Why Seattle gutters clog faster than most
Most of Seattle's rain falls between October and April, as long stretches of steady drizzle broken up by the occasional heavy storm. Gutters have to carry that water for months on end, and three local sources keep filling them:
- Douglas fir and cedar needles. Small, constant and year-round. They mat together into a sludge that slows water even when the gutter looks only half full.
- Bigleaf maple and other deciduous leaves. The bulk comes down in October and November, often right as the heavy rain starts.
- Roof moss and shingle grit. Moss clumps break loose in storms and wash into the gutter along with asphalt granules, which settle into heavy sediment at the bottom.
In a drier climate a clogged gutter overflows a few times a year. Here it can overflow on every rainy day for months, soaking the soil beside the foundation, staining siding and rotting fascia boards.
What a gutter cleaning usually includes
- Removing debris from every gutter run, and bagging it rather than dumping it on lawns and beds
- Flushing downspouts and clearing the elbows, where needles tend to jam
- Checking that water runs toward the downspouts instead of pooling in low spots
- Pointing out loose hangers, leaking seams or sections pulling away from the fascia
- Optional add-ons to ask about: roof debris blow-off, gutter guard cleaning or installation, seam sealing and hanger repairs
Scope varies by provider, so ask what's included when you get your quote, especially whether downspouts are flushed and whether the debris is hauled away.
How often to clean gutters in Seattle
- Few or no trees nearby: once a year, in late fall after the leaves are down.
- Maples, alders or fruit trees: twice a year: late fall, plus spring to clear seed pods, catkins and blossoms.
- Firs or cedars over the roof: two to three times a year. Needles drop all year, and a late-summer check catches build-up before the first fall storms.
Signs you need it sooner: water sheeting over the front edge in a rainstorm, plants or moss growing in the gutter, dark streaks down the siding, or a downspout that stays dry in a downpour.
Underground drain lines and downspouts
Many older Seattle houses have downspouts that run into underground drain pipes instead of onto splash blocks. When needles and grit wash down, those pipes can clog out of sight, and water backs up and spills out the top of the downspout. If you've seen that, mention it in your request. Clearing a buried line is a different job from cleaning gutters, and not every gutter cleaner does it.
What affects the cost of gutter cleaning
There's no honest one-size price, which is why your quote is free and specific to your home. Providers typically price on:
- Linear feet of gutter and the number of downspouts
- Number of stories and roof pitch; a steep or three-story roof needs more setup and safety gear
- How much debris there is and how long it's been since the last cleaning
- Access: slopes, decks, landscaping or tight side yards where the ladder has to go
- Gutter guards, which often have to come off and go back on to clean underneath
- Add-ons such as roof blow-off, downspout repairs or debris haul-away
If your roof also has moss, ask about doing roof moss removal on the same visit, since that moss is headed for your gutters anyway.
Gutter guards in a needle-heavy climate
Guards help, but none are maintenance-free under conifers. Fine fir needles slip through wider screens and pile up on top of solid "reverse curve" covers, and micro-mesh guards can collect a film of needle bits and pollen that makes water shed over the edge. Plan on occasional cleaning of the guards themselves, and ask the provider which style holds up best under your particular trees.
