How much does gutter replacement cost in Portland?

Replacing gutters in Portland with All Season Continuous Gutters & Roof Care costs $8 to $12 per foot for a complete seamless aluminum system with outlets, corners and downspouts. A single‑story home with about 150 feet of 5‑inch gutter typically comes to $1,200–$1,500. Rotted fascia, unusual profiles and tall or steep rooflines raise the price.

Published Portland guides quote anywhere from $4 to $30 a foot because they average many companies and many homes. Ours is one crew’s actual rate card, and the gutter cost calculator applies it to your roofline in about two minutes.

Repair or replace? Six honest tests.

If your gutters fail one or two tests, a repair visit from $295 usually makes more sense. Fail three or more, and you are paying to patch a system that is wearing out everywhere at once.

Gutter repair versus replacement checklist for Portland homes
Test Repair it if Replace it if
Age & material Aluminum under about 20 years that still holds its shape. Galvanized steel near 20 years, aluminum past 20–30 with failing joints, or vinyl that has cracked.
Leaks One or two corners or end caps drip. Sectional gutters leaking at seam after seam along the run.
Sagging A few hangers pulled loose from solid wood. Sags come back because the fascia behind them is soft or rotted.
Rust & holes A pinhole or a single rusted spot. Rust through the bottom of a steel channel in more than one place.
Overflow Water spills only when the gutters are full of needles and leaves. Clean gutters still overflow in a steady rain because 5‑inch is too small for that roof plane.
Pitch One short run holds a little water. Long runs hold standing water because they were hung flat or backward.
Stained, worn gutter with streaks down its face and a bent hanger along a roof edge
Black streaks down the face mean water has been spilling over the front edge for years.

What worn‑out gutters look like on Portland homes

The first sign is rarely a broken gutter. It is what the water leaves behind on the house and in the yard.

  • Tiger stripesDark streaks on the gutter face where water overflows the front lip.
  • Dark fasciaA wet line or peeling paint on the board behind the gutter.
  • Open mitersCorners and end caps separating, dripping at every joint in the rain.
  • Standing waterPuddles left in the channel days after a storm.
  • Washed‑out bedsBare soil and splashed siding where water falls instead of draining.

How long gutters last, by material.

Should you replace 20‑year‑old gutters? Often, yes. The International Association of Certified Home Inspectors rates galvanized steel gutters at about 20 years and aluminum at 20 to 40+. Sectional systems usually fail at the seams first, because every joint is a place for sealant to dry out. Seamless runs only have joints at corners and outlets.

What happens on replacement day

How long it takes depends on the size and height of the home, how complex the roofline is, how many downspouts it needs and how much fascia needs work. Your written estimate tells you what to expect before we start.

  1. 1 Measure & lay out Every run, corner, valley and downspout route measured and explained on your estimate.
  2. 2 Take down the old system Old gutters and downspouts come off and the fascia gets checked for soft spots.
  3. 3 Fix the wood Rotted fascia replaced so new hangers bite into solid wood.
  4. 4 Roll‑form on site Each run formed from coated aluminum coil at your house, one piece per run.
  5. 5 Hang & pitch Hangers into solid wood, each run pitched toward its outlets so water doesn’t sit.
  6. 6 Downspouts & discharge Water routed at least 6 ft from a basement or 2 ft from a crawlspace, per the City of Portland.
  7. 7 Walk‑through Outlets flow‑checked, scraps hauled off, and the finished system walked with you.

5‑inch or 6‑inch for Portland rain?

Replacement is the cheapest moment to fix an undersized system. Most Portland homes do fine with 5‑inch K‑style. Large roof planes, valleys that pour into one short run, and steep pitches often need 6‑inch gutters with 3×4 downspouts, which also clog less under firs and maples.

Oregon is one of the states still sized with NOAA Atlas 2 design‑storm data. NOAA’s new Atlas 15 is replacing it, so we size from roof area and local rainfall rather than a rule of thumb.

Ask us a question

How much does gutter replacement cost in Portland?

We charge $8 to $12 per foot for a complete seamless aluminum system with outlets, corners and downspouts: $8–$10 for 5‑inch K‑style and $10–$12 for 6‑inch or our 6‑inch fascia profile. A single‑story home with about 150 feet of 5‑inch gutter typically costs $1,200–$1,500.

Should I replace 20‑year‑old gutters?

Often, yes. Galvanized steel gutters last about 20 years and aluminum 20 to 40+, according to InterNACHI. If 20‑year‑old gutters leak at several seams, sag over soft fascia or overflow when clean, replacement usually costs less than repeated repairs.

Is it better to repair or replace gutters?

Repair when the problem is local: one leaking corner, a few loose hangers, a crushed downspout. Replace when the same failures show up along the whole system, the fascia behind it is rotting, or clean gutters still overflow because they are too small.

Do gutters need to be removed when replacing a roof?

Not always. Sound gutters can often stay or be detached and reset. If your gutters are near the end of their life, replacing them right after the new roof avoids paying to reset an old system.

Should I get 5‑inch or 6‑inch gutters?

Most Portland homes do well with 5‑inch K‑style. Large roof planes, valleys that dump into one run and steep pitches often need 6‑inch gutters with 3×4 downspouts. The gutter sizing calculator on our site works it out from your roof area.

How long does gutter replacement take?

It depends on the size and height of the home, the number of corners and downspouts, and how much fascia needs replacing. Your written estimate tells you what to expect before work starts.

Do I need a permit to replace gutters in Portland?

New gutters and downspouts on a one‑ or two‑family home generally don’t need a building permit in Portland. Work on drywells or underground drain pipe can need a plumbing permit.

Can my new downspouts go back into the sewer pipe?

If your home is in a City of Portland mandatory disconnection area and your downspouts were disconnected, reconnecting them to the combined sewer is prohibited without City approval under City Code 17.37. We plan discharge to stay within those rules.

What happens to rotted fascia during replacement?

We check the fascia once the old gutters are off. Soft or rotted boards are replaced before the new runs go up, which typically adds $250–$850 depending on how much wood is affected.

Is there a warranty on replacement gutters?

Yes. Every installation we do carries a lifetime warranty on our workmanship.

Should I add gutter guards when I replace my gutters?

If firs or maples hang over the roof, replacement is the easiest time to add them. Our gutter guards run $8.25–$15.95 per foot depending on the system, and they cut down on cleanings without making gutters maintenance‑free.
