How to Tell If a Tree Needs to Be Removed — A Lancaster PA Homeowner's Guide

In Lancaster County, I get called in to remove trees in two situations: when homeowners planned ahead and wanted a professional assessment, and when a tree already fell. The second call is always worse — more expensive, more stressful, sometimes with property damage already done. Here's how to catch the warning signs before you're in crisis mode.

Dead or Severely Declining Wood

The clearest sign a tree needs to come down is significant dead wood in the crown. Some dead branches are normal — trees drop limbs naturally. But when you see large sections of the canopy with no leaves during growing season, dead branches that are dry and brittle throughout, or bark falling off in large sheets, the tree is in serious decline.

Do the scratch test: use your thumbnail or a knife to scratch through a small patch of bark on several branches. Live tissue underneath is green or white and slightly moist. Dead tissue is brown, dry, and crumbles. If 50% or more of the branches you test are dead, the tree needs attention — either aggressive care or removal.

Structural Defects at the Base or Trunk

Problems at the base are the most dangerous. Look for:

• Cracks or splits in the trunk. Especially cracks that run vertically or that open and close with wind — those indicate structural failure.
• Fungal growth at the base or on the root collar. Mushrooms or shelf fungi growing at the base of a tree indicate significant internal wood decay. The tree may look healthy above ground while the structural support is rotting beneath.
• Heaving soil near the base. If the ground near the base of the tree is raised or cracked, the root plate is lifting — meaning the tree is losing its anchor.
• Exposed or severed roots. Construction damage, drought, or soil compaction can kill the structural roots a tree depends on for stability.

These base defects are what cause trees to fall without warning. A tree can look full and healthy from the crown while its structural support is almost entirely compromised. See our tree removal and assessment services for how we evaluate these situations.

Leaning — The Kind That Matters

Not every lean is dangerous. Trees that have grown with a slight lean toward light are generally stable — that's just how they grew. The lean that matters is a recent change: a tree that stood straight two years ago and now has a noticeable lean, especially toward your house or the street.

If you notice a new lean, check the base immediately. Look for soil disturbance, exposed roots, and whether the lean increased after a recent storm. A recently developed lean with any soil movement at the base is an emergency — call a tree professional that day, not next week.

Location Risk — When Healthy Trees Still Need to Come Down

Sometimes the tree itself is fine but its location isn't. Trees growing into power lines, trees that overhang a house (especially with large heavy limbs), trees planted too close to foundations — these create ongoing risk regardless of tree health.

In Lancaster County, we also see a lot of silver maples and Bradford pears — fast-growing species with weak wood that split easily in ice storms and high winds. If you have one of these species over your home, having it assessed before winter is smart planning. A clean removal now costs far less than emergency removal after a major limb comes through your roof.

When to Call a Pro vs. DIY

Small trees in open areas, away from structures and utilities — some homeowners handle these themselves with proper equipment. Anything that requires climbing, anything near power lines, anything within falling distance of a structure — call a licensed, insured tree company. The cost of a professional removal is a fraction of the cost of what a fallen tree does to a house.
