How to Tell if a Big Tree Is Posing an Immediate Threat to Your Home

A Sun State Tree Service • 18 August 2025

Mature trees can become serious hazards if they show signs of instability or decline. A large tree that is structurally compromised or growing too close to your home can present a danger to both people and property, especially during storms. Knowing the warning signs of a tree that may be an immediate threat allows you to take action before disaster strikes. At A Sun State Tree Service, our local arborists can identify and safely remove dangerous trees. Here are five signs that a big tree could be endangering your home.


The Tree Is Leaning Toward the House

A slight natural lean isn’t always a concern, but if a tree is suddenly leaning or appears to be shifting its posture toward your home, it could be unstable. A tree that has developed a significant lean, particularly after a storm or heavy winds, may have root or trunk damage that compromises its ability to remain upright. When the lean is directed toward your house, the risk of damage increases dramatically in the event of a collapse.


Large, Dead Branches Over the Roof

Big trees with dead or dying limbs hanging over your roofline are cause for concern. Dead branches can break off without warning, especially during high winds. If these limbs are large and situated directly above your home, they could cause significant roof damage. A professional arborist should inspect the tree to determine whether pruning or full removal is necessary.


The Tree Has Splits in the Trunk

Visible cracks or splits in a tree’s trunk are signs of serious internal stress. These structural issues can occur from disease, pests, or old storm damage that never healed properly. A compromised trunk may not be able to support the tree’s weight, especially during adverse weather conditions. If the damaged trunk is part of a tree that leans toward your home or sits close to the foundation, it may pose an urgent threat.


Root Damage or Uplift Is Visible

The health of a tree’s root system is key to its overall stability. If you notice raised soil or exposed roots, the root structure may be failing. Construction activity or soil erosion could contribute to root destabilization. A tree that has lost its anchoring ability is at high risk of toppling and should be professionally assessed immediately.


Fungus or Rot Is Present at the Base

Fungal growth or soft, decaying wood around the base of a large tree are warning signs of internal rot. Once decay sets in at the roots or lower trunk, the tree’s structural integrity may be significantly weakened. A rotting tree may appear stable on the outside but could fall with little provocation.
