A tree on a structure lets water in with every rainfall — we remove, tarp and secure in one visit, 24/7
📞 CALL NOW: (800) 792-0212 🔍 Request Free InspectionWhen a storm-damaged tree strikes your Onalaska home, garage, or outbuilding, the clock starts immediately — and every minute of inaction compounds the damage. A punctured roof is not a one-time event; it becomes an open wound that absorbs every subsequent rainfall, turning a tree-removal job into a full-scale water damage restoration. Even a small penetration in your roofing system can allow dozens of gallons of water into your attic, insulation, and ceiling within a single storm. Wood rot, mold colonization, and structural softening can begin within 24 to 48 hours of the initial breach.
Beyond water intrusion, secondary collapse is a serious risk. A tree resting against a roof structure continues to shift as it settles, as winds continue, and as crew vibrations during any attempted DIY removal alter the load distribution. Damaged limbs that appear stable can drop without warning. Additionally, if the downed tree is near utility lines — a frequent situation in Onalaska's older residential neighborhoods along Sand Lake Road and King Street — approaching the scene before utility clearance can be fatal. Never assume a line is dead. We coordinate directly with the utility company before our crews engage.
Your homeowner's insurance policy has a mitigation duty clause: you are expected to take prompt, reasonable action to prevent further damage after a covered loss. Waiting days for removal can be used by adjusters to dispute coverage for water damage that accumulated post-event. Finally, a tree blocking your driveway or primary egress is a safety emergency — it prevents fire trucks and ambulances from reaching your home. Do not wait. Call Allied Emergency Services now at (800) 792-0212.
Onalaska is a thriving city of approximately 20,000 residents situated along the eastern bank of the Mississippi River at the confluence with the Black River, directly north of La Crosse in La Crosse County. The city's geography — nestled between the bluffs of the Coulee Region to the east and the broad Mississippi River floodplain to the west — creates a unique weather environment that channels severe storm systems through the area with remarkable regularity. Thunderstorm cells tracking northeast along the Mississippi River valley often intensify as they approach the Onalaska–La Crosse metropolitan area, producing damaging straight-line winds, large hail, and frequent lightning strikes that topple the area's abundant mature hardwood trees.
The residential neighborhoods of Onalaska range from the established tree-lined streets near Powell Drive and Riders Club Road in the central city to the newer developments along Lakeshore Drive near Lake Onalaska — one of the largest backwater lakes on the Upper Mississippi River. The Sand Lake Road corridor features densely planted mature silver maples and cottonwoods that are particularly vulnerable to wind damage. Near Onalaska Middle School and Luther High School, large campus trees can create significant hazards during severe storms. The City of Onalaska also maintains Perkin's Park, Strickland Park, and the Great River State Trail corridor, where storm debris frequently blocks public access and creates hazards for cyclists and pedestrians. Allied Emergency Services is experienced working across all of these areas — from tight residential lots near the bluffs to open lakeside properties with significant equipment access challenges.
Western Wisconsin experiences some of the most dynamic severe weather in the Midwest. Spring and early summer bring supercell thunderstorms capable of producing tornadoes, baseball-sized hail, and wind gusts exceeding 80 mph. Late summer derecho events — fast-moving lines of severe thunderstorms — have historically caused widespread tree damage across La Crosse County, bringing down thousands of trees in single events. Winter brings ice storms and heavy wet snow loads that snap even healthy trunks and major limbs. Our crews have responded to storm events across every season in this region and understand the specific tree species, soil conditions, and access challenges unique to Onalaska properties.
Comprehensive storm response — from the first call to final cleanup.
When severe weather drops a tree onto your Onalaska property, the situation requires more than a chainsaw — it requires trained technicians who understand structural loading, tension cuts, and controlled drop zones. Whether the tree has landed on your roof, collapsed onto a vehicle in the driveway, crushed a section of fence, or is simply blocking your primary access, Allied Emergency Services dispatches immediately with the equipment needed for safe, precise removal. We evaluate the full situation — root ball stability, lean direction, widow-makers in the canopy, and adjacent utility lines — before making the first cut.
A tree through a roof is one of the most time-critical property emergencies a homeowner faces. Allied Emergency Services provides a complete single-visit response that addresses both the tree and the resulting structural breach. After safely removing the tree — using rigging and cranes when needed to prevent the removal from worsening the structural damage — our crew immediately transitions to emergency weatherproofing. Heavy-duty polyethylene tarps are secured over the damaged roof area using wood furring strips and anchored to undamaged deck sections. Any broken windows, door frames, or wall openings are boarded with OSB panels. Your home is protected before we leave.
Not every tree emergency involves a completely fallen tree. Storm-damaged "hangers" — large limbs still partially attached to the trunk but suspended at dangerous angles over structures, vehicles, or public spaces — are among the most treacherous situations in arboriculture. A hanger can release without warning, and improper cuts create explosive kickback. Split trunks with co-dominant leaders are similarly unpredictable. Allied Emergency Services uses professional rigging systems, bucket trucks, and crane equipment to safely access, rig, and lower hazardous limbs regardless of their location. We also handle large canopy removal from trees adjacent to power lines, working in coordination with the utility company.
Emergency tree removal addresses the immediate crisis, but the aftermath — a large stump at grade level, scattered wood debris, and brush piles — presents its own hazards and headaches. Allied Emergency Services provides complete post-removal site restoration services. Our commercial stump grinders reduce stumps to below-grade wood chips that can be raked level and overseeded. All log sections, limbs, brush, and debris are loaded and hauled off-site. We leave your Onalaska property clean, safe, and ready for restoration landscaping. Stump grinding is particularly important before restoration crews arrive to repair structural damage, as surface obstructions complicate equipment access.
The Mississippi River valley is one of the most storm-active corridors in Wisconsin. Here is a look at the types of severe weather events that have historically driven emergency tree removal demand across the Onalaska region.
Spring is historically the most active severe weather season for La Crosse County. Warm moist air from the Gulf of Mexico clashes with cold fronts sweeping down from Canada, generating supercell thunderstorms capable of producing large hail, tornadoes, and straight-line winds exceeding 70 mph. The Coulee Region's bluff topography can accelerate wind speeds through valleys, channeling destructive gusts into residential areas of Onalaska with little warning. Spring is also when soil saturation from snowmelt and rain makes tree root systems more vulnerable — a healthy-appearing tree may topple under moderate wind loads when its roots are saturated and unable to anchor effectively against lateral forces.
Derecho events — fast-moving, long-lived wind storms associated with a line of severe thunderstorms — have historically swept through western Wisconsin and the La Crosse metro area multiple times per decade. These events can produce sustained winds of 60–80 mph or greater across a swath hundreds of miles wide, toppling thousands of trees in a single evening. Onalaska's mature urban forest, with its abundant large silver maples, box elders, and cottonwoods, is particularly vulnerable. Following major derecho events, allied has mobilized multiple crews simultaneously to address the surge in emergency calls from La Crosse County homeowners.
Even outside of major storm system events, Onalaska receives frequent intense afternoon and evening thunderstorms during the warm season. Heat and humidity build throughout the day, and convective storms fire rapidly, often producing localized damaging winds, downbursts, and microbursts that can topple trees in very limited geographic areas. A neighborhood on Sand Lake Road may experience a tree-toppling downburst while properties just blocks away see no damage at all. These isolated events are just as destructive to affected homeowners as widespread storm events.
Ice storms are a recurring threat in the La Crosse area, where freezing rain events can coat every exposed surface — including tree branches — with one-quarter inch to a full inch or more of ice. The weight of that ice on a mature tree's canopy can be measured in thousands of pounds, and major branch failures under ice load are common. Heavy wet snowfalls in late fall and early spring are similarly destructive, bending branches beyond their elastic limit and splitting co-dominant leaders. Many of Onalaska's older, established trees carry structural defects that are exposed only under the weight of an ice or snow load — and those failures often land directly on rooftops.
Trees do not follow a calendar. Allied Emergency Services maintains 24/7 year-round readiness for Onalaska emergency tree removal calls. Whether it is a June derecho at 2 AM or a January ice storm at noon, our crews are equipped for the conditions and ready to respond. We maintain seasonal equipment inventories appropriate for Wisconsin's full weather spectrum — from summer chainsaw operations to winter rigging on ice-covered surfaces.
Every year, homeowners are seriously injured or killed attempting to remove storm-damaged trees from their own property with chainsaws. Emergency tree removal after a storm is categorically different from routine tree trimming — and it is one of the most hazardous activities a homeowner can attempt without professional training, equipment, and experience.
The most dangerous aspect of storm-damaged tree work is stored energy in compressed and tensioned wood. When a large branch or trunk fails under storm loads, the wood fibers on the compressed side of the break do not simply split cleanly — they retain enormous spring energy that can be explosively released when a cut is made in the wrong location or sequence. A cut into the wrong face of a loaded limb can cause the saw bar to be violently pinched, or can cause the log to roll, kick, or spring toward the operator at speeds that allow no time for reaction. Professional arborists train specifically in tension-cut identification and sequencing — skills that cannot be learned from a YouTube video.
Trees that have fallen onto roofs present additional hazards beyond tension wood. The structure itself becomes part of the load-bearing system, and removing sections of the tree in the wrong order can cause sudden shifts in the remaining load — potentially pulling roof decking, rafters, or fascia boards free, or causing a partially supported roof section to collapse. Allied Emergency Services uses rigging systems — ropes, blocks, and friction devices — to control exactly where each cut section goes as it is removed, preventing secondary structural damage and protecting crew members below.
Ladder work on a compromised roof structure is an extreme hazard. Many homeowners have fallen through weakened roof sections attempting to assess or address storm damage before professional help arrives. Our crews work from bucket trucks, cranes, and aerial lifts that keep them off compromised surfaces entirely when possible.
When trees are near utility lines — a common situation in Onalaska's established neighborhoods — the risks multiply dramatically. A chain saw touching a downed or sagging line, or a cut log section swinging into a line, can result in electrocution or fire. We coordinate with Xcel Energy and other utilities before our crews work anywhere near energized infrastructure.
Professional emergency tree removal also includes insurance-grade documentation. Our crews photograph the scene upon arrival, document the tree species and approximate dimensions, photograph all structural damage in detail, and create a written record of the event and work performed. This documentation is essential for your insurance repair claim. A properly documented emergency response protects you from coverage disputes and provides the adjuster with the evidence needed to process your claim efficiently.
Finally, the one-visit tarp-and-board-up handoff that Allied Emergency Services provides is only possible when tree removal and weatherproofing are performed by the same trained crew. That seamless transition from tree extraction to structural protection is what prevents a bad night from becoming months of ongoing water damage and mold remediation.
Allied Emergency Services is your restoration contractor from first call through final walkthrough. Here is how the process works.
The moment you call (800) 792-0212, we dispatch. Our priority on arrival is life safety — confirming no one is trapped, assessing utility hazards, and establishing a safe work perimeter. We then move immediately to tree removal and structural stabilization: extracting the tree, installing emergency roof tarps over all breach points, and boarding up compromised windows and openings. Our goal is to have your home weatherproofed before we leave the site — regardless of what time of day or night we arrive.
After stabilization, our crew conducts a systematic documentation of all damage. This includes high-resolution photography of the tree impact zone, all structural breaches, interior water intrusion evidence, and adjacent property damage. We document the tree dimensions, species, and point of failure. Measurements of all damaged structural elements are recorded. This documentation package is provided to you in a format designed to support your insurance repair process. Thorough documentation at the time of the event — before weather, cleanup, or time alters the scene — is essential. An underdocumented claim is a vulnerable claim.
Allied Emergency Services works alongside your insurance process as your licensed restoration contractor. We provide your insurer with our documentation and written scope of repair. We communicate directly with your adjuster to ensure that all storm-related damage is included in the repair scope and that our restoration plan aligns with the covered loss. Our role is to perform the restoration work — your insurer determines coverage under your policy. We do not adjust, negotiate, or settle insurance claims on your behalf. We repair what the storm damaged, completely and correctly.
Once the repair scope is established, Allied Emergency Services performs the full structural restoration of your Onalaska home. This includes roofing repair or replacement, structural framing repair, sheathing replacement, exterior siding repair, window and door replacement, and interior drywall and insulation restoration. We are a full-service restoration contractor — not a referral service. Our crews perform the work under proper permits where required, using materials that match existing systems. Every repair is performed to manufacturer specifications and applicable Wisconsin building codes.
Before we consider a job complete, we walk through every repaired area with you. You verify that all damage has been addressed to your satisfaction, that the workmanship meets your expectations, and that the site is clean and free of debris. We provide you with all warranty documentation, permit final inspection reports, and a complete record of work performed. Our commitment to Onalaska homeowners does not end when the last nail is driven — it ends when you are completely satisfied and your home is fully restored to pre-storm condition.
Reviews represent typical customer experiences.
We had a massive silver maple come down during a derecho and it went straight through our garage roof on Lakeshore Drive. I called Allied at midnight and they were on site before 1 AM. By 3 AM the tree was out, the roof was tarped, and the crew had cleaned up the driveway so my wife could get her car out in the morning. I honestly could not believe how fast and professional they were in the middle of the night. The documentation they provided made our insurance process go smoothly.
A huge cottonwood split right down the middle during a spring thunderstorm and one half landed on our back porch and went partway through the sunroom roof. The Allied crew came out same evening, used a crane to lift the trunk section off without destroying the remaining porch structure, and had tarps up and the opening boarded before it rained again that night. They were incredibly careful about not making the structural damage worse during removal — you could tell they knew exactly what they were doing. Highly recommend for anyone in the Onalaska area.
After an ice storm in February, we had three large limbs hanging over our house — completely terrifying. Allied came out within the hour, assessed all three, and used their bucket truck to safely remove them without touching the roof or the power line nearby. They coordinated with the utility company for one of the limbs that was draped over the line — something I would never have known how to handle. The crew chief explained every step before they did it. I felt completely informed and safe throughout the whole process. Worth every penny for the peace of mind alone.
From your first call to a fully secured, documented property — here is exactly what happens when you call Allied Emergency Services in Onalaska.
Call (800) 792-0212 any time of day or night. A live dispatcher answers immediately — not voicemail, not an answering service. We gather your address, a brief description of the situation, and any known utility or safety hazards. Our dispatcher immediately contacts the closest available crew and confirms your estimated arrival time. For active structural breaches or utility hazards, you are assigned Priority 1 dispatch status.
Our crew arrives on-site with the equipment pre-staged for the described situation. The crew chief introduces themselves, does a full scene walk, confirms safety perimeter, checks for utility hazards, and communicates the removal plan to you before any work begins. We do not start cutting until you understand the approach and any relevant risks are addressed. For scenes involving downed or adjacent power lines, we confirm utility clearance before crew members approach the tree.
Using professional rigging, cranes, bucket trucks, and properly sequenced cuts, we safely remove the tree from your structure or property. Every cut is deliberate and controlled. Heavy sections are rigged and lowered — not dropped — to prevent secondary damage to roofs, walls, vehicles, and landscaping. Our crew communicates continuously throughout the removal process. Once the tree is clear, we conduct a post-removal assessment to identify any remaining hazards — widow-makers, cracked limbs, compromised sections of canopy that pose ongoing risk.
Immediately after tree removal, if any structural breach exists, our crew installs emergency weatherproofing. Heavy-duty polyethylene tarps are laid over all damaged roof sections and anchored using wood furring strips nailed to the roof deck — not just thrown over the peak. Broken windows, door openings, and wall breaches are covered with OSB panels secured firmly. The goal is to make your home as watertight as possible before the next rainfall. We document all weatherproofing measures installed with photographs.
A thorough photographic and written damage documentation is completed before we leave the site. All debris — logs, brush, chips, and material — is loaded and removed. Your driveway is cleared. Your site is left clean and safe. You receive a summary of work performed, and our team coordinates next steps for the full structural restoration of your home. You have a single point of contact — Allied Emergency Services — for everything from tree removal through final restoration completion.
Our team responds within 1 hour — don't let damage get worse.
