Twice a year, minimum
At least twice a year: once in late fall after the leaves drop, and once in early spring before the heavy rains. Homes under heavy tree cover may need it every couple of months during shedding season, and you should always check after a major storm.
Gutters have one job: move roof water away from the house. When they fill with leaves and grit, the water goes where you least want it instead, against your siding and down toward your foundation. The damage is slow and hidden until it is not, which is why gutters tend to get attention only after a ceiling stain or a wet basement shows up.
Twice a year is the baseline for most homes. If you have big deciduous trees overhead, treat that as a floor rather than a rule and check more often during the months things are actually falling.
How to do it
- Pick a dry day and set a sturdy ladder on level ground. Never lean the ladder against the gutter itself.
- Wear work gloves and eye protection, and have someone nearby or at least aware you are working at height.
- Starting near a downspout, scoop leaves and sediment into a bucket rather than flinging it onto the roof or lawn.
- Work along the run away from the downspout, then back toward it, clearing as you go.
- Flush the gutter with a garden hose from the far end so the water carries fine debris toward the downspout.
- Send the hose into the top of the downspout to confirm it drains freely. If water backs up, clear the clog with a plumber's snake.
- Confirm the water actually flows to the downspout with no standing pools, which means the pitch is right.
- Check the hangers, seams, and end caps for damage while you are up there, and fix anything loose before the next storm.
Common mistakes
- Doing only the fall cleaning and skipping spring. Winter debris can block downspouts right before the summer rains arrive.
- Stepping onto the roof to reach a section instead of moving the ladder. Reposition the ladder; it is not worth the fall risk.
- Assuming gutter guards mean you never have to look again. No guard is maintenance-free; debris still collects on top or slips through.
This is exactly the kind of thing that is easy to know and easy to forget. Adulting can put it on a cadence so it surfaces when it is next due, instead of when something goes wrong. Free to start.

Questions people ask
- What does a clogged gutter actually do?
- Water overflows against the fascia, siding, and foundation instead of draining away, which leads to rot, basement leaks, and foundation damage. In winter the trapped water freezes into ice dams that can tear the gutters off the roofline.
- Is there an official standard for how often?
- No US agency sets a gutter-cleaning interval. Twice a year is consistent guidance across home-maintenance and consumer sources, adjusted up for heavy tree cover or storms.
