Is Your Roof Covered in Black Streaks, Algae, or Moss? We Fix That Every Day Across Long Island

If you're seeing dark stains running down your shingles, green patches building up on the edges, or thick moss spreading across the ridge that's not just ugly, that's damage happening in slow motion. Those black streaks are a bacteria called Gloeocapsa Magma. That green stuff is algae and moss eating into your shingles. Left alone, it shortens your roof's lifespan by years. We've cleaned hundreds of roofs across Long Island, and we know exactly what it takes to get a roof looking brand new again safely, without cracking a single shingle.

Black Streak & Algae Removal from Long Island Roofs

Those black streaks on your roof aren't dirt they're a living bacteria feeding on your shingles. Our roof cleaning process targets and eliminates Gloeocapsa Magma completely, restoring your roof's original color without any scrubbing that could damage your shingles or void your warranty.

Moss & Lichen Treatment for Long Island Homes

Moss is one of the worst things that can grow on a roof because it holds moisture directly against your shingles 24/7. We apply the right treatment that kills moss at the root, removes it cleanly, and leaves a protective result so it doesn't come back fast. Homeowners in Rockville Centre and Huntington call us every spring specifically for this.

Safe Soft Washing for Asphalt Shingles & Tile Roofs

We don't just blast your roof with high pressure and hope for the best. For most residential roofs, we use a roof soft washing method low pressure combined with professional-grade cleaning solution that removes everything without lifting shingles or causing granule loss. It's the right way to clean a roof, and it's what we do on every job.

What Long Island Homeowners Say After We Clean Their Roof

One customer in Massapequa said her roof looked like it did when the house was built 15 years ago. Another in Smithtown told us he was two weeks away from paying for a full roof replacement before we cleaned it and showed him it had years of life left.
