10 Best Gutter Installation Companies in Portland, OR

TL;DR: The best gutter installation companies in Portland, OR for 2026 are American Gutter Service, Great Northwest Gutters, Royal Gutters, All Season Continuous Gutters, Stumptown Gutters, Blue Moon Roofing & Gutters, JT West Coast Gutter & Roofing, Interstate Roofing, Precision Roofing & Gutters, and Snugs Services. Each one publishes an Oregon CCB license number and installs seamless gutters in the Portland metro area.

Portland averages 36.92 inches of rain a year at the airport, according to the National Weather Service 1991 to 2020 climate normals, and most of it falls between October and May. Add Douglas firs, roof moss, and a lot of 100-year-old bungalows, and Portland gutters work harder than most.

That is why picking an installer matters. A good one sizes the gutters to your roof, places downspouts where the water can actually go, and stands behind the work in writing. A rushed one hangs whatever fits the truck.

This guide compares 10 Portland gutter companies side by side. You will see what each one is best for, its license number, where it works, published prices where they exist, and the Portland rules that affect your downspouts.

How We Picked the Best Gutter Installation Companies in Portland

We only included companies a homeowner can check without taking our word for it. Every company below shows an Oregon Construction Contractors Board (CCB) license number on its website, installs seamless gutters, and works in the Portland metro area.

We reviewed each company’s own website on September 25, 2026, and weighed six things:

1.  Licensing: A public Oregon CCB number you can look up.

2.  Seamless installation: Gutters formed in continuous runs, not short sections joined along the run.

3.  Gutter focus: Whether gutters are the main business or one service among many.

4.  Warranty clarity: Warranty terms stated on the website or offered in writing.

5.  Transparency: Published prices, founding dates, and who does the work.

6.  Portland fit: Coverage of specific parts of the metro, so every area has options.

Gutter Specialist or Roofing Company?

Portland homeowners usually choose between two kinds of installers. Neither is always better. It depends on whether your roof also needs work.

If your roof has more than a few years of life left, a gutter specialist is usually the simpler call. If a new roof is coming within a year, coordinate the two so the drip edge and gutters are installed in the right order.

What Does Gutter Installation Cost in Portland?

Seamless aluminum gutters in Portland usually cost about $7.75 to $13 per linear foot installed, based on the published prices on this list. Downspouts, old gutter removal, fascia repair, and gutter guards are usually priced separately, so compare itemized quotes, not totals.

Two companies on this list publish prices. American Gutter Service lists its rates line by line, and Blue Moon publishes a range of $10 to $13 per foot for 6-inch aluminum K-style gutters.

Worked example: A single-story Portland bungalow with 140 feet of gutter and five 15-foot downspouts would cost about $1,712.50 at AGS rates with 5-inch gutters and 2×3 downspouts (140 x $7.75, plus 75 x $6.50, plus 140 x $1.00 removal). Moving up to 6-inch gutters and 3×4 downspouts brings it to about $1,890. Fascia repair or guards would be added on top.

For a closer look at what drives the number, read our guide to how much new gutters cost in Portland.

Portland Rules Every Gutter Installer Should Know

A good Portland installer plans where the water goes after it leaves the downspout, not just where the gutter hangs. Two city rules shape that.

Permits. The City of Portland lists installing gutters and downspouts among home projects that do not need a building permit. A plumbing permit may still be needed for stormwater disposal, such as a new drywell or soakage trench.

Downspout disconnection. Many older Portland homes have downspouts piped into the sewer. The city’s downspout disconnection guidance says a permit is not required to disconnect using an extension and splash block. Water must be released:

• At least 6 feet from a basement, or 2 feet from a crawl space or slab foundation.
• At least 5 feet from a neighbor’s property line and 3 feet from a public sidewalk.
• Not on slopes greater than 10 percent, and not within 10 feet of a retaining wall.

If an installer proposes rerouting downspouts on a Portland home, ask how the plan meets these setbacks. Our downspout installation page covers sizing and placement.

What Portland Weather Means for Your Gutters

Portland rain rarely comes as one big storm. It comes as months of steady rain with needles, cones, and moss washing off the roof. That changes what a good gutter system needs.

• Fir needles and moss: Needles mat together in gutter corners and downspout openings. Homes under Douglas firs benefit most from micro-mesh gutter guards and larger 3×4 downspouts.
• Long wet season: Gutters carry water for much of the year, so seams and joints get more wear. Seamless runs remove joints along straight sections. Here is what seamless gutters are and why they matter.
• Older homes: Many Portland bungalows and Craftsman homes have original fascia boards. Ask each installer how they handle soft or rotten wood they find during tear-off.
• East winds and ice: East Portland, Gresham, and Troutdale get stronger winds and occasional ice from the Columbia River Gorge. Hanger spacing and secure downspout straps matter more there.

Our guide to common gutter problems in Oregon covers the warning signs to watch for between installs.

How to Vet a Portland Gutter Installer in Five Minutes

Before you hire any company on this list, or one that is not on it, run through these steps:

1.  Check the license. Enter the company name or CCB number in the Oregon CCB license search and confirm it is active with a bond and insurance on file.

2.  Ask if gutters are formed on site. Seamless gutters are cut to your measured runs, so there are no joints along straight sections.

3.  Get an itemized written estimate. It should list gutter size, footage, downspout size and count, removal, and fascia pricing. The Oregon CCB’s consumer tools recommend a written contract and warn against paying in full up front.

4.  Ask where the water will go. A good answer covers downspout placement, extensions, and Portland’s disconnection setbacks.

5.  Get the warranty in writing. Know which part covers materials and which covers labor.

6.  Ask who does the work. Employees or subcontractors, and who you call if a seam leaks next winter.

Best Gutter Installation Companies in Portland: FAQs

Who is the best gutter installation company in Portland, OR?

The best gutter installation company in Portland depends on your home and neighborhood. American Gutter Service is a gutter-only option with published prices. Royal Gutters suits copper and half-round projects. Interstate Roofing suits combined roof and gutter jobs. Always confirm an active Oregon CCB license first.

How much do new gutters cost in Portland?

New seamless aluminum gutters in Portland typically cost about $7.75 to $13 per linear foot installed. As published reference points, American Gutter Service charges $7.75 per foot for 5-inch white gutters, and Blue Moon lists $10 to $13 per foot for 6-inch aluminum. Downspouts and removal are extra.

Do you need a permit to replace gutters in Portland?

No building permit is needed to install gutters and downspouts on a home in the City of Portland. A plumbing permit may still be required for stormwater disposal, such as installing a drywell or soakage trench. Disconnecting a downspout with an extension and splash block does not need a permit.

What size gutters do Portland homes need?

Most Portland homes use 5-inch K-style gutters. Large roof areas, steep pitches, valleys that concentrate water, and homes under fir trees often need 6-inch gutters with 3×4 downspouts. A good installer sizes gutters from your roof and trees, not from what was there before.

Can I disconnect my downspouts in Portland?

Most Portland property owners can disconnect downspouts themselves. The city requires the water to discharge at least 6 feet from a basement or 2 feet from a crawl space or slab, 5 feet from a property line, and not on slopes steeper than 10 percent.

How long does gutter installation take in Portland?

Many standard Portland homes are finished in one working day when gutters are formed on site. Two-story access, steep roofs, fascia repair, and gutter guards can add time. Fall is the busiest season, so booking in late summer usually shortens the wait.

How do I check if a Portland gutter company is licensed?

Use the Oregon Construction Contractors Board license search at search.ccb.state.or.us. Enter the company name or CCB number to confirm the license is active and see its bond, insurance, and any complaint history. For Vancouver jobs, check Washington’s Labor and Industries contractor lookup too.

Choosing From the Best Gutter Installation Companies in Portland

The best gutter installation companies in Portland share the same basics: a license you can check, seamless gutters sized to the roof, downspouts placed with the city’s rules in mind, and a warranty in writing. Start with the companies that serve your part of town, get two or three itemized quotes, and compare them line by line.

If you live in Portland, the westside, the east metro, or Columbia County, we would be glad to give you one of those quotes. American Gutter Service has installed and repaired gutters for more than 20 years and publishes its prices so you can compare with confidence.
