Can Tree Roots Cause Clogged Drains?

Last Revised: 10/3/25

Have you ever noticed your drains slowing down or backing up after a storm? Are you wondering if something as simple as nearby trees (and their roots) might actually be behind your plumbing problems?

At Mattioni, we’ve been helping homeowners in Phoenixville, PA and the surrounding areas for over 75 years – and yes, we’ve seen firsthand how tree roots can quietly wreak havoc on drain lines.

In this article, we’ll explain how tree roots can enter and clog your drains, what signs to look for, and what you can do to fix and prevent the problem. You’ll learn:

• Why tree roots are attracted to sewer lines in the first place
• How to identify a tree root blockage before it turns into a major backup
• The professional solutions available to repair the damage and protect your system

Let’s start with a walk-through of the problem – and how you can stop it.

How Do Tree Roots Get Into Your Plumbing?

Tree roots naturally seek out moisture, and your underground sewer lines – especially older ones – can act like magnets.

Cracks, joints, or weak spots in your sewer and drain lines release small amounts of moisture into the surrounding soil. For trees and shrubs planted nearby, that’s an invitation to grow, as their roots can slip into even the tiniest opening in your pipes. Once inside, they continue to grow and feed off the water and nutrients from your wastewater.

As they expand, the roots usually develop into a net-like structure that can catch debris (like grease, hair, and waste) flowing through the pipes. This gradually builds into a full clog. And unlike a regular blockage, you can’t just flush this one out with a plunger or auger.

What Are the Warning Signs of Tree Root Intrusion?

Tree root clogs often develop slowly, which makes them harder to notice until it’s too late. But there are early signs you can watch for.

You might notice:

• Slower draining from sinks, tubs, or toilets – especially if multiple fixtures are affected
• Gurgling sounds from your drains when water runs elsewhere in your home
• Frequent clogs or backups, even after you’ve cleared them
• Unpleasant odors coming from your drains or basement
• Soggy patches or sinkholes in your yard, especially near trees

These symptoms suggest a blockage deeper in your main drain or sewer line, which is often where root problems occur. Waiting too long can lead to a total backup – causing raw sewage to flood your home or yard, which is hazardous and can be expensive to clean up.

Why Tree Roots Are a Serious Problem

A clog caused by tree roots isn’t just inconvenient – it can turn into a major, costly emergency.

Roots continue growing over time, and as they do, they put pressure on your pipes from the inside. This can lead to:

• Complete pipe collapse, especially in clay or cast-iron systems
• Sewage backups that damage flooring, drywall, and personal belongings
• Widespread plumbing failures, requiring major excavation or pipe replacement

Because the problem starts underground, many homeowners don’t realize how bad it is until major damage occurs. And standard DIY drain treatments won’t solve it – in fact, some chemical drain cleaning products can even make the problem worse.

How Do Plumbers Remove Tree Roots from Pipes?

Thankfully, there are several proven solutions for clearing tree root blockages without tearing up your yard.

A professional plumber will typically start with a video camera inspection to confirm root intrusion and pinpoint the damage. From there, solutions may include:

• Mechanical root cutting using a rotating blade on a drain auger to physically cut and remove the roots
• Hydro jetting, which uses high-pressure water to scour the inside of the pipe clean
• Pipe repair or replacement, such as trenchless pipe lining (cured-in-place) to reinforce the damaged area without excavation

The right solution depends on how severe the damage is. But the key is acting early – before the blockage turns into a break in the pipe.

How to Prevent Tree Root Clogs in the Future

Once the roots are cleared, the next step is prevention – so the problem doesn’t come back in a year or two.

Here’s what we recommend:

• Schedule regular drain inspections, especially if you have older pipes or large trees near your home
• Avoid planting trees or shrubs too close to your sewer line (ask your plumber or use public utility maps to locate it)
• Use root barrier systems if you’re doing landscaping near buried lines
• Opt for trenchless pipe liners when possible, if your pipes are already compromised

A proactive approach can save you thousands in repair costs and protect your home from sudden sewage backups.
