Tree Roots in Sewer Lines: Warning Signs and Solutions

By the Scarborough Drain team ·

Mature trees are part of what makes many neighbourhoods attractive, but their roots can find their way into older drain pipes.

How roots get in

Roots grow toward moisture. Small cracks or loose joints in a drain pipe release water vapour that attracts fine roots, which then grow inside the pipe.

Warning signs

  • Gradually worsening drainage throughout the home
  • Main drain backups that recur every few months
  • Gurgling toilets and floor drains
  • Roots retrieved during drain cleaning

Clearing the roots

Root clearing restores flow. Because the opening remains, roots often regrow, so periodic maintenance may be needed.

Longer-term options

A camera inspection shows where roots are entering and how damaged the pipe is. Depending on what's found, repairing the affected section may provide a longer-lasting solution.
