What Is Included in a Roof Cleaning
- Protecting plants and landscaping around the house
- Applying a roof-safe cleaning solution that kills algae, mildew, and moss at the root
- Letting the solution work, then rinsing at low pressure
- Rinsing landscaping and cleaning up afterward
What Changes the Price
- Roof size: more square footage means more solution and more time.
- Pitch and height: steep and two-story roofs need more setup and safety work.
- Amount of growth: heavy algae or thick moss can need a stronger treatment or a second pass.
- Roof material: asphalt shingles and concrete or clay tile are cleaned differently. See tile roof cleaning.
- Access: trees, tight side yards, and delicate landscaping add time.
Soft Wash vs. Power Washing a Roof: Why It Matters for Cost
People often search for “power wash roof cost” or “pressure wash roof cost.” We do not pressure wash shingle roofs. High pressure can strip the protective granules off asphalt shingles and push water under them, which can shorten the life of the roof. A soft wash uses low pressure and a cleaning solution instead, so the price you pay is for a cleaning that protects the roof. Learn more in what is soft wash roof cleaning.
Roof Algae Treatment Cost
Algae treatment is part of a soft wash roof cleaning, not a separate service. The black streaks on most North Texas roofs are algae, and the cleaning solution is what kills it. See why roofs get black streaks.
Moss Removal
Moss is thicker than algae and grows in clumps on shaded roofs. It is treated during the cleaning, and heavy moss can take longer to release. See how to remove moss from a roof.
How Long Do Results Last?
Because a soft wash kills growth at the root, results usually last much longer than a simple rinse. Shaded roofs and roofs under trees may need treatment more often.
Is Roof Cleaning Worth It?
For most homeowners, yes. It improves curb appeal, removes growth that holds moisture on the roof, and costs a small fraction of a roof replacement. It is also a common step before selling a home or installing solar panels.
Save by Bundling
Many homeowners clean the roof and gutters in the same visit. See roof and gutter cleaning and our packages.

FAQs
How much does roof cleaning cost?
In the Dallas-Fort Worth area, most roof cleaning jobs cost $750 to $1,050 ($0.30 to $0.35 per sq ft), depending on the roof’s size, pitch, material, and how much algae or moss is present.
How much does it cost to power wash a roof?

Is roof algae treatment extra?
No. Killing the algae is the main purpose of a soft wash roof cleaning, so it is included in the price.
Is roof cleaning cheaper than replacing a roof?
Yes. Roof cleaning costs a small fraction of a replacement and removes the growth that makes a roof look old.
For the roofing industry’s take on algae streaks, see Algae Discoloration of Roofs from the Asphalt Roofing Manufacturers Association.
Can I save by cleaning my roof and gutters together?
Often yes. Booking both in one visit saves setup time, and our packages offer a multi-service combo for two or more services.
Roof Washing Cost vs. Pressure Washing a Roof
Homeowners search for this service under several names — roof washing cost, roof soft wash cost, or the cost to pressure wash a roof — but in DFW they all point to the same job. A professional roof is cleaned with a low-pressure soft wash, never a pressure washer, so the real roof washing cost is the $750 to $1,050 soft wash range above. If a company quotes a low price to power wash a roof, treat it as a red flag: high pressure strips shingle granules and can void the roof warranty. How much to soft wash a roof comes down to its size, pitch, and how far the algae has spread.
