How Roots Damage Your Foundations

Phoenix, United States – July 15, 2026 / Elite Tree Service /

A tree in the backyard can look harmless, yet its roots may still influence the soil conditions near a home. Some Phoenix homeowners may not notice a concern until doors stick or cracks appear along a wall. Understanding the answer to “Can tree roots damage foundations?” is the first step toward catching an issue before it becomes difficult to manage.

In this release, Elite Tree Service outlines how root behavior and soil conditions interact, which species tend to cause the most concerns locally, and which changes around the home deserve a closer look.

Can Tree Roots Damage Foundations?

Tree roots rarely crack concrete through sheer force. The more common issue involves what happens to the soil underneath a home. In parts of Phoenix with expansive clay soil, roots can draw moisture from the ground as they grow, and when that moisture disappears, the clay contracts.

Once the ground no longer supports the structure evenly, the foundation can gradually move. Soil movement tends to worsen during extended dry stretches, which makes seasonal timing a factor worth watching.

Higher-Risk Trees Common to Phoenix Yards

Phoenix homeowners planning new landscaping or reviewing existing trees may want to keep an eye on the following trees:

Mesquite: This species often develops extensive roots as it searches for moisture in dry soil.
Mulberry: These are known for large root systems that can extend toward nearby water sources when space is tight.
Cottonwood: This fast-growing tree has roots that tend to spread aggressively, particularly near water.
Palo verde: This species is desert-adapted overall, but its roots can still reach toward underground utilities if planted too close to a home.

Choosing the right planting distance can help reduce the chance of roots reaching foundations or underground lines.

Warning Signs Worth Taking Seriously

Watch for these changes around the home and nearby soil:

Cracks forming along the foundation or exterior walls
Doors and windows that suddenly stick or stop closing evenly
Floors that feel noticeably sloped in certain rooms
Roots that are becoming visible above the soil surface near the home

Recognizing the signs that it’s time to call a tree service can help homeowners act before a manageable issue turns costly.

Watering Habits and Root Direction

Shallow, frequent watering keeps roots close to the surface, since that is where moisture stays most consistent. Shallow root growth may increase the chance of roots spreading near hardscapes or structures. Switching to deeper, less frequent watering encourages roots to grow downward instead of outward.

What Comes Next After a Problem Is Suspected

Elite Tree Service can assess the tree’s condition and help determine whether root-related concerns need closer review before any major decision is made. A structural foundation inspection helps determine how serious the movement actually is. From there, a certified arborist can determine whether a root barrier installation or selective pruning may be appropriate near the property.
