Pressure washing a roof is an essential maintenance task for American homeowners aiming to boost curb appeal and extend roof life. Costs to pressure wash a roof vary based on the roof’s size, type, condition, and geographic location. Understanding the factors that influence pricing helps homeowners budget accurately and select a reputable contractor for the job.
| Factor | Details | Influence On Cost |
|---|---|---|
| Roof Size | Measured in square feet; larger roofs require more time and resources | Major |
| Roof Type | Material (shingle, tile, metal, etc.) & complexity (steepness, stories) | Major |
| Cleaning Method | Pressure washing vs. soft washing | Moderate |
| Condition & Dirt Level | Heavy moss, algae, or debris may need extra work | Moderate |
| Location | Costs differ by region due to labor rates and environmental factors | Moderate |
| Access & Safety | Difficult-to-reach or steep roofs increase the cost | Minor to Major |
Average Cost To Pressure Wash A Roof In The U.S.
The typical cost to pressure wash a roof in the United States ranges between $350 and $750, with most homeowners paying around $500. Several factors can pull the price lower or send it much higher—especially for large or especially dirty roofs.
The table below summarizes general costs based on national averages:
| Roof Size (Sq Ft) | Cost Range | Notes |
|---|---|---|
| 1,000–1,500 | $300–$500 | Single-story, standard tilt |
| 1,500–2,500 | $400–$700 | Larger single/medium double-story |
| 2,500–4,000 | $650–$1,000 | Multi-story or complex architecture |
Minimum charges typically start around $200-$250, even for smaller jobs. Extremely large or intricate roofs, or those with significant moss or lichen, may cost over $1,000 to clean.
Key Factors Affecting Pressure Washing Roof Costs
Roof Size And Square Footage
Roof size is one of the most significant determinants of cost for roof pressure washing. Most contractors charge either by the square foot or a flat rate tied to typical roof dimensions. Pre-inspections ensure accurate measurements; expect to pay $0.20–$0.40 per square foot for an average composition shingle roof.
Roof Type And Material
- Asphalt Shingles: Easy to clean, lower cost, but require careful pressure to avoid damage.
- Clay/Concrete Tile: Durable, but may need a softer wash method due to their porosity; moderate cost.
- Metal Roofs: Basic cleaning is straightforward, but safety systems and extra precautions can increase costs.
- Wood Shingles or Shakes: Require very low pressure to prevent damage, often costing more due to extra care.
- Slate: Expensive to clean due to fragility and complex setup.
Steep pitches, multi-level roofs, or complex rooflines cost more because they require more setup, time, and safety gear.

Method: Soft Wash Vs. Pressure Wash
“Pressure washing” is often used generically, but most roofs require a “soft wash” method. High pressure may void warranties or cause shingle loss and leaks. Soft wash uses eco-friendly solutions and low-pressure water to safely remove algae, moss, and lichen.
- Soft Washing: Standard option for most residential roofs, safe for shingles and tiles; costs $0.30–$0.75/sq ft.
- Pressure Washing: Only appropriate for certain metal or concrete roofs, usually less expensive ($0.15–$0.30/sq ft), but higher risk for typical residential roofs.
Region And Local Labor Rates
Location matters: Coastal areas, large cities, and affluent suburbs often experience higher labor rates and additional regulations. Demand for cleaning services, local competition, and environmental ordinances also influence prices. For example, prices are often 10–25% higher on the West Coast or in major Northeast cities than the Midwest or South.
Condition Of The Roof
Roofs with heavy moss, algae, or thick debris will cost more to clean. Pre-cleaning, manual scraping, or multiple treatments increase both time and chemicals required, impacting the final price.
Accessibility And Safety Concerns
Challenging access, such as steep pitches, multiple stories, or roofs with many dormers and valleys add complexity to cleaning jobs. Extra safety equipment, insurance, and time spent on setup will raise prices substantially.
Pressure Washing Roof: Material-Specific Cost Guide
| Roof Material | Estimated Cost Per Sq Ft | Special Considerations |
|---|---|---|
| Asphalt Shingle | $0.20–$0.40 | Requires low pressure; avoid shingle damage |
| Clay/Concrete Tile | $0.30–$0.60 | Soft wash recommended; tiles can crack |
| Wood Shingles | $0.40–$0.70 | Very low pressure; risk of splitting |
| Metal | $0.20–$0.45 | Safer for moderate pressure |
| Slate | $0.50–$1.00 | Brittle; experienced pros only |
Additional Cost Considerations For Roof Pressure Washing
Minimum Charges
Most contractors have a minimum service charge, usually between $200 and $300. This applies even for small sections of roof, due to setup, travel, and equipment costs.
Multi-Service Packages
Bundled services, including gutter cleaning, siding washing, or driveway cleaning, can offer savings. Expect discounts of 10–20% for larger combined jobs.

Travel Fees
Some contractors charge a travel fee for jobs outside their typical service area. These usually range from $25 to $75, depending on distance.
Moss And Algae Treatments
Severe fungal or moss growth often requires additional biocide or cleaning solution application. This can increase costs by $100–$300, depending on infestation level and roof size.
Roof Repairs And Damage
Pre-existing damage, loose shingles, or leaks must be repaired before cleaning, adding further costs (commonly $150–$500). Reputable professionals will inspect for such issues prior to starting the job.
How Often Should You Pressure Wash Or Soft Wash Your Roof?
Roof cleaning frequency varies by region, weather, and roof type. In humid or shaded areas prone to moss and algae, cleaning every 1–3 years is common. In dry or open exposures, cleanings every 4–5 years may suffice. Excessive washing can shorten roof life, so consult your roofer and manufacturer’s warranty before scheduling.
Can You DIY Pressure Wash Your Roof?
DIY pressure washing can be dangerous and may void your roof warranty. Homeowners who lack professional equipment or experience risk causing shingle damage, leaks, or injury. Professional roof cleaning companies have the correct nozzles, detergents, and safety gear, ultimately saving time and risk.
If you attempt a DIY job, always use a soft-wash system, avoid high ladders during wet conditions, and use non-corrosive cleaning solutions recommended for your specific roof type.
What To Look For In A Professional Roof Cleaning Service
- Check References: Select a contractor with good online reviews and a portfolio of successful jobs.
- Insurance & Licensing: Insist on proof of liability insurance and applicable business licensing to protect yourself.
- Safety Compliance: Confirm the crew uses fall-protection equipment and observes OSHA or local safety protocols.
- Written Estimates: Secure a detailed, written quote outlining service, materials, insurance, and timeline.
- Warranty: Reputable companies offer a workmanship or moss regrowth warranty for at least six months.
Risks Of Incorrect Roof Pressure Washing
While “pressure washing” is a common search term, improper cleaning can cause substantial roof damage. Wrong water pressure, harsh chemicals, or poor technique can result in:
- Shingle loss or granule removal, reducing roof lifespan
- Water leaks and moisture damage in attic spaces
- Voided manufacturer warranties on shingles or tiles
- Growth of mold or mildew underneath roofing materials
That’s why experienced professionals default to soft washing with gentle detergents rather than traditional high-pressure washing.
Eco-Friendly And Regulatory Considerations
Environmental regulations increasingly restrict certain chemicals and runoff from roof cleaning. Many states now require eco-friendly or biodegradable cleaning solutions and the use of runoff capture systems, especially near waterways or storm drains. Confirm your chosen service provider complies with all local ordinances and environmental guidelines.
Frequently Asked Questions About Pressure Washing Roofs
Is Pressure Washing Safe For All Roof Types?
No—high-pressure washing can damage most roofing materials. Soft washing is recommended for most residential roofs, including asphalt, tile, and wood. Pressure washing may be suitable for certain metal or concrete surfaces, with proper technique.
How Long Does Roof Cleaning Take?
Most residential roof cleaning jobs are completed in 2–5 hours. Large or complex roofs may require a full day and additional setup time for safety and harnessing.
Should Gutters Be Cleaned At The Same Time?
Yes—cleaning gutters during roof washing ensures proper drainage and prevents future growth of moss or algae. Many contractors provide package deals for both services.
Can Roof Pressure Washing Be Done In Any Season?
Roof washing is typically performed in spring, summer, or fall. Freezing temperatures may reduce cleaning efficacy and create safety hazards. Avoid cleaning on rainy or windy days.
How Can I Keep My Roof Clean Longer?
