How to clear a clogged downspout yourself 2

A clogged downspout can hide behind a gutter that looks perfectly clean. Water backs up, spills over the eaves, and lands against the foundation. This guide shows how to find and clear the clog from the ground, handle buried drain lines, and know when to call a pro.

**TLDR:** Start at the bottom of the downspout, not the top of a ladder. A garden hose test from the ground usually finds the clog, often in an elbow. Clear it with water, a drain snake, or by taking the elbow apart, then flush the run. Do it before hard freezes turn a clogged downspout into an ice plug.

---

The gutters got cleaned last month. Then a hard November rain hits, and water still pours off one corner like an open faucet.

That usually points below the gutter. In Southwest Missouri, late oak and hickory leaves pack into downspout elbows right before the first freezing nights.

Here is how to unclog a downspout safely. For the bigger picture, our guide to [how gutters, downspouts and splash blocks work as one system](https://teagueroofingplus.com/gutters-and-downspouts-care-springfield/) covers drainage from roof edge to yard.

## Signs You Have a Clogged Downspout

A clogged downspout sends water the wrong way. It spills over the gutter, sprays from a seam, or barely trickles out the bottom.

Watch the system during a steady rain, then use this table to decide where to look first.

What you see What it usually means Check first

Overflow at one corner only The downspout below it is blocked Bottom elbow, then top elbow

Weak trickle in heavy rain A partial clog of packed leaves Both elbows

Water spraying from a joint Backed up water forcing through The section below the leak

Yard emitter never pops open The buried line is blocked The emitter, then the connector

In our experience, clogs usually show up in three places: the downspout bends, the gutter outlet, and the underground lines. Start with the elbows.

> **Tip:** Tap the downspout from top to bottom with your knuckles. An open pipe sounds hollow, and a packed section sounds dull.

## Why Fix a Downspout Clog Before Freezing Weather?

A downspout clog that is a nuisance in October becomes a real problem below freezing. Trapped water turns into an ice plug, and the gutter above it has nowhere to drain.

Water then spills over the gutter onto the foundation, or backs up and soaks the roof edge. Ice in the trough is also part of [how ice dams form along the roofline](https://teagueroofingplus.com/ice-dam-prevention-southwest-missouri/).

The [IBHS Winter Weather Ready guide](https://ibhs.org/ibhs-news-releases/ibhs-winter-weather-ready-guide-provides-easy-to-do-actions-to-help-prevent-property-damage-from-colder-temperatures/) tells homeowners to clear debris from gutters and downspouts so water flows away from the home. Our post on [getting gutters ready for freezing temperatures](https://teagueroofingplus.com/prepare-gutters-for-freezing-temperatures/) covers heating cables and the rest of the freeze list.

> **Important:** Do not chip or pound ice out of a frozen downspout, because you can split the seams. Wait for a thaw, then clear it.

## Tools and Ladder Safety Before You Start

Most downspout clogs clear from the ground with a garden hose, work gloves, a screwdriver and a hand drain snake. A ladder only comes out when the clog sits at the gutter outlet.

Skip the pressure washer, since high pressure can split seams and pack a soft clog tighter.

If you need a ladder, the [U.S. Consumer Product Safety Commission](https://www.cpsc.gov/Newsroom/News-Releases/2021/Consumers-Should-Spring-into-Safety-with-the-New-Normal) advises solid, level ground, another adult on site as a spotter, and distance from power lines. Never lean a ladder on the gutter. We are roofers, not safety trainers, so follow your ladder’s warning labels too.

> **Important:** If the clog sits at the top of a two story downspout, stop at the ground level steps. That height turns a simple fix into a fall risk.

## How to Unclog a Downspout, Step by Step

Work from the bottom up and let water show you where the clog is, since many clogs clear without a ladder.

1. **Remove** the extension or splash block and clear what you can reach in the bottom elbow.
1. **Push** a garden hose up into the downspout. Water that backs out right away means the clog sits low.
1. **Tap** along the pipe to find the dull, packed section.
1. **Unscrew** the bottom elbow and knock the debris into a bucket.
1. **Feed** a drain snake into any section that stays blocked, cranking as you push.
1. **Reassemble** each piece with the upper section tucked inside the lower one, so joints do not leak.
1. **Flush** the full run with the hose and confirm strong, steady flow at the bottom.

### If the clog sits at the gutter outlet

Scoop the outlet clear, then run the hose down from the top. If the gutter is full too, our guide to [how often gutters need cleaning before winter](https://teagueroofingplus.com/gutter-cleaning-before-winter-springfield/) covers timing.

> **Pro tip:** Flush each downspout again after the last big leaf drop. Heavy oak cover can refill a pipe within weeks.

## How Do You Clear an Underground Downspout Drain?

Start at the far end of the line. Check the pop-up emitter in the yard, then work back toward the house with water and a drain snake.

A pop-up emitter is a cap at the end of a buried line that pops open when water flows.

Not every buried line ends in your yard. The [U.S. Environmental Protection Agency](https://www.epa.gov/soakuptherain/soak-rain-disconnect-redirect-downspouts) notes that some downspouts tie into the sanitary sewer or storm drain system. It urges homeowners to consider local rules before redirecting them, so check with your city first.

Most buried line clogs clear with water and a snake. Here is where a DIY fix on an underground downspout drain should stop.

Problem First step Stop and get help when

Emitter stays shut in heavy rain Clear grass and mud from the cap Water never reaches the emitter

Backup at the downspout connector Disconnect and snake the line The snake hits a hard stop

Soggy ground along the line Mark the spot and stop flushing Right away, the pipe may be cracked

Line clogs again within weeks Look for roots near the line It happens a second time

Crushed pipe, roots and sags need digging, not a snake.

> **Tip:** A leaf strainer where the downspout meets the buried line catches debris above ground, where it is easy to reach.

## When a Clogged Downspout Is Beyond DIY in Southwest Missouri

Get help when the clog keeps returning, the pipe is damaged, or the work sits above the first story. A crushed, separated or undersized downspout points to a repair or replacement, not a cleaning.

Situation Who handles it Why

Clog in a ground level elbow DIY Hose and snake work from the ground

Clog atop a two story run Hire it out The ladder risk outweighs the fix

Downspout crushed or separated Gutter repair It needs new parts or replacement

Same downspout clogs often Gutter repair Sizing or placement may be off

A repeat downspout clog may mean the outlet is too small for the roof area above it. We do not clean gutters or clear clogs, but we do replace gutters and downspouts through our [gutter repair across Southwest Missouri](https://teagueroofingplus.com/gutter-repair-southwest-missouri-teague-roofing-plus/). Shingle granules piling up in an elbow call for a free roof inspection.

> **Illustrative scenario:** A family weighing [gutter installation in Battlefield](https://teagueroofingplus.com/locations/gutter-installation-battlefield-mo/) sees water pour over one back corner after every storm. Before buying anything, they run a hose test. Water backs out of the bottom elbow within seconds. The elbow gives up a wad of wet oak leaves, and the corner drains normally again.

## Frequently Asked Questions

**What is the fastest way to unclog a downspout?**

Push a garden hose up into the downspout from the bottom. Water that backs out right away means the clog sits in the bottom elbow. Try the hose test on the next dry day.

**Can I use a pressure washer on a clogged downspout?**

No. High pressure can split seams and pack a soft clog tighter. Reach for a garden hose and a hand drain snake instead.

**How do I know if the clog is in the gutter or the downspout?**

Watch the water during a steady rain. If one corner overflows while the rest drains, the downspout below that corner is the likely problem. If the whole run overflows, check the gutter itself next.

**Why does my underground downspout drain emitter stay shut?**

Grass, mud or debris may hold the cap down, or the line behind it may be blocked. Lift the cap, clear around it, and run a hose into the downspout. If water never reaches the emitter, have the line checked.

**Can a downspout clog lead to ice dams?**

It can add to the problem. A blocked downspout leaves standing water in the gutter, and that water freezes along the eaves. Clear clogs before the first hard freeze.

**What should I do if my downspout is frozen solid?**

Leave it alone until it thaws. Chipping at it can split seams or knock it loose from the wall. Flush it once it thaws, before the next cold snap.

**How often should I check for a clogged downspout?**

Check after the last leaves fall, after big spring storms, and whenever one corner overflows. A hose test takes minutes. Add it to your fall and spring routines.

**Do downspout screens or strainers help?**

They catch leaves before they reach the elbows or a buried line. Debris still collects on top, so they need regular cleaning. Clear them each time you clean the gutters.

**What causes a repeat downspout clog?**

It may be undersized for the roof area it drains or sit under heavy tree cover. A dent or a sag in a buried line can also trap debris. Ask a gutter pro to look at sizing and placement.

## Key Takeaways

- **Start at the bottom:** A hose pushed up from below shows where the clog sits.
- **Use gentle tools:** A hose and a hand drain snake handle most clogs.
- **Respect the ladder:** Solid, level ground and a spotter come first.
- **Check buried lines from the far end:** Know where the line ends before you change it.
- **Beat the freeze:** A clogged downspout in October becomes an ice plug in December.
- **Spot the repair:** Repeat clogs and damaged pipe point to sizing or hardware.

Try the hose test on the next dry day."}},{"@type":"Question","name":"Can I use a pressure washer on a clogged downspout?","acceptedAnswer":{"@type":"Answer","text":"No. High pressure can split seams and pack a soft clog tighter. Reach for a garden hose and a hand drain snake instead."}},{"@type":"Question","name":"How do I know if the clog is in the gutter or the downspout?","acceptedAnswer":{"@type":"Answer","text":"Watch the water during a steady rain. If one corner overflows while the rest drains, the downspout below that corner is the likely problem. If the whole run overflows, check the gutter itself next."}},{"@type":"Question","name":"Why does my underground downspout drain emitter stay shut?","acceptedAnswer":{"@type":"Answer","text":"Grass, mud or debris may hold the cap down, or the line behind it may be blocked. Lift the cap, clear around it, and run a hose into the downspout. If water never reaches the emitter, have the line checked."}},{"@type":"Question","name":"Can a downspout clog lead to ice dams?","acceptedAnswer":{"@type":"Answer","text":"It can add to the problem. A blocked downspout leaves standing water in the gutter, and that water freezes along the eaves. Clear clogs before the first hard freeze."}},{"@type":"Question","name":"What should I do if my downspout is frozen solid?","acceptedAnswer":{"@type":"Answer","text":"Leave it alone until it thaws. Chipping at it can split seams or knock it loose from the wall. Flush it once it thaws, before the next cold snap."}},{"@type":"Question","name":"How often should I check for a clogged downspout?","acceptedAnswer":{"@type":"Answer","text":"Check after the last leaves fall, after big spring storms, and whenever one corner overflows. A hose test takes minutes. Add it to your fall and spring routines."}},{"@type":"Question","name":"Do downspout screens or strainers help?","acceptedAnswer":{"@type":"Answer","text":"They catch leaves before they reach the elbows or a buried line. Debris still collects on top, so they need regular cleaning. Clear them each time you clean the gutters."}},{"@type":"Question","name":"What causes a repeat downspout clog?","acceptedAnswer":{"@type":"Answer","text":"It may be undersized for the roof area it drains or sit under heavy tree cover. A dent or a sag in a buried line can also trap debris. Ask a gutter pro to look at sizing and placement."}}]}],"@id":"https:\/\/teagueroofingplus.com\/how-to-clear-a-clogged-downspout\/#schema-164930","isPartOf":{"@id":"https:\/\/teagueroofingplus.com\/how-to-clear-a-clogged-downspout\/#webpage"},"publisher":{"@id":"https:\/\/teagueroofingplus.com\/#organization"},"inLanguage":"en-US","mainEntityOfPage":{"@id":"https:\/\/teagueroofingplus.com\/how-to-clear-a-clogged-downspout\/#webpage"}}]},{"@context":"https:\/\/schema.org","@type":"WebPage","name":"How to Clear a Clogged Downspout Yourself","url":"https:\/\/teagueroofingplus.com\/how-to-clear-a-clogged-downspout\/","speakable":{"@type":"SpeakableSpecification","cssSelector":["#tldr-summary"],"xpath":["\/\/*[@id=\"tldr-summary\"]"]},"description":"Start at the bottom of the downspout, not the top of a ladder.
