TL;DR: Most trees give clear signals before they fail. Dead branches, a noticeable lean, fungus at the base of the tree, bark damage, and a hollow trunk are all indicators that a hazard may be developing. Catching these early can protect your home, your family, and your property, and it almost always costs less than waiting for an emergency.
Many Trees in Central Indianapolis Are Quietly Becoming Hazards
Many trees across Fishers, Carmel, Geist, and Noblesville have been standing for decades, shading backyards and lining driveways throughout Hamilton and Marion counties. They add real beauty and real value to residential properties.
But those same specimens can become serious hazards when the health of your tree declines without anyone noticing. Heavy snow loads, severe spring storms, and the ongoing spread of the Emerald Ash Borer have made it more important than ever for local homeowners to pay attention.
Dead or dying trees do not always look dangerous. A specimen that appears stable on the outside can be severely stressed or hollowed out internally, and when conditions are right, it can come down fast. Knowing what to look for, and when it's time to remove a tree from your yard, can make the difference between a planned job and a crisis.
The Real Problem: Most Homeowners Wait Too Long
Many trees that cause property damage each year were showing clear indicators of decline months before they fell. The problem is that most homeowners do not recognize those indicators until something has already gone wrong.
A hazardous tree can fall on a home, a vehicle, a fence, or power lines and cause injury to anyone in its path. The consequences go well beyond the cost of taking it down.
Most homeowners call a tree company only after something breaks. A branch drops onto a roof. A windstorm exposes a rotted core. A storm topples a large specimen onto a structure. These events are not random. They are the end result of a process that presented multiple opportunities to act earlier.
When a specimen is a safety risk, acting on it is the responsible decision. Dead or dying trees left in place do not get better on their own.
8 Signs a Tree Needs to Be Removed
1. Dead or Dying Branches in the Upper Canopy
Dead branch stubs and lifeless tree limbs in the upper canopy are among the clearest indicators that something is wrong. Healthy trees shed the occasional branch, but widespread dieback across the crown is a different situation entirely.
When large branches stop producing leaves and bark begins to pull away, those limbs are no longer receiving water or nutrients. That process can accelerate quickly. Large branches in this condition, sometimes called widow makers, can fall without warning, even on calm days.
If more than a quarter of the canopy shows dead or deteriorating limbs, the specimen is unlikely to recover without professional intervention. At that point, the question is not whether to act. It is how quickly.
2. A Noticeable or Sudden Lean
Not every lean means trouble. Many trees develop a gradual lean as they grow toward light, and that kind of lean can be stable for a long time. Leaning trees become a concern when the lean develops suddenly, progresses over time, or appears after a storm or period of saturated ground.
A leaning tree may be losing its grip on the soil. Signs of root failure include soil cracking or heaving on the side opposite the lean, exposed roots pulling up from the ground, or a new lean that was not there last season. A leaning tree may also indicate that the root system is already failing beneath the surface.
When a specimen is directing its weight toward a structure, power lines, or a high-traffic area, it warrants immediate attention. Do not wait on this one.
3. Fungi Growing at the Base or on the Trunk
Mushrooms growing at the base of the tree or shelf fungi appearing on the bark are not cosmetic issues. Fungi growing on a living specimen indicate that the wood inside is breaking down. Fungus decomposes the structural tissue the plant depends on to stay anchored and upright.
The presence of fungus at the base of the tree is particularly serious. It may indicate root rot, which compromises the ability to anchor in the ground. A specimen can look completely normal on the outside while being structurally unsound inside.
Many homeowners see mushrooms growing near a tree and assume it is a soil issue. It may indicate that the tree is already in serious decline. This one warrants a professional assessment.
4. Cracks, Splits, and Bark Damage
The trunk is the structural backbone of any mature specimen. Vertical cracks, horizontal splits, or areas where bark has separated and peeled away may indicate that the tree is damaged or under significant stress.
Inspect the tree's trunk carefully for cankers, which are sunken, discolored sections of dead tissue caused by disease or fungal infection. Trees with multiple trunks can be especially vulnerable here, as attachment points between co-dominant stems are often weak. When a canker wraps most of the way around the trunk or appears at a major branch junction, pruning alone will not address the underlying problem.
Open wounds from past storms or improper cuts also serve as entry points for insects and disease. If the tree isn't showing new growth around an old wound after a couple of growing seasons, that is a signal worth taking seriously.
5. A Tree Is Hollow at the Core
When a tree is hollow, it does not automatically mean it comes down. Specimens can wall off internal decay and live for years with some degree of hollowing. But when the cavity takes up more than one-third of the trunk's diameter, structural integrity is significantly reduced.
Combine a hollow core with other factors like leaning, fungal growth, or bark damage, and the case for removal becomes much stronger. You can sometimes identify internal issues by knocking on the trunk at several points. A hollow sound where you expect solid wood is a reason to have a professional inspect it.
Dead branch stubs on an otherwise live specimen can also point to internal decay that has not yet reached the surface.
6. Signs of Root Damage or Failure
Tree roots are what keep a specimen anchored, and damage to the root zone does not always appear above ground right away. Signs of root stress can take two to five years to show up after the damage occurs.
Look for signs of root disturbance: soil disrupted by construction or trenching, areas where tree roots have been cut, compacted soil from heavy equipment, or grade changes that have buried the root zone. A specimen growing close to a driveway, foundation, or utility trench is more likely to have compromised roots.
Epicormic shoots are small sprouts that emerge from the base or lower trunk of a severely stressed tree. They are another indicator of systemic problems. Healthy trees do not typically produce them in large numbers. Clusters of small shoots at the base may indicate the specimen is under more stress than it appears.
7. Proximity to Structures, Power Lines, or High-Traffic Areas
Not every specimen that should be removed is sick. Sometimes the issue is location. A tree that is growing close to your home, hanging over the roof, or growing into power lines is a concern even if it is structurally sound.
Large trees should be at least 20 feet from a home's foundation where possible. Trees should be at least that distance from structures, particularly when they have wide canopies or aggressive root systems. A specimen growing close to your home and also showing any other indicator on this list deserves prompt evaluation.
Trees growing into power lines always need specialized handling. This is not a DIY situation. Contact your utility provider or a qualified tree service before attempting any trimming near utility lines.
8. Storm Damage and Structural Weakness
Indiana storms can leave large branches cracked, trunks split, or root systems destabilized, sometimes in ways that are not immediately obvious. Heavy snow accumulation causes the same kind of damage, especially on specimens that already have a compromised canopy or a narrow branch structure.
After any significant weather event, walk your property and inspect trees close to your home, outbuildings, and play areas. Look for hanging limbs, splits at the crotch of major branches, bark that has been torn away, or any new lean that was not there before the storm. A specimen that survived but looks different afterward may need immediate attention even if it is still standing.
Common Tree Species in Central Indiana and Their Specific Risks
Oak Trees
Oaks are among the most valued specimens across the Indianapolis area. They are long-lived, structurally strong, and add significant property value. Healthy trees in the oak family can live for well over a century under the right conditions.
But oaks are susceptible to oak wilt, a fungal disease that spreads through root contact between specimens growing close together. Infected red oaks can decline and die within a single growing season. Because the fungus moves underground, removing one affected specimen may not protect nearby trees without proper treatment of the root zone.
Look for browning that progresses from the leaf tips inward, rapid leaf drop during the growing season, or dark staining visible under the bark. Dead oak wood becomes brittle quickly, increasing the fall hazard of large limbs.
Maple Trees
Silver maples, common in older Indianapolis-area neighborhoods, are fast-growing but structurally weaker than many other species. They tend to develop narrow, V-shaped branch angles that are prone to splitting under heavy snow or during storms. Trees with multiple trunks, a common growth pattern in silver maples, carry a higher structural concern than single-trunk specimens.
Maples are also susceptible to verticillium wilt, a soilborne disease that causes dieback on one side of the canopy first. If one branch cluster dies while surrounding branches remain healthy, that pattern may indicate a systemic disease rather than a mechanical issue.
Ash Trees
The Emerald Ash Borer has worked through ash populations across Indiana significantly. This invasive insect works beneath the bark, cutting off the ability to transport water and nutrients. Infested specimens that are not treated in time typically decline within two to four years.
Watch for a thinning upper canopy, D-shaped exit holes in the bark, S-shaped feeding galleries visible under loose bark, epicormic shoots at the base, and woodpeckers and other wildlife feeding heavily on the trunk. Woodpeckers and other wildlife target the larvae, so unusual pecking activity is a meaningful clue worth noting.
An ash tree in advanced decline becomes a hazardous tree quickly. The wood becomes brittle and unpredictable. If ash specimens on your property have not been evaluated recently, schedule that assessment now.
Trimming vs. Removal: How to Tell the Difference
Not every specimen with a problem needs to come down. Tree pruning and targeted trimming can extend the life of many trees when the underlying structure is still sound. Knowing when each approach applies helps you make a confident, informed decision.
You don't always need removal when:
- Dead or crossing branches are a concern but the main structure is healthy
- The canopy has grown too dense and you want to prune for better airflow and light
- Specific limbs are growing into power lines or close to a structure
- Storm damage is limited to a few tree limbs without affecting the core
- The goal is to improve long-term tree care and extend the canopy's life
Professional tree removal is the right call when:
- More than half the specimen is dead or structurally compromised
- The root system is failing
- Decay has reached the structural core
- The tree is dead, and a dead tree with no viable path to recovery poses an active fall hazard
- A diseased tree has progressed beyond what treatment can address
- Removing the tree from your property is the only way to eliminate the risk to neighboring structures or people
- You want to prune but the structure cannot support the weight reduction safely
A tree isn't always easy to evaluate from the ground. Arborists are trained to assess what is happening inside and above. Once a tree removed from the wrong list is left standing, or one that should stay gets taken down, that decision is hard to undo. Consulting a professional before you decide prevents costly mistakes in either direction.
When to Consult a Certified Arborist
An ISA Certified Arborist is a tree care professional who has passed a comprehensive industry exam and maintains ongoing continuing education. When you consult a certified arborist, you are getting a trained evaluation grounded in ISA standards, not a guess and not a sales pitch.
At Broken Oak Tree Service, Kevin Wright is our ISA Certified Arborist with eight years of hands-on experience. He performs formal risk assessments using established criteria and can determine whether a specimen can be preserved through tree pruning and treatment, or whether it should come down. Our arborists approach every property the same way: look at everything, not just the one you called about.
You should hire a professional for a formal assessment when:
- You notice one or more of the indicators described in this post
- A significant storm has affected specimens close to your home
- You are preparing to sell your property and want to identify any related liability
- Construction or landscaping work has occurred near mature specimens
- A neighbor or utility provider has raised a concern
Our goal is to help you make a sound, informed decision, not to upsell you on work you do not need.
Do I Need a Permit to Remove a Tree in Indianapolis, Indiana?
For most homeowners on private residential property, the answer is no. Indiana does not have a statewide permit requirement for standard residential removal.
That said, there are three exceptions worth knowing:
Historic districts: Some neighborhoods fall under local preservation ordinances that require notification or approval before removing significant specimens. If your home is in a designated historic district, check with the Indianapolis Historic Preservation Commission before scheduling work.
HOA communities: Many planned communities in Carmel, Fishers, and Noblesville have covenants that require HOA approval for removal, particularly for specimens above a certain trunk diameter. Skipping this step can result in fines.
City-owned trees: If a tree is in the right-of-way, a utility easement, or on city property adjacent to your home, contact the relevant municipality before doing anything. That specimen may not be yours to touch.
A quick call to your HOA or city planning office answers this in minutes and avoids complications.
Expert Insight: What We See in the Field
Our crew has been doing this work since 2015, serving homeowners across Fortville, Geist, Fishers, Noblesville, Carmel, Greenfield, Westfield, McCordsville, and Pendleton. A few patterns come up consistently.
Large trees close to homes are among the most common situations we encounter. A homeowner calls about one branch, and when we arrive, we can see the specimen has been under stress for years. The branch is a symptom. The root system, the bark, the canopy: they tell the full story once you know what to look for.
One situation that stands out: a client building a new home on a wooded lot wanted to preserve as many mature specimens as possible, but the construction company wanted to clear the entire site. Our team walked the property, identified which ones could live for years without structural compromise given the planned elevation changes, and helped her keep several that would otherwise have been removed. Healthy trees that are structurally sound and properly situated add real value. But identifying which specimens actually meet that standard requires someone who knows what they are looking at.
Decay works from the inside. Fungus appears at the base. Tree roots weaken beneath the surface. By the time a specimen is visibly deteriorating on the outside, internal decline has often been underway for a long time. Inspect trees on your property at least once a year, especially large trees near structures or play areas.
Quick Answers
What are the most common signs a tree needs to be removed?
Dead or dying branches, a noticeable lean, fungal growth at the base, cracks in the tree's trunk, hollow sections, and root damage are the most reliable indicators. When several of these appear together, it is time to remove your tree or at minimum have it professionally assessed.
How do I know if a leaning tree is dangerous?
Leaning trees are not always a concern. A gradual, long-established lean is often structural and stable. But a leaning tree may be dangerous when the lean developed suddenly or is getting worse. If the soil near the base is heaving or cracking, the tree may be uprooting and warrants immediate attention.
Can a diseased tree be saved, or does it need to be removed?
It depends on how far along the disease is. Consult a certified arborist before making that call. If the condition was treated in time, pruning and targeted care may be enough. If more than half the structure is compromised, it should probably be removed.
Do I need a permit to remove a tree in Indianapolis, Indiana?
Indiana does not require a statewide permit for tree removal on private property. However, homes in historic districts or neighborhoods with active HOA rules may require prior approval. Always check with your local municipality or HOA before scheduling any work.
Is it cheaper to remove a tree now or wait?
Acting early is almost always more affordable. Emergency removal after a failure typically costs significantly more than a planned job. The longer a severely stressed specimen stays in place, the greater the potential for property damage.
Bottom-Line Summary
Dead branch stubs or widespread limb dieback, a leaning tree that has recently shifted, fungi growing at the base or on the bark, cracks in the tree's trunk, a hollow core, root damage, and large trees growing into power lines or hanging over the roof: these are the indicators that a specimen may be becoming a hazardous tree and it's time to act.
Healthy trees that are well-maintained can live for years without posing a concern. But specimens that are declining, diseased, or in the wrong location are a different situation. Knowing the difference, and having a qualified professional help you make that call, is what keeps property and people safe.
Acting early is almost always less expensive, less disruptive, and safer than responding to a failure. Do not wait for a storm to make the decision for you.

Key Takeaways
- Dead branch stubs and large branches with no bark or leaves are a clear indicator the specimen's health is in decline. Widespread dieback means it is unlikely to recover without intervention.
- Leaning trees that have developed a new lean, or that show soil heaving at the base, need immediate attention. The root system may already be failing.
- Fungi growing at the base of the tree or on the bark signals internal breakdown. Mushrooms growing near the base are not a minor landscaping issue.
- Epicormic shoots at the base or lower trunk indicate a severely stressed tree. Combined with thin canopy or bark damage, this may mean it should probably be removed.
- A tree that is hollow in the structural zone, meaning the cavity exceeds about one-third of the trunk's diameter, has significantly reduced ability to withstand a storm.
- Trees with multiple trunks, or hazardous trees growing into power lines or hanging over the roof, carry elevated concern even when they appear otherwise healthy.
- Indiana does not require a permit for most private tree removal, but historic districts and HOA communities are exceptions worth confirming before you schedule any work.
- Consult a certified arborist when you are unsure. Our arborists help you make a sound decision based on what the specimen actually shows, not guesswork.
- It is almost always less costly to remove a tree proactively than to deal with damage after a failure. Professional tree removal services handled early are far better than emergency response.
