4 Signs Tree Roots May Be Reaching Your Sewer Line

Tree roots can enter small sewer-line gaps and grow where moisture is available. These four warning signs are worth checking before a minor drain issue becomes a larger backup.

In this brief: 5 sections 2 min read
    • Notice whether sinks, tubs, and toilets slow together.
    • A single slow drain is often a local clog.
    • Several slow drains can point to a main-line restriction.
    • Listen after toilets flush or tubs drain.
    • Repeated gurgling across rooms is worth noting.
    • It can happen when the main line is partly blocked.
    • Track which fixtures back up and how often.
    • Recurring problems can suggest a deeper obstruction.
    • Roots are one possible cause in older sewer lines.
    • Look for moisture that does not match irrigation.
    • Watch for one patch growing greener than nearby areas.
    • A damaged line can attract root growth around it.
    • Share the symptoms you have noticed and where they occur.
    • Ask for a camera view of the affected sewer line.
    • Use the findings to decide the next repair step.
