Moss Removal
Killed At The Root
Moss isn’t cosmetic — it roots into granules, holds water against shingles through every freeze, and pries tabs as it thickens. Scraping spreads it; treatment kills it.
A Wet Sponge Stapled To Your Shingles
Moss holds moisture against the shingle surface around the clock — through every freeze-thaw cycle, prying granules loose and lifting tab edges as the mat thickens. North-facing and tree-shaded slopes go first. Scraping and pressure washing strip granules and scatter spores; our soft-wash treatment kills the growth at the root so it browns, dies, and releases with the weather, leaving the shingle surface intact.
After The Kill, Prevention
Moss returns where conditions invite it: shade, debris, and slow-drying surfaces. Trimming overhanging limbs, keeping gutters and valleys clear of debris that seeds growth, and zinc strips at ridges all extend the clean years. We’ll tell you which apply to your roof — part of the treatment visit, not an upsell call later.
What Homeowners Ask Us About Roofs
How long until the moss is gone after treatment?
It dies immediately and browns within days; thick mats release over the following weeks as weather works them loose. We never rip live mats off — that is how shingles get torn.
Will moss removal damage my plants below?
We pre-wet and rinse landscaping and control runoff as part of the process.
My roof is heavily mossed and old — is treatment still worth it?
Sometimes the honest answer is that moss is holding a failing roof together — we will tell you if treatment or a replacement conversation is the better spend.
Is moss on a roof really a problem?
Yes — it holds water against shingles through every freeze-thaw cycle and pries tabs as it thickens. It’s a slow-motion roof problem, not a cosmetic one.
Does zinc really keep moss off a roof?
Zinc and copper strips at the ridge wash trace metal down the slope and meaningfully suppress regrowth — a helpful layer after treatment, not a substitute for it.
Can I pressure wash moss off my roof?
Please don’t — pressure strips granules, drives water under tabs, and scatters live spores. Treatment kills moss; pressure just redecorates with it.
What kills moss on roofs naturally?
Sunlight and dryness — which is why trimming shade branches matters. For active mats, treatment chemistry is the reliable kill; zinc strips slow the return.
Does moss grow back after treatment?
Where shade and moisture persist, eventually — treatment plus condition changes (limbs, debris, zinc) stretches the clean years dramatically.
