If tree roots are in your sewer line, a plumber has to cut them out, and then the entry point has to be sealed. Cutting alone is temporary. The roots got in through a crack or a loose joint, and they will come back until that opening is repaired. A camera inspection shows where the roots are, how much pipe damage there is, and whether you need a cleaning, a liner or a replacement.
This guide covers the warning signs, what you can safely do yourself, how professionals clear roots, what repairs cost, and who pays. We are a plumbing company in Rogers, AR, so we also note where local rules matter.
TL;DR
- Slow drains, gurgling, repeated clogs and wet or lush patches in the yard are the classic signs of roots in a sewer line.
- Roots usually do not break a sound pipe. They enter through existing cracks and loose joints, according to N.C. Cooperative Extension.
- Cutting or jetting clears the line, but roots typically return within 1 to 3 years unless the entry point is sealed with a liner or replacement.
- Standard homeowners policies generally exclude root damage. Optional service line coverage may help.
- A camera inspection is the only reliable way to see what is in the pipe before you choose a repair.

Signs of tree roots in a sewer line
Root problems build slowly. The early signs are easy to mistake for a simple clog:
- Slow drains in more than one fixture. A single slow sink is usually a local clog. Slow tubs, toilets and floor drains together point to the main line.
- Gurgling. Air pushed back through traps when water is flushed or drained.
- Repeat clogs. You clear the line and it backs up again within weeks or months.
- Sewage odor inside the house or in the yard near the line.
- Wet spots, sinkholes or unusually green strips of lawn along the path of the pipe. A leaking sewer feeds the grass above it.
- Backups in the lowest drain. A basement floor drain or first-floor tub is where sewage shows up first.
If several of these happen at once, treat it as a main line issue. Our guide on which fixtures to check when a drain keeps backing up helps you tell a local clog from a main line problem. If sewage is coming up inside the house, stop using water and call for emergency plumbing repair.
In Arkansas homes with a septic system instead of a city sewer, the same symptoms can come from the septic line or tank. Our page on septic backup signs covers that case.
Why roots get into sewer pipes
A common belief is that roots punch through solid pipe. They mostly do not. Tree roots search the soil for moisture and nutrients. When a pipe has a weakness, roots will find it and exploit it. A tiny root enters a hairline crack or a loose joint, then thickens as it feeds on the water and waste inside.
The city of Lakewood, CA puts it plainly: roots do not usually cause the original cracks, but they are drawn to the water that leaks out. That matches what we see on camera.
What this means for you:
- Older materials are the usual entry points. Clay tile and cast iron have many joints and tend to crack or corrode with age.
- PVC resists roots well, but poor installation can leave unsealed joints or open ends that give roots a way in.
- Tree location is a weaker predictor than pipe condition. Extension guidance notes that roots can travel far for moisture, so planting a tree farther away does not guarantee protection if the pipe is already compromised.
- Once roots are in, they trap debris. Grease and paper catch on the root mass, and the blockage grows.
Confirm the problem with a camera inspection
Guessing is expensive. Before cutting, lining or digging, have a technician run a camera through the line. A plumbing video camera inspection shows:
- Where the roots enter, and how many entry points there are
- Whether the pipe is cracked, offset, bellied or collapsed
- The pipe material and approximate condition
- The depth and distance to the problem, so a repair can be planned and priced
This also matters if you are buying a home. A camera inspection of the sewer line before closing can reveal a root problem the seller never mentioned, and gives you leverage on price or repairs.
How roots are removed
There are four main approaches. They solve different problems.
| Method | What it does | How long it lasts | Best for |
|---|---|---|---|
| Mechanical cutting (auger or cable) | Cuts roots out of the pipe | Short term; roots regrow | Clearing a blocked line quickly |
| Hydro jetting | High-pressure water scours roots, grease and debris from pipe walls | Short term unless the entry point is repaired | Heavy buildup, thorough cleaning |
| Foaming root control | Chemical foam coats the pipe to slow regrowth | Extends time between cleanings; does not fix defects | Maintenance after cutting |
| Lining or replacement | Seals or replaces the damaged pipe | Long term | Permanent fix |
Cutting and hydro jetting
Cutting opens the line. Hydro jetting does more of the cleanup, because the water washes away root fragments, grease and scale that a cutter leaves behind. Neither method touches the crack the roots came through. A source summarized in our research puts regrowth at roughly one to three years, depending on the line, the tree and the soil. For drain cleaning and repair, that is the honest expectation: it is maintenance, not a cure.
Chemical root killers
Readers often ask about the best chemical. A few cautions:
- Professional-grade foaming products are EPA-registered pesticides applied as foam so they coat the whole pipe interior. The Idaho State Department of Agriculture's sewer line chemical root control manual covers how these are used.
- Some are restricted-use. One EPA-registered foaming product label is marked as a restricted use pesticide, sold only to certified applicators or people under their direct supervision.
- Copper-based products can be restricted where wastewater treatment relies on microbes, so check local rules before using any chemical, and never mix products.
- Foam slows regrowth. It does not repair cracks and does not remove a thick root mass.
If you have a septic tank, ask a plumber before putting any root killer down the drain. Chemicals can harm the bacteria your system needs.
Trenchless lining and pipe replacement
If the camera shows roots entering at joints or cracks, sealing the pipe is the lasting answer. Trenchless plumbing repair lets us line or replace a pipe with minimal digging, so your driveway, patio and landscaping stay mostly intact. If the pipe has collapsed or has a serious offset or belly, a lining may not be an option and a section needs to be replaced with a traditional dig. The camera tells us which applies. Our water and sewer line repair page lists what we handle.
What tree roots in a sewer line cost to fix
Prices depend on pipe length, depth, material, access and method. We do not publish fixed prices, because a camera has to show the condition first. These national figures give you a frame of reference:
- Sewer line repair and replacement typically runs from $1,500 to $10,000 nationwide as of 2026, with an average around $4,500.
- The same source reports spot repairs often start around $500, and that minor root intrusions can be cut and the line relined for roughly $1,500 to $3,500.
- Severe damage, where the pipe has collapsed or offset, requires replacement and costs more. Full trenchless lining or replacement can climb toward $15,000 on long or complex runs.
For a closer look at replacement, see our breakdown of sewer line replacement cost for a 50-foot run.
A worked example shows why the sequence matters. Say you pay to have roots cut every 18 months. Each visit is a smaller bill, but you never stop paying, and the pipe keeps deteriorating. Two or three cleanings can approach the price of a liner that ends the cycle. If the pipe is in decent shape, repeat cleaning plus foaming may be the right economic choice. If it is cracked at several joints, repair is.
Who pays: insurance and responsibility
Does homeowners insurance cover roots?
Usually not by default. Standard homeowners policies generally exclude tree root damage, treating it as maintenance or wear and tear. Coverage tends to apply only to sudden, accidental events on your property, such as a burst.
Many insurers offer optional service line or buried utility coverage. One insurer's buried utility lines overview says the line must be on the insured premises and serve the residence. Typical add-ons offer up to about $10,000 with a deductible near $500, though terms vary by carrier. Read your policy for the words "service line," "buried utility" and "tree roots," and call your agent before work begins. Take photos and keep the camera footage, since insurers often ask for documentation.
The sewer lateral and the property line
The lateral is the pipe from your house to the public main. In most cases the homeowner is responsible for the private lateral, regardless of whose tree is causing the problem. Responsibility can extend further, though. A sewer lateral responsibility guide notes that some utilities or city codes assign the owner part of the line under streets or sidewalks, while others take over at the property line or the main.
In Rogers, the city sewer is run by Rogers Water Utilities. Before a repair that crosses the property line or a utility easement, ask the utility where private responsibility ends. Properties outside the city may be on septic or on a different utility altogether. If a neighbor's tree is the source, you may have a claim against them in some situations, but expect the pipe repair itself to be yours to arrange first. For legal questions, talk to an attorney licensed in Arkansas.
How we approach roots in a sewer line
We see the same pattern on most root calls. A homeowner has cleared the line two or three times, and each time it comes back. The cleaning was never the problem. The unrepaired pipe was.
Our view:
- Look before you cut. We want a camera on the line first, so the repair matches the damage.
- Clear the line properly. If water is backing up, we clear it first. Hydro jetting leaves cleaner pipe walls, which also makes the camera view clearer.
- Fix the entry point when the pipe calls for it. If roots return on a schedule, cleaning is a recurring cost. Lining or replacing the damaged section ends it.
- Choose the least disruptive repair that lasts. Trenchless methods suit many lines. When a pipe has collapsed, we say so and explain why digging is needed.
- Quote before work. Pricing should be clear before we start, with the findings shown to you.
We do not recommend cutting down a healthy tree as a first move. Removal may help in some cases, but a stump and old roots still draw moisture, and an unrepaired pipe still leaks. Fix the pipe first, then decide about the tree.

Keep roots out after the repair
No prevention step replaces a sound pipe, but these help:
- Repair or reline cracked, offset or loose-jointed pipe. This is the main defense.
- Schedule periodic camera checks if you have an older clay or cast-iron lateral or a mature tree nearby.
- Use professional foaming treatments only if recommended and permitted locally. They are maintenance, not repair.
- Water trees deeply and away from the pipe. Roots chase the easiest water. A guide to deep root watering for homeowners explains how deeper, less frequent watering encourages roots down rather than toward a leaky line.
- Pick the right tree and place. Fast-growing, thirsty species such as willows and maples do the most harm near lines. Check where your lateral runs before planting.
- Get help with big removals. If a tree near the line has to come out, a land clearing and tree removal contractor can handle the debris and grading. Tell them where the sewer line runs so heavy equipment does not damage it. That company works in South Carolina, so look for a similar crew near Rogers.
- Do not flush grease or wipes. Roots trap debris, and debris makes any root problem worse.

FAQ
How do you get rid of tree roots in a sewer line?
A plumber cuts the roots with an auger or clears them with hydro jetting, then runs a camera to find where they came in. To keep them out, the cracked or loose section has to be sealed with a liner or replaced. Without that step, roots usually regrow within one to three years.
How much does it cost to get tree roots out of a sewer line?
Cutting or jetting is the lower-cost part, and the price depends on line length and access. Repair after clearing is the larger cost. National figures put sewer repair and replacement at about $1,500 to $10,000, with a camera inspection needed to price your line.
Does homeowners insurance cover tree roots in a sewer line?
Standard policies generally exclude it as maintenance or wear and tear. Optional service line or buried utility coverage may pay, often up to around $10,000 with a deductible. Check your policy and call your agent before work starts.
What is the best chemical for killing tree roots in a sewer line?
Professionals use EPA-registered foaming products that coat the pipe wall. Some are restricted-use and limited to certified applicators, and some products can harm septic or treatment-plant bacteria. Foam slows regrowth but does not repair the pipe, so ask a plumber before using one.
