10 Signs a Tree Needs to Be Removed

Dead branches over 2 inches in diameter that hang over your home, driveway, or yard are the most immediate hazard. They can fall without warning, especially during storms. If you see large dead limbs in the upper canopy, call a tree expert — don't wait for the next storm to decide for you.

A slight lean is normal for many trees. A sudden or progressive lean — especially toward your house, garage, or power lines — is a red flag. Check for soil heaving or cracking on the opposite side of the lean, which indicates root failure.

A hollow trunk doesn't automatically mean removal — some trees live for decades with internal decay. But when the decay affects more than one-third of the trunk's circumference, structural integrity is compromised. Probe suspect areas with a screwdriver; soft, punky wood is a warning sign.

Mushrooms, conks, or shelf fungi growing from the trunk or root flare indicate internal wood decay. Armillaria (honey fungus) at the base is particularly serious — it attacks the root system and can kill a tree from the ground up. Fungal fruiting bodies are the visible sign of decay that may already be extensive.

Healthy trees shed bark in small pieces as they grow. Large sections of bark falling off, or areas where bark is missing and the wood beneath is discolored or soft, indicate serious disease or death of that section of the tree.

Deep vertical cracks or splits in the main trunk or major scaffold branches are structural failures waiting to happen. Co-dominant stems (two trunks growing from the same point) with included bark are especially prone to splitting under wind or ice load.

Construction within the drip line, trenching, soil compaction, or grade changes can kill a tree's root system — often with a 2–5 year delay before visible symptoms appear. If major roots have been cut or buried, have the tree assessed even if it still looks healthy.

A tree that has lost more than half its canopy to disease, drought, insects, or storm damage has a poor prognosis. While some trees can recover from significant canopy loss, a tree at 50%+ decline is unlikely to fully recover and poses increasing hazard risk.

Dead trees don't always fall immediately — some stand for years. But a dead tree has no living tissue to resist decay, and its structural integrity deteriorates steadily. Scratch a small section of bark: green or white tissue underneath means the tree is alive; brown or dry means it's dead.

Sometimes a tree is structurally sound but in a location that creates ongoing problems: roots damaging foundations or sewer lines, branches over the roof dropping debris, or a species that's simply too large for the space it's in. Proactive removal before problems escalate is often the most cost-effective choice.
