Tree roots damage foundations by shifting the surrounding soil. As roots spread in search of water, they displace and dry out the surrounding soil, creating voids that can cause settlement, cracks, and moisture intrusion. However, there are steps you can take to prevent damage caused by tree roots.

This page explains the causes, warning signs, prevention methods, and when to seek a professional for foundation repairs.

How Do Tree Roots Damage a Foundation?

Tree roots damage foundations by expanding through the soil and creating pressure or voids. Root systems often grow as wide as or wider than their canopies. As the supporting soil shifts, your foundation may sink or settle unevenly. This often results in damage, such as foundation cracks and water intrusion through settlement-related openings.

Watch for these warning signs of foundation or drainage problems near large trees or after tree removal:

A crack on a beige wall extends from the corner of a door frame.

Uneven or sloping floors
Stair-step or horizontal cracks in foundation walls
New or widening cracks in drywall, tile, or brick veneer
Doors or windows that stick

Water intrusion or persistent dampness
Excessive settlement around the perimeter
Standing water near the foundation or in the crawl space/basement

If you see these issues, schedule a professional inspection to confirm whether tree roots or another factor is causing the problem.

What Should You Do After Removing a Tree Near Your Foundation?

Removing a tree eliminates the canopy, but roots can remain active for months. Reduce risks by following these steps:

Backfill and compact properly: Fill stump or root cavities with suitable material, compacted in layers.
Improve drainage: Extend downspouts 10 feet, clear gutters, and slope soil away from the home.
Install waterproofing: Use drains, sump pumps, crack sealing, or vapor barriers to limit water intrusion.

Monitor for changes: Check cracks, floors, and sticking doors seasonally.
Address remaining roots carefully: Use trimming or root barriers with help from professionals.

How Can You Prevent Tree Roots from Damaging Your Foundation?

Take these five steps to reduce the risk of tree root damage:

1. Choose Trees Wisely

Select species suited to your soil. Some trees have aggressive root systems that should be avoided.

2. Plant at Safe Distances

Keep large trees at least 20 feet from your home’s perimeter. Aggressive species may require even more distance. If you have existing trees near your foundation, consult with professionals to determine the best course of action for transplanting or removing them from your property. Root barriers may be recommended to redirect roots from sensitive areas.

3. Test Your Foundation Depth

Older homes often have shallower foundations and less robust drainage systems than newer ones, which puts them at a greater risk of foundation damage. A professional inspection can confirm the foundation depth, evaluate the soil, and recommend protective measures tailored to your property.

4. Waterproof Against Hydrostatic Pressure

Invest in home waterproofing measures, such as drainage systems, sump pumps, and vapor barriers, to protect against hydrostatic pressure and water seepage through settlement cracks.

5. Manage Soil Moisture

Consistent watering prevents shrink-swell cycles that stress foundations. However, too much water and improper drainage and grading can cause problems. Balance is key to a healthy yard and foundation.

What Trees Should You Avoid Planting Near Your Foundation?

Certain species have aggressive root systems that make them risky near a home:

American elm
Willow
Hybrid poplar
Silver maple

If you prefer the look of these trees, ask your nursery for alternatives with less invasive roots. Always plant trees at least 20 feet away from your foundation to give them space to grow without disturbing the surrounding soil.

When Should You Call a Professional?

Call a foundation professional if you notice:

New or worsening cracks
Sticking doors or windows
Moisture in the basement or crawl space
Settlement near a recently removed tree

Early intervention is less costly and prevents more extensive structural damage.
