Sometimes, a tree’s condition can pose a real danger to people and surrounding structures. Recognizing the signs of a hazardous tree is crucial for preventing accidents and avoiding costly damage. At Bassett Tree Service, we provide hazardous tree removal in the greater Mesa, AZ area. Here are five warning signs that a tree on your property may be a safety risk.


Significant Leaning

A tree that is noticeably leaning—especially if it wasn’t leaning before—can be a sign of serious structural weakness or root instability. While some trees naturally grow at an angle, a sudden or increasing lean often indicates that the tree is losing its ability to support its own weight, making it more likely to fall during a storm or high winds.


Splits in the Trunk

Deep cracks, splits, or cavities in a tree’s trunk can severely weaken its structural integrity. These issues may result from storm damage, disease, or old age. A compromised trunk can fail unexpectedly, causing large sections—or the entire tree—to come down without warning.


Dead/Falling Branches

Frequent falling branches or a canopy filled with dead limbs are clear signs of decline. Dead branches are brittle and can break off easily, posing a risk to anyone below. If large sections of the tree’s canopy are dead, it often points to underlying health problems that could lead to the tree’s complete failure.


Root Damage or Decay

Healthy roots are essential for a tree’s stability and nutrient intake. Signs of root trouble include visible decay at the base of the trunk or soil movement around the tree after strong winds. Root damage can make a tree unstable, increasing the likelihood of it toppling over.


Signs of Disease or Infestation

Diseases and pests can weaken a tree from the inside out. Common indications include discolored leaves, unusual bark patterns, or the presence of boring insects. Left untreated, these problems can spread to other trees and further compromise the affected tree’s health and stability.
