A weak or damaged tree can fall unexpectedly, causing damage to homes, vehicles, power lines, and people. Storms, high winds, or heavy snowfall can accelerate this risk. Proactively inspecting your trees can prevent accidents, lower maintenance costs, and keep your surroundings safe.
Key Signs of a Hazardous Tree
1. Leaning or Tilting Trees
A tree that suddenly starts leaning is a major red flag. While some trees grow at an angle naturally, a sudden lean may indicate root damage or structural instability. Factors such as soil erosion, underground construction, or root decay can cause a tree to shift.
What to Look For:
- A tree that is leaning more than 15 degrees from vertical.
- Recently exposed roots at the base of the tree.
- Soil cracking or upheaval around the tree’s roots.
2. Hollow or Decayed Trunks
A tree with a hollow trunk might still be alive, but it’s significantly weaker than a solid tree. Hollow or decayed trees have reduced structural integrity and are more prone to breaking, especially in extreme weather conditions.
Signs of Trunk Decay:
- Large cavities or open wounds in the trunk.
- Soft, crumbly, or spongy wood.
- Sawdust-like material around the base, which could indicate insect activity.
3. Large Dead or Broken Branches
Dead branches, especially those hanging over driveways, sidewalks, or roofs, pose a significant risk. These branches can snap off unexpectedly, causing injury or property damage.
What to Watch For:
- Brittle branches that break easily.
- Branches with no leaves or buds in growing seasons.
- Sections of the tree that appear lifeless compared to the rest.
Regular pruning can remove dead branches and reduce hazards.
4. Exposed or Damaged Roots
Roots provide stability for trees. When they are compromised, the entire tree becomes unstable. Construction projects, heavy vehicle traffic, or soil erosion can damage roots and increase the risk of tree failure.
Signs of Root Problems:
- Large roots that appear severed or decayed.
- Fungal growth around the tree’s base.
- A tree that moves excessively in the wind.
What to Do If a Tree Shows These Warning Signs?
If you notice any of these hazards, take action immediately:
- Inspect the tree closely – Look for worsening symptoms over time.
- Consult a certified arborist – A professional can evaluate the tree and recommend solutions.
- Prune or remove as needed – Trimming weak branches can help, but if the entire tree is a risk, removal might be necessary.
- Check your insurance – If the tree causes damage, your homeowner’s insurance may help cover the costs.
Preventing Tree Hazards
Regular tree maintenance is the best way to prevent hazards. Conduct seasonal inspections, prune weak branches, and ensure trees have a healthy environment to grow. If you notice signs of weakness early, you can often save the tree before it becomes a threat.
