Why Are My Tree Roots Coming Out of the Ground? What Calgary Homeowners Should Know

Seeing tree roots rise above the surface of your lawn can be concerning. They can make mowing more difficult, create tripping hazards, and leave many homeowners wondering if their tree is in trouble.
The good news is that exposed roots are often a natural part of how trees grow. However, they can also be a sign that environmental conditions around your tree have changed. Understanding why roots become exposed is the first step toward protecting your tree's health and avoiding costly mistakes.
If you're unsure whether your tree's exposed roots are normal or a sign of a larger issue, Evergreen LTD's ISA Certified Arborists can assess your tree and recommend the best course of action.
Surface Roots Are Often Completely Natural
Many people assume tree roots should grow deep underground, but that's rarely how healthy trees develop.
Most of a tree's root system is found within the upper layer of soil, where oxygen, water, and nutrients are most readily available. As a tree matures, its large structural roots naturally spread outward, sometimes becoming visible above the surface.
This is especially common with mature trees and certain species that naturally develop shallow root systems.
In many cases, exposed roots are simply a sign that your tree has grown successfully over many years rather than an indication that something is wrong.
Soil Erosion Can Expose Healthy Roots
Sometimes the roots haven't moved upward at all. Instead, the soil around them has gradually washed away.
Heavy rainfall, snowmelt, poor drainage, and Calgary's freeze-thaw cycles can slowly remove topsoil over time, leaving roots exposed that were once buried beneath the surface.
Properties with slopes or areas where water frequently collects are particularly susceptible to erosion.
As more roots become exposed, they lose some protection from temperature changes, lawn equipment, and foot traffic, making proper management increasingly important.
If you've noticed exposed roots becoming more visible each year, Evergreen LTD can determine whether erosion is affecting your tree and recommend practical solutions to help protect both your landscape and the tree itself.
Compacted Soil Forces Roots Toward the Surface
Urban trees face challenges that trees growing naturally in forests rarely experience.
Years of foot traffic, parked vehicles, construction activity, or heavy landscaping equipment can compress the soil around a tree. When soil becomes compacted, oxygen and water struggle to move through it, making it difficult for roots to grow deeper.
Instead, roots spread closer to the surface where growing conditions are more favourable.
Compacted soil is one of the most common stresses affecting trees in urban environments and often contributes to slower growth and declining health over time.
Calgary's Soil Can Limit Root Growth
Not every property offers ideal growing conditions.
Many areas throughout Calgary contain shallow topsoil over dense clay, gravel, or other hard soil layers. When roots encounter these barriers, they often have little choice but to spread outward near the surface.
Even healthy trees can develop visible roots in these conditions because the soil simply doesn't allow them to grow deeper.
What Should You Do About Exposed Tree Roots?
One of the biggest mistakes homeowners make is trying to hide exposed roots.
Adding a thick layer of soil over existing roots may seem like a simple fix, but it can reduce the oxygen reaching the root system and place additional stress on the tree.
Cutting large surface roots can be even more damaging. Structural roots help anchor the tree and transport water and nutrients throughout the canopy. Removing them may weaken the tree's stability while creating entry points for insects and decay.
Instead, the safest approach often includes:
Applying a layer of organic mulch around the tree while keeping it away from the trunk.
Protecting the root zone from lawn equipment and excessive foot traffic.
Addressing drainage issues that contribute to soil erosion.
Improving compacted soil using professional arboricultural techniques when necessary.
How Evergreen LTD Can Help
Exposed roots don't always require treatment, but they should be properly evaluated before any changes are made.
At Evergreen LTD, our ISA Certified Arborists assess the entire growing environment, not simply the roots you can see. We look at soil conditions, drainage, tree health, site history, and potential safety concerns before recommending a solution.
Depending on your tree's condition, we may recommend:
Tree health assessments.
Soil evaluations.
Soil aeration to reduce compaction.
Organic mulching.
Erosion management strategies.
Long-term monitoring and maintenance.
Our goal is to protect the health of your tree while helping you avoid unnecessary work that could cause permanent damage.
Protect Your Tree's Roots Before Small Problems Become Bigger Ones
Surface roots are often a normal part of a healthy tree, but they can also reveal underlying issues such as erosion, compacted soil, or challenging growing conditions. Knowing the difference is essential before making changes to your landscape.
If you've noticed tree roots emerging above the ground, Evergreen LTD can provide a professional assessment and explain exactly what's happening beneath the surface.
