Trees with Aggressive Root Systems That Can Invade Sewer Lines

Trees contribute greatly to a property’s aesthetic and environmental value, but certain species come with a significant caveat—their roots can spread far and wide in search of water sources, often causing damage to nearby underground infrastructure such as sewer lines. For homeowners, the consequences of these root invasions can range from minor inconveniences to major plumbing repair costs. Recognizing these species (that you may want to think twice about planting in your yard) can save you from headaches down the line.

 

Willow Trees

Willow trees are often found near bodies of water, as they require a lot of moisture to thrive. When planted in residential areas, they can pose a threat to sewer lines and underground pipes (their roots can spread up to three times the width of their canopy). These strong, fast-growing roots can easily infiltrate small cracks, causing blockages and potential leaks. Don’t be fooled by their graceful appearance, as willow trees can cause major trouble for your plumbing in Ventnor City, NJ if not properly managed.

 

Poplar Trees

Poplar trees have extensive root networks that grow aggressively both horizontally and vertically. These roots can reach deep underground, wrapping around pipes and exploiting weak points to access the water inside. Poplar roots are also fibrous, meaning once they enter a sewer line, they quickly form a dense mat that collects debris and accelerates clog formation. These traits make poplars particularly dangerous for older sewer systems with clay or cast-iron pipes.

 

Oak Trees

Oaks are slow-growing trees, but their roots are incredibly strong and persistent. They can gradually apply pressure to sewer pipes, causing hairline fractures that worsen over time. Oaks also produce deep taproots in addition to lateral roots, giving them multiple pathways to infiltrate plumbing systems. Any experienced plumber would agree that while oaks may not cause immediate issues like faster-growing species, their long lifespan and powerful root systems can cause hidden damage that goes unnoticed until a major plumbing failure occurs.

 

Silver Maple Trees

Silver maples are prized for their fast growth and shade, but their roots are known to cause serious infrastructure damage. The roots grow close to the surface, which makes them more likely to push through loose pipe joints or shallow sewer lines. In addition to pipe blockages that would necessitate plumbing services to resolve, silver maple roots can also lift sidewalks and damage home foundations, making them a risky choice for small yards or properties with aging plumbing systems.
