In much of the country, gutter cleaning is a once-a-year chore. In Western Washington, one cleaning does not get the job done. Douglas fir and hemlock drop needles from late summer through the first big windstorms, bigleaf maples dump leaves the size of dinner plates in late October and November, and alder and cottonwood fill in the gaps between. A gutter cleaned in September on a Snohomish or Kirkland home under mature trees can be full again by Thanksgiving. Here is the schedule we suggest, what to check while you are up there, and when to stop doing it yourself.
Why One Cleaning Is Not Enough Here
The problem is timing. Firs shed needles steadily from August onward, and every wind event knocks down more. Needles are the worst debris a gutter can hold: they pass through most screens, mat into a dense layer that holds water, and break down into a sludge that plugs downspout outlets. Then the maples drop, often most of the tree in a single week after a frost or a windy night. By the time the November windstorms arrive, a gutter cleaned in September is carrying a wet mat of needles and leaves, and the water goes behind the fascia instead of down the spout.
A Fall Cleaning Calendar for Puget Sound
Late September. Clear the summer needle load and confirm every downspout flows before the first atmospheric river arrives. The gutters are dry, so this is also the best time to spot problems.
Late October to early November. After the maples drop. This is the most important cleaning of the year. You want the gutters clear before the mid-November windstorms and the heaviest rain of the season.
December, after the big blows. The November storms strip the last of the needles and bring down twigs. A quick check and clean sets the gutters up for the rest of the winter.
Spring. Fir cones, blossoms, and the pollen crust that forms after a dry spell. Less urgent, but worth a look.
Homes under heavy canopy, like many in Lake Stevens or on the Issaquah slopes, may need an extra pass. Homes on open lots in newer neighborhoods may get by with two.
What to Check While You Are Up There
Cleaning is also the best chance to inspect. Take a few extra minutes for these.
- Downspout flow. Run a hose into the gutter and confirm water comes out the bottom at a good rate. A slow trickle means a clog in the elbow or the underground drain.
- Standing water. If water pools in a section after the rest drains, the gutter has lost its pitch. Look for sagging hangers or a fascia board that is no longer straight.
- Granules. A layer of coarse sand in the gutter is shingle granules. A little is normal on a new roof. A lot on an older roof means the shingles are wearing.
- Seams and end caps. On sectional gutters, every seam is a place to leak. Look for rust lines, drips, or daylight.
- Fascia behind the gutter. Press on it. Soft wood or peeling paint means water has been going over the back edge.
- The roof edge. Look for a drip edge directing water into the gutter, and for shingles that overhang the right amount. Check the lowest courses for moss.
When to Stop Doing It Yourself
We will be direct. Gutter cleaning sends a lot of people to the emergency room every fall, almost always from ladders. Do not clean gutters on a two-story home from a ladder. Do not set a ladder on soft wet ground, on a deck, or anywhere near a power line. Do not walk a roof that is wet, and in November they are all wet. Fir needles on a damp roof are as slick as ice.
If you cannot reach the gutter from a ladder set on firm, level ground with someone footing it, hire the work out. A gutter cleaning costs far less than a fall does.
How Seamless Gutters and Guards Change the Schedule
Two things change the math. Extruded seamless gutters are formed on site to the exact length of each run, so there are no seams to leak or snag debris and the pitch is set correctly at installation. The cleaning schedule does not go away, but each cleaning is faster and the gutter is far less likely to fail between them.
Gutter guards, which we offer as an optional upgrade, keep needles on top where wind and rain move them along. Under firs, that can turn three cleanings into a quick visual check of the guard surface once or twice a season. They are not maintenance-free, but they are a real reduction.
Let Us Check the Whole System
If your gutters are sagging, leaking at the seams, or overflowing behind the fascia no matter how often you clean them, it may be time to look at replacing them rather than cleaning them again. Premier Roofing NW installs and repairs extruded seamless gutters across the Greater Puget Sound area, from Everett and Snohomish to Bellevue and Kent, and our inspections and estimates are free. Discounts are available for seniors, military, and first responders. Call us at (425) 247-0088 and we will make sure your gutters are ready for the maples.
