Why Roof Washing Matters in Rockland County
The local environment makes regular roof cleaning not optional — but essential.
Shaded lots in Nyack and Tappan promote moss and lichen growth
High humidity along the Hudson accelerates black algae stains in places like Haverstraw and Valley Cottage
Seasonal pollen and leaf buildup in Nanuet and Pearl River lead to streaking and clogged gutters
Freeze-thaw cycles in Hillburn and Montebello cause dirt buildup and organic decay
Discoloration reduces curb appeal and can impact property resale value
Our low-pressure soft wash system kills and removes algae at the root, gently lifting years of staining and buildup while preserving your roof’s integrity.
Soft Wash vs. Pressure Washing – What’s the Difference?
Never let anyone pressure wash your roof in Rockland County.
Pressure washing blasts away shingle granules, breaks protective sealants, and can void your manufacturer warranty. Instead, we use the soft wash method:
| Method | Soft Wash (What We Use) | Pressure Washing (What We Avoid) |
|---|---|---|
| Pressure Level | < 100 PSI | 2,000–3,000 PSI |
| Suitable For | Asphalt, Tile, Metal, Composite | Concrete, Stone, Siding |
| Roof Safety | Excellent | High Risk of Damage |
| Warranty Impact | Warranty-Safe | Often Voids Warranty |
| Cleaning Method | Biodegradable Detergents + Rinse | High-Pressure Blast |

FAQs – Roof Washing in Rockland County
Your Roof Washing Questions Answered:
Most roofs in Rockland should be professionally washed every 2–3 years, especially if you live in wooded areas like Tappan, Montebello, or Hillburn, where shade and moisture accelerate moss, algae, and lichen growth. In high pollen or tree-dense zones like Nanuet and Pearl River, annual rinsing may be beneficial to prevent organic buildup.
Yes — our soft wash roof cleaning method is manufacturer-approved and warranty-safe. We never use high-pressure equipment. Instead, we rely on a proprietary blend of biodegradable detergents and low-pressure rinsing, making it ideal for delicate shingles across Spring Valley, Haverstraw, and New City.
Absolutely. A clean roof restores your home's visual appearance and often adds instant curb appeal for potential buyers. In competitive markets like Nyack or New City, homes with freshly cleaned roofs often appraise better and sell faster. It also signals proactive maintenance to buyers and home inspectors.
Those black streaks are Gloeocapsa magma, a hardy algae that thrives in humid climates like Rockland County. It feeds on limestone filler in asphalt shingles and retains moisture, accelerating deterioration. Our soft wash system kills this algae at the root — helping prevent re-growth for 12–24 months.
Yes — our method gently breaks the moss and lichen bond at the root level. Some moss may flake off instantly; thicker patches will loosen and fall away naturally over the next 7–21 days. For homes in shaded zones like Blauvelt, Valley Cottage, or Montebello, we also offer preventive roof treatment options to discourage regrowth.
