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.
There is no city leaf-season sweeping program here, and the twice-yearly brush pickup explicitly excludes leaves, bark and fir needles. What comes off your roof is yours to handle.

Why University Place is harder than the advice you will find
detached homes in University Place, and 92% of them have a roof moss grows on — composition shingle or wood shake.

City of University Place, Shoreline Master ProgramAlmost every gutter article you will read says “spring and fall.” That advice was written for maple country, and University Place 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 University Place 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). There is no leaf-season sweeping program in University Place, so the calendar below is the whole of it.
What is actually going through them
More than most people picture, and we can be specific about University Place rather than guessing. Across 5,409 pre-1990 University Place homes with a moss-susceptible roof, the median roof footprint is about 1,390 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 | 866 gal |
| November alone | 6.68 in | 5,800 gal |
| November – January | 18.13 in | 15,700 gal |
| Full year | 39.22 in | 34,000 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. University Place 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 University Place, 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.
What goes down a storm drain in University Place is not treated. The city says so plainly: it empties into ditches, creeks, ponds or Puget Sound. UPMC § 12.10.030 allows routine external building washing only where no detergents are used, and the city names power washing among the activities that should not be allowed to drain into the storm system. There is no municipal leaf sweeping to catch what ends up in the street, and the curbside brush pickup will not take needles.
- 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
