About This Service
Roof Moss Removal Done Right the First Time
Black streaking discolors a roof. Moss and lichen damage it. Where algae sits on the surface, moss builds a sponge that holds water against the shingle, works under the courses, and lifts edges — and in Capital Region freeze-thaw winters that trapped water expands and pries the shingle apart. Lichen is worse: it roots into the shingle mat itself. Both need to be killed chemically and allowed to release on their own, never scraped or blasted.
Why It Matters
What You Get With Capital Pro
Stops Freeze-Thaw Damage
Removing the moss mat removes the water it holds against your shingles, which is what does the real damage over an Upstate winter.
No Scraping, No Pressure
Scraping moss tears granules and lifts shingle edges. We kill it and let it release naturally with weather over the following weeks.
Kills Lichen at the Root
Lichen anchors into the shingle mat, so surface removal never works. Our solution kills the organism so it dies back and washes away.
Treats the Algae Too
Moss almost always arrives after Gloeocapsa magma. We treat the whole roof so you're not back with black streaks next season.
Warranty-Safe
ARMA-approved low-pressure method that keeps your shingle manufacturer's warranty intact.
Prevention Advice Included
Zinc or copper strip placement, trimming overhanging limbs, gutter flow — we tell you what will actually keep it from coming back.
Why It Matters
Moss Is a Structural Problem, Not a Cosmetic One
A moss mat behaves like a sponge bolted to your roof. It holds rainwater against the shingle surface long after the roof would otherwise have dried, softens the asphalt mat underneath, and grows under the shingle edge until it lifts it. Once an edge is lifted, wind gets under it and water gets behind it.
In the Capital Region the freeze-thaw cycle turns that into real damage. Water held in the moss freezes, expands, and works the shingle apart from underneath, then thaws and does it again — dozens of times between November and April. Homeowners who put off moss removal for a few seasons often end up replacing slopes rather than cleaning them.
The Right Method
Why We Never Scrape or Pressure Wash Moss
Scraping and pressure washing both feel productive because the moss comes off immediately. Both also take the shingle's granule layer with it and lift edges that were previously sealed, which is precisely the damage you were trying to prevent.
The correct approach is chemical: kill the organism, then let the dead material dry, shrink, and release with wind and rain over the following weeks. The roof continues to improve for a month after we leave. It takes patience, and it's the only method that doesn't cost you shingle life.
Prevention
Keeping Moss From Coming Back
Moss needs shade and moisture. The single most effective prevention is light: trimming back limbs that overhang the roof lets slopes dry after rain, and it also cuts the debris load that gives moss something to root into.
Zinc or copper strips installed near the ridge release trace metal ions in rainwater that suppress regrowth on the slope below. Keeping gutters flowing matters too — a backed-up gutter keeps the bottom course of shingles damp all season. We'll tell you which of these is worth doing on your specific roof rather than selling you all three.
Our Process
Simple, Professional, Guaranteed
Roof Assessment
We identify what you actually have — surface algae, established moss mats, or rooted lichen — since each responds differently and takes different dwell time.
Firm Written Quote
Measured remotely from satellite imagery in most cases, priced flat and in writing. Free on-site quotes whenever you'd rather we walk it.
Protect the Property
Landscaping, lawn, and plantings soaked with fresh water and covered before any solution is applied.
Treat & Dwell
A professionally diluted ARMA-approved solution is applied at rinse pressure and given the dwell time moss and lichen need to be killed through, not just wetted.
Gentle Rinse, No Scraping
A low-pressure rinse takes the loose material off. Anything still attached is dead and releases with the next few weeks of weather — pulling it off by hand would take granules with it.
Gutters & Prevention
Gutters and downspouts flushed of moss debris, then a walkthrough covering what's driving the growth and how to slow its return.
