Roof Cleaning in Kingston, NY | Black Streak & Moss Removal
Certified Soft-Wash Roof Cleaning That Protects Your Shingles
Freedom Powerwash specializes in professional roof cleaning designed to safely restore and protect asphalt shingles from destructive organic growth common throughout the Hudson Valley. We use the certified Soft-Wash method, a zero-pressure, detergent-based cleaning system that completely eliminates black streaks caused by Gloeocapsa magma, along with moss and lichen that actively degrade roofing materials. These organisms feed on the limestone filler within shingles, trap moisture, and accelerate roof deterioration while reducing energy efficiency. Our Soft-Wash approach removes this growth at the root without damaging shingles, preserving both the appearance and lifespan of your roof.

What Is the Best Way to Clean a Roof?
The safest and most effective way to clean a roof is with professional soft washing. This method uses low pressure and a controlled cleaning solution to kill algae, moss, and lichen without damaging your shingles. High-pressure washing should never be used on roofing because it strips granules, voids warranties, and shortens the life of your roof.
Freedom Powerwash follows the manufacturer-approved soft-wash process that protects your home and delivers long-lasting results.
Property & Plant Protection
We begin by wetting plants, protecting landscaping, and shielding delicate areas to keep your property safe through the entire cleaning.
Low-Pressure Soft-Wash Application
We apply a biodegradable roof-cleaning mix that kills black streak algae, moss, and lichen at the root. This stops the growth instead of just removing the top layer.
No Brushing or Scraping (Optional Add-On)
Other companies brush or scrape roofs to get fast visual results, but this removes shingle granules and causes early deterioration.
We never include brushing or scraping in a standard roof cleaning because it shortens roof life. However, for very heavy moss or thick algae, light agitation can be added for an additional cost. Even then, chemistry is always the safest and preferred method.What to Expect After Treatment
Soft washing cleans in stages:
- Black streaks lift right away and continue clearing over the next 24–48 hours.
- Moss and lichen turn white or yellow as they die, then begin breaking down over 3–6 weeks as the roots release.
- Thicker growth may take 6–8 weeks depending on shade, moisture, and roof age. This slow release is completely normal and shows the treatment is working correctly.
Second Treatment (If Needed)
If stubborn patches remain, we may recommend a discounted second treatment. This helps finish off any deep-rooted growth without risking damage to your shingles.
Final Rinse & Property Check
We flush landscaping, rinse gutters, and walk the property to make sure everything is clean, even, and safe.
Soft washing is the safest and most effective way to clean roofs in Kingston and the Hudson Valley, giving your home long-lasting protection without risking shingle damage.
The Danger of High-Pressure Washing Your Roof
High-pressure washing should never be used on asphalt roofing. Traditional pressure washing strips away the protective ceramic granules embedded in your shingles. These granules are critical for reflecting heat, protecting the asphalt layer, and maintaining manufacturer warranties. Once granules are lost, shingles age rapidly, become brittle, and are more susceptible to wind, ice, and UV damage. Our Soft-Wash method uses no damaging pressure, making it the safest and most effective option for roof cleaning. The Soft-Wash approach aligns with recommendations from major roofing manufacturers and industry best practices, making it the preferred method for maintaining asphalt shingle roofs without voiding warranties.
Common Roof Issues We Resolve
Black Streaks (Gloeocapsa magma): A moisture-holding cyanobacteria that causes dark discoloration and feeds on roofing materials. We eliminate it at the root level.
Moss and Lichen Growth: These organisms develop root-like structures beneath shingles, lifting edges and creating vulnerability to wind, ice, and water intrusion.
Reduced Curb Appeal: Professional roof cleaning restores your roof’s original color and appearance, dramatically improving the overall look and value of your home.
Safe for All Common Roofing Types
Asphalt shingles (most common)
Architectural and dimensional shingles
Cedar shake roofs (using specialized solutions and dwell times)
Tile and slate roofing systems
Each roof is evaluated individually to ensure the correct solution strength and application method are used.
Guaranteed Results You Can Trust
Because we kill the organic growth instead of simply rinsing it away, our results last. Every roof cleaning service is backed by our extended 24-Month Black Streak Free Guarantee. If black streaks caused by organic growth return within two years of service, we will return and retreat the affected areas at no additional cost. This guarantee reflects our commitment to safe workmanship, professional standards, and long-term protection of your home’s most valuable asset.

Frequently Asked Questions
We answer the most common questions Hudson Valley homeowners ask us.
Is Soft Washing safe for asphalt shingles?
Yes. Soft-Wash roof cleaning is the safest method for asphalt shingles because it uses zero damaging pressure. Instead of blasting the roof, we apply a specialized solution that removes organic growth without stripping protective granules.
Will roof cleaning remove black streaks completely?
Yes. Our Soft-Wash process is designed to eliminate black streaks caused by Gloeocapsa magma by killing the organism at the root. This is why our results last longer than surface-only cleaning methods.
How often should a roof be cleaned in the Hudson Valley?
Most homeowners benefit from roof cleaning every 2 to 4 years, depending on tree cover, shade, and moisture levels. Homes surrounded by trees or heavy shade may need service more frequently.
Can pressure washing damage a roof?
Yes. High pressure can remove the protective granules on shingles, shorten roof life, and potentially void manufacturer warranties. That is why we never use high pressure on asphalt roofing.
Do you clean moss and lichen off roofs?
Yes. Our Soft-Wash process targets moss and lichen growth and helps prevent it from returning by eliminating the organisms that allow it to spread across the roof surface.
