How often should you clean your gutters?
Updated July 2026
Clean your gutters twice a year: once in late spring (seed pods, blossoms, storm debris) and once in late fall after the leaves are mostly down — that second date is the one that prevents ice dams. Homes under heavy tree cover, especially pines (which shed needles year-round), should clean quarterly; a treeless lot can often get away with an annual clean plus checks after big storms.
What changes the interval
| Your situation | Interval | Why |
|---|---|---|
| Few or no mature trees nearby | Once a year + after major storms | Shingle grit and wind-blown debris still accumulate, just slowly |
| Typical suburban lot, deciduous trees | Twice a year | Spring for seeds and blossoms; late fall after leaf drop |
| Heavy tree cover or overhanging branches | Quarterly | Gutters can clog in a single windy week under a full canopy |
| Pine trees nearby | Quarterly | Needles shed continuously and mat into a felt that water can’t pass |
| Gutter guards installed | Inspect yearly, clean every 2 years | Guards slow debris, they don’t stop it — and the tops need brushing off |
| Snow country | Always clean after leaf drop, before first snow | A leaf-packed gutter is the starter kit for an ice dam |
The cost of skipping it
What skipping it costs: water that can't travel the gutter goes where you least want it — over the back edge into fascia and soffit (rot repairs $500–2,500), or straight down beside the house, where soil saturation leads to basement leaks and foundation repairs from $1,000 to well past $5,000. In winter, clogged gutters are the #1 contributor to ice dams: $1,000–3,000 for removal plus interior ceiling repairs. A pro cleaning runs $160–450; DIY costs a Saturday morning.
How to do it (2–3 hours DIY · or $160–450 pro)
- Pick a dry day and use a sturdy ladder with a standoff; work with a helper footing the ladder. (Two-story homes with steep terrain: this is a legitimately good job to hire out.)
- Scoop debris into a bucket with a gutter scoop or gloved hands — work away from the downspout.
- Flush the gutter toward the downspout with a hose and confirm water actually exits at the bottom.
- Clogged downspout: feed the hose up from the bottom at full pressure, or use a plumber’s snake.
- Check slope while water runs (standing puddles mean a sagging hanger) and confirm extensions carry discharge 4–6 ft from the foundation.
Knowing the interval is the easy half. OnOtto reminds you at the right interval — and won't let you snooze it into next year. Tasks persist until they're done, and completing both gutter cleanings schedules the next one automatically.

Are gutter guards worth it — do they end cleaning forever?
Good micro-mesh guards cut cleaning frequency dramatically, but "never clean again" is marketing. Guard tops still collect debris that needs brushing off, fine material (pine needles, shingle grit, seeds) still gets through cheaper guards, and the system still needs a yearly look. Fair math: guards turn a quarterly chore under trees into an annual inspection — worth it for high or complex rooflines.
What are the signs my gutters are clogged right now?
Water sheeting over the edge in rain, plants sprouting from the trough, sagging sections, staining on the siding below, and in winter, icicles along the gutter line — icicles are the visible edge of an ice-dam setup. Any of these: clean now rather than at the next scheduled date.
When exactly should the fall cleaning happen?
After your trees are ~80% bare but before the first hard freeze or snow — early-to-mid November in much of the US. Clean too early and the rest of the leaves refill the gutter; too late and you're chipping frozen mats. It pairs naturally with the rest of the fall checklist.
Can clogged gutters really damage the foundation?
Yes — it's the most expensive failure mode. A clogged gutter turns the roof (often 1,500+ sq ft of catchment) into a waterfall landing beside the footing. Season after season, that cycle of saturation and drying settles slabs, leaks basements, and in clay soils moves foundations. Downspout extensions plus clean gutters are the cheapest foundation insurance there is.
