Roof Washing in Austin, TX
Estimates are calculated from this rate. Final pricing can vary with property condition, staining, surface type, and access.
Those black streaks on Austin roofs are not dirt. They are Gloeocapsa Magma, a hardy algae that feeds on the limestone filler in asphalt shingles and spreads fast in our heat and humidity. Hi-Tech Power Wash soft washes roofs to kill the algae at the root, restoring your roof's appearance without the high pressure that strips granules and shortens shingle life.
Never let anyone pressure wash your roof
High pressure strips the protective granules off asphalt shingles, which shortens the life of the roof and is the kind of damage roofing manufacturers warn against. Soft washing avoids that entirely. We apply a low-pressure treatment that breaks down the algae, then let time and rain rinse it. The streaks fade over the following weeks and the growth is slowed at the root rather than smeared around.
Commercial TPO roof cleaning in Austin
TPO (thermoplastic polyolefin) is the white membrane on most flat commercial roofs in Austin, and its reflective surface is the whole point of it. Dirt, dust, airborne pollutants, organic growth and general environmental buildup dull that surface over time. Cleaning restores the roof's clean, reflective appearance and works well as part of a commercial roof maintenance program. The method matters more here than on a shingle roof: aggressive high pressure can damage the membrane or compromise the seams, so we use controlled, low-pressure cleaning and professional cleaning solutions selected for the roofing material and its condition.
- Restaurants, retail properties, office buildings, warehouses, multi-family and other commercial facilities
- Controlled low pressure, chosen to protect the membrane and its seams
- One-time cleaning or a routine maintenance schedule, whichever suits the property
- Quoted after we evaluate roof size, condition, buildup, access, drainage, safety requirements and overall scope, rather than by the square foot rate above

Frequently asked questions
How much does roof washing cost in Austin?
Roof soft washing is $0.35 per square foot of roof area, so a 2,000 sq ft roof is around $700. Steep pitches, height, and access can affect the final number, which we confirm before starting. Minimum service charge is $250 per visit.
Why does my Austin roof have black streaks?
Black streaks are caused by Gloeocapsa Magma algae that feeds on the limestone granules in shingles. Austin's heat and humidity make it spread quickly. Soft washing kills it at the root so it stays gone for years.
Is soft washing safe for my shingles?
Yes. The damage people associate with roof cleaning comes from high pressure knocking the granules off the shingles. We never put high pressure on a roof. If you want to be certain about your specific warranty terms, check with your roofing manufacturer, and we are happy to describe our method to them.
How often should an Austin roof be cleaned?
Most Austin roofs benefit from a soft wash every two to three years, sooner on north-facing slopes and under heavy tree cover where algae grows fastest.
Is the treatment safe for my plants and gutters?
Yes. We protect and pre-wet landscaping, control runoff, and rinse plants after the job so your yard is protected throughout.
Do you clean commercial TPO and flat roofs?
Yes. Commercial TPO roof cleaning is a regular part of our work across Austin and the surrounding area, on restaurants, retail properties, office buildings, warehouses and multi-family properties. TPO is a membrane rather than a hard surface, so we clean it with controlled low pressure and solutions selected for the material, because high pressure can damage the membrane or compromise the seams.
How much does commercial TPO roof cleaning cost in Austin?
It is quoted rather than priced per square foot. The per square foot rate on this page is for residential shingle soft washing. A commercial membrane roof is quoted after we look at roof size, condition, how much buildup there is, access, drainage, safety requirements and the overall scope. We can quote a one-time clean or a recurring maintenance schedule.
