Roof Cleaning & Moss Removal Services
Professional roof cleaning for homes in Ithaca & the Finger Lakes. Our soft wash method safely removes moss, algae, and black streaks to extend your roof's life.
What's Growing on Your Roof?
Those dark stains and green patches aren't just ugly — they're damaging your roof
Black Streaks (Gloeocapsa Magma)
These dark streaks are caused by algae that feed on limestone in shingles. Left untreated, they spread and can shorten your roof's lifespan.
Moss & Lichen Growth
Moss retains moisture and can lift shingles, allowing water to seep underneath. This leads to rot, leaks, and expensive repairs.
Premature Aging
Algae and moss cause shingles to deteriorate faster, potentially voiding your warranty and requiring costly replacement sooner.
Safe Cleaning, Lasting Results
We use a low-pressure soft wash technique — NOT high-pressure washing that can damage shingles. Our specialized biodegradable solution kills the algae, moss, and bacteria at their roots.
This method is approved by shingle manufacturers like GAF, Owens Corning, and CertainTeed, ensuring your warranty remains intact while extending your roof's lifespan.
The results last 4-6 times longer than pressure washing because we eliminate the organisms causing the problem, not just the surface stains.

Your Questions Answered
Common questions about roof cleaning and soft washing in the Ithaca & Finger Lakes area
No — the opposite. High pressure is what voids shingle warranties, since it strips the protective granules off the surface. Our process follows the guidelines of ARMA (the Asphalt Roofing Manufacturers Association) for low-pressure cleaning — the method manufacturers like GAF, Owens Corning, and CertainTeed actually approve.
Yes. Soft washing removes moss, algae, and black streaks without stripping shingles. It treats growth at the source, so results actually keep improving for a few weeks as the organisms die off.
Results typically last 3–5 years, and we back that with a 3-year warranty. If you see new growth before the 3 years is up, we come back and retreat it at no charge.

“Six Mile cleaning did an amazing job on our house. The house had loads of algae on the siding and moss growing on the roof and they got it completely clear. They also did a gutter cleaning which was long overdue. Oliver and his crew arrived on time, did a beautiful job, and completely cleaned up all the mess. I couldn't be happier!! I even thought the price was reasonable.”
