Moss Treatment
Moss treatment services are used after moss removal to help prevent regrowth on roofing and exterior surfaces. Even after visible moss is removed, spores can remain and begin growing again in shaded or moisture-prone areas.

How long does the treatment last?
Roughly 12 months in PNW conditions. We'll recommend a re-application schedule based on your roof type and tree cover.
How do you protect plants during treatment?
We apply carefully and keep the treatment off sensitive surroundings, rinsing as needed. Let us know about anything delicate and we'll plan the application around it.
