Can Tree Roots Destroy a Sewer Line?

Written by Steven Shipler, Texas Licensed Master Plumber, Responsible Master Plumber (RMP), MBA.

Yes, tree roots can destroy a sewer line when they enter through cracks, joints, offsets, pipe separations, or damaged sections and continue growing inside the pipe.

Roots are naturally attracted to moisture and nutrients. A small opening in a sewer line can become an entry point. Once roots enter, they can grow thicker, catch waste, restrict flow, and create repeated backups.

Root intrusion usually means the sewer pipe already has an opening where roots can enter.

How Roots Damage Sewer Lines

  • Roots enter through small cracks or loose joints.
  • Roots grow inside the pipe and catch paper, wipes, grease, and debris.
  • Roots can widen openings and worsen pipe separation.
  • Heavy root masses can block the sewer line.
  • Roots can make drain cleaning temporary instead of permanent.

Which Pipes Are Most at Risk?

Older clay pipe, separated joints, damaged cast iron, cracked pipe, and poorly connected repairs are often more vulnerable. PVC can also have root problems if it is broken, offset, or poorly installed.

Can Root Damage Be Found With a Sewer Camera?

Yes. A sewer camera inspection can often show roots inside the pipe, the approximate location of the root intrusion, and whether the roots appear connected to a joint, crack, separation, or pipe defect.

If roots are found, the next step may include cleaning, reinspection, locating, repair planning, or replacement depending on severity.
