5 Signs Your Napa Property Needs Tree Inspection & Safety Corrections

Your trees bring tremendous value to your Napa property—shade, beauty, property value—but when left unchecked, they can also become liabilities. At Mike’s Tree Service, we help homeowners in Napa County identify risk factors early, avoid costly emergencies, and maintain a healthy, beautiful landscape.



Here are five key signs that mean you should schedule a tree inspection and likely corrective work soon.

1. Unusual Leaning or Root Uplift

2. Cracks, Splits or Cavities in the Trunk

Structural defects like large cracks, splits, or hollow sections inside a tree trunk mean internal decay might be at work. These conditions often go unnoticed until the tree fails. The right arborist will identify weak attachments, assess risk, and recommend trimming, bracing or removal.

3. Dead or Falling Large Branches

A few fallen twigs are normal—but large limbs dropping, especially repeatedly, is not. Dead major branches or limbs that snap during moderate winds indicate the tree’s health is compromised and the safety of your home, roof or guests may be at risk.

4. Mushrooms or Fungal Growth at the Base

Fungal growth such as mushrooms or conks at the trunk base usually signals internal wood decay or root damage. Because the visible part is only the surface, this kind of issue often requires professional intervention to evaluate the extent and decide what to do.

5. Canopy Thinning, Sparse Leaves or Sudden Leaf Drop

While seasonal leaf loss is expected, a tree showing thinning, early drop or discoloration in off-months may be suffering from disease, root damage or stress. Early detection and treatment can often save the tree—and prevent the need for full replacement.
