Got an Active Hazard? Skip Ahead.
If you're reading this in the middle of an active emergency, jump straight to the relevant guide.
The First 24 Hours
Whether the storm just hit or you woke up to damage, here's the right sequence — in priority order.
- 1
Account for everyone
People and pets first. If anyone is injured or trapped, call 911. If anyone is sleeping near visibly damaged areas of the house, move them now.
- 2
Check for downed lines and gas leaks
Stay 35 feet from any tree touching a wire — assume it's live. If you smell gas, evacuate and call the utility. Alliant Energy 1-800-862-6222, MGE 608-252-7222, We Energies 1-800-662-4797.
- 3
Photograph the original scene
Wide shots and close-ups of every damaged tree, every affected structure, and any branches on the ground near the trees. Insurance adjusters need this; do it before anyone moves anything.
- 4
Identify active vs. stable damage
Active = tree on a structure, against a wire, hung up in another tree, partially supported. Stable = tree fully on the ground, branches snapped off but tree still standing, surface damage to bark.
- 5
Call us for active hazards
(608) 751-4171, 24/7 during storm events. We dispatch within an hour for emergencies and document everything for your insurance claim.
- 6
Open an insurance claim for stable damage
Call your insurer within 24–48 hours. Provide photos and a brief summary. They'll assign an adjuster who will inspect within 1–2 weeks for non-emergency claims.
- 7
Schedule a post-storm inspection of intact trees
Trees that look fine after a storm may have hidden damage. Schedule an ISA Certified Arborist walk-through within 1–2 weeks of any major event — most failures we see are on trees that "survived" the original storm but failed weeks or months later.
Wisconsin Storm Types and Tree Damage
Different storms produce different damage. Recognizing the type helps predict where hidden damage may be hiding.
Summer Thunderstorms
May–September
Wind shear breaks branches at unions, twists trunks, and brings down weakened or hollow trees. Most common storm-damage cause across Southern Wisconsin. Often produces partial damage that's easy to underestimate — get an inspection if winds were over 50 mph.
Derecho Events
Rare, summer
Catastrophic straight-line wind events with sustained 75+ mph winds. The August 2020 derecho took out tens of thousands of trees from Iowa across Wisconsin. When one hits, expect 1–2 weeks of recovery wait time and prioritize active hazards over cleanup.
Ice Storms
Late fall through early spring
Ice load adds weight far beyond what trees evolved to carry. Multi-stemmed species (river birch, magnolia) and trees with weak unions split. Damage often appears days after the storm as ice cycles through freeze-thaw and weakens compromised wood further.
Heavy Wet Snow
Late fall, early spring
Worst when it falls on trees that haven't dropped leaves yet (October) or have just leafed out (April–May). Branch droop and split common on evergreens and recently-leafed hardwoods. The April 2018 Wisconsin storm caused damage we're still managing.
Lightning Strikes
Year-round, peak summer
Spiral or longitudinal trunk splits, often with bark blown off in a strip. Tree may appear healthy for weeks before delayed structural failure. Lightning-struck trees should always be assessed within days, not weeks. Tall isolated trees and oak species are highest risk.
Hail Damage
May–August
Bark damage, broken small branches, shredded foliage. Rarely produces trunk failures directly, but cumulative stress predisposes trees to fail in later storms. Common across Walworth and Jefferson counties during summer. Usually requires professional cleanup and follow-up plant health care.
Working With Your Insurance Company
Most storm-damage claims are covered. Here's the four-step process and where homeowners commonly leave money on the table.
Document
Photographs of original scene, damage list, and our written incident report from the make-safe visit if applicable.
Open a Claim
Call your insurer within 24–48 hours. They'll assign an adjuster who'll inspect within 1–2 weeks.
Get Estimates
We provide a written estimate aligned to insurer norms. You can request 2–3 estimates if you want; most adjusters expect this for larger claims.
Authorize and Bill
Once the claim is approved, we complete removal and cleanup. We bill the adjuster directly in many cases, or you pay and submit for reimbursement.

Insurance Claims Guide →Storm Response by City
We dispatch emergency crews from our Janesville headquarters and Madison area office across Southern Wisconsin. City-specific guides cover local response patterns and storm-history context.
Save the Tree, or Remove It?
Once the immediate hazard is handled, the decision becomes whether to preserve the tree or remove and replace. Cost, species, and damage pattern all factor in.
Likely Saveable
- •Branch torn off cleanly with intact branch collar
- •Partial trunk crack in otherwise healthy mature tree
- •Specimen tree with cabling-amenable structure
- •Minor canopy thinning from wind
Depends — Get Assessment
- •Major branch tear with bark stripping
- •Crack near a critical union
- •Lightning strike with delayed symptoms
- •Storm-vulnerable species with partial damage
Likely Removal
- •Root failure or visible heaving
- •Trunk crack through heartwood or full diameter
- •Multiple structural failures on one tree
- •Dead or declining tree before the storm hit
Cabling and bracing as an alternative
For partial cracks and weak unions on healthy trees, cabling and bracing can extend safe tree life by 10–30 years for a fraction of removal-plus-replacement cost.
Tree Cabling and Bracing Service →Preventing the Next Storm from Doing the Same
Most storm-damage emergencies we respond to were preventable with off-season work. Three programs that reduce next-storm risk:
Pre-Storm Hazard Assessment
An ISA Certified Arborist walks your property, identifies structurally compromised trees, and ranks them by failure risk. We provide a written report with options for each tree.
Arborist Services →Structural Pruning Programs
Annual or biennial pruning that removes deadwood, reduces wind load on weak unions, and corrects structural problems before they become failures. Cheapest insurance against storm damage.
Tree Trimming Services →Cabling and Bracing
Steel or synthetic cables that redistribute load across weak unions, plus through-trunk bracing for split-prone trees. Extends safe tree life by decades on the right candidates.
Cabling and Bracing →Storm Damage FAQs
What's the very first thing to do after a storm damages my trees?
Make sure people are safe, then assess what's active vs. stable. Active hazards (tree on a structure, on a vehicle, against a power line, hung up in another tree) need same-day professional response — call us at (608) 751-4171, 24/7 during storm events. Stable damage (snapped branches on the ground, partial trunk cracks on trees away from structures) can wait 24–72 hours for assessment. Photograph everything before you move anything; insurance adjusters need original-scene documentation.
Will my homeowners insurance cover tree damage from a storm?
Almost always, with caveats. Standard homeowners policies cover damage to your house, garage, fence, or other covered structure when a tree falls on them due to a covered peril (wind, hail, snow, ice). Most policies also cover the tree removal cost up to a sub-limit, typically $500–$1,000 per tree. Trees that fall but don't hit a covered structure are usually not reimbursed — most insurers consider that landscape damage rather than property damage. Comprehensive auto coverage handles trees that fall on vehicles. We work directly with adjusters and provide the documentation that supports your claim.
How quickly can you respond to storm damage in Southern Wisconsin?
For active emergencies (tree on a structure, downed lines, gas leaks), we typically arrive within 60–90 minutes of your call across Rock County, Dane County, Walworth County, and Jefferson County. We have a dedicated emergency crew on standby during named storm events. For non-active situations (damage is stable, no structural threat), we'll typically schedule you within 24–72 hours depending on storm scope. After the August 2020 Iowa-derecho event, our wait was about a week; in normal storm conditions it's same-day to 24 hours.
Should I save the damaged tree or remove it?
Depends on the damage pattern, the species, and the tree's overall health. Branches torn off cleanly often heal well — proper pruning of the wound and the tree recovers. Trunk splits can sometimes be saved with cabling and bracing if they're partial and the tree is otherwise healthy. Trees with root failure (visible heaving, exposed roots) almost always need removal — the structural support is gone. Storm-vulnerable species in poor health (silver maple, willow, Bradford pear) are usually better removed and replaced. Our cracked-trunk decision guide walks through each scenario.
What types of trees are most likely to fail in Wisconsin storms?
The species we see fail most often: silver maple (brittle wood, weak unions), willow (water-loving, often grows on saturated soil that fails first), Bradford pear (notorious for splitting at branch unions), cottonwood (massive but brittle), Lombardy poplar (short-lived and weak), and large trees with included bark or co-dominant stems regardless of species. Healthy oaks, hickories, and properly pruned maples tend to weather Wisconsin storms well. If you have any of the high-risk species near your house, proactive assessment before storm season is much cheaper than emergency removal during one.
How do I know if a tree that survived a storm is actually safe?
Visible damage (broken branches, missing bark) is the obvious part. The hidden damage is what matters — cracked unions, partial root failure, internal trunk splits, and lightning-strike damage that hasn't shown surface signs yet. After any major storm event, get a post-storm inspection from an ISA Certified Arborist. We look for cracks at branch unions, root heaving, fungal growth, lean changes, and species-specific failure indicators. Trees that survived the storm visibly may still fail in the next one if hidden damage isn't caught.
Does Wisconsin have many storm events that damage trees?
Yes — Wisconsin sits in the corridor that gets summer derechos, severe thunderstorms, ice storms, and heavy wet snow. Major events that produced widespread tree damage in recent years include the August 2020 Iowa derecho (extending into Rock and Dane counties), the April 2018 winter storm (heavy wet snow on early-leaf trees), the November 2019 ice storm across south-central Wisconsin, and dozens of severe summer thunderstorms each year. Average homeowner can expect 1–2 storm events per decade severe enough to require professional tree work, plus annual minor cleanup needs.
