Absolutely. Tree roots can completely destroy sewer lines over time, especially older clay pipes with loose joints. Roots start small, finding tiny cracks or gaps, then grow larger and eventually break the pipe apart.
In Sutter’s soil conditions, we regularly find roots that have created massive blockages or completely crushed pipe sections. Oak trees, in particular, have extensive root systems that can reach sewer lines 50+ feet away.
Once roots establish themselves in your sewer line, they’ll keep growing back unless you address the structural problem that let them in. Simple root cutting is temporary – you need to seal or replace the damaged pipe section for a permanent solution.
