Roof Cleaning in Gresham, Oregon — Moss Off the Metro's Fourth-Largest City
JNR Industries has listed Gresham on its published service area since at least August 2013 — soft-wash moss removal and an eco-friendly, US-made treatment for the tree-shaded comp roofs from Rockwood to Powell Valley.
A Gresham roof has Gresham problems.
Gresham is Oregon's fourth-largest city — 114,247 people at the last census, spread across sixteen recognized neighborhoods from Rockwood's MAX-line density in the west to the quieter, more rural Pleasant Valley and Powell Valley areas pushing up against Damascus in the east. The city grew out of berry, dairy, and nursery farmland, and that transition shows up directly in the roofs: established lots in Northwest Gresham and Rockwood carry 1980s-and-90s composition shingles under decades-old Douglas fir and bigleaf maple that never got cleared when the subdivisions went in.
That's the moss story in one sentence — mature tree canopy over mid-life comp roofs, in a city big enough that Precision Castparts, Legacy Mount Hood Medical Center, and Mt. Hood Community College all anchor real employment districts around it. JNR has listed Gresham on its published service area since at least August 2013, and the drive out from the Happy Valley shop is a short one — about eight miles, roughly 14 minutes up US-26.
Every service, dialed to Gresham homes.
Roof Cleaning & Eco-friendly Moss Treatment
Rockwood and Northwest Gresham's 1980s-90s comp roofs sit under decades-old Douglas fir and bigleaf maple that never got cleared for the subdivisions — that shade-and-needle combination is exactly what grows moss fastest, and JNR kills it at the root instead of scraping the surface.

Leaf and needle litter off the mature canopy in North Gresham and Hogan Cedars clogs gutters every fall; JNR clears them and checks downspout runs before the rainy season backs anything up.
Learn more »Pressure Washing
JNR soft-washes Rockwood's split-level ranch homes and the newer construction off Powell Boulevard alike — never a blast that strips granules or drives water behind the siding.

From 1980s tract homes in Northwest Gresham to older farmhouses near Historic Southeast, JNR patches flashing and worn shingles on the spot before a small leak becomes a ceiling stain.
Learn more »Roof Maintenance Plan
A standing maintenance visit keeps moss from re-establishing on Gresham's shaded comp roofs between the metro's wet winters.
Learn more »Tree Trimming
JNR trims back branches overhanging rooflines in leafy neighborhoods like Kelly Creek and Pleasant Valley so the shade that feeds moss doesn't come right back.

Close enough to show up.
JNR runs out of the Happy Valley shop on Portland's east side — Gresham is about eight miles and a fourteen-minute drive up US-26, closer to home than most of the other service-area cities on the list.
The treatment matters here.
A lot of Gresham's tract-home stock from the 1980s and 90s wasn't built with today's algae-resistant shingles, and bleach or zinc runoff leaves streaking and kills nearby landscaping fast on established lots. JNR's eco-friendly, US-made treatment — no zinc, no bleach, no peroxide — kills moss at the root without the runoff that damages lawns and garden beds in family neighborhoods like Powell Valley and Pleasant Valley.
Neighborhoods & areas served.
Asked by your neighbors.
Does JNR clean roofs in every Gresham neighborhood, or just certain areas?
JNR works across Gresham — from Rockwood's split-levels near the MAX line to the newer construction off Powell Boulevard and the shaded lots around Kelly Creek and Pleasant Valley.
Why does moss come back so fast on Gresham roofs?
A lot of Gresham's housing sits under mature Douglas fir and bigleaf maple that predates the subdivisions. That shade keeps roofs damp long after a rain, which is exactly what moss needs to spread.
Is JNR's treatment safe for Gresham's older homes and gardens?
Yes — JNR uses an eco-friendly, US-made treatment with no bleach and no zinc, so there's no runoff streaking or garden damage on the established lots common in Northwest Gresham and Rockwood.
How far is Gresham from JNR's base?
JNR is based near Happy Valley, about eight miles and a fourteen-minute drive up US-26 to central Gresham.
Does JNR handle gutters as well as roofs in Gresham?
Yes — gutter cleaning and minor repair are part of the same visit, which matters in neighborhoods with heavy leaf and needle litter like North Gresham and Hogan Cedars.
Is JNR licensed to work in Gresham?
Yes — JNR carries Oregon CCB #214684 and Oregon DOA Commercial Chemical Operator license #AG-L1056261-CPO, both valid statewide. Call (503) 432-9093 for an estimate.
