Tree Roots and Residential Plumbing

In this blog post, Rooter Man Plumbing talks about the impact of tree roots on residential plumbing and offers practical solutions to protect your pipes.

How Tree Roots Can Damage Your Residential Plumbing

As we’ve already stated, tree roots tend to grow towards plumbing pipes in search of water and nutrients. Plumbing pipes, especially old ones, can become prime targets for tree roots. Attracted by the water and organic material flowing inside, tree roots find their way through tiny cracks or loose joints. Once inside, they thrive and expand, causing blockages and pipe damage.

Tree roots can spread 2 to 3 times the diameter of the tree’s canopy. This means that a 25-foot tree’s roots may extend 50 to 75 feet or more from the base of the trunk—potentially reaching plumbing lines far from the tree itself. For this reason, it’s important to consider the mature size of trees when planting them near your home and to be aware of the location of your underground plumbing.

Tips to Prevent Tree Roots in Residential Plumbing

Consider Where You Plant Trees

Planning your landscaping with your plumbing in mind is a simple yet powerful way to avoid future problems. Trees may look beautiful lining your driveway or shading your backyard, but if their roots grow too close to your underground pipes, trouble isn’t far behind.

Before planting, take time to locate your home’s sewer and water lines. You can usually request this information through an 811 call service or a local utility map. Once you know where the pipes are, plant trees at a safe distance—at least 10 feet away from sewer lines is a good rule of thumb. And remember, roots don’t stay still. They’ll continue to grow and spread long after that little sapling becomes a towering tree.

Install Physical Root Barriers

You should think of root barriers as a defensive wall for your plumbing system. These underground barriers are designed to redirect or block roots from making their way toward your pipes. If you're planting new trees or shrubs, this is the perfect time to call a local plumbing repair service to install a root barrier between the plants and any underground plumbing lines.

Choose Less Aggressive Tree Species

Not all trees are created equal when it comes to root growth. Some varieties are notorious for sending out long, aggressive roots in search of water. Willows, poplars, maples, and elms—just to name a few—are frequent offenders when it comes to root-related plumbing issues. Instead, opt for tree species with slower, more compact root systems. Some examples include dogwoods, Japanese maples, or Eastern redbuds.
