4 Signs that a Big Tree Is at High Risk of Suddenly Toppling

Pete & Ron’s Tree Service • 3 October 2025

When tall trees become unstable, they can quickly turn into serious safety hazards. A falling tree can cause significant damage to homes, vehicles, and power lines—and even put lives at risk. While healthy trees are generally stable, certain signs indicate that a tree may be at risk of suddenly toppling. At Pete & Ron’s Tree Service, we provide expert hazardous tree identification and removal in the greater Tampa, FL area. Being aware of these warning signs allows you to act quickly and call a professional arborist before disaster strikes.


Leaning or Shifting Position

A tree that has started leaning suddenly or has increased its tilt over time may be in danger of falling. While some trees do grow at an angle, a new or worsening lean often points to instability in the roots or soil. You might also notice cracks in the ground near the base or exposed roots on one side, suggesting that the tree’s foundation is compromised. These are strong indicators that the tree could topple in strong winds.


Cracked Trunk

The trunk serves as the main support structure for a tree. When it develops large cracks, cavities, or splits, the tree’s stability is severely weakened. A split trunk often results from storm damage, lightning strikes, or internal decay. Once a tree’s core is compromised, it can fail suddenly under its own weight. If you see deep fissures or hollow areas in a large tree’s trunk, it’s important to have it inspected right away.


Damaged or Decaying Roots

Roots anchor a tree and absorb vital nutrients. When they become diseased, decayed, or damaged, the entire tree can become unstable. Signs of root problems include fungus or mushrooms growing around the base, heaving soil, or visible rot. Because much of the root system is underground, damage often goes unnoticed until it’s too late. If you suspect root issues, an experienced arborist can assess the extent of decay and determine whether removal is necessary.


Fungal Growth and Internal Decay

The presence of fungi on the trunk or base is a warning sign of internal rot. Even if the tree appears relatively healthy from the outside, decay inside the wood can destroy its strength. A hollowing or spongy trunk means the tree may no longer be able to support its own weight.
