Roof cleaning costs about $300 to $900 for a typical single-story home, or roughly $0.20 to $0.60 per square foot. Larger homes, steep pitches, and heavy moss or black algae streaking push the price past $1,000. Most of the cost is labor and safety, not chemicals.
We build websites and SEO for pressure washing and exterior cleaning companies, and we run our own home-service companies. Here's what changes the price, why soft washing matters, and when you can skip the service entirely.
Low pitch, light algae, easy access. A straightforward soft wash that a two-person crew handles in a couple of hours.
Moderate size and pitch with visible streaking or some moss. The bulk of residential jobs land here.
Heavy moss, tall multi-story homes, or pitches that need fall protection and harnesses. Safety setup is most of the added cost.
This distinction protects your roof, so it's worth knowing before you book:
If a quote is much cheaper than the rest, ask whether they soft wash. A pressure wash can shorten your roof's life and cost far more than it saved.
A clean roof is mostly cosmetic, so it isn't always worth the spend. Hold off if:
Do pay for it when moss is actively lifting shingles, when you're preparing to sell, or when the roof is steep or two stories. Moss that holds moisture can shorten a roof's life, so removing it can be genuine maintenance, not just curb appeal.

For asphalt and most residential roofs, yes. It kills algae and moss without stripping shingle granules the way high pressure can. Reputable companies soft wash roofs.
Every two to five years in most climates, sooner in humid, shaded, or coastal areas where moss and algae grow fast. A roof with no shade may go much longer.
Not when done by soft wash. Damage comes from high pressure, which can blast off the granules that protect the shingle. Confirm the method before booking.
