How Much Does Roof Cleaning Cost? Breaking Down the Pricing Factors

1. The Size of Your Roof

It’s no surprise that the bigger your roof, the more it’ll cost to clean. Roof cleaning companies typically charge by the square foot, with prices often ranging from $0.20 to $0.70 per square foot. For a standard 2,000-square-foot roof, you’re looking at anywhere between $400 and $1,400. Smaller roofs, like those on a single-story home, will naturally fall on the lower end, while sprawling multi-level homes might push the price higher.

2. Roof Material and Condition

Not all roofs are created equal. Asphalt shingles are pretty straightforward to clean, but materials like slate, tile, or metal might require special techniques or equipment, bumping up the cost. If your roof is in rough shape—think heavy moss growth, stubborn algae stains, or piles of leaves—the cleaning crew might need extra time or stronger solutions, which can add to the bill. Regular maintenance keeps costs down, while neglect can make the job pricier.

3. Pitch and Accessibility

A steep roof is trickier (and riskier) to clean than a flat one. If your roof has a sharp pitch or hard-to-reach spots, expect to pay a bit more—sometimes an additional $100 to $300—for the extra effort and safety gear required. Accessibility matters too. If your home is tucked behind trees or has limited ladder access, that could tack on a small fee as well.

4. Location, Location, Location

Where you live plays a big role in pricing. In urban areas with a higher cost of living, roof cleaning might run $500 to $1,000 for an average job, while rural areas could be closer to $300 to $600. Local weather matters too—humid climates prone to moss or algae often see higher demand for cleaning, which can influence rates.

5. Cleaning Method

There’s more than one way to clean a roof, and the method impacts the price:

Pressure Washing: Fast and effective for tough grime, but not always safe for delicate shingles. Costs typically range from $300 to $800.

Soft Washing: Uses low-pressure water and eco-friendly chemicals to gently remove stains. This tends to be pricier, often $400 to $1,000, but it’s safer for most roofs.

Manual Cleaning: For small jobs or spot treatments, pros might scrub by hand, starting at $200 to $500.

Each method has its pros and cons, and a good contractor will recommend what’s best for your roof.

6. Add-On Services

Thinking of bundling in extras? Gutter cleaning, skylight washing, or moss prevention treatments can add $50 to $200+ to your total. These upsells can save you money in the long run by keeping your roof in top shape, but they’ll increase the upfront cost.

Why Pricing Varies So Much

With all these factors in play, it’s easy to see why roof cleaning doesn’t have a one-size-fits-all price tag. A small, flat roof in a rural area might only set you back $300, while a large, steep roof with tile shingles in a big city could climb past $1,500. The good news? Professional cleaning is still a fraction of the cost of a roof replacement, which can easily hit $10,000 or more.

Is Roof Cleaning Worth the Cost?

Absolutely. Beyond boosting your home’s appearance, regular cleaning prevents damage from moss, algae, and debris buildup. It can extend your roof’s life by years, saving you from expensive repairs down the road. Plus, a clean roof can even improve energy efficiency by reflecting more sunlight instead of absorbing heat through dark stains.
