Gutter Cleaning + Roof Moss Removal in Portland, OR

Portland gutter cleaning and roof moss removal calls typically invoice $150 to $1,500, with steep two-story Pearl District lofts, NE oak-and-maple-canopied bungalows, and zinc-strip moss treatments on long north-facing slopes pushing toward the high end. ORGutterPro is an Oregon CCB-licensed gutter and moss-removal scheduling directory — call PHONE to be matched with a licensed crew serving the Pearl District, NE Alberta, SE Hawthorne, Multnomah Village, and the rest of Portland across ZIPs 97201, 97202, 97203, 97206, and 97214.

How the referral works in Portland

ORGutterPro does not perform gutter cleaning, roof moss removal, or any roof or exterior work directly. We do not employ technicians and we do not hold an Oregon CCB license. We operate a scheduled-service pay-per-call dispatch directory. When a Portland homeowner or property manager calls the number on this page, the call routes through our affiliate network to an independent Oregon CCB-licensed contractor serving Multnomah County. The crew arrives, walks the roof line and gutter run, and hands you a flat-rate written quote before the ladder leaves the truck. You pay the contractor directly. Our compensation comes from the network only when a job is booked. Oregon is a one-party consent state for call recording under ORS 165.540 — disclosure is provided at call connection.

What our Portland crews handle

Pre-rain-season fall clearance of Douglas fir needles, Western red cedar foliage, and big-leaf maple debris from the dense canopy across NE Alberta, Irvington, and Hawthorne neighborhoods
North-facing roof moss and lichen removal on composition shingle roofs throughout the West Hills, Multnomah Village, and Sellwood — the slopes that never see direct summer sun and stay damp ten months a year
Zinc-strip and zinc-sulfate moss-prevention treatment on long roof spans typical of mid-century ranches in the SE 82nd corridor
Steep-roof harness work for two-story foursquares and Victorians in Irvington, Laurelhurst, and the Alameda Ridge where ladder-only access is unsafe
Downspout flushing and underground drain-line clearing for older homes with terra-cotta roof drains tied directly to the city’s combined sewer
Gutter pitch correction and hanger replacement on early-1900s Pearl District and Hawthorne homes where the original spike-and-ferrule fasteners have pulled loose
Post-ice-storm debris cleanup — the February 2021 ice event tore Doug-fir limbs off the canopy across SE Portland, and many gutters were never fully cleared afterward
Gutter guard and leaf-screen installation tuned to fine Doug-fir needles, which slip past most big-mesh designs
Recurring twice-yearly maintenance plans for landlords managing the city’s 100,000+ aging single-family rental stock

Typical cost in Portland

A Portland gutter cleaning typically runs $150 to $400 for a single-story home with average debris and $250 to $600 for a two-story with conifer overhang. Roof moss treatment runs $300 to $1,200 depending on roof area and severity. Combined gutter clean + downspout flush + moss treatment for a two-story Hawthorne or Alberta bungalow runs $400 to $900. Steep-roof harness premium adds $100 to $300. Gutter guard install on a 150-foot run is $800 to $2,500 depending on product. Cost figures aggregated from HomeAdvisor and Angi for the Portland metro.

Insurance, foundation water, and Portland homeowners

Portland’s clay-heavy soils don’t drain well, and a clogged gutter that overflows for an entire winter season directs roof water straight to the foundation perimeter. The cost of a $250 fall cleaning is trivial compared to the $5,000–$30,000 cost of basement-wall waterproofing, sump-pump retrofit, or fascia and soffit replacement after a season of overflow. Most Oregon homeowners insurers explicitly exclude gradual water damage from clogged gutters as “homeowner maintenance failure” — meaning the insurer will not pay to repair rotted fascia, mildewed siding, or soaked structural framing if the underlying cause was a gutter the homeowner never cleaned. Schedule the fall cleaning before the rains start and document with dated photos.

How to choose a gutter contractor in Portland

Verify Oregon CCB license at oregon.gov/CCB before signing any contract over $1,000 (ORS 701)
Ask for a current certificate of insurance: $500,000 general liability minimum and active workers’ comp for any crew working on your roof
For steep-roof or two-story work, confirm the crew uses OSHA-compliant fall protection (harness + roof anchor) — not just an extension ladder
Get the quote in writing as flat-rate, not time-and-materials; Portland gutter calls should be priced per linear foot or per stories, not by the hour
For moss treatment, ask whether the product is zinc-sulfate, zinc-strip retrofit, or a proprietary blend — and whether the crew bags and removes the dead moss after treatment or leaves it to break down
Save the dated before-and-after photos for your insurance file in case a future claim involves a roof or fascia question

Frequently asked questions

When in the year should I schedule gutter cleaning in Portland?

Late October through mid-November is the sweet spot. By that point Douglas fir and Western red cedar have dropped most of their seasonal needles, big-leaf maples have shed their leaves, and the heavy rain hasn't yet started. Schedule before the first sustained rain front in November — once the gutters are full and saturated, the cleaning takes longer and costs more, and any overflow that's already happened may have already started water-damaging the fascia. If your home has heavy conifer overhang in NE or SE Portland, a second cleaning in late February or March catches the remaining drop.

Why is roof moss such a big deal on Portland roofs specifically?

Portland's combination of mild winters, 36+ inches of annual rain, and dense tree canopy creates the perfect environment for moss and lichen to take hold on north-facing composition shingle roofs. The moss isn't just cosmetic — it lifts the granular surface and the edge of each shingle, channels water under the shingle rather than over it, and shortens roof life from a 25-year warranty to closer to 15. Moss treatment with zinc-sulfate (or installation of zinc strips at the ridge) is significantly cheaper than premature roof replacement.

Did the February 2021 ice storm really make this worse for years afterward?

Yes — and many Portland homeowners are still finding out. The ice storm broke Doug-fir branches across SE and NE Portland; some landed in gutters and were never fully removed because they were embedded in ice. Once the ice melted and the debris settled, gutters across thousands of homes were carrying significantly more material than usual through the spring 2021 rain season. If your home has not had a full hand-clearing since before the ice storm, the gutter probably still contains compacted debris near the downspout outlet. A licensed crew can confirm in 5 minutes from the ladder.

Does Portland require a permit for gutter or moss work?

Standard gutter cleaning and moss treatment do not require a permit in Portland. Permits become relevant only if the work expands into structural fascia replacement, full-roof replacement, or new gutter system installation that ties into stormwater drainage. For most pre-rain-season cleanings and moss treatments, the contractor's CCB license, insurance, and OSHA fall-protection compliance are the relevant credentials — not a Portland Bureau of Development Services permit. Always ask before signing if the scope includes any structural roof or fascia work.

Can the crew clean gutters in the rain?

Most Portland CCB-licensed crews will work in light rain but stop in steady or heavy rain — both for crew safety on a wet roof and because cleaning a gutter while water is actively flowing through it doesn't accomplish much. The crew will reschedule rather than do half a job. Booking earlier in the fall (October–early November) gives the most weather flexibility before the steady November–March pattern locks in. Dry-day windows in mid-winter are real but unpredictable, so the lead-time can stretch.
