How Much Does Roof Pressure Cleaning Cost?

Before hiring a roof cleaning service, it’s essential to understand the costs involved. Roof pressure cleaning is an effective method for removing dirt, moss, and algae, helping to extend your roof’s lifespan. But how much does it cost?

According to industry experts, low-pressure roof washing typically ranges from $0.30 to $0.70 per square foot, making it ideal for many types of roofs, especially shingles.

Here’s a breakdown of what you can expect based on different roof materials:

  • Asphalt Roofs: $150 to $450 for a full cleaning.
  • Cedar Shingles: $600 to $1,100 due to the delicate nature of the material.
  • Rubber Roofs: $450 to $840, typically using a chemical wash.

In the following sections, we’ll dive deeper into how roof pressure cleaning costs are determined and how you can ensure you’re getting the best deal. Let’s get started!


Your Roof Cleaning Budget: What to Expect

Your Roof Cleaning Budget: What to Expect

Roof cleaning is essential for maintaining your property’s longevity and curb appeal. On average, roof cleaning costs $457, but depending on the method, size, and material, prices can range significantly:

  • Low-end cleaning: Around $150.
  • High-end service: Up to $1,000.

Here’s a breakdown by cleaning method:

  • Soft Wash (for asphalt, clay, and concrete roofs): $560 to $900.
  • Chemical Wash (for tar, gravel, or rubber roofs): $450 to $840.
  • Low-Pressure Wash (for wood or slate roofs): $600 to $1,100.
  • High-Pressure Wash (for metal roofs): $350 to $700.

The size of your roof is a crucial factor in determining the cost:

  • 750 sq. ft. roof: $150 to $450.
  • 1,000 sq. ft. roof: $200 to $600.
  • 1,250 sq. ft. roof: Up to $750.

Factors That Shape Roof Cleaning Costs

Roof cleaning isn’t just about washing off grime. Many hidden elements impact the cost. Here are some of the key factors:

Number of Stories

The more stories your home has, the more complex the cleaning process becomes. Cleaning a two-story home will cost more due to the increased risk and difficulty. Expect to pay about $0.10 more per square foot for multi-story homes.

Labor Costs

Labor costs can vary depending on your location, with rates ranging from $17 to $35 an hour. Geographic differences and inflation can drive these costs up.

Extra Services

Roof cleaning services often come with add-ons like moss removal, gutter cleaning, or even roof repairs. While these extras will increase the cost, they can also help maintain your roof’s longevity. Here’s what to expect:

  • Gutter Cleaning: $115–$450
  • Moss Removal: $135–$300
  • Roof Repair: $1,000–$4,500
  • Solar Panel Washing: $150–$350

Roof Coating: A Preventative Step

After cleaning, some homeowners opt to coat their roofs for extra protection. Roof coatings can prevent moss regrowth and extend the lifespan of the roof, much like putting sunscreen on your house. Coating prices vary:

  • Basic Sealants: $0.05 per square foot.
  • Zinc Strips (for moss prevention): Up to $5 per square foot.

DIY vs. Hiring a Professional: Which Is Right for You?

Thinking of cleaning your roof yourself? Here’s a quick comparison:

DIY Roof Cleaning

  • Cost: $150–$600
  • Pros: Can save money upfront.
  • Cons: Requires equipment, time, and effort; increased risk of injury or damage.

Hiring a Professional

  • Cost: $350–$1,100
  • Pros: Professionals bring all the equipment and ensure safety; they often offer warranties and insurance for peace of mind.
  • Cons: Higher cost but more reliable and thorough.

Tip: While DIY might seem cheaper, mistakes can lead to costly repairs. Hiring a pro ensures your roof is cleaned properly and safely, with potential problems spotted early.


How to Save on Roof Cleaning: 5 Smart Ways

Looking to cut costs without compromising on quality? Here are some smart strategies:

  • Plan Preventive Cleanings
    • Scheduling regular cleanings before your roof becomes too dirty can reduce the overall cost. Think of it like regular maintenance for your car—small costs now prevent bigger expenses later.
  • Consider Alternative Cleaning Methods
    • Instead of high-pressure washing, ask your contractor about softer techniques or eco-friendly cleaning solutions. They’re often just as effective and can be more cost-efficient.
  • Bundle Services
    • If you need gutter cleaning or moss removal, ask for a bundled deal. Many companies offer discounted rates for combined services.
  • Schedule During Off-Peak Seasons
    • Booking roof cleaning in the off-season (typically winter or early spring) can result in lower prices since demand is lower.
  • DIY Maintenance Between Professional Cleanings
    • While you may not want to tackle a full roof cleaning yourself, light maintenance like sweeping off leaves or removing small debris can prolong the time between professional cleanings.
