The short version. Book the main clean any time from late October through January — once the needle drop is under way and before the wettest stretch has done its worst. Late November into December is the sweet spot, but the season is wide. Under mature Douglas fir on a north-facing lot, book twice: one in the autumn, one in spring.
The city runs its own sweeper through the fall and asks residents not to blow debris into the street, because plugged storm drains are what floods Fircrest.

Why Fircrest is harder than the advice you will find
detached homes in Fircrest, and 90% of them have a roof moss grows on — composition shingle or wood shake.

City of Fircrest Public WorksAlmost every gutter article you will read says “spring and fall.” That advice was written for maple country, and Fircrest is not maple country. Douglas fir and western red cedar shed needles, and needles behave nothing like leaves: they do not blow off a roof in a gust, they knit into a mat in the valleys and then slide into the gutter all at once.
The USDA Forest Service measured Douglas fir litterfall across thirteen years. The drop peaks in October, about half the annual load falls in October and November, and the minimum is April — which is exactly when the standard advice sends you up a ladder.
The Fircrest calendar
Douglas fir litterfall (USDA Forest Service PNW-14) against monthly precipitation for Tacoma No. 1, the nearest long-record NOAA station (NOAA 1991–2020). Fircrest runs its own street sweeper through the fall, but the city is explicit that keeping leaves off the grates is the resident’s job.
What is actually going through them
More than most people picture, and we can be specific about Fircrest rather than guessing. Across 1,552 pre-1990 Fircrest homes with a moss-susceptible roof, the median roof footprint is about 1,347 square feet — recorded floor area divided by story count, because rain falls vertically and a steeper roof does not catch more of it.
| Period | Rainfall | Through the gutters |
|---|---|---|
| One inch of rain | 1.00 in | 839 gal |
| November alone | 6.50 in | 5,500 gal |
| November – January | 18.55 in | 15,600 gal |
| Full year | 40.81 in | 34,200 gal |
Footprint is recorded floor area divided by story count, from the county tax roll; gallons are footprint × inches × 0.623. An attached garage is not carried in floor area, so treat these as a floor rather than a ceiling. Fircrest is unusual in that the figure barely moves with the number of stories — its two-story homes are larger inside but sit on a slightly smaller footprint.
When that cannot get through, it goes over the front edge and lands in a narrow strip against the foundation — at the time of year the ground is already saturated and least able to take it. The Department of Energy’s guidance is to discharge at least five feet out from the foundation for exactly this reason, and Washington is crawl-space country: moisture under the floor does not stay under the floor.
Where the debris goes
In Fircrest, debris handling is part of the job. Gutter debris cleared by hand, bagged, and taken away on the truck stays out of the street and out of the storm drains — and here that matters more than in most places.
Fircrest is small enough that its drainage has no slack in it: 535 catch basins, 22 miles of pipe and fourteen outfalls into the Leach Creek holding basin, which discharges to Leach Creek and on to Chambers Creek and Puget Sound, with salmon spawning habitat starting just downstream. The city puts it plainly in its own newsletter — plugged storm drains are the leading contributor to flooding streets in the City — and asks residents not to blow leaves and yard debris into the road.
- Debris cleared by hand, bagged, and taken away on the truck — keeping it out of the downspouts and out of the storm drains
- Downspouts checked and cleared, all the way through to the outlet
- Flow tested with water once the debris is out
- Fasteners and pitch checked — gutters should fall at least a sixteenth of an inch per foot toward the outlet
- Roof valleys cleared of needle build-up, which is where the next gutter-full comes from
- Discharge point confirmed — water landing well clear of the foundation, not beside it
