Tree disputes between neighbours are more common than many Calgary homeowners realize. While trees provide shade, privacy, curb appeal, and environmental benefits, problems can arise when roots extend beyond property lines and begin affecting lawns, gardens, sidewalks, driveways, retaining walls, or even foundations.
One of the most common questions homeowners ask is whether they are legally allowed to cut roots from a neighbour's tree when those roots cross onto their property.
The short answer is yes, but there are important considerations before you start digging or cutting. Understanding your rights, the potential risks to the tree, and the long term consequences can help you avoid costly mistakes and neighbour disputes.
At Evergreen LTD, we regularly help Calgary homeowners assess tree root issues and determine the safest course of action for both the property owner and the tree.
Understanding Property Rights and Tree Roots
In Canada, property owners generally have the right to address roots and branches that extend onto their property from a neighbouring tree.
This means that if roots are crossing the property line and affecting your landscaping or outdoor space, you may be permitted to remove the portion that exists on your side of the property.
However, just because root cutting may be legally permitted does not necessarily mean it is the best solution.
Before taking any action, it's important to understand how tree roots function and what impact removing them could have on the health and stability of the tree.
If you're dealing with an encroaching root system, Evergreen LTD can assess the situation and help you determine the safest approach.
Why Cutting Tree Roots Can Be Risky
Many homeowners assume tree roots are similar to branches and can simply be trimmed back without consequences. In reality, roots play a critical role in a tree's survival.
Roots anchor the tree, absorb water and nutrients, and help maintain overall health and stability. Removing significant roots can create problems that may not become apparent for months or even years.
Potential consequences of excessive root cutting can include:
Reduced tree health
Increased susceptibility to disease
Declining canopy growth
Structural instability
Increased risk of storm damage
Premature tree death
In Calgary, where strong winds and unpredictable weather are common, root damage can significantly affect a tree's ability to remain stable during severe conditions.
What If the Tree Is on City Property?
One of the first steps is determining who owns the tree.
If the tree is growing on private property, different rules apply than if it is located on City-owned land. Calgary's regulations provide protections for public trees, and unauthorized damage to municipal trees may lead to penalties.
Many homeowners are surprised to discover that a tree they assumed belonged to a neighbour is actually part of a municipal boulevard or public green space.
Before any root cutting takes place, it is important to verify ownership and ensure you are not accidentally damaging a protected tree.
Could You Be Liable for Damaging the Tree?
This is where many homeowners encounter unexpected challenges.
While you may have the right to address roots on your property, significant damage caused by improper root cutting could potentially create liability issues. If extensive root removal contributes to the decline, instability, or death of the tree, disputes between neighbours can quickly arise.
Every situation is unique. The size of the roots, the species of tree, the extent of the pruning, and the condition of the tree all play a role in determining potential outcomes. An assessment from Evergreen LTD can help determine the safest approach before any roots are removed.
Taking a cautious and informed approach can help protect both your property and your relationship with your neighbour.
Consider Talking to Your Neighbour First
Although legal rights are important, practical communication is often the best starting point.
Many tree root issues can be resolved through a simple conversation before they become larger conflicts. Your neighbour may not even be aware that the roots are causing problems on your property.
Working together often creates opportunities for better solutions, including:
Professional root assessments
Root barrier installation
Targeted root pruning
Tree maintenance plans
Shared management costs
A cooperative approach can save time, money, and unnecessary tension between neighbours.
Alternatives to Cutting Tree Roots
In many situations, root removal is not the only option.
Depending on the nature of the problem, alternatives may provide a better long term outcome while preserving the health of the tree.
Potential solutions may include:
Root Barriers
Root barriers can redirect future root growth away from sidewalks, driveways, gardens, and structures.
Professional Root Pruning
Selective root pruning performed by a qualified arborist can minimize damage while addressing specific concerns.
Tree Health Management
Sometimes root problems are linked to broader tree health issues that can be addressed through proper maintenance and care.
Landscape Modifications
Adjustments to hardscaping or landscape design may help accommodate existing roots without harming the tree.
When Should You Call an Arborist?
If roots are affecting your property, the best time to seek professional advice is before any cutting occurs.
A qualified arborist can identify critical structural roots, assess tree health, evaluate risks, and recommend solutions that balance property concerns with long term tree preservation.
