Your roof takes a beating from the elements—rain, wind, dirt, algae, and moss all build up over time. Left unchecked, this grime not only makes your home look older but can also cause long-term damage. Pressure washing is one of the fastest ways to restore your roof’s appearance and extend its lifespan. But before you book a service, you probably have one big question: How much does it cost to pressure wash a roof?
The price isn’t one-size-fits-all. It depends on factors like roof size, material, level of buildup, and even where you live. A small asphalt roof will cost far less to clean than a large tile roof covered in thick moss. Hiring a professional saves you time and keeps your roof safe, but DIY can seem like a cheaper alternative—if you know what you’re doing.
So read on—we’ll break down average costs, what affects pricing, and whether professional cleaning is worth it. By the end, you’ll know exactly what to expect and how to get the best value for your money.

How Much Does It Cost to Pressure Wash a Roof
The cost of pressure washing a roof typically ranges between $250 and $800, depending on the roof’s size and the level of cleaning required. Most companies charge between $0.15 and $0.60 per square foot, but prices can increase for larger homes or roofs with stubborn stains like moss and algae.
Cost Breakdown by Roof Size
- Small Roof (Under 1,000 Sq. Ft.) – Expect to pay $150 to $400. These are often single-story homes with easy access, making them quicker and cheaper to clean.
- Medium Roof (1,000–2,000 Sq. Ft.) – Costs typically range from $300 to $900, depending on dirt buildup and cleaning methods required.
- Large Roof (2,000+ Sq. Ft.) – Prices can go up to $600 or more, especially for multi-story homes that require more labor and time.
While size is the biggest factor in pricing, the complexity of the job also plays a role. A simple, flat roof costs less than one with steep slopes or hard-to-reach areas. The type of buildup—whether it’s just dirt or thick layers of moss—can also affect the final price.
So read on—next, we’ll break down the key factors that determine roof cleaning costs and what to expect when hiring a professional.
Factors That Affect Roof Pressure Washing Costs
The price of roof pressure washing isn’t a fixed number—it changes based on several key factors. Some roofs are quick and easy to clean, while others take extra time and effort, increasing the cost. Here’s what determines the final price:
1. Roof Material and Its Impact on Pricing
Not all roofs can handle the same level of pressure. Asphalt shingles require a soft wash to prevent damage, while metal roofs can withstand higher pressure. Tile and wood shake roofs need extra care, making the process longer and more expensive. If special cleaning solutions are required to prevent damage, that also adds to the total cost.
2. Level of Dirt, Moss, and Algae Growth
A lightly dirty roof costs less to clean than one covered in thick moss and algae. Organic growth not only looks bad but can also weaken roofing materials, requiring more time and cleaning solutions to remove safely. If your roof hasn’t been cleaned in years, expect a higher bill.
3. Roof Pitch and Accessibility
A flat or low-slope roof is easier and safer to clean, keeping costs down. Steeper roofs require special equipment, added safety measures, and more time, all of which increase the price. If your roof is surrounded by trees or other obstacles that make it difficult to access, labor costs may go up.
4. Regional Pricing Differences
Where you live plays a big role in pricing. Areas with a high cost of living generally have higher service rates. Homes in regions with frequent rain, humidity, or tree cover may also see higher costs due to increased demand for roof cleaning services.
5. Additional Services That Can Increase the Cost
Many homeowners bundle roof cleaning with other services like gutter cleaning or applying a protective treatment to slow down moss and algae growth. While these add-ons increase the upfront cost, they can help extend the time between cleanings, saving money in the long run.
So read on—next, we’ll compare DIY roof cleaning with hiring a professional and see which option gives you the best value.
DIY vs. Hiring a Professional: Cost Comparison
Cleaning your roof yourself might seem like a way to save money, but is it really worth it? Let’s break down the costs, risks, and time involved in DIY vs. hiring a professional.
A basic pressure washer rental costs between $50 and $150 per day, while buying one can range from $300 to $1,000. Add in cleaning solutions, safety gear, and the time it takes to learn the right technique, and the savings start to shrink. More importantly, if you use too much pressure or the wrong method, you can strip shingles, crack tiles, or force water under your roof—leading to costly repairs.
Hiring a professional may cost $300 to $900, but you’re paying for experience, safety, and efficiency. Professionals know the right pressure levels for different materials, have the equipment to reach steep or high roofs, and use specialized treatments to prevent future buildup. They also spot minor roof issues before they turn into expensive problems.
So read on—if you want to stretch the time between cleanings and save money in the long run, we’ll cover the best ways to reduce buildup and keep your roof looking great.
How to Save Money on Roof Pressure Washing
- Get Multiple Quotes – Prices vary between companies, so compare at least three quotes before choosing a service. Look for experienced professionals with good reviews to ensure quality work at a fair price.
- Schedule During Off-Peak Seasons – Many pressure washing companies offer lower rates in the winter or early spring when demand is lower. Booking ahead or asking about seasonal discounts can save you money.
- Bundle Services – Many companies offer discounts if you combine roof cleaning with gutter cleaning, house washing, or driveway pressure washing. Bundling services can reduce the total cost.
- Keep Up with Regular Maintenance – The longer you wait, the more buildup forms, making cleaning more expensive. Scheduling routine cleanings prevents excessive moss and algae growth, reducing the time and effort needed for each job.
- Ask About Loyalty or Referral Discounts – Some companies offer discounts for repeat customers or referrals. If you plan to use the same company in the future or recommend them to others, you may get a better deal.
