Fall Gutter Cleanout Checklist for Front Range Homes

Fall gutter cleaning works best in a narrow window: after the trees are bare and before the gutters freeze. Clean too early and the last leaves fill the trough right back up. Wait too long and those wet leaves freeze into a block that keeps meltwater from reaching the downspout.

On the Front Range those two dates don't always line up, so watch the forecast for a dry, calm stretch in late fall. If your lot has heavy tree cover, plan on two passes: one when most of the leaves are down and another after the last of them.

The freeze is the real deadline. A packed gutter can't drain when snow melts, so water sheets over the edge and refreezes, and the weight of that ice pulls hangers loose. A February thaw-and-freeze cycle can rip a neglected gutter right off the fascia.

Nearly every step here happens up on a ladder, so the setup matters more than the scooping. Run through these before you climb:

Wear gloves and hang a bucket from the ladder or lay a tarp below. Clear the area around each downspout outlet first, then work away from it so loose debris doesn't get shoved down the downspout. A plastic scoop gets the muck out without scratching the gutter.

Once a run is empty, put a hose at the far end and let it flow. Water should move steadily toward the downspout. If it pools in one stretch, that section has lost its pitch or is sagging between hangers, and the standing water there is what freezes first.

While the water runs, look for drips at the corners, end caps, and outlets. On older sectional gutters, check every joint as well, since each one is a spot that can drip or split in a freeze.

If you already have guards, this step shrinks to rinsing the top surface and making sure every section is still seated and fastened.

Feed the hose into the top of each downspout and let it run. Water should come out the bottom about as fast as it goes in. If it backs up into the gutter instead, there's a clog, most often at an elbow.

Pull the extension or the bottom elbow off and clear what you can reach by hand. Running the hose up from the bottom will often push the rest loose. Check every downspout, even the ones that looked fine in September, because a half-plugged downspout can freeze solid in the first real cold snap.

With the gutters clean, look at what holds them up. Hidden hangers are screwed through the gutter into the fascia board, and snow and ice loosen them over time. Snug any screws that have backed out.

While you're at it, watch for a gutter sagging between hangers, peeling paint on the fascia, a soft spot when you press the board, or water stains on the soffit below. Any of those can point to soft wood behind the gutter, and that's a repair to make before winter hangs ice on it.

Last, walk around the house and check each downspout extension before the ground freezes:

Once guards are on, most of the scooping drops off this list, and the trees around your house decide which kind fits. If the cleanout turned up a sagging run or a soft spot in the board, that gets fixed before any guard goes on.
