Built on trust, and having your best interest.
JNR Industries is a roof maintenance company — Portland-based, owner-run, and over 25 years into doing the job honestly and with integrity.
Three things that set us apart.
A Treatment That is Safe for Your Home
Made in the USA — no zinc, no bleach, no peroxide. Effective on the moss, easy on your roof. A safer alternative that works much better than mainstream sulfates typically used by other companies.
You See What We See
Every job includes a full roof inspection with photos emailed to you.
Owner-Run and Genuinely Rated
Jesse and the crew have earned a 5.0★ rating across 60+ reviews on Google and Yelp — Jesse answers every one personally.
In the Pacific Northwest, moss is not a maybe.
Your home is your most valuable possession — Left alone, moss lifts shingles, traps moisture, and shortens the life of your roof. JNR removes it and treats the surface so it stays clean far longer, without the harsh chemicals.
A safe, USA-made treatment — not a shortcut chemical.
Every roof gets the same eco-friendly, USA-made formula, whether it's a small bungalow or a multi-building complex. Here is exactly what is in it, and what we keep out.
The Formula
- USA-made
- Eco-friendly
- Active ingredient: potassium salts of fatty acids — essentially a plant-based soap
- Biodegradable surfactants so it grips the roof instead of rinsing off in the first hard rain
- The active ingredient is actually a food additive so you know that it is safe
- Works best with annual maintenance
What We Never Use
- Zinc or zinc sulfate
- Bleach
- Peroxide

We would guide you in the right direction.
Will tell you when cleaning is not the answer.
There is no incentive to steer a homeowner toward a bigger job than they need. If a roof is too far gone for cleaning to buy it meaningful years, we will say so and point toward our roofing trade partner.
Great work is not cheap, and cheap work is not great — see exactly how that plays out in our estimate process.
5.0 stars, 60+ reviews — and we read every one.
