Can Tree Roots Cause Concrete to Settle or Crack?

Trees are one of the best features of many Spokane neighborhoods.

They provide shade, improve curb appeal, and add long-term value to a property.

However, homeowners often wonder whether nearby trees could also contribute to uneven sidewalks, cracked driveways, or settling patios.

The answer isn't always straightforward.

While tree roots can influence concrete, they're often only one part of a much larger picture that includes soil conditions, drainage, moisture levels, and seasonal weather. If you're curious about what causes concrete to settle in the first place, read our guide to Why Concrete Sinks in Spokane.

How Tree Roots Affect Concrete

Tree roots naturally grow toward available moisture and nutrients.

As they grow, they may interact with nearby concrete in different ways.

Depending on the location, homeowners may notice:

• Sidewalk panels lifting
• Surface cracking
• Concrete becoming uneven
• Separation between slabs

Not every tree causes these issues, and not every uneven slab is the result of roots.

Moisture Can Be Just as Important

Many mature trees absorb large amounts of water from surrounding soil.

In Spokane, changing moisture conditions throughout the year may influence how soil expands, contracts, or settles.

This means a tree can affect concrete indirectly by changing soil moisture—not simply by pushing upward with its roots. For more on how water interacts with concrete, see our article on Why Water Is Pooling on Your Driveway.

Areas Most Commonly Affected

Tree-related movement is more often seen around:

• Sidewalks
• Walkways
• Patios
• Landscape borders
• Garden paths

Driveways may also be affected when mature trees are located nearby. If you're noticing changes along a walkway or outdoor living area, learn more about sidewalk leveling and patio leveling options.

Spokane's Mature Neighborhoods

Many established Spokane neighborhoods feature large shade trees that have been growing for decades.

As these trees mature, their root systems naturally expand.

Regular inspections around sidewalks, patios, and driveways can help homeowners recognize gradual changes over time. Our Spring Concrete Inspection Checklist offers a simple seasonal routine.

Warning Signs to Watch For

Look for:

• Concrete beginning to lift
• New cracks near tree roots
• Sidewalk sections becoming uneven
• Separation between slabs
• Changes occurring near mature trees

Taking photographs each spring can make gradual movement easier to identify. If you notice new cracking, our guide on When Should You Be Concerned About Cracks in Concrete? can help you interpret what you're seeing.

Should You Remove the Tree?

Removing a tree isn't always the best—or necessary—solution.

Trees provide many environmental and aesthetic benefits.

If you suspect a tree is affecting nearby concrete, consider learning more about the condition before making significant landscaping decisions.

Every property is unique, and several factors may contribute to concrete movement.

Frequently Asked Questions

Do tree roots always crack concrete?

No. Many trees grow near concrete for decades without causing noticeable problems.

Can roots make sidewalks uneven?

They can contribute in some situations, especially as trees mature.

Should I cut exposed roots?

Removing roots may affect the health or stability of a tree. If root work is being considered, consult an appropriate tree care professional before making changes.

Does Spokane's climate play a role?

Yes. Seasonal moisture changes, freeze-thaw cycles, and changing soil conditions all influence how concrete performs over time.

Final Thoughts

Tree roots are only one possible contributor to concrete movement.

By understanding how trees, soil, drainage, and Spokane's seasonal weather work together, homeowners can better evaluate changes around their property and make informed maintenance decisions.
