3 Ways Tree Roots Damage Your Sewer Line

November 11, 2025

As homeowners, we often admire the beauty and shade that trees provide to our properties. However, lurking beneath the surface, tree roots might be causing unanticipated harm to your sewer lines. The interaction of tree roots with sewer infrastructure can lead to significant problems, including blockages and structural damage that can be fixed with a sewer service or sewer cleaning service. According to IBISWorld, the septic, drain, and sewer cleaning services market size in the U.S. was $7.8 billion in 2024. Understanding how tree roots damage sewer lines can help you take preventive measures with a professional sewer service.


1. Roots Are Naturally Drawn to Sewer Lines

The first way tree roots damage your sewer line is by naturally seeking out the nutrient-rich environment that sewer lines provide. Trees are instinctively drawn to sources of water and nutrients, and sewer pipes often house moisture and organic material that roots find appealing. Over time, these roots penetrate through small cracks or joints in the pipes, leading to blockages and significant plumbing issues. Unfortunately, even a small intrusion can cause major problems within the system.


2. Expanding Roots Create Structural Damage

As tree roots expand, they exert pressure on sewer lines, which can lead to cracks, breaks, or misalignment. The persistent growth of roots within the pipes can cause structural damage that is costly and time-consuming to repair. Awareness of the connection between expanding roots and structural damage is crucial for homeowners seeking to mitigate plumbing repair expenses by addressing root growth early.


3. Roots Create Blockages and Clogs

Lastly, tree roots are notorious for causing severe blockages and clogs in sewer lines. Once inside, roots can continue to grow and multiply, leading to almost impenetrable obstructions. These obstructions not only cause backups and overflows but can also lead to unpleasant sewage odors around your property. Through regular inspections and prompt action, homeowners can manage early root intrusions before they develop into extensive blockages requiring professional intervention.


Understanding the different ways in which tree roots can damage your sewer line is essential for maintaining a healthy plumbing system. By recognizing the intended natural behavior of roots targeting rich resources, the inevitable structural damage, and the formation of blockages, you can better prepare for and prevent these costly issues.
