Tree Roots in Your Sewer Line? Here's Exactly What To Do

By Sewer Line Repair Contractors · 2026-09-25 · Perth Amboy, NJ

Tree roots cause more residential sewer backups than every other cause combined. They slip through hairline gaps in pipe joints, grow into thick mats, and eventually choke the line or crack it apart. If your backups return every year or two, roots are the prime suspect.

Step 1: Confirm It's Roots

Don't guess. A sewer camera inspection shows root intrusion unmistakably — white, fibrous masses at the joints. The footage also reveals whether the pipe is intact (good news) or cracked apart (different fix).

Step 2: Cut Them Out Professionally

Mechanical root cutters or high-pressure jetting clear the mass and restore flow, usually within a few hours. Store-bought root killers can't clear an established blockage — they're prevention at best, and harsh on old pipes at worst.

Step 3: Decide — Manage or Eliminate

Cutting buys 12 to 24 months before roots return through the same open joints. For a permanent fix, trenchless lining seals every joint at once — roots lose their entry points for 50 years. Compare the cost of repeated cuttings against one lining and the math usually favors lining.

Should You Remove the Tree?

Almost never necessary. The tree isn't the problem; the vulnerable pipe is. Fix the pipe and the tree can stay right where it is.

Prevention After the Fix

After lining, no prevention is needed — the sealed pipe is the prevention. If you choose managed cutting instead, schedule it every 12 to 18 months and consider foaming root treatments between visits.
