How much does roof cleaning cost?
Roof cleaning cost has no single fixed number. We looked for a company that posts a price the way a supplier posts a material list, and found one: Southeast Softwash posts sight-unseen minimums by story count and square footage, not a flat rate. Every other real company quotes only after a free on-site look. The job is tied to your roof, not a catalog item.
Why doesn’t anyone publish one?
A cubic yard of concrete is the same yard in Ohio or Oregon, so a producer can print one number. A roof is not. Material, pitch, story height, and staining change what a crew has to do. The liability of working at height means most companies will not price it sight unseen. A page quoting a flat per-square-foot rate is repeating a number with no roof attached to it.
What actually drives your roof cleaning cost?
Even without a published number, here is what moves the price and what every crew accounts for.
| Factor | Why it moves the price | Ask your quote about it |
|---|---|---|
| Roof material | Shingle, tile, metal, wood shake, and slate tolerate chemistry and pressure differently. | Which method fits your material. |
| Pitch and story height | Steeper or taller roofs need more rigging and time. | Whether height carries a separate line. |
| Staining severity | Light streaking clears faster than years of moss and lichen. | Expected passes or dwell time. |
| Cleaning method | Soft washing costs more than a rinse, but it is the method that does not void a shingle warranty. | Soft wash versus pressure wash. |

Should your roof be pressure washed or soft washed?
ARMA states plainly: never pressure wash an asphalt shingle roof. It causes granule loss and very likely premature failure. Its recommended method is a soft wash, a fifty-fifty mix of laundry-strength bleach and water, sprayed on. It dwells fifteen to twenty minutes, then rinses at low pressure. That dwell time is part of what a soft wash job bills for. A crew pressure washing your shingles is cutting a corner ARMA warns against.
What does the crew cost per hour?
Roofers earn a $27.95 national mean hourly wage and a $26.65 median, per BLS OEWS national estimates for May 2025. That is a single source, so treat it as a floor. It covers a roofer’s wages only, not a soft wash company’s full bill. Our contractor hourly labor rates by trade page breaks out the same BLS data for every trade.
How do you get a roof cleaning cost you can trust?
-
Get three on-site quotes
Skip a quote given over the phone or from a photo alone. A real crew wants to see the pitch, access, and staining in person.
-
Ask soft wash or pressure wash, and why
A company offering pressure washing on shingles should explain why. A confident soft wash answer is a good sign.
-
Break each quote into three lines
Chemical and materials, labor, and access equipment. A lump sum hides which company is actually cheaper once the lines match up.
-
Turn the number into an estimate
Once you have a real quote, build it into an editable line-item estimate. Send it, adjust it, and keep it on file.

Frequently asked questions about roof cleaning
The price
How much does roof cleaning cost?
Almost no fixed roof cleaning cost is posted by a live publisher. Southeast Softwash posts a sight-unseen minimum starting at $350, but still finalizes the price on site. Most real companies quote only after that on-site look, not from a posted price list.
Why do roof cleaning companies not post a price online?
Because the job is not a standard unit. A cubic yard of concrete is the same everywhere; a roof is not. Material, pitch, access, and staining change what a crew has to do, so companies price after seeing the roof.
The method
Should I pressure wash or soft wash my roof?
Soft wash it, especially if it is asphalt shingle. ARMA states that pressure washing an asphalt shingle roof causes granule loss and very likely premature failure. Its recommended method is bleach and water, left to dwell, then rinsed at low pressure.
How much do roofers earn per hour?
A $27.95 national mean and $26.65 median hourly wage, per BLS OEWS national estimates for May 2025. That covers a roofer’s wages only, not a soft wash company’s full bill.
Estimating the job
Can I measure my roof for a cleaning quote with my phone camera instead of a tape?
Get the square footage from your roofing records or the crew doing the on-site quote. Exterior roof measurement is not a phone camera task. Once you have that number, SimplyWise Cost Estimator turns a job-site photo into an itemized estimate in about 6 seconds. The LiDAR room scan on a Pro iPhone covers interior rooms, not the roof.
Does SimplyWise Cost Estimator build a roof cleaning quote?
It builds material, labor, and fee line items with unit, quantity, and price per unit. Enter your accepted quote’s numbers, then send a branded quote the client signs to approve. Pricing is $29.99/mo or $239.99/yr, with a 7-day free trial.
