What are the Signs that a Tree Needs a Risk Assessment?

Identifying early warning signs is critical for preventing sudden tree failure and property damage. According to Miller Tree Service and industry guidelines, you should seek a professional risk assessment if you observe any of the following indicators:

Physical Structural Issues

  • A tree lean exceeding 15 degrees, which may suggest root failure.
  • Vertical or horizontal trunk cracks that weaken the tree’s structure.
  • Loose bark or visible cavities that reveal internal rot.

Growth and Health Indicators

  • Crown dieback or deadwood affecting more than 50 percent of the tree.
  • The presence of mushroom fungi at the base of the tree, signaling internal decay.
  • Discolored leaves or dead branches.

Root and Ground Changes

  • Heaving soil around the roots, indicating instability or uprooting.
  • Recent root damage caused by nearby construction.

If you notice multiple signs, the level of urgency increases. It is recommended to document these issues with photos and contact an ISA-certified arborist to conduct a formal evaluation using methods such as visual inspection, sounding, or probing.
