Roof Care Built Around Your Roof
From eco-friendly moss treatment to driveway sealing, JNR Industries handles the exterior maintenance that keeps a Portland-area home protected through the wet season.
Eco-Friendly Moss Treatment
A gentle, US-made treatment — no zinc, no bleach, no peroxide — that keeps moss from coming back without stressing your shingles. Treatment is the standard; hand-brushing is only used when a roof calls for it.
Roof Cleaning
Composition roofs are our primary focus, with metal roof cleaning done in dry, hot summer conditions, plus tile and cedar roof service. We also treat roofs with solar panels.
Driveway Sealing
Protect your driveway from Portland's wet winters with professional sealing that extends its life and curb appeal.
Leaf-Drop & Gutter Guard
Gutter cleaning and gutter guard installation to keep leaf-drop season from backing up your roof edges and downspouts.
Moss Doesn't Stay Small
Left alone, moss holds moisture against your shingles, lifts them at the edges, and spreads across the whole roof plane — season after season. JNR's treatment goes on gentle, and it keeps working even if the weather turns and it starts raining right after we leave.
- No zinc, no bleach, no peroxide — a US-made treatment that's easy on your roof
- Works even when it's wet outside
- Hand-brushing used only where a roof needs it, not as the default method
A Clean, Protected Roof
After treatment, your roof looks like new and stays protected from the moss growth that shortens shingle life. We always start with a free, in-person roof check — Jesse looks the roof over himself and reports back to you with photos, so you know exactly what you're working with before anything is scheduled.
