Quick answer
Professional roof cleaning in Austin usually runs $899 to $1,499 for a soft-wash treatment backed by a two-year results guarantee. Your final price depends on the roof’s material, size, pitch, and how heavy the algae or moss buildup is. Below, we break down exactly what goes into that number.
If you have searched roof cleaning prices in Austin, you have probably seen quotes swing from under $300 to well over $1,000. That gap is confusing, and it is fair to wonder which number to trust.
Those humid Central Texas summers are why so many local roofs need attention. The black streaks spreading across shingles are a hardy algae called Gloeocapsa magma, and it thrives on north-facing slopes and under the live oak and cedar canopy common across the metro. We soft wash every roof to remove it, never high pressure.
How Much Does Roof Cleaning Cost in Austin?
Our Austin roof cleaning service starts at $899 and tops out around $1,499 for most homes. That range covers a full soft-wash treatment, the labor and insurance behind it, and a two-year results guarantee.
National price guides land lower because they average every roof in the country, including small single-story homes cleaned without a guarantee or full insurance. They are useful for context, not as a stand-in for a real Austin quote. Here is how the numbers compare.
Those national figures come from published cost data at HomeGuide, and soft washing sits at the higher end per square foot because it is the most careful and labor-intensive approach.
Most homeowners want a per-job number rather than a per-square-foot rate, which is how we quote. We would rather see your roof in person, or from clear photos for a straightforward job, and give you a real figure instead of a vague “starting at” price.
What Determines Your Roof Cleaning Price
Five things move the price within that range, and they are the same factors we weigh when we quote your roof.
Roof material. Asphalt shingle is the most common roof we clean and the most straightforward. Tile, including the clay and Spanish tile you see on plenty of Austin homes, needs a more careful hand. Metal sits in between. We clean all three.
Size. A larger roof takes more solution and more time to treat, so the square footage of the surface itself is one of the biggest drivers of the final number.
Pitch and how we reach it. A walkable roof is faster and safer to clean than a steep one we have to treat from a ladder. The steep hill-country rooflines around Westlake, Lakeway, and Barton Creek often fall into the ladder category, which adds to the job.
Number of stories. Two-story and taller homes need more equipment and setup to reach safely, and that shows up in the price.
Contamination level. Light algae streaking rinses cleaner than heavy moss or lichen, which needs more algaecide and repeat passes to fully kill and lift.
| Factor | Lower cost | Higher cost |
|---|---|---|
| Material | Asphalt shingle | Tile, heavy metal detail |
| Size | Small single-story | Large footprint |
| Pitch and access | Walkable | Steep, ladder-sprayed only |
| Stories | One story | Two or more stories |
| Contamination | Light algae streaks | Heavy moss or lichen, repeat passes |
Soft Washing vs. Pressure Washing, and Why It Matters for Cost and Warranty
We soft wash every roof. That means a low-pressure application of a diluted sodium hypochlorite solution, our algaecide, that kills algae down to the root, including the spore layer that plain water pressure can never reach. Then we rinse at low pressure and let the roof dry clean. It is the same reason we soft wash every house we touch.
High pressure works against you here. Blasting a shingle or tile roof at 1,300 to 2,800 psi strips the protective granules, shortens the roof’s life, and can void your manufacturer warranty, as This Old House notes in its roof-cleaning guide. That is not just our opinion. The Asphalt Roofing Manufacturers Association and the Roof Cleaning Institute of America both advise against pressure washing shingle and tile roofs, and major shingle makers echo the same low-pressure, sodium-hypochlorite guidance.
Why Some Quotes Are $300 and Ours Start at $899
A $275 to $400 roof cleaning is real, but it usually leaves things out. Often that means no proper insurance, a rinse that makes algae disappear for a few weeks instead of chemistry that kills it at the root, no guarantee if it comes back, and no single person accountable for the result.
We are owner-operated, so the person who quotes your roof is the person who cleans it. We back roof cleaning results for two years, and we are rated 4.9 stars across 200+ Google reviews. The higher number buys a job done once, correctly, by someone who stands behind it.
Our pricing is fair and upfront, and it reflects what a lasting, insured clean actually costs.
The Cost of Not Cleaning Your Roof
Algae does structural damage, not just cosmetic. It feeds on the limestone filler in asphalt shingles, which speeds up granule loss and wears the roof down faster than it should. Left alone for years, that buildup can shorten a roof’s usable life, and a cleaning costs a small fraction of a full replacement.
There is a comfort cost too. A darkened, algae-covered roof absorbs more heat, which can nudge up cooling bills during an Austin summer. For anyone selling, streaks are a red flag buyers and inspectors notice immediately.
Many Austin-area HOAs also cite homeowners for visibly streaked or stained roofs. Algae spreads roof to roof across a subdivision, so a clean roof keeps you compliant and keeps the whole street looking consistent.
How Often Should You Clean Your Roof in Austin?
Most Austin roofs do well with a cleaning every one to three years. Homes under heavy tree canopy or with north-facing, shaded slopes run on the shorter end, sometimes closer to annually, because those roofs hold moisture and grow algae faster.
Our two-year results guarantee gives you a clear window before the roof needs attention again. We would rather set that expectation honestly than promise a clean that lasts forever, because no roof treatment does.
If you are already thinking about the rest of your exterior, our soft-wash house washing runs on its own recommended rhythm of every six months to a year, and the two services pair well on a single visit.
Frequently Asked Questions
Do you have to get on the roof to clean it?
It depends on the pitch. We clean from the ground when a roof is too steep to walk safely, and from the roof when it is walkable. The low-pressure soft-wash method is the same either way.
Will roof cleaning hurt my plants or pets?
We saturate landscaping with water before, during, and after the job, and the solution we use breaks down quickly. We ask that pets stay inside while we work and off the cleaned areas for about 24 hours, since some of the solution can stay active while it is still wet.
Will you clean a damaged roof?
No. If a roof already has damage, we will not clean it until it is safe to do so. Soft washing is maintenance, not a substitute for a repair.
How long does a professional roof cleaning take?
Most residential roofs take one to two hours, depending on size, pitch, and how heavy the buildup is.
Can I clean the roof myself instead of hiring a pro?
You can, but the risk rarely pays off. Walking a wet, sloped roof is dangerous, and store-bought pressure equipment strips granules fast. A professional soft wash reaches the algae at the root and keeps you off the ladder.
