Most trees live for decades with little fuss, but a declining or structurally compromised tree can become a real hazard — especially during one of metro Atlanta's storms. Knowing the signs a tree needs to be removed helps you act before a falling limb or trunk damages your home, vehicle, or a neighbor's property. Below are the seven warning signs our ISA Certified Arborists watch for, what each one looks like, and why it matters. Keep in mind that not every troubled tree must come down. Some problems can be corrected with professional tree trimming or treatment, which is why a hands-on assessment is always worth it.
1. Large Dead Branches and Heavy Deadwood
Scan the canopy for bare limbs that never leafed out, brittle gray branches, or large sections that snap rather than bend. A few small dead twigs are normal, but when major limbs die back — especially toward the top — it signals the tree is struggling to move water and nutrients. Why it matters: dead branches can drop without warning, and widespread deadwood often points to root or vascular problems. Isolated deadwood can frequently be pruned out; canopy-wide dieback usually means deeper decline.
2. Trunk Cracks, Cavities, and Visible Decay
Look for deep vertical cracks (called seams), open cavities, oozing fluid, peeling bark, or soft, crumbling wood. A single shallow crack may be cosmetic, but a deep split or large cavity weakens the trunk's load-bearing core. Why it matters: a compromised trunk can fail suddenly under wind or its own weight. Cabling or pruning sometimes helps minor defects; significant trunk decay often warrants removal.
3. A Sudden or Worsening Lean
Trees that grew at an angle their whole life are usually fine. The red flag is a new or increasing lean, especially with cracked or heaving soil on the side opposite the tilt. Why it matters: a fresh lean means the root plate may be lifting or the roots are failing. A young tree with a mild lean can sometimes be stabilized, but an established tree that has suddenly shifted is often unsafe to keep.
4. Mushrooms or Fungus at the Base (Root Rot)
Shelf-like fungal conks growing on the trunk or clusters of mushrooms erupting from the soil over the roots are a classic warning. Why it matters: these fruiting bodies usually indicate internal wood decay or root rot — the tree may be hollowing out where you can't see it. Because fungal decay attacks the very structure holding the tree up, it frequently tips the decision toward removal.
5. Heaving Roots and Soil Movement
Walk the base after a windy day. Roots or soil lifting on one side, a mounded or cracking root zone, or visibly girdling roots strangling the trunk all point to anchorage trouble. Why it matters: the root system is the tree's foundation. When it loosens or fails, the entire tree can topple even though the canopy looks healthy. Construction, trenching, or grade changes near the roots are common culprits.
6. A Hollow Trunk
Tap the trunk and listen for a hollow sound, or look for openings that reveal an empty core. A tree can survive with some hollowing because the living, structural wood is in the outer rings. Why it matters: once roughly a third or more of the trunk's wall is gone, its strength drops sharply. An arborist can sound and measure the remaining shell to judge whether the tree is still safe or needs to come down.
7. A Dead Leader or No Leaves in Season
If the central top stem (the leader) is dead, or the tree stays bare while everything around it has leafed out in spring, the tree is likely dying or dead. Why it matters: a fully dead tree continuously loses strength as the wood decays, becoming more brittle and unpredictable every season. Confirm it isn't simply late-leafing or dormant first — but a confirmed dead tree should be removed before it fails on its own.
Urgent: If a tree showing any of these signs stands within falling distance of your house, garage, driveway, or a power line, treat it as a priority. A failure in those spots can cause serious property damage or injury. Call an arborist promptly — do not approach lines yourself.
Removal Isn't Always the Answer
It's easy to assume the worst, but many of these issues are treatable. Deadwood can be pruned, weak unions can be cabled, and a stressed tree can often recover with proper care. The trick is correctly reading how much of the structure or root system is compromised — something that takes a trained eye. An ISA Certified Arborist evaluates the whole tree, weighs the risk against the target below it, and recommends the least drastic safe option. When the structure truly is beyond saving, prompt, professional tree removal is the responsible choice.
Quick Reference: Treat or Remove?
| Sign | Often Treatable | Usually Remove |
|---|---|---|
| A few dead branches | Prune | — |
| Canopy-wide dieback | — | Likely |
| Minor surface crack | Monitor / cable | — |
| Deep trunk split or cavity | — | Likely |
| Root rot / base fungus | Rarely | Likely |
| Sudden lean with soil heave | — | Yes |
| Confirmed dead tree | — | Yes |
