01 · What it is

What is tree root intrusion (sewer)?

Tree roots grow into sewer pipes through joints, cracks, and faulty connections, drawn by the moisture and nutrients inside the line. Once inside, roots form a fibrous mass that catches debris and causes partial-to-full blockages.

02 · Why it matters

Why inspectors flag this

Untreated root intrusion progresses to full sewer backups inside the home, sewer-line replacement (often $5,000–$15,000), and yard excavation. It is one of the most common findings during pre-purchase sewer scope inspections of homes 30+ years old.

03 · Example report wording

How professional inspectors report it

Liability-safe sample comment

Heavy root mass observed at 22 feet from foundation cleanout. Estimated 60% cross-sectional blockage of the sewer lateral. Recommend hydro-jet root removal and chemical root treatment by a licensed plumbing contractor. Consider epoxy lining or pipe replacement if intrusion recurs.
