to the overall cost. 

Type of Roof

The type of roofing material that your roof is made out of impacts the cost of cleaning due to the varying methods and materials to clean different surfaces. For instance, asphalt shingles may require gentle cleaning to prevent damage to the granules, while metal roofs might need specialized treatment and coatings to avoid corrosion. Additionally, delicate materials like clay tiles or cedar shakes demand careful attention to prevent breakage or deterioration during the cleaning process. Consequently, the cost of cleaning can fluctuate based on the quality and characteristics of the roof material.

Roof Size and Complexity

Larger roofs naturally require more time and resources to clean them thoroughly. Additionally, roofs with multiple angles, slopes, and obstacles, such as chimneys, skylights, or dormers, increase the complexity of the cleaning process. These features often require extra care and attention to ensure that every surface is adequately cleaned, which can contribute to higher costs due to the additional labor and specialized techniques.


The accessibility of your roof plays a significant role in pricing. If your roof is easily accessible, such as a single-story home with a low-pitched roof, it will likely be less expensive to clean compared to a multi-story home with a steeply pitched roof that requires special safety measures and equipment.

Extent of Cleaning Needed

For heavily soiled roofs with extensive buildup of dirt, algae, moss, or mildew, the cleaning process becomes more challenging and time-consuming. Cleaning roofs that are this messy may involve additional steps such as pre-treatment, extra scrubbing, or multiple days of cleaning to ensure the thorough removal of stubborn stains and growths. This increased effort translates to higher labor costs and may necessitate the use of specialized cleaning solutions or equipment, contributing to a higher overall expense for homeowners.

Cleaning Method

There are various methods for cleaning roofs, including pressure washing, soft washing, chemical treatments, and manual scrubbing. Each method has its own cost associated with it, with soft washing and chemical treatments typically being more expensive but gentler on the roof’s surface.

Professional vs. DIY Methods

While DIY roof cleaning may seem cost-effective initially, it can harm your roof or cause personal injury if it’s not done properly. Hiring a good roofing contractor ensures that the job is done safely and effectively, which makes up for the cost. Additionally, professional roof cleaning services often come with warranties or guarantees, which can save you money in the long run. Moreover, professionals have access to specialized equipment and cleaning agents that are necessary for effective cleaning but are generally expensive.

Additional Services

Some roofing contractors may offer additional services such as gutter cleaning and roof inspections. These additional services will increase the cost of a roof cleaning but will benefit you in a lot of ways.


Location plays a significant role due to variations in labor costs, demand for services, and environmental factors. For example, in urban areas with higher living expenses, such as major cities, roof cleaning services may be priced higher compared to rural areas. Additionally, regions with a humid climate or frequent rainfall may experience more rapid moss and algae growth, leading to increased cleaning frequency and potentially higher costs.

Let’s see what most homeowners pay for roof cleaning services.

How Much Does A Roof Cleaning Cost On Average?

Here’s what you should expect to pay for a professional roof cleaning service:

Low-End Estimate

On the lower end, basic roof cleaning for a small to medium-sized home with an easy access roof might range from $200 to $500. This estimate typically includes a simple cleaning method like pressure washing or manual scrubbing to remove dirt and debris.

Mid-Range Estimate

For a more thorough cleaning using methods like soft washing or chemical treatments, homeowners might expect to pay between $500 and $1,000. This range also considers factors such as the roof’s size, accessibility, and the extent of cleaning required.

High-End Estimate

For larger homes with complex roofs, heavily soiled surfaces, or roofs requiring additional services like gutter cleaning or roof repairs, costs can exceed $1,000 and may even approach $2,000 or more. High-end services often involve specialized equipment, advanced cleaning techniques, and more labor-intensive processes.

The Average Cost To Clean Different Roofing Materials

Let’s look at the cost of roof cleaning based on the roofing material that needs cleaning:

Cost To Clean Different Roofing Materials

Asphalt Shingles

Typically cleaned using a low-pressure washing method, or soft washing, the cost ranges from $0.30 to $0.70 per square foot. This method ensures thorough cleaning without damaging the shingles.
