Portland’s rainy season starts with a dry week. Fix leaking and sagging gutters before December.

Portland, Ore. — Nov. 1, 2026. The Northwest rainy season begins today, and KGW meteorologist Rod Hill expects it to be shaped by a very strong, so-called “super” El Niño. His outlook favors “a somewhat dry November, followed by a very wet December and January.” The last super El Niño, in 2015–16, gave Portland nearly a foot of extra rain from November through March.

The near-term forecast lines up with that. KOIN 6 expects the region to stay dry through midweek under a ridge of high pressure, with showers returning Wednesday evening and a few more on Friday. For a homeowner with a gutter that drips at the corners or sags in the middle of a run, those dry days are the cheapest time all winter to get it fixed. Update, Nov. 2: NOAA now flags an atmospheric river for the Northwest on Nov. 10–12. Here’s the gutter-cleaning window before it.

The forecast

What this winter’s outlook means for a gutter that already leaks

Hill’s outlook says atmospheric rivers will most likely aim at California in December, but one or two could shift north into Oregon and deliver 8 to 12 inches of rain in the month, raising the flood risk. He also notes that strong south winds in the valley tend to be more common in El Niño winters.

For gutters, that’s two kinds of stress at once. Long, steady rain finds every open seam and every low spot in a run. Wind finds every loose hanger. A gutter that holds water, wet needles and moss is heavier than it was built to carry, and a gusty south wind on a run that’s already pulling away from the fascia is how sections end up on the lawn.

Five gutter problems to fix before the wet months, and what each one costs

These are the repairs we see most on Portland homes after the first fall storms. The ranges come from our current repair pricing and are estimates, not final quotes.

1. $75–$200

   Drips at corners and seams

   Old sealant fails at a miter or a sectional seam opens up. Clean, re-seal or re-miter the joint.

2. $125–$350

   A run sags or pulls away

   Hangers spaced too far apart, loose in the wood or bent by water weight. Re-hang and reset the pitch.

3. $50–$150

   Water pours over the front

   Packed debris, a low spot in the pitch, or too few outlets. Clear, re-pitch, or add an outlet.

4. $95–$275

   Downspout loose or backing up

   Separated elbows, a clogged outlet or a crushed section near the ground. Reconnect, clear or replace.

5. $250–$850

   Dark stains or soft fascia

   Years of overflow rot the board behind the gutter. Replace the rotted section, then re-hang.

On most homes the first sign isn’t a broken gutter. It’s a dark streak on the fascia, a drip line in the bark dust, or mulch washed away below a corner. Check from the ground on the next rainy evening with a flashlight. Drips at the corners mean seams. A sheet of water over the front edge means a clog or a pitch problem. A run that looks wavy from the street usually means hangers.

The angle most coverage missed

Wind is the repair deadline nobody mentions

Winter outlooks focus on rain and snow totals. The line that matters most for gutters is near the end of KGW’s outlook: strong south winds are more common in El Niño winters, and Hill expects three or four wind warnings in the valley.

A sealed seam can wait for a dry afternoon in January. A loose hanger can’t, because the first windstorm doesn’t care whether the run is full. If a section already moves when you tug it from a ladder, or you can see daylight between the gutter and the fascia, have it re-hung before December. Re-hanging a run costs far less than replacing a section that tore off and bent the downspout on the way down.

• Look for gaps between the back of the gutter and the fascia board.

• Check for hangers that have backed out of the wood or bent downward.

• Watch for runs that dip in the middle and hold water after rain stops.

• Make sure downspout straps are tight. A loose downspout acts like a lever on the outlet.

Hiring it out

How to vet a gutter repair contractor in Oregon after the Oct. 20 lawsuit

On Oct. 20, Oregon Attorney General Dan Rayfield sued SFW Construction, a regional residential contractor, in federal court in Portland. According to the Department of Justice, the complaint says the company used a standard contract since 2022 that restricted customers’ right to post negative reviews, without telling potential customers, while its website showcased glowing reviews. The lawsuit alleges violations of the federal Consumer Review Fairness Act and Oregon’s Unlawful Trade Practices Act. These are allegations in a lawsuit, not findings by a court.

“Before you let someone work on your home, you read the reviews,” Rayfield said in the release. “But reviews only mean something if customers are free to tell the truth, good or bad.” For anyone hiring a gutter repair this month, that translates into a short checklist.

• Check the contractor’s license with the Oregon Construction Contractors Board. Ours is CCB #233705.

• Get it in writing. The CCB says construction agreements over $2,000 must be written, and recommends writing down every change too.

• Read the contract for anything that limits what you can say about the work afterward. That kind of clause is what the state is challenging.

• Ask for an itemized repair estimate that names each problem and what fixing it costs, not one lump sum for “gutter work.”

• Ask for photos of what was found and what was fixed, especially for work you can’t see from the ground.

The DOJ says Oregonians who think a business used a form contract to block an honest review can file a complaint at oregonconsumer.gov or by calling 1-877-877-9392.

Cost

What gutter repair in Portland costs this fall

Our gutter repair in Portland starts at $295, our service-call minimum. A typical repair visit runs $295–$650 on a single-story home and $345–$950 on a two-story home. Specific problems add to that: about $75–$200 to re-seal leaking corners, $125–$350 to re-hang a sagging run, and $250–$850 when fascia has rotted. A proper repair starts with checking slope, hanger spacing, seams, outlets and downspout flow. Sealing a leak doesn’t help much if the gutter is holding standing water.

When a system has failing seams in several places, rusted sections or rotted fascia along most of a wall, repairs stop holding and gutter replacement is the better spend. If the trouble is at ground level, start with downspout repair and cleaning. And if a gutter overflows only because it’s full, a gutter cleaning may be all it needs.
