When a big storm is coming, most people start looking around the house. They bring chairs inside, check the gutters, and maybe move a few things out of the yard. Trees usually get a quick look too. If they are green and standing straight, they seem okay. But that is not always true. A tree can look healthy and still have problems that are hard to see. There could be rot inside the trunk. A large branch might have a small crack. Roots under the ground may be weak or damaged. These things can be easy to miss when you are just looking from your porch. A tree hazard assessment can help find some of these problems before severe weather arrives.
It does not mean every tree with a flaw is dangerous. Trees are not perfect, after all. But knowing what is happening before the wind starts blowing can give homeowners more time to deal with a problem.
Arbor Wise Tree Service helps homeowners look for these less obvious warning signs and understand what they may mean.

ToggleA Green Tree Is Not Always a Strong Tree
It is pretty easy to think green leaves mean a tree is healthy. Most of us probably look at trees that way.
And sometimes that is true.
The problem is that leaves only show part of what is happening. A tree can keep growing leaves even when part of the trunk has internal tree decay. A branch can look normal from the ground while its connection to the trunk is getting weaker.
These hidden tree defects matter more when bad weather comes.
Strong wind pushes and pulls on branches. The trunk bends a little. Roots have to hold everything in place, sometimes while the soil is soaked with rain.
A tree hazard assessment looks at more than leaves. The trunk, branches, roots, old wounds, cracks, and even the soil around the tree can provide useful clues.
No one can promise that a tree will never fail during a storm. Weather can be unpredictable. Still, finding a weak area early is usually better than discovering it when a branch is already on the roof.
Rot Can Hide Inside a Tree
Hidden tree rot is a strange problem because sometimes there is not much to see.
The outside of a trunk may still look solid. Meanwhile, decay can slowly develop inside the wood.
There may be clues, though.
Tree trunk cavities can be one of them. Mushrooms growing around the base may be another. Old wounds, missing bark, or areas that look unusually soft can also deserve a closer look.
An old pruning cut can sometimes become part of the problem too. A tree does not heal a wound exactly like people do. It grows around the damaged area and tries to contain it. Sometimes that works pretty well. Sometimes decay gets farther into the wood.
This is why one little hole does not tell the whole story.
During a tree hazard assessment, different signs are looked at together. The size of the cavity matters. So does its location, the amount of healthy wood around it, and what is near the tree.
A hollow-looking tree is not automatically going to fall. On the other hand, ignoring a large cavity because the leaves still look nice probably is not a great idea either.
Some Branch Connections Are Weaker Than They Look
Branches grow in all sorts of directions. Some attach to the trunk with wide, strong connections. Others grow very close together.
That can create weak tree branch unions.
One problem is called included bark in trees. This happens when bark gets squeezed between two stems as they grow. Instead of forming one strong connection, the stems can push against each other.
You may also see codominant tree trunks. This means two main stems are growing from about the same place.
Codominant trunks are not automatically dangerous. Plenty of trees have them for years. Still, certain connections can be weaker, especially when the stems are large and heavy.
Cracked tree branches can be even harder to notice when they are high up.
A crack may start small. Maybe it does not look like much. Then wind moves the branch back and forth for hours, and suddenly that little problem matters a lot more.
A pre-storm tree inspection can help spot these tree structural defects before the weather gets rough.

Dead Branches Can Hide in a Full Canopy
Dead branches are usually easy to notice when they are low.
High in a tree? Not so much.
Tree canopy deadwood can blend in with healthy branches, especially in a large tree with lots of leaves. From the ground, everything may look like one big green canopy.
If you look carefully, you might notice a branch without leaves. The bark may be peeling. Small twigs may be missing.
Sometimes you will not notice anything at all.
Deadwood can become dry and brittle over time. That can make it more likely to break, particularly during wind and heavy rain.
A tree hazard assessment can help determine whether deadwood is present and whether it actually creates a concern.
Location matters quite a bit here.
A small dead branch over an empty corner of the yard is different from a large dead limb hanging over the driveway where the family parks every night. They are both dead branches, but the possible result if they fall is not the same.
Do Not Forget About the Roots
People look up when they inspect trees.
That makes sense. The branches are up there.
But sometimes the bigger problem is under your feet.
Roots help hold a tree in the ground. When they become damaged, the tree may lose some of that support.
Root damage warning signs are not always obvious. Look for exposed or cut roots, changes in the soil, or areas where construction happened close to the tree.
Maybe a trench was dug for a pipe a few years ago. Perhaps heavy equipment drove over the root area during a home project. It happened, the project ended, and everyone forgot about it.
The tree did not necessarily forget.
Soil heaving around tree roots is another sign worth noticing. If the ground near the trunk begins lifting, cracking, or moving, especially after strong winds, the root plate may be shifting.
That deserves attention.
A tree can survive root damage for quite some time. This is what makes hidden tree damage a little confusing. The problem may have started years before anyone notices a change above the ground.
Pay Attention When Something Looks Different
Homeowners actually have one advantage when it comes to spotting tree problems.
They see the trees all the time.
You may not know the technical name for a problem, but you might notice that something changed.
Maybe a large branch seems lower than it was last month. A crack looks wider. One side of the canopy suddenly has fewer leaves. Or the ground near the trunk looks raised after a windy night.
Those little observations can be useful.
A tree hazard assessment considers changes like these when looking at tree failure risk. Fresh cracks, hanging limbs, cavities, dead sections, unusual leaning, and root movement can all provide information.
One sign might not mean very much by itself.
Several signs together? That can be different.
I think this is where homeowners sometimes get confused. They are looking for one giant warning sign that says, basically, “This tree is dangerous.”
Trees rarely make it that simple.
Check Trees Before the Storm Is on the Radar
A tree inspection before storm season is much easier than trying to deal with everything the day before severe weather arrives.
By then, people are rushing.
Tree services may already be busy. Homeowners are trying to prepare the house. The weather forecast keeps changing. There is just a lot happening at once.
Storm preparation for trees should ideally happen earlier.
A tree hazard assessment gives you time to learn what may need attention without having to make a rushed decision.
Maybe a dead branch needs pruning. Perhaps a damaged area should simply be watched. A tree with a serious structural problem might need more work.
Not every inspection ends with a big job.
Actually, sometimes the useful part is simply finding out that a strange-looking area is not as serious as you thought.
A tree inspection before storm conditions arrive is about reducing reasonable risks. It cannot make a yard completely storm-proof. Even strong, healthy trees can lose branches in extreme weather.
Look Again After Severe Weather
Once the storm passes, it is tempting to clean up the obvious mess and move on.
Trees may need another look.
A storm-damaged tree inspection can find changes that were not there before. Large branches may be cracked but still attached. A tree might lean differently. Roots may have shifted. Sometimes a broken branch gets stuck in another part of the canopy instead of falling all the way down.
That last one is especially easy to miss.
From the ground, the tree may look mostly fine. Then the branch falls days later when the weather is calm.
An arborist tree risk assessment can help look at both the condition of the tree and what is around it. A weak branch over a shed is one situation. The same branch over a walkway, bedroom, or driveway is another.
Risk is not only about whether something can break. It is also about what might happen if it does.

A Defect Does Not Always Mean Tree Removal
Finding a problem can make people nervous.
That is understandable. Nobody wants to hear that a huge tree next to the house has a defect.
But a defect does not automatically mean the tree has to come down.
Some problems can be handled with pruning. Others may need to be watched over time. Sometimes the safest choice may be removal, but that depends on the tree and the situation.
Mature trees naturally have scars, old pruning wounds, dead branches, cavities, and other imperfections. Trees spend decades outside in rain, wind, heat, and storms. They are going to look a little rough eventually.
The important question is whether a defect is affecting the tree’s structure enough to create a meaningful risk.
That is different from simply asking whether the tree looks perfect.
Take a Few Minutes to Look at Your Trees
Dangerous trees before storms do not always look dangerous.
That is probably the biggest thing to remember.
Walk around the yard once in a while and really look at the trees. Check the trunk from different sides. Look up into the canopy. Notice dead branches, cracks, cavities, leaning, exposed roots, or changes in the soil.
You do not need to diagnose the tree yourself.
If something looks different or you simply cannot tell what you are seeing, a professional inspection may help.
Arbor Wise Tree Service can perform a tree hazard assessment to look for structural concerns and warning signs that homeowners may not easily notice from the ground.
Storms will always bring some uncertainty. There is no way around that. But checking trees early can uncover problems while there is still time to think about what to do next, instead of trying to figure it out while the wind is already picking up.
