7 Warning Signs Your Tree Is a Hazard
7 Warning Signs Your Tree Is a Hazard – When to Call for Tree Removal in Iowa City
Don't Wait for Disaster to Strike
Trees are a cherished part of our landscapes in Iowa City, offering shade, beauty, and even boosting property value. But sometimes, what looks like a strong, majestic tree can hide dangerous weaknesses. Knowing the signs you need tree removal could prevent property damage—or even save a life.
This blog will guide you through the key indicators that a tree has become a hazard and why timely action through hazardous tree removal in Iowa City is critical.
1. Leaning Trees: A Subtle but Serious Signal
Some trees naturally lean, but if your tree is suddenly leaning or tilting more than usual, it could be unstable.
Watch for:
- Recent shifts in the soil near the base
- Exposed roots on one side
- New cracks in the trunk or soil around it
A leaning tree often indicates structural instability, and it could fall without warning—especially during a storm.
When to call: Immediately. This is one of the most urgent signs you need tree removal.
2. Cracks and Splits in the Trunk
Visible splits, cracks, or hollow areas in a tree's trunk can seriously compromise its strength.
Common signs:
- Deep vertical cracks in the bark
- Fungal growth near splits
- Insects or small animals nesting inside
Large cracks can indicate internal decay, making the tree unpredictable and dangerous.
When to call: As soon as visible damage is detected, especially if it’s near a structure or walkway.
3. Dead or Falling Branches
Dropping branches are more than a nuisance—they’re a red flag for health and safety.
Signs of a hazardous tree:
- Bare limbs during the growing season
- Branches that snap easily or fall without wind
- A large number of dead branches on the ground
Dead limbs are not just signs of decline—they can become lethal projectiles during storms.
When to call: If multiple large limbs are dead or falling, it’s time for hazardous tree removal in Iowa City.
4. Root Damage or Decay
Tree roots are the anchors and lifelines of a tree. When they’re compromised, the tree becomes a ticking time bomb.
Signs of root trouble:
- Mushrooms or fungal growth at the base
- Soil heaving or cracking around roots
- Nearby construction that may have cut or compacted roots
Root decay often goes unnoticed until it’s too late, so any visible sign should be taken seriously.
When to call: Immediately after spotting decay or construction disturbance.
5. Hollow Trunk or Internal Rot
A hollow tree might still look healthy on the outside, but the inside tells a different story.
Common indicators:
- Knocking on the trunk produces a hollow sound
- Cavities visible in the trunk
- Woodpecker activity (a sign of insect infestations)
A tree can’t support itself indefinitely if it’s rotting from within.
When to call: If more than 30% of the trunk is hollow, removal is usually necessary.
6. Disease and Pest Infestations
Diseases and pests weaken the tree and often spread to nearby vegetation.
Look for:
- Discolored leaves or early leaf drop
- Bark peeling or discolored sap
- Presence of beetles, caterpillars, or scale insects
Some diseases spread quickly and can kill a tree in months.
When to call: If pests or disease signs affect more than a single limb, get a professional inspection fast.
7. Proximity to Power Lines or Buildings
Even a healthy tree can become a hazard if it's growing too close to infrastructure.
Risk factors include:
- Branches touching or growing near power lines
- Roots disturbing sidewalks, driveways, or home foundations
- Trees hanging over roofs or garages
The liability of falling limbs or power outages is too high to ignore.
When to call: Right away—especially if branches are within 10 feet of utility lines.
