Trees bring beauty and shade to our homes and neighborhoods, but when they start to show signs of trouble, they can turn into serious hazards. A weak or dying tree isn’t just an eyesore—it can put your home, car, and even your family at risk.
If you’ve ever wondered, “Is that tree in my yard safe?” or “Should I be worried about that leaning tree near the sidewalk?”—this guide is for you.
For homeowners in the Triangle, tree care isn’t just about aesthetics—it’s about safety. Whether you’re a homeowner protecting your yard or a municipal manager ensuring public spaces remain hazard-free, knowing the warning signs of a dangerous tree can prevent costly damage and injuries.
Why Identifying Tree Hazards Early Matters
At a glance, most trees seem sturdy. But just like people, trees can get sick, suffer damage, and become weaker over time. The problem is, the signs of a hazardous tree aren’t always obvious until it’s too late.
Common risks of hazardous trees include:
- Storm damage – High winds and heavy rains can break weak limbs or uproot unstable trees.
- Rot and decay – Internal damage may not be visible but can make a tree structurally weak.
- Overhanging limbs – Branches extending over homes, sidewalks, or power lines increase the chance of damage or injury.
A tree that seems fine today could become a serious hazard tomorrow. That’s why regular tree assessments are essential—whether you’re a homeowner protecting your family or a parks manager ensuring public spaces are safe.

7 Warning Signs of a Dangerous Tree
If you notice any of these warning signs, your tree may be at risk of falling.
Cracks and Splits in the Trunk
- Large, visible cracks or deep splits can indicate severe structural weakness.
- Trees with multiple cracks are more likely to break, especially during storms.
Leaning or Unstable Posture
- A tree that wasn’t always leaning but suddenly starts tilting could have root damage or shifting soil.
- A severe lean—especially after a storm—is a major red flag.
Dead or Hanging Branches
- Dead branches are brittle and easily snap, which makes them dangerous in high winds.
- Look for branches that don’t produce leaves during the growing season.
Root Damage or Weakness
- Exposed, damaged, or decaying roots can make a tree unstable.
- Trees near recent construction, sidewalks, or driveways may have suffered root disturbances that weaken their ability to stay upright.
Fungal Growth at the Base
- Mushrooms or fungi growing around the tree’s base often indicate internal rot and decay.
- Even if the tree looks fine on the outside, it may be hollow inside.
Hollow or Cavities in the Trunk
- Not all hollow trees are dangerous, but large cavities can weaken structural integrity.
- A tree with a hollow trunk should be assessed by a Certified Arborist.
Bark Peeling or Missing in Large Sections
- While some trees naturally shed bark, widespread peeling can signal disease, decay, or structural weakness.
- If bark loss is accompanied by cracks or leaning, the tree could be a hazard.
What to Do If You Suspect a Tree Is Dangerous
So, you’ve spotted a warning sign—what now? Here’s what to do next:
- Conduct a visual inspection – Walk around the tree and look for any of the warning signs mentioned above.
- Avoid standing under unstable trees – If you notice cracks, leaning, or dead branches, stay clear.
- Call a Certified Arborist for an assessment – A trained arborist can evaluate tree health, diagnose disease or structural issues, and determine whether a tree needs to be removed or saved.
- Act quickly – Waiting too long can lead to costly damage, liability issues, or safety hazards for your family, neighbors, or community.

Tree Removal vs. Tree Maintenance: When to Take Action
Not all dangerous trees need to be removed. Some can be saved with professional care.
When removal is necessary:
- The tree is completely dead or rotting from the inside.
- The roots are heavily damaged, making the tree unstable.
- The tree is leaning dangerously and at risk of falling.
See more information about tree removal on our website.
When trimming or pruning is enough:
- A few dead branches pose a risk, but the tree is otherwise healthy.
- The tree is near power lines but not structurally compromised.
- The roots are causing minor issues, but the tree can be stabilized.
- Large, heavy limbs extend over a home, garage, or high-traffic area.
A+ Tree and Crane can determine the best course of action and help preserve trees when possible while removing hazards when necessary.
