When was the last time you looked up at your roof? If it’s been a while, you might have noticed some unsightly moss, algae, or debris creeping in. Not only does this hurt your home’s curb appeal, but it can also shorten your roof’s lifespan if left unchecked. Professional roof cleaning is a smart investment—but how much does it actually cost? The truth is, roof cleaning prices vary widely based on several factors. Let’s break it down so you can get a clearer picture of what to expect and why it’s worth it.
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.
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.
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.
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.
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.
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.
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.
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.
