Why Rockland County roofs get black streaks and moss
Rockland County sits in the humid Lower Hudson Valley, where wooded neighborhoods, the moisture off the Hudson, lingering morning dew, and hard freeze-thaw winters keep roofs damp for long stretches. That is exactly what black algae, moss, and lichen need to take hold, which is why so many roofs in the county develop dark streaks, especially on shaded, north-facing slopes.
Left alone, that growth does not just look bad. Algae, moss, and lichen trap moisture against the shingles and shorten your roof’s life. The good news: it is almost always fixable with a proper cleaning, no replacement required.
Our safe soft washing method
Soft washing is the method roofing manufacturers actually recommend. We apply a biodegradable cleaning solution at low pressure that kills algae, moss, and lichen at the root, let it work, and gently rinse. Because we are a licensed roofing contractor — not just a cleaning crew — we also keep an eye out for loose flashing, worn areas, or early leaks while we are up there.

How much does roof cleaning cost in Rockland County?

What causes the black streaks on Rockland County roofs?
They are caused by a blue-green algae called Gloeocapsa magma, which feeds on the limestone in asphalt shingles and spreads by airborne spores. Rockland County’s humidity and tree cover make roofs especially prone to it, usually on shaded, north-facing slopes.
Do you soft wash or pressure wash roofs?
We soft wash. Soft washing uses low pressure and a biodegradable solution to remove algae, moss, and lichen without stripping shingle granules or voiding your warranty. We never high-pressure wash an asphalt roof.
Which Rockland County towns do you serve?
We serve Rockland County throughout, including Nanuet, New City, Nyack, Suffern, Pearl River, Spring Valley, Pomona, and Valley Cottage, and surrounding communities. Call (877) 492-9014 to confirm we cover your street.
How long will my roof stay clean after a soft wash?
Typically several years, because soft washing kills the algae and moss at the root rather than just rinsing the surface. Cheaper pressure washing tends to let the streaks return within months.
