Short answer: clean your gutters at least once every fall — and if your home sits under evergreens, make it twice a year, fall and spring. Western Washington's combination of heavy rainfall and year-round needle drop means gutters here fail faster and cost more when ignored than in almost any other region.
Why our region is different
Gutter advice written for the rest of the country assumes one autumn leaf-drop and a dry summer to forgive missed maintenance. The Puget Sound offers neither. Our rain arrives for eight months straight, and the firs and cedars over Woodinville, Sammamish, and Redmond homes shed needles continuously — needles that mat into dense plugs no amount of rain will flush through.
The real schedule, by property type
- Open, sunny lots: once a year, in fall after leaf-drop.
- Under evergreens: twice a year — fall and spring. This is most of the Eastside.
- Heavy canopy or moss-prone roofs: twice a year plus a check after major windstorms, which load gutters in a single afternoon.
What skipping it actually costs
A clogged gutter doesn't just overflow forward onto your flowerbeds — it backs up under the roof edge. That's the path to rotted fascia boards, soaked soffits, stained siding, and in heavy rain, water finding its way inside. When we tear off roofs across the region, the rot we find at the eaves almost always tells a gutter story. It's the cheapest expensive problem in home maintenance: a routine cleaning versus carpentry.
Pair it with the roof
Moss debris is a major gutter clogger, which is why gutter cleaning and roof cleaning belong in the same visit — one crew handling the entire drainage path, from shingles to downspout outlet. We check fascia, drip edge, and hangers while we're there, and fix small gutter issues on the spot.
One visit each fall is the habit that protects everything downstream. Free estimates across the Greater Puget Sound: (425) 270-1525.
