How do I know if tree roots are in my sewer line?

The clearest sign is a main line clog that comes back every few months, in a yard with large trees. Slow drains through the whole house, gurgling toilets and a backup in the basement floor drain point the same way. A camera inspection confirms it, because roots show up as a hairy mat inside the pipe.

How tree roots get into a sewer lineA tree’s roots spread through the soil looking for water. Where the sewer pipe has a leaking joint or crack, small roots slip inside and grow into a mat that catches paper and waste. Where the pipe is sound, the roots stay outside.TreeRoots slip in at a leaking joint or crackInside, they grow into a mat that catches paper and wasteSound pipeRoots stay outsideRoots follow moisture
  • Clogs that return weeks or months after the line was cleared
  • Slow drains all over the house, not just one sink
  • Gurgling toilets when water drains elsewhere
  • A backup in the lowest drain, often after laundry or showers
  • Worse in late summer and fall, when dry soil sends roots looking for water
  • Big trees near the line, such as cottonwoods or willows

Roots are a sign of a pipe problem, not the cause

Tree roots don’t break a sound sewer pipe. They follow moisture through the soil, and when they reach a joint that has pulled apart or a small crack that leaks, fine roots slip inside. With steady water and nutrients, they grow into a dense mat that catches paper and waste.

Roots get in through a crack or joint, then fill the pipe.

That’s why roots come back after the line is cleared. Cutting removes the mat, but the opening is still there. In older clay pipe, with a joint every few feet, there can be many openings. A camera inspection after clearing shows exactly where the roots are getting in.

Which trees cause sewer damage in Greeley?

Any tree can send roots into a leaking pipe, but some go looking for water harder than others. Ash trees alone make up around 15% of Greeley’s urban forest. These are the ones to watch near your sewer line:

  • Cottonwood and poplar Large, thirsty trees with wide-spreading roots. A common cause in older Greeley yards.
  • Willow Roots seek out water aggressively and grow fast in moist soil.
  • Silver maple Shallow, spreading roots that find leaking joints quickly.
  • Ash Common on Greeley streets and yards, with roots that travel toward moisture.
  • Elm Siberian elm in particular grows fast and spreads its roots wide.
  • Boxelder and locust Hardy trees whose roots can reach a sewer line from across the yard.

Planting something new? City of Greeley rules say trees aren’t to be planted within 10 feet of either side of water, sewer or storm drain service lines, and planting in the parkway between the sidewalk and street needs a City permit.

Roots back again?

Describe what’s happening and ask for clearing plus a camera check. A local sewer pro can tell you whether to keep clearing or fix the spot where the roots get in.

How do you get rid of tree roots in a sewer line?

Getting roots out is a two-part job: clear the line now, then deal with where they got in.

  • Rooter cutting A machine-driven cable with a cutting head slices through the root mat and reopens the line. It’s fast and usually the first step.
  • Hydro jetting roots High-pressure water cuts roots and flushes the pieces out, and also scrubs the pipe walls clean. Good for heavy root mats and grease.
  • Camera check after Once the line is clear, a camera shows which joints or cracks let the roots in, and how many there are.

Then decide how to stop them coming back:

Option

What it does

Best for

Regular clearing

Cuts the roots back on a schedule

One or two entry points, a tree you want to keep, or a line you plan to fix later

Spot repair

Replaces the bad joint or cracked section

Roots getting in at one place

Pipe lining

A seamless liner seals every joint from the inside

Roots at joint after joint in pipe that still holds its shape

New line

New pipe with tight, sealed joints

A line that is broken, sagging or failing along its length

Will tree roots come back after cutting?

Usually, yes. Cutting removes the roots inside the pipe, but the tree is still there and the opening is still there. Many Greeley homeowners with big trees clear the line on a schedule:

  • Light roots Clearing every 18 to 24 months may be enough, with a camera check now and then.
  • Moderate roots Clearing once a year keeps most lines flowing.
  • Heavy roots If the line backs up more than once a year, it’s time to look at sealing the entry points.

Ask how long the clearing is guaranteed, in writing. A free return if the line backs up again within a set time is a good sign.

Clear or fix? The 10-year cost math

If roots keep coming back, it helps to add up what clearing costs over time and compare it with sealing the entry points once. These are typical 2026 ranges:

Approach

Typical cost

Over 10 years

Clearing once a year

$125 to $600 per visit

About $1,250 to $6,000

Fixing the one joint that lets roots in

$600 to $1,050, one time

Plus an occasional camera check

Lining the whole line

$1,900 to $6,000, one time

Joints sealed, roots kept out

Camera inspection

$175 to $350

Worth doing before you choose

For a line with one or two entry points, a spot repair often pays for itself within a few years of clearing costs. For roots at joint after joint, lining can cost about the same as several years of clearing and ends the cycle. If you love the tree and the line only needs clearing every couple of years, regular clearing can be the sensible choice.

Your real numbers depend on what the camera shows. Our repair cost page has more on prices.

Do root killers, copper sulfate or root barriers work?

  • Foaming root killers Applied after the line is cleared, a foaming root treatment can coat the pipe and slow regrowth for a while. It doesn’t seal the crack, so roots return over time.
  • Copper sulfate Copper sulfate crystals can kill roots they touch, but much of it washes straight past. Ask your sewer pro before using it, and follow the label exactly.
  • Root barriers A buried barrier can steer roots away from a pipe, and works best when a new line or a new tree goes in. It won’t remove roots already inside.

None of these fixes the opening. They can stretch the time between clearings, but sealing the joint or crack is what stops roots for good.

Should you cut down the tree?

Usually not first. Removing a big tree is expensive, the roots already in the pipe stay behind, and other trees can find the same opening. Clear the line and run a camera first. If the pipe is sealed with a spot repair or lining, the tree can usually stay.

If roots come from a neighbor’s tree or a tree in the parkway by the street, the opening in your pipe is still the thing to fix. For a tree in the public right-of-way, ask the City of Greeley Forestry office before any work near it.

Does homeowners insurance cover tree root sewer damage?

Usually not. Standard policies often treat root damage as gradual wear. Colorado’s Division of Insurance describes a separate service line endorsement that covers damaged utility lines on your property, including the sewer pipe.

A water backup endorsement can help with damage inside your home from a backup. Check your policy and call your agent.

Best time to check for roots

  • Before winter, so a backup doesn’t hit during a freeze
  • In late summer or fall, when roots grow toward moist pipes
  • Right after a clearing, to see where they got in
  • Before buying a home with mature trees

Frequently asked questions

Clogs that come back every few months, slow drains all over the house and backups in the lowest drain, especially with large trees nearby. A camera inspection shows the roots inside the pipe.

A sewer pro cuts them out with a rooter cable or hydro jetting, then uses a camera to find where they got in. Sealing that joint or crack with a spot repair or lining keeps them out.

Usually, because the opening in the pipe is still there. Many homeowners clear the line every one to two years, or fix the entry point to stop the cycle.

Cottonwood, poplar, willow, silver maple, ash, elm, boxelder and locust are common culprits near Greeley sewer lines.

Standard policies usually don’t. A service line endorsement may cover the damaged pipe, so check your policy before work starts.

Usually not. Clearing the line and sealing the entry point lets most trees stay.
