- The Tree Is Leaning
A tree that suddenly starts leaning should be checked. A new lean may mean the roots or trunk have been damaged.
Pay special attention if the tree is leaning toward your house, garage, driveway, or another structure. - There Are Dead Branches
Dead branches can break and fall without warning. Large dead branches are especially dangerous when they hang over your roof, vehicles, or areas where people walk.
Look for branches with no leaves, loose bark, or other signs of damage. - The Trunk Has Large Cracks
Deep cracks or splits in the trunk can weaken a tree. Look for cracks that run along the trunk or large branches.
A tree may still have green leaves while serious damage is hidden inside. - Roots Are Damaged
Roots help keep a tree standing. Construction, digging, storms, and soil changes can damage the root system.
Look for exposed, broken, or damaged roots around the base of the tree. A tree with major root damage may become unstable. - The Tree Is Too Close to Your Home
A large tree does not have to be sick to become a hazard. A tree growing close to your home may cause problems if large branches break or the tree falls during a storm.
Trees near roofs, power lines, driveways, and other structures deserve special attention. - You See Signs of Decay
Holes, soft wood, missing bark, and mushrooms growing on or near the tree may be signs of decay.
Decay can make a tree weaker than it looks. A professional inspection can help determine how serious the problem may be.
