Fall Leaf Season in Sacramento: Keeping Gutters Clear

By Sacramento Gutter Repair & Install · September 14, 2026 · 5 min read

There's a rule of thumb from the rest of the country that says clean your gutters in October, before the winter weather. In Sacramento that's exactly wrong. October is when the gutters are full of summer dust and fire-season ash and almost nothing else; the leaves haven't started. Clean them then and you'll be doing it again in December, when they're full of sycamore, and again in February, when they're full of liquidambar balls. The City of Trees has its own calendar, and it runs late.

The trees, and when they drop

Sacramento's street trees were planted in waves, and the wave decides your gutter schedule.

London plane (sycamore). The tall, mottled-bark trees over the streets in Land Park, East Sacramento, Curtis Park, Midtown and the Fab 40s. Leaves the size of a dinner plate, dropping from mid-November through January — they hang on stubbornly and come down over three months instead of three weeks. The fuzzy seed balls break up in spring into fibers that get through anything coarse. Worst gutter tree in the city.

Liquidambar (sweetgum). Planted by the thousand in the 1960s and 70s subdivisions of Arden-Arcade, Carmichael, Citrus Heights and Rancho Cordova. Star-shaped leaves in late November, then the spiked seed balls from December through February. The balls don't blow off; they roll to the low spot in the gutter and stack up at the downspout.

Valley oak and interior live oak. Carmichael, Fair Oaks, Folsom, Roseville, Rocklin. Small leaves through November, acorns in October and November, catkins in April. The acorns are heavy: a gutter full of wet acorns under a big valley oak can outweigh its hangers.

Elm. The Dutch elm survivors in East Sacramento, Land Park and around Davis. Small leaves, early — October into November — in enormous quantity.

Modesto ash, mulberry, Chinese pistache. Common in the 1950s–70s neighborhoods. One big drop in November, done by Thanksgiving. Easy.

Redwood. The front-yard redwoods planted as saplings in Arden-Arcade, Fair Oaks and Carmichael in the 1960s are now eighty feet tall. Needles all year, heaviest in late summer. A redwood gutter in September is already full.

Camphor and magnolia. Evergreen, dropping a little every week of the year in East Sacramento and Land Park. There's no clean window.

The cleaning calendar

The first real storm usually comes in the first half of November, before the main drop. That's fine if the gutters weren't full of summer debris; it's the reason the September walk-around exists. The point is that cleaning is a December job here, not an October one.

What actually clogs

It isn't the leaves so much as where they go. Leaves slide to the low spot in a run — which on a 1960s house with backed-out spike hangers is the middle — and pack at the downspout outlet. One handful of wet plane leaves over a 2x3 outlet stops the run. A 3x4 outlet passes it. That's most of why we upsize downspouts on every replacement: not for capacity, but so the outlet is bigger than the wad.

Buried drain lines make it worse. On the older homes the downspout drops into a pipe under the lawn, and every leaf that gets past the outlet ends up in that pipe. After a few decades the pipe is done. A downspout that gushes at the top and won't drain in a storm is usually the line, not the gutter.

Guards, by tree

Guards are worth it here under the trees that force two or three cleanings a year, and not under the ones that drop once and stop.

• Micro-mesh (stainless, $12–$22 a foot): the only guard that handles redwood needles, oak catkins and plane-tree fibers. Worth it under redwoods, oaks, London planes and camphors.
• Aluminum screen ($6–$11 a foot): stops liquidambar balls, ash, mulberry and elm leaves at a fraction of the price. Fine under the 1970s subdivision trees.
• Reverse-curve ($22–$35 a foot): the hooded type. Plane fibers ride around the lip and it can overshoot in the heaviest hour of a storm. Rarely our first pick here.

The gutter guards page has more on each type. Guards on a gutter that's pitched wrong or hung behind a tile lip won't help; the gutter has to work first.

If you're doing it yourself

Single-story, shingle roof, a good ladder and someone holding it. Gloves, a bucket on a hook, and flush every downspout from the top when you're done. Stop if the roof is two stories, if it's tile — walking on concrete tile cracks it — or if the ladder has to lean on the gutter. Gutter cleaning is $140–$350 by home size, and the December visit comes with a ladder check of the hangers and fascia, which under a valley oak is worth as much as the cleaning.
