Roof Cleaning Long Island, NY
Trusted Soft Wash Roof Cleaning Across Nassau & Suffolk County
If your Long Island roof is covered in black streaks, green moss, or spreading algae, Benny's Home Services is the local expert you need. We're a fully insured soft wash roof cleaning company serving Nassau and Suffolk County, using a low-pressure, biodegradable system that kills algae, moss, mildew, and lichen at the root — not just on the surface. We offer free on-site and remote satellite estimates, so getting a quote is fast, easy, and commitment-free.
Long Island's humid coastal environment — with moisture flowing off the Atlantic Ocean, Great South Bay, Long Island Sound, and the Island's many inlets and harbors — creates ideal conditions for biological growth on roof surfaces year-round. The black streaks you see are caused by Gloeocapsa Magma, a hardy algae that feeds on the limestone in asphalt shingles. Moss takes root in shaded, damp sections, traps moisture against your shingles, and slowly destroys your roof from the outside in. Left untreated, both spread year after year, shortening your roof's lifespan and hurting your home's curb appeal and value.
Our soft wash roof cleaning process is the method recommended by the ARMA (Asphalt Roofing Manufacturers Association) and by major shingle brands including GAF and CertainTeed. Unlike high-pressure washing — which strips protective granules from your shingles and can void your warranty — soft washing uses low pressure and a professional-grade cleaning solution to safely dissolve and kill organic growth at its source. The result lasts far longer than pressure washing and won't damage your roof in the process. We treat asphalt shingles, cedar shake, tile, slate, and metal roofs throughout Long Island.
Insurance is one of the top reasons Long Island homeowners call us. Carriers across Nassau and Suffolk County use aerial and satellite inspections to flag roofs with visible algae, moss, or staining — and many issue non-renewal notices to homeowners who fail to address it. A professional soft wash cleaning with before-and-after documentation is typically all that's needed to satisfy your insurer. If you've received a letter from your insurance company about your roof, contact us right away and we'll prioritize your job.
We serve every community on Long Island — from the Five Towns and the South Shore to the Gold Coast, the North Shore, the Hamptons, and the East End. Our crews are locally based, scheduling is fast, and there are no travel surcharges. Contact us today for a free estimate or browse our town pages below.
