What Are Signs of a Dying or Dangerous Tree?
Spotting a dying or dangerous tree before it becomes a serious problem is essential for any Westlake homeowner. Trees don’t suddenly fail – they give warning signs that something’s wrong.
Whether it’s storm damage, disease, or age, trees show distress in predictable ways. Dead branches, unusual lean, root problems, or canopy changes all signal potential trouble ahead. If you’re seeing any of these, check out our guide on signs of a dying or dangerous tree to learn what to look for.
This guide covers the most common warning signs, what they mean, and when to take action. Catching problems early saves thousands in property damage and keeps your family safe. If storm damage is the cause, our emergency tree services are available when you need help fast. At Timberline Tree Experts, we help Westlake homeowners identify tree risks before emergencies occur. We offer free safety assessments for peace of mind.
Common Warning Signs
Trees usually don’t fail without warning. Before a branch falls or a tree tips over, there are signs that something’s off. You might notice dead limbs, cracks in the trunk, strange lean, or roots lifting out of the ground. These changes aren’t just cosmetic – they can be signs of serious internal damage or decay. Knowing what to look for can help you act before things get dangerous or costly. In this section, we’ll walk through the most common red flags so you can spot trouble early and protect your property.
Visual Indicators of Tree Distress
- Trees communicate health through visible changes most homeowners can spot. Dead or dying branches scattered throughout the canopy are the first red flag.
- Unusual lean is a major concern. While some trees naturally grow at slight angles, sudden changes in lean or severe tilting means root failure or structural damage.
- Bark problems like peeling, cracking, or missing sections expose trees to infection. Fungal growth around the base or trunk is particularly concerning since it suggests internal decay.
- Root exposure from erosion or construction damage weakens the tree’s foundation and stability.

Seasonal Warning Signs
Trees respond to the seasons just like everything else in your yard, but not all changes are normal. Some issues only show up during certain times of year – like sudden leaf drop in summer, or branch cracking in winter. If you’re not sure whether your tree is reacting to the weather or signaling deeper problems, it’s important to pay attention. This section will help you tell the difference between natural seasonal shifts and signs that your tree might be in trouble.
1. Dead Branches
Branches that are dry, brittle, or snapping off easily are often the first sign your tree is in trouble. They can fall without warning, especially during wind or storms.
2. Sudden Lean
If your tree suddenly starts leaning or shifts its posture, it could mean the roots are weakening or the soil is unstable. This is a major red flag for possible failure.
3. Cracks in the Trunk
Deep splits or vertical cracks in the trunk can signal structural issues. These weak points may cause the tree to break or split during heavy weather.
4. Root Damage
Exposed, rotting, or lifted roots are a sign the tree’s foundation is failing. Since roots anchor the entire tree, visible damage here should never be ignored.
5. Thinning Canopy
If the top of your tree looks bare or patchy while the rest seems fine, it might be dealing with disease, pests, or internal decay. This slow decline can lead to a full die-off.
Structural Problems
Not all tree problems are easy to spot, but structural issues are a big deal when it comes to safety. Cracks in the trunk, split branches, or an unbalanced shape can all point to a tree that’s at risk of falling. These problems usually develop slowly, but once they reach a certain point, failure can happen fast. In this section, we’ll cover the most common structural warning signs and what they might mean for your tree’s health and stability.
1. Cracks and Splits
Long cracks in the trunk or major limbs can weaken the tree’s structure. These often form after storms or freeze-thaw cycles and may lead to sudden breaks if not addressed.
2. Co-Dominant Stems
When two trunks grow from the same spot, they often compete for space and light. This creates a weak point where the trunks join, increasing the chance of splitting during high winds.
3. Leaning Trunk
A tree that’s leaning more than usual, especially if the lean is sudden, may have root damage or shifting soil. This can signal instability and the potential for collapse.
4. Weak Branch Attachments
Branches that grow in tight, V-shaped angles are more prone to breaking. Over time, included bark can weaken these spots and make them more likely to fail.
5. Hollow or Decayed Areas
If the trunk or major limbs sound hollow when tapped, or show signs of rot or fungus, it’s likely the internal structure is compromised. These trees may look fine on the outside but can be unstable inside.

Disease and Pest Indicators
Not all tree damage comes from storms or age – sometimes the real threat is what’s happening inside or beneath the bark. Fungal infections, insect infestations, and bacterial diseases can slowly eat away at your tree’s health. The tricky part is that many of these issues start small and spread fast if left untreated. Knowing the early signs can help you catch a problem before it becomes widespread. In this section, we’ll go over common symptoms of disease and pest activity so you know what to look for and when to call in a pro.
1. Discolored or Spotted Leaves
Leaves that turn yellow, brown, or have strange spots during the growing season may point to fungal or bacterial infections. If only certain branches are affected, the issue may already be spreading internally.
2. Early Leaf Drop
If your tree sheds leaves well before fall, it’s a sign something’s wrong. Stress from pests, disease, or root problems often causes early defoliation.
3. Fungal Growth or Mushrooms at the Base
Mushrooms growing around the trunk or root zone usually signal decay inside the tree. This can weaken the structure and increase the risk of failure, especially during storms.
4. Holes or Sawdust Around the Trunk
Tiny round holes, sawdust piles, or trails of sap could mean wood-boring insects like beetles are attacking from the inside out. These pests are tough to spot but can do serious damage fast.
5. Unusual Swelling or Cankers
Bumps, sunken patches, or open sores on the bark (called cankers) often form when a tree is fighting off infection. These areas can split, crack, or ooze sap and should be checked right away.
Environmental Stress Factors
Even healthy trees can struggle when the environment around them changes. Drought, poor soil conditions, pollution, or construction damage can all put stress on your trees over time. These issues may not kill a tree right away, but they slowly weaken its defenses, making it more vulnerable to pests, disease, and structural failure. In this section, we’ll break down the most common environmental stressors that affect trees in residential areas and how to recognize when your tree might be under pressure.
1. Drought Stress
Lack of water over a long period can lead to wilting, browning leaves, and stunted growth. Even after rainfall returns, a tree may continue to decline if the roots have been damaged.
2. Soil Compaction
Heavy foot traffic, vehicles, or construction equipment can compact the soil around a tree. This reduces oxygen flow to the roots and makes it harder for the tree to take in water and nutrients.
3. Salt or Chemical Damage
Trees near roads, sidewalks, or driveways are often exposed to road salts or lawn chemicals. These substances can burn roots and leaves, causing yellowing, browning, or dieback.
4. Root Disturbance from Construction
Digging near trees for fences, patios, or utility lines can slice through roots and upset the tree’s support system. Damage may not show up right away but can lead to a slow decline.
