The short answer: The most common warning signs that a tree is dying or dangerous are large dead branches, cracks or splits in the trunk or major limbs, a new or worsening lean, mushrooms or fungal growth at the base or on the trunk, lifted or cracked soil and exposed roots on one side, a hollow or cavity in the trunk, bark peeling away in large areas, and dead sections in the canopy or failing to leaf out in spring. If you see any of these on a tree near your home, driveway, or power lines, have an ISA Certified Arborist assess it. JCS Tree Care Professionals offers free on-site tree assessments across Metro Detroit, call (248) 965-9035.
Warning signs to look for
- Large dead branches. Bare, brittle limbs with no leaves in the growing season, especially big ones over a roof, driveway, or walkway.
- Cracks or splits. Vertical cracks, seams, or splits in the trunk or where major limbs meet the trunk are a structural red flag.
- A lean. A tree that has always leaned slightly may be fine, but a new or increasing lean, especially after a storm, is a warning sign.
- Mushrooms or fungal conks. Mushrooms at the base, or shelf-like conks on the trunk or roots, often signal internal or root decay you cannot see from the outside.
- Root or soil problems. Heaving, lifted, or cracked soil on one side of the tree, or exposed and damaged roots, can mean the root system is failing.
- A hollow or cavity. Open cavities, deep hollows, or soft, crumbling wood reduce a tree strength.
- Bark falling away. Large areas of missing or peeling bark, or smooth dead patches, point to a dying section.
- Canopy dieback. Dead limbs scattered through the crown, thinning leaves, or a whole side that never leafs out.
Which signs are urgent
Some issues can wait for a planned assessment; others should not. Call promptly if you see a fresh lean or a tree that shifted during a storm, large dead or cracked limbs hanging over your house, driveway, or where people walk, cracks or splits in the trunk or a major fork, or soil heaving and roots lifting on one side. Hazardous and storm-damaged trees are handled any time of year, a tree threatening a home or people should not wait for a season.
Why an assessment matters
Not every tree with a dead branch needs to come down, sometimes the right answer is targeted pruning, and sometimes a tree that looks fine is failing at the roots. That is why a trained eye matters. At JCS Tree Care Professionals, your free on-site assessment is done by an ISA Certified Arborist, who evaluates the tree health and structure and recommends the right plan, pruning, monitoring, or removal. If removal is the answer, we handle large and technical takedowns across Oakland County and Metro Detroit, and we clean up the site when we are done.

Frequently Asked Questions
How do I know if my tree is dying?
Signs a tree is dying include large dead or bare branches in the growing season, dead sections in the canopy, bark falling away in big patches, mushrooms or fungal conks at the base, and a trunk that is hollow or crumbling. A tree can also be failing at the roots while the top still looks green. An ISA Certified Arborist can tell for certain, JCS Tree Care Professionals offers free assessments across Metro Detroit at (248) 965-9035.
Is a leaning tree dangerous?
A tree that has always leaned slightly is often stable, but a new or increasing lean, especially after a storm or with soil lifting on one side, is a warning sign that the tree may be failing and should be assessed promptly. JCS Tree Care Professionals evaluates leaning trees across Oakland County and Metro Detroit; call (248) 965-9035.
Are mushrooms growing on my tree a bad sign?
Often yes. Mushrooms at the base, or shelf-like conks on the trunk or roots, usually indicate internal or root decay that weakens the tree even when the outside looks normal. It is worth having it assessed. JCS Tree Care Professionals offers free on-site tree assessments, call (248) 965-9035.
Should I remove a tree with a large dead branch?
Not always, sometimes the right fix is removing the dead limb rather than the whole tree, and sometimes the tree is too far gone to save. A large dead branch over a home, driveway, or walkway should be assessed promptly. An ISA Certified Arborist at JCS Tree Care Professionals can recommend pruning versus removal; call (248) 965-9035.

An ISA Certified Arborist is the right professional to evaluate whether a tree is safe or needs work. At JCS Tree Care Professionals, your free on-site assessment across Metro Detroit is done by an ISA Certified Arborist. Call (248) 965-9035.
