How Much Does Roof Cleaning Cost in San Antonio?
A typical professional roof cleaning in San Antonio runs $250 to $800. That range comes from a San Antonio company’s published cost guide, released in May 2026. The same guide says standard one story homes with light black streaking often fall between $300 and $450.
Bigger jobs climb from there. Clay tile, multistory homes, steep pitches and heavy algae can push the price to $750 to $1,000 or higher. National cost guides land in a similar range for an average size roof.
These are market numbers, not our price list. Our own services start at $299, with each roof priced after we look at it. Estimates are free.
How much does roof cleaning cost per square foot?
Most roof cleaners charge by the square foot, so the final price follows the size of the roof. Homewyse is a national cost estimating site. It says the national average cost starts at $0.25 to $0.46 per square foot.
A national home guide shows a wider spread of $0.20 to $0.70, depending on the cleaning method. The same guide puts a 1,500 square foot roof at $300 to $1,050. Its average for a home that size is $675.
Your roof has more square feet than your floor plan. Overhangs and pitch make it a little larger than the home’s listed square footage. Math based on the house size alone will come in low. We price roof cleaning in San Antonio after we look at the roof itself.
What do published roof cleaning prices look like?
Cost guides quote roof cleaning two ways. Some give a rate per square foot, and others give a price for the whole roof.
| Roof or pricing basis | Published range | Source |
|---|---|---|
| National average, per square foot | Starts at $0.25 to $0.46 | Homewyse, September 2026 |
| Soft wash, per square foot | $0.30 to $0.75 | National cost guides |
| 1,500 square foot roof, typical | $300 to $1,050 | National home guide |
| National average range, whole roof | $450 to $700 | National cost guide |
| Soft wash, whole roof | $510 to $1,275 | National cost guide |
| Typical roof, San Antonio | $250 to $800 | San Antonio company’s guide |
| One story, light streaking, San Antonio | $300 to $450 | San Antonio company’s guide |
| Clay tile, multistory, steep pitch, heavy algae, San Antonio | $750 to $1,000 or higher | San Antonio company’s guide |
Each row is a published market figure, not our price list. The spread is wide because roofs differ in size and condition. The method moves the rate too, which is why the soft wash rows run higher.
What changes the price of roof cleaning in San Antonio?
Roof size sets the base price. These details move it up or down from there.
Pitch. A steep roof needs extra safety equipment. One national guide says that adds up to $0.15 per square foot.
Stories. The roof on a taller home is harder to reach. National guides add about $0.10 per square foot once a home has more than one story.
Shingle or tile. One national guide gives asphalt shingle, clay tile and concrete tile the same soft wash rate, $0.30 to $0.75 per square foot. Locally, the San Antonio guide names clay tile among the jobs that can reach $750 to $1,000 or higher.
Metal. One national guide lists metal panels lower, at $0.20 to $0.60 per square foot. That figure is priced for a pressure wash.
Streaking. Light streaks make for a lighter job, and thick growth takes longer. The San Antonio guide prices the two far apart. Our guide to what causes black streaks on a roof covers the algae itself.
Access. Tall live oaks over the roof and narrow side yards slow the setup. A roof with open access takes less time.
Gutters. Debris from the roof ends up in the gutters. One national guide tells homeowners to budget for add-ons like gutter cleaning. Booking gutter cleaning on the same visit handles both in one trip.
These factors stack. A steep two story roof with heavy streaking sits well above a low one story roof with light growth.
Why do roofs get soft washed instead of pressure washed?
We clean roofs with the soft wash method. It pairs low pressure water with cleaning solutions that kill mold, mildew and algae at the root. High pressure is never used on a shingle roof.
Cost guides back that up. One warns against pressure washing asphalt shingles, since it can strip away the protective granules. It adds that the damage can shorten the life of the roof. Another notes that cleaning too hard can crack roof tiles.
A roof soft wash does cost more than other methods. In national guides it is the priciest method, at $0.30 to $0.75 per square foot. For a whole roof, one guide lists $510 to $1,275.
How often does a roof need cleaning?
One national guide says cleaning every 2 to 3 years is enough for most homes. It suggests yearly cleaning in humid areas, where mold and algae grow faster. Under heavy tree cover, it suggests every 1 to 2 years.
Those intervals are rules of thumb. Roofs that sit under heavy shade tend to land on the shorter end.
Can you clean your own roof to save money?
One national guide says homes with steep roofs or more than one story are better off hiring a professional. It also says blasting a roof with a pressure washer is never the right choice.
Roof work means working at height on a sloped, wet surface. A cleaning mistake can also cost more than the job, since stripped granules and cracked tiles mean repairs.
How do you get a real price for your roof?
A published range cannot see your roof. Its size, pitch, material and growth decide the real number.
