Before You Cut: What to Do With a Storm-Damaged Tree

The morning after a big storm sounds the same on every block. Chainsaws. Somebody’s dad is already out there in a T-shirt and safety glasses, cutting limbs into pieces that will fit in the yard waste bin.

It’s a good instinct, mostly. You want the mess gone. But a hurt tree is one of the more dangerous things in the yard right after a storm, and it’s also one of the easiest things to lose for no real reason.

So slow down for a day.

Stay clear first

Limbs can hang up in a canopy for days and then just let go. One that’s pinned under another branch is loaded like a spring, and it can whip back when you cut it. If anything is touching a power line, back away and call the utility. That one isn’t a judgment call.

Plenty of damaged trees pull through

Trees are tougher than they look the morning after. A few questions sort out the ones worth keeping.

Was it healthy before? A strong maple that dropped a couple of big limbs usually comes back fine. A tree that was already thinning on top is a different story.

Did the trunk split? Lost branches you can live with. A crack running down the main trunk is usually a much bigger problem.

How much of the crown is left? Losing a few limbs is one thing. Being stripped down to stubs is another.

Is it leaning more than it used to? Watch for soil heaved up on one side of the base. That can mean the roots let go.

Oaks need a little extra care here in Minnesota. The University of Minnesota Extension puts oak wilt risk at its highest from April through July, and fresh wounds draw in the beetles that carry it. If a storm tears an oak limb during that stretch, paint over the wound right away with latex paint or shellac. Even a cheap can from the garage works.

And skip “topping,” which is cutting the branches back to stubs so the tree looks even. It weakens the tree. The new shoots that grow back tend to snap in the next storm.

When the tree went through the roof

Sometimes the tree is honestly the easy part. A limb comes through the shingles and now there’s an open hole, soaked insulation and a ceiling that’s starting to sag. That half of the job belongs to a Minnesota storm restoration contractor, not the tree crew. They cover the roof first so the rain stops getting in. The framing, drywall and paint come later, once things are dry.

It helps to keep the two jobs straight in your head. One crew takes the tree away. Another fixes the house. Get photos of all of it before either one starts, including where the trunk landed.

Who should look at the tree

For any tree you’re hoping to save, get a trained eye on it. The International Society of Arboriculture keeps a directory for finding and verifying ISA-credentialed arborists, so you can check a credential before anyone climbs. ISA says certification shows a person has at least the baseline knowledge and skill for the work their credential covers.

That check matters more after a storm than any other time, because that’s when the door knockers show up. Be careful with anyone who wants a signature right now, asks for cash up front or swears insurance will cover every dollar. Get the estimate in writing. Ask for proof of liability insurance and workers’ comp, too, because an uninsured worker who gets hurt on your property can turn into your problem.

A good arborist will look at the trees that seem fine, too. The big one by the garage might have a crack you can’t see from the ground.

That tree took decades to get that big. Giving it two days before the saw comes out is a pretty fair trade.
