Trees are valuable assets — they add beauty, shade, and property value. But sometimes a tree becomes more of a liability than an asset. Knowing when to remove a tree can prevent costly property damage, protect your family's safety, and even save neighboring trees from disease.
Here are the seven most important warning signs that a tree needs to be removed:
Significant Structural Damage or Decay
Large cavities, extensive rot, or structural cracks in the trunk or major limbs indicate serious structural compromise. While some decay is normal in older trees, extensive internal decay can cause sudden failure — particularly during storms or high winds. A tree that has lost more than 30% of its structural integrity should be evaluated for removal.
Dead or Dying Branches Throughout the Crown
A few dead branches are normal and can be pruned. But when more than 25-30% of the crown is dead or dying, the tree's overall health is severely compromised. Dead branches are also significantly more likely to fall, creating hazards for anyone below.
Leaning at an Unusual Angle
Trees naturally grow toward light and may lean slightly. But a sudden change in lean, or a lean greater than 15 degrees from vertical, indicates root failure or structural compromise. This is particularly concerning after storms or periods of heavy rain when soil is saturated.
Root Damage or Failure
Visible root damage, heaving soil around the base, or fungal growth (mushrooms) at the base of the tree are all signs of root problems. Roots provide structural support and nutrient uptake — when they fail, the entire tree is at risk. Root damage is often caused by construction, soil compaction, or disease.
Disease or Pest Infestation
Some tree diseases and pest infestations are treatable; others are not. Emerald Ash Borer, for example, is nearly always fatal to Ash trees once established. Dutch Elm Disease is similarly devastating. If you notice unusual bark patterns, oozing sap, discolored foliage, or insect activity, have the tree evaluated promptly.
Proximity to Structures or Power Lines
A healthy tree in an open field is very different from the same tree 10 feet from your home. Trees near structures require more careful management, and sometimes removal is the safest option — particularly if the tree is large, declining, or has a history of dropping branches.
Storm Damage
After a major storm, assess your trees carefully. Significant crown loss, major structural cracks, or uprooting may make a tree unsalvageable. Sometimes what looks like storm damage is actually the storm revealing pre-existing structural problems that made the tree vulnerable in the first place.
When in Doubt, Get a Professional Assessment
Tree risk assessment is not a DIY project. A tree that looks healthy from the ground may have significant internal decay that's only visible to a trained eye. Conversely, a tree that looks alarming may be perfectly stable with proper pruning.
At Gems Tree Services, we provide free on-site assessments. We'll give you an honest opinion — including whether a tree can be saved with trimming or whether removal is the right call. We don't recommend removal unless it's genuinely necessary.
