Professional Roof Cleaning in New York: Restore Your Roof and Protect Your Home
NYC's climate — humid summers, freezing winters, and salty coastal air — makes roofs uniquely vulnerable to algae, moss, and mildew. Low-pressure soft-wash roof cleaning extends shingle lifespan, improves energy efficiency, and protects your home's biggest investment.
Why Roof Cleaning Matters in New York
- Prevent roof damage from algae and moss eating into shingles
- Increase energy efficiency — clean roofs reflect heat better
- Enhance curb appeal and property value
- Health benefits — eliminates mold and mildew that affect indoor air
Signs You Need Professional Roof Cleaning
- Black streaks (Gloeocapsa Magma algae)
- Visible moss growth between shingles
- Mildew patches on shaded north-facing slopes
- Debris accumulation in valleys and around chimneys
Our Roof Cleaning Process
Inspection & Safety Setup
We inspect for damaged shingles, set up harnesses, and protect surrounding landscape with tarps.
Apply Biocidal Solution
Low-pressure application of a manufacturer-approved soft-wash mix that kills algae, moss, and mildew at the root.
Dwell Time
Solution sits for 15–30 minutes — long enough to penetrate but never to dry on the surface.
Gentle Rinse
Low-pressure rinse from ridge to gutter. No high-PSI water touches the shingles.
Final Walkthrough
Inspect for missed spots, clean gutters, and document the job with before/after photos.
Prices vary based on surface, location, and size. Free on-site estimates available.

Common Mistakes to Avoid
- Pressure washing shingles — voids warranty and spreads algae
- Using chlorine bleach without neutralizer — kills surrounding plants
- Cleaning in summer heat — solution dries before penetrating
- Walking on wet shingles — extremely dangerous without harnesses
