How To Spot Tree Hazards Before They Cause Damage

Trees add beauty, shade, and value to your property, but sometimes they can also pose a serious risk. A tree that looks healthy on the outside might be hiding decay, disease, or structural weakness. At Northland Tree Care, we often get called in after a storm, but many tree failures can be prevented with early intervention.

Here are 7 common signs that a tree may be dangerous and need attention from a qualified arborist in Whangārei or Northland.

1. Leaning Suddenly Or More Than Usual

All trees lean a little, but a sudden tilt, especially after a storm, can indicate root failure or trunk instability. If your tree wasn’t leaning last season and now it is, that’s a red flag.

2. Large Dead Branches (Deadwood)

Dead branches can fall without warning, even in calm weather. Trees shedding large limbs from the top (known as “sudden limb drop”) are particularly dangerous. Deadwood removal is one of the simplest ways to make your tree safer.

3. Cracks In The Trunk Or Main Branches

Long vertical cracks, deep splits, or visible wounds (inclusions) in the trunk may mean the tree is structurally unsound. Trees with double leaders are especially prone to splitting during high winds.

4. Mushrooms Or Fungus At The Base

Fungal growth near the base of a tree may indicate internal decay. If you spot mushrooms, shelf fungus, or soft, spongy bark, the root system could be compromised, even if the top looks healthy.

5. Exposed Roots Or Uplifted Soil

After heavy rain or wind, check the base of the tree. Is the ground lifting or cracking? Are roots suddenly exposed? These are signs the tree might be shifting in the soil and could topple.

6. Unbalanced Canopy Or Lopsided Growth

Trees that have grown unevenly, often because they’re reaching for light or have been damaged before, are more likely to break or fall. If one side is heavily weighted, professional pruning can help restore balance.

7. Previous Storm Damage

Trees that lost limbs or were partially split in past storms are more vulnerable the next time wild weather hits. A damaged tree might seem stable now but could fail without warning.

What Should You Do If You Spot These Signs?

Don’t take chances with a potentially hazardous tree. It’s always best to have a qualified arborist inspect it, especially before winter storms, strong winds, or major property projects.
