Roof Soft Washing
Safe, low-pressure roof washing that removes moss, algae, and black streaks without damaging your shingles.
Extend The Life of Your Roof With Professional Roof Cleaning Services
Black streaks and algae buildup on your roof are not only unsightly but can also shorten the life of your roofing materials. Left untreated, organisms like Gloeocapsa magma feed on your shingles and accelerate deterioration — leading to costly repairs or premature replacement.
Duncan Power Washing provides professional roof soft washing services that safely remove algae, moss, lichen, and organic growth without damaging your shingles. Our low-pressure roof cleaning method is the manufacturer-recommended approach for asphalt shingle roofs, keeping your home looking great and your roof protected.
Why Soft Wash Roof Cleaning?
Our low-pressure soft wash system applies specialized cleaning solutions that break down and eliminate buildup at the source. This process restores the appearance of your roof while helping extend its lifespan.
Soft washing is the recommended cleaning method for asphalt shingle roofs because it effectively cleans without the risks associated with high-pressure washing. Pressure washing a roof can:
- Strip away protective granules from shingles
- Void manufacturer warranties
- Force water under flashing and into your attic
- Cause cracking and premature aging
Our roof washing services use biodegradable solutions that kill algae, moss, and bacteria at the root — so your roof stays cleaner for longer and your warranty stays intact.

FAQs
Find answers to common questions about our roof soft washing services, pricing, and what to expect.
Roof cleaning costs vary based on roof size, pitch, accessibility, and the extent of algae or moss growth. Most residential roof soft washing services range from $300 to $700. Contact Duncan Power Washing for a free estimate specific to your home.
Black streaks are caused by Gloeocapsa magma, a type of blue-green algae that feeds on the limestone filler in asphalt shingles. It thrives in warm, humid environments and spreads across your roof over time. Soft washing safely removes this algae and prevents regrowth.
We recommend roof cleaning every 2 to 4 years, depending on your local climate and tree coverage. Homes surrounded by trees or in humid areas may need more frequent cleaning to prevent algae and moss buildup that shortens roof lifespan.

Pressure washing a roof is not recommended. High-pressure water strips away protective granules from shingles, can void manufacturer warranties, and may force water under flashing. Soft washing is the safe, effective alternative that cleans thoroughly without causing damage.
