How Tree Roots Can Affect Your Foundation and Plumbing

August 1, 2025

Protecting Your Property from Underground Damage

Trees offer countless benefits: shade, privacy, curb appeal, and cleaner air. But when their roots grow unchecked, they can also become a costly threat to your property. For homeowners in the Midwest, root systems from mature or poorly placed trees can lead to serious damage below ground. Foundations can crack. Pipes can rupture. And what starts as a small root intrusion can quickly grow into a major headache.


At Midwest Tree Surgeons, we understand both the value of mature trees and the importance of protecting your home. Here is what you need to know about invasive roots and how to address them before they cause long-term damage.

How Tree Roots Cause Damage

Tree roots naturally grow toward water and nutrients, which often means your underground plumbing and irrigation systems. They also extend in search of oxygen, making cracks or gaps in your foundation a prime target.


Here are the most common issues caused by root intrusion:

  • Cracked or shifting foundations: Roots do not technically “break through” solid concrete, but they can exploit existing weaknesses. Over time, the expanding pressure can worsen foundation cracks, leading to shifting or settling.
  • Broken sewer or water lines: Roots can infiltrate small openings in underground pipes, especially older clay or cast-iron systems. Once inside, they grow and block water flow or cause complete pipe collapse.
  • Damaged driveways and sidewalks: Surface-level root systems can lift concrete slabs, leading to trip hazards and costly repairs.

Warning Signs to Watch For

Many homeowners miss the early indicators of root-related damage. Keep an eye out for these common warning signs:

  • Uneven floors or visible cracks in walls and ceilings
  • Slow drains or frequent plumbing backups
  • Damp or moldy spots in the basement
  • Tree roots visible above ground near the foundation
  • Bulging or cracked sidewalks and driveways


These symptoms may not always point directly to root intrusion, but they are red flags worth investigating, especially if there are large, mature trees near your home.

Tree Types to Watch

Some trees are more aggressive than others. Species with fast-growing or wide-spreading root systems can be particularly problematic. In the Midwest, trees that commonly cause root intrusion issues include:


If you have any of these near your house, driveway, or septic system, it is worth consulting with a certified arborist about potential risks.

What You Can Do

1. Consult a Professional Arborist

Do not guess when it comes to root systems. An arborist can assess the health of your trees, evaluate their placement, and determine whether roots pose a structural risk to your home.


2. Consider Strategic Tree Removal

If a tree’s roots have already infiltrated your foundation or pipes, removal may be the most cost-effective option. At Midwest Tree Surgeons, we remove hazardous trees safely and cleanly, minimizing disruption while preventing future damage.

3. Root Barrier Installation

In cases where you want to preserve a tree but protect your home, root barriers can redirect growth away from foundations and utilities. These are best installed by professionals to ensure they are properly placed and do not harm the tree.


4. Regular Monitoring

Older homes with mature trees should be inspected regularly. Preventative assessments by an arborist can catch problems early and recommend action before damage occurs.

How a Long-Lived Tree Can Become a Valuable Part of a Property’s Identity

October 23, 2026
Some trees become more than landscaping .  They become landmarks . A mature oak near the driveway, an old maple shading the backyard, or a large tree that has stood beside a home for generations can become part of how people recognize and remember a property. That kind of tree has value that is difficult to measure with size alone. It can shape the look of the land, provide shade, frame views, and create a sense of permanence that younger landscaping simply cannot reproduce overnight. That is why preserving a healthy, long-lived tree can be worth serious consideration.

Why Fungal Growth on the Trunk Deserves Attention

October 13, 2026
Mushrooms or other fungal growth on a tree trunk can look harmless, especially if the tree still has a full canopy. But fungal growth can sometimes be a sign that wood inside the tree is beginning to decay. That does not mean every mushroom automatically makes a tree dangerous. It does mean the tree deserves a closer look, particularly when the fungus is growing directly from the trunk, root flare, or a large structural root. For homeowners, recognizing that warning sign early can make it easier to evaluate the tree before a hidden problem becomes more serious.

How to Identify Tree-of-Heaven and Why Professional Removal Matters

October 9, 2026
Tree-of-heaven sounds harmless, but Ailanthus altissima is an aggressive invasive tree that has become established throughout much of the United States, including the Midwest. Originally native to China and Taiwan, tree-of-heaven was introduced to the United States in the late 1700s as an ornamental tree. Its ability to tolerate poor soil, pollution, disturbed ground, and difficult urban conditions helped it spread far beyond cultivated landscapes. Today, it can be found along roadsides, rail corridors, vacant lots, woodland edges, and other disturbed areas throughout the Midwest. Knowing how to recognize it is important because removing it incorrectly can actually make the infestation worse. Look Closely at the Leaves Tree-of-heaven has very large compound leaves made up of numerous individual leaflets. A single leaf can contain roughly 10 to 40 or more leaflets arranged along a central stem. Near the base of each leaflet are distinctive glandular teeth or notches that can help separate tree-of-heaven from similar-looking native species. Crushing the foliage is another useful clue. The leaves can produce a strong, unpleasant odor that has sometimes been compared to rancid or burnt peanut butter.

What Homeowners Should Check Before Severe Winter Weather Arrives

September 29, 2026
Winter can place significant stress on trees, especially when heavy snow, ice, strong winds, and rapid temperature changes arrive together. A tree that appears stable in mild weather may react very differently once branches are loaded with snow or the soil freezes. That is why late fall is a useful time for homeowners to look for warning signs before severe winter weather begins. A careful inspection can help identify weak branches, structural defects, and other concerns that may become more dangerous during a storm.

How Bagworms Can Damage Evergreens

September 23, 2026
Evergreens are often valued because they provide year-round color, screening, and structure in the landscape. When sections of an arborvitae, juniper, spruce, or similar evergreen suddenly begin turning brown or losing foliage, however, bagworms may be responsible. Bagworms are caterpillars that construct protective bags from silk and pieces of the plants they are feeding on. Because those bags blend into surrounding foliage, an infestation can become significant before the insects attract much attention. Understanding how bagworms feed and when they are easiest to control can help protect valuable trees and shrubs from unnecessary damage. The Bags Can Be Easy to Miss Bagworms get their name from the portable cases they build around themselves. As the larvae feed , they add pieces of needles, leaves, and twigs to the outside of the bag. This camouflage can make them difficult to recognize, particularly when populations are still relatively small. The bags may look like small brown cones or pieces of dried vegetation hanging from the branches. Penn State Extension notes that bagworms can become serious pests on arborvitae, juniper, spruce, fir, and other conifers because substantial feeding damage can occur before the infestation becomes obvious.

Why Fall Is a Good Time to Evaluate Tree Structure

September 18, 2026
Fall is an especially useful time to take a closer look at the structure of mature trees . As leaves begin to thin and eventually drop, branches, unions, cracks, cavities, and other structural features become easier to see.  That makes autumn a practical season for identifying problems that may be harder to spot during summer. It also gives homeowners time to address weak limbs or other concerns before winter snow, ice, and wind place additional stress on the canopy.

What Root Flare Can Tell You About Planting Depth

September 10, 2026
A healthy tree should not look like a telephone pole entering the ground. Near the base of the trunk, the tree should widen where the major roots begin to spread outward. This area is known as the root flare, and it can reveal a great deal about whether a tree was planted at the correct depth.  When the root flare is buried under soil, mulch, or landscaping material, the tree may face long-term problems that are easy to miss at first. Looking at the base of the trunk is one of the simplest ways to spot a planting issue before it becomes more serious.

What Sudden Branch Dieback Can Mean

September 2, 2026
A tree can appear healthy overall and still develop a section of dead or dying branches. When branch dieback appears suddenly, especially in one part of the canopy, it can be a sign that something is interfering with the tree’s ability to move water and nutrients where they are needed.  For homeowners, the important question is not simply whether a branch is dead, but why it died. Midwest Tree Surgeons evaluates tree health, structure, pests , disease, and site conditions to help determine what may be causing the change.

Why Topping a Tree Can Create Long-Term Problems

August 25, 2026
When a tree grows too large for its surroundings, removing the upper portion of the canopy may seem like a quick solution. This practice, commonly called tree topping, involves cutting major branches or leaders back to stubs or lateral branches that are too small to assume the terminal role.  Although topping can immediately reduce a tree’s height, it can also create lasting structural and health problems. For homeowners concerned about an oversized or potentially hazardous tree, professional pruning is generally a better approach.

Why Correct Pest Identification Matters Before Treatment

August 18, 2026
When insects begin damaging a tree, the first instinct may be to treat the problem as quickly as possible. But not every insect requires the same response, and some insects that look harmful may not be the actual cause of the decline. Applying the wrong treatment can waste time, money, and potentially put additional stress on the tree.  Midwest Tree Surgeons takes a diagnosis-first approach to tree care. Correct pest identification helps determine whether treatment is needed, which method is appropriate, and whether the real problem may involve disease, environmental stress, or another underlying issue.
