An open roof soaks insulation, drywall and framing with every storm — we tarp and secure it today, 24/7
When a storm peels back shingles, a falling branch punches through decking, or high winds lift a section of your roof, the clock starts immediately — and the damage compounds with every passing hour. The moment your roof is breached, the interior of your home becomes vulnerable to the next weather event, whether that is a passing afternoon thunderstorm or the heavy overnight rains so common along the La Crosse River valley corridor where Onalaska sits.
Within the first rainfall after a roof opening, water penetrates the underlayment and begins soaking the insulation batts in your attic space. Wet insulation loses its R-value almost immediately and becomes a sponge that holds moisture against your roof sheathing, accelerating rot and delamination of the plywood or OSB decking. Once that moisture migrates downward, it reaches your ceiling drywall — and a saturated ceiling can fail suddenly, creating a dangerous collapse hazard and destroying flooring, furniture, and personal property below.
Within 24 to 48 hours of moisture intrusion into wall cavities and ceiling spaces, mold colonies begin to establish themselves. In Wisconsin's warm summer conditions, mold can spread aggressively through insulation and framing within days, transforming what began as a roof repair into a much larger and more expensive remediation project. Electrical fixtures and wiring in the ceiling are also at risk — water reaching electrical boxes creates shock and fire hazards that require immediate attention from licensed electricians in addition to your roofing contractor.
From an insurance standpoint, your policy's duty-to-mitigate clause requires you to take reasonable steps to prevent further damage after a covered loss. An uncovered roof opening that allows continued water intrusion into your Onalaska home can give your insurance carrier grounds to dispute the portion of damage that occurred after the initial event — damage they could argue was preventable. Professional emergency tarping creates a documented record that you fulfilled your mitigation obligation. Do not wait. Call Allied Emergency Services at (800) 792-0212 right now.
Onalaska is a city of approximately 20,000 residents nestled between the Mississippi River bluffs and the expansive backwaters of Lake Onalaska, a widening of the Mississippi that defines the western edge of the community. This geography is beautiful, but it also shapes the severe weather that Onalaska homeowners face year after year. Warm, moist air masses moving northward from the Gulf of Mexico collide with colder Canadian air along the coulee country ridgelines, producing powerful thunderstorm lines that track through La Crosse County with regularity from late spring through early fall.
The neighborhoods of Onalaska are diverse in housing age and construction type. The older residential areas near the historic downtown and along Sand Lake Road feature homes built in the 1950s through 1970s with aging roof systems that are particularly vulnerable to hail and wind damage. Newer developments in the northern and eastern sections of the city — off Quincy Street, along the Highway 16 corridor near the Onalaska Center for Commerce and Industry, and in the newer subdivisions near Oak Grove School — feature more modern construction but are equally exposed to the severe convective storms that move through the region. The lakefront and bluff-adjacent properties near George Poeppel Memorial Park and Veteran's Memorial Park face elevated wind exposure due to their topographic positions.
Onalaska sits within La Crosse County, Wisconsin's storm corridor. The Mississippi River valley creates a natural channel for storm systems, and properties in communities like Onalaska, Holmen, and West Salem regularly experience wind gusts exceeding 60 miles per hour during summer thunderstorm events. Hailstorms capable of producing golf-ball-sized hail have struck the La Crosse metro area multiple times in recent years, leaving thousands of homes with damaged or destroyed roofing systems. Allied Emergency Services maintains coverage for all of La Crosse County and can reach Onalaska properties quickly via Highway 53 and the Interstate 90 corridor.
Comprehensive emergency protection for every type of storm roof damage
Onalaska's position along the Mississippi River valley makes it a frequent target for powerful line storms and supercell thunderstorms that produce straight-line winds capable of stripping entire sections of roofing from residential and commercial structures. When wind peels back shingles, lifts decking, or tears away ridge cap and flashing, the underlying roof structure is exposed to immediate weather intrusion. Our wind damage tarping service covers missing shingles, lifted or missing sections of decking, blown-off ridge caps, and any structural openings produced by extreme wind events. We assess the full extent of wind damage before installation, ensuring that our tarp covers not just the obvious breach but all compromised areas that could allow water entry.
Severe hailstorms in the La Crosse County region can deposit hailstones large enough to puncture asphalt shingles, crack tile roofing, and dent or perforate metal roofing systems. What makes hail damage particularly deceptive is that much of the worst damage is not immediately visible to an untrained observer. Hail impacts bruise the asphalt mat beneath shingle granules, cracking the waterproofing layer while leaving the shingle surface appearing relatively intact. These bruise points become water infiltration channels with the next rain event. Allied's hail damage assessment and cover service combines professional inspection of all roof surfaces with thorough photographic documentation of every hail strike, bruise point, and granule loss zone. We then install protective covering over all affected areas, creating a timestamped record that is invaluable for insurance claim purposes.
Onalaska's beautiful canopy of mature oaks, maples, and cottonwoods along its residential streets and near its parks and waterways can become projectiles during severe storms. When a large limb or entire tree falls on a home, the result is typically a complex emergency involving both structural damage and immediate weather exposure. Tree-strike roof damage presents unique challenges: the fallen debris must be safely managed before tarping can begin, the structural integrity of the damaged roof framing must be assessed, and the tarp installation must be coordinated in a way that accounts for the weight and position of any debris still resting on the structure. Allied Emergency Services has extensive experience managing tree-strike events, including coordination with tree removal services and temporary structural stabilization of compromised framing members before tarp installation.
Emergency tarping is the first chapter of the restoration story, not the ending. Allied Emergency Services provides a seamless transition from emergency protective measures to permanent, professionally executed roof repair or replacement. This continuity matters enormously: when the same company that documented the initial damage also performs the repairs, the scope documentation is consistent, the insurance adjuster's questions can be answered with firsthand knowledge, and there is no gap in accountability. Our tarp-to-repair transition service includes comprehensive pre-repair damage assessment that captures all storm-related issues — not just what is visible from the ground — coordinated scheduling with your insurance adjuster, a detailed written scope of repair, and execution by our licensed roofing and restoration crews. We carry your property from crisis to completion.
The Driftless Area and Mississippi River valley create some of Wisconsin's most active severe weather corridors — here is what Onalaska homeowners face.
The transition from winter to spring in the upper Mississippi River valley is marked by some of the most energetic severe weather of the year. As the jet stream retreats northward and Gulf moisture begins pushing into the upper Midwest, La Crosse County becomes increasingly vulnerable to supercell thunderstorms capable of producing large hail, damaging straight-line winds, and occasional tornadoes. Hailstorms during this window have historically produced stones ranging from pea-sized to golf-ball-sized, with the larger events capable of causing catastrophic shingle damage across entire Onalaska neighborhoods. Homeowners who have not had their roofs inspected following prior hail seasons may discover that accumulated damage has left them especially vulnerable.
July and August represent the peak of severe weather activity for Onalaska and the broader La Crosse metro area. Heat and humidity build during the day, and by late afternoon and evening, powerful storm cells develop along the coulee country ridgelines to the east and northwest. Derecho events — long-lived, fast-moving storm systems producing widespread wind damage across hundreds of miles — have struck the western Wisconsin region multiple times in recent years, leaving trails of damaged roofing across communities from La Crosse County northward into Trempealeau and Buffalo counties. These high-wind events are particularly damaging to older roofing systems and to homes with tall mature trees in close proximity. The combination of wind-stripped shingles and fallen trees creates a complex emergency roofing situation that requires immediate professional response.
As summer transitions toward fall, Onalaska frequently experiences a secondary pulse of severe weather activity driven by the collision of advancing cold fronts with lingering warm, moist air masses along the Mississippi River corridor. These transitional storms can be particularly intense, producing heavy rainfall rates that overwhelm gutters and flashing on marginally damaged roofs and pushing water into the attic spaces of homes that sustained hail or wind damage earlier in the season. September storms have historically produced significant flash flooding in low-lying areas near Lake Onalaska and along the La Crosse River, compounding storm damage with water damage. Homeowners who wait to have roof damage repaired after spring and summer events often face compounded damage from these fall systems.
Onalaska's winter climate brings its own set of roofing challenges. The city's position in the snow belt of western Wisconsin means significant snowfall accumulation is common, with some winters bringing well over 50 inches of total snowfall. Heavy snow loads on roofs already compromised by summer storm damage can accelerate structural failure. Ice dam formation along the eaves — a frequent occurrence when warm interior air escapes through attic insulation and melts snow that then refreezes at the cold eave overhang — can force water under shingle courses and into the wall and ceiling cavities. Homes that sustained hail or wind damage and were not properly repaired entering winter are at serious risk of progressive damage through the freeze-thaw cycles of the Wisconsin winter season.
After a major storm rolls through Onalaska, the impulse to climb a ladder and throw a tarp over the damaged section is understandable. You want to protect your home, and hardware stores typically sell blue poly tarps at accessible prices. But professional roof tarping and DIY roof tarping are not the same activity — and the difference can mean the difference between a manageable insurance claim and a denied one, between a safe roofline and a trip to the emergency room.
The danger begins the moment you put a ladder against the side of a storm-damaged house. Post-storm roofs are wet. Algae-covered shingles that were slippery before the storm are now even more so. Damaged sections of decking may be structurally unsound in ways that are invisible from below — a roof that appears to be intact may have hidden sheathing failures that will give way under a person's weight without any warning. Nationwide injury data consistently shows that post-storm ladder and roof falls spike dramatically in the hours and days following major weather events, as homeowners attempt emergency repairs before professional help arrives. The risk is real, and the injuries are serious.
Beyond safety, proper tarping technique matters enormously. A professionally installed emergency tarp uses commercial-grade polyethylene sheeting rated for the specific weather conditions expected. It is anchored using ballast boards threaded under the ridgeline, weighted down on the low-slope sections, and fastened in a manner that does not create new penetration points in the remaining sound roofing material. Consumer-grade tarps improperly fastened with nails driven through the tarp material will leak at every fastener point and will frequently fail within days when subjected to wind. A failed DIY tarp that allows continued water intrusion can give your insurance carrier grounds to attribute post-tarp damage to inadequate mitigation — complicating or reducing your claim.
Finally, professional tarping includes professional documentation. Our crews photograph the damage from multiple angles, note the dimensions and location of all breaches, and document the condition of adjacent roof areas that may have sustained secondary damage. This photographic and written record becomes a critical part of your insurance claim file — a record that a DIY tarp job cannot produce, because no untrained homeowner can document what they cannot safely access or identify.

The moment you call, we dispatch. Our target response time for Onalaska properties is one hour from your call. When our crew arrives, the first priority is securing your property and preventing further water intrusion. We assess the full extent of the damage, identify any structural hazards, and install professional-grade emergency tarping to stop the bleeding. We also photograph everything before we touch it — the pre-tarp condition is the foundation of your insurance claim. Emergency response is available 24 hours a day, 365 days a year, including holidays and overnight hours. A storm does not wait for business hours, and neither do we.
After stabilization, we conduct a systematic inspection of all damaged areas — not just the most visible damage, but all adjacent and secondary damage that a major storm event can cause. Hail damage, for example, often affects not just the roof but also gutters, siding, window screens, air conditioning units, and exterior woodwork. Wind damage can cause fascia, soffit, and flashing failures in areas away from the primary breach. We capture all of this with photographs, written descriptions, and dimensional measurements that give your insurance adjuster a complete picture of the storm's impact on your Onalaska property. Thorough documentation means fewer supplemental negotiations and a faster path to approved repairs.
Once your home is stabilized and damage is documented, we work alongside your insurance process to support an accurate and complete claim. We provide your insurance carrier with our detailed documentation package and make ourselves available to answer technical questions about the scope of damage. We can coordinate scheduling with your adjuster's on-site inspection and ensure that our crew's assessment is available for comparison with the adjuster's findings. If there are discrepancies between the adjuster's scope and the damage we observed, we communicate that clearly and factually, using our documentation as the basis for discussion. We are restoration contractors — we document damage and perform repairs. We do not adjust claims, negotiate claim values, or act as public adjusters.
With insurance coordination underway and an approved scope of repair established, our licensed roofing and restoration teams execute the permanent repairs to your Onalaska home. Depending on the extent of damage, this may involve partial shingle replacement over a specific area, full roof replacement with new underlayment and ice-and-water shield, decking repair or replacement, fascia and soffit restoration, siding repair or replacement, and interior work including drywall, insulation, painting, and flooring. We use materials that meet or exceed manufacturer specifications and local building code requirements, and all work is performed by our credentialed crews — not subcontractors of unknown qualification. Permits are pulled where required, and all work is completed to a final inspectable standard.
We do not consider a job complete until you do. When restoration work is finished on your Onalaska property, we conduct a thorough final walkthrough with you, the homeowner, reviewing every area of the repair and confirming that the work meets the agreed scope and your quality expectations. Any items that need attention are addressed before we close the job. We provide you with copies of all documentation, including the pre-repair damage photos, the repair scope, material data sheets, and permit inspection results where applicable. Our goal is a fully restored home and a homeowner who would confidently recommend Allied Emergency Services to a neighbor who faces the same storm damage situation in the future.
Reviews represent typical customer experiences.
"A line of storms came through around midnight and tore a section of shingles off the back of our house near the Lake Onalaska side of town. I called Allied at 1 AM and they had a crew at our house by 2:15. They got up on the roof in the dark with proper lighting, covered the whole damaged section, and had the entire thing documented before they left. Our adjuster was impressed with the photos. I cannot recommend these guys enough for emergency situations."
"We had a big oak come down across the peak of our roof during the August storms. Allied came out, coordinated with the tree service, and got the opening covered before the next round of rain came through. They walked us through exactly what happened structurally and what the repair would look like. Professional crew, honest communication, and the tarp held through three more rain events while we waited for the insurance adjuster. Couldn't have asked for better service."
"The hailstorm that hit our neighborhood in June looked minor until Allied did their inspection. They found bruising and granule loss on two-thirds of the roof that we would never have caught ourselves. They documented everything with photos and helped us understand what our insurance would need to see. The tarp they installed stayed put through a windy July. When the insurance came through, Allied did the full replacement. Start to finish, they handled everything right."
Allied Emergency Services targets a one-hour response time for Onalaska properties. Our crews access the area via Highway 53 and the Interstate 90 corridor, allowing rapid arrival to all Onalaska neighborhoods whether you are near Lake Onalaska, downtown, or in the newer developments on the east side of the city. We are available 24/7, including overnight and on holidays.
A commercial-grade polyethylene tarp, properly installed with ballast boards and perimeter anchoring, will typically remain weatherproof for 30 to 90 days in Wisconsin conditions. This window is sufficient for insurance adjuster visits, claim processing, and repair scheduling in most situations. Consumer-grade tarps without proper anchoring frequently fail within days, especially in the wind-exposed locations common in Onalaska's riverine geography.
In most cases, yes. Standard homeowners insurance policies treat professional emergency tarping as a mitigation expense and cover it as part of the covered loss. Our detailed documentation supports your claim submission. Always report the loss to your carrier promptly and document the damage before any protective measures are taken. Allied Emergency Services is a licensed restoration contractor, not an insurance adjuster — we support your claim process but do not manage or negotiate claims on your behalf.
DIY roof tarping after storm damage is one of the most dangerous home repair activities a homeowner can attempt. Post-storm roofs are wet, potentially structurally compromised, and very different environments from a dry-day roofing project. Injuries and fatalities from post-storm ladder and roof falls are documented every storm season. Beyond safety, improperly anchored tarps fail quickly and can complicate insurance claims. Call a licensed professional — it is the safe choice and the smart claim choice.
Allied Emergency Services provides full tarp-to-repair transition as a single, continuous service. After the emergency tarp is in place and documented, we coordinate your insurance adjuster inspection, provide our damage documentation package to support the claim, and upon claim approval, execute the permanent repairs with our licensed crews. You do not need to find a separate roofing contractor — we handle everything from emergency response through final walkthrough.
Call (800) 792-0212 any hour of the day or night. A real person answers — not a voicemail. Describe what happened and your address in Onalaska, and we dispatch immediately. While you wait, stay out of rooms directly below the damaged area.
Within minutes of your call, an Allied crew is en route to your Onalaska property. Our target arrival time is one hour from call. Crew members carry all materials and equipment needed for emergency tarping, structural assessment, and documentation in a single visit.
On arrival, our crew photographs all damage before touching anything. This pre-intervention record is critical for insurance purposes. We assess structural integrity, identify all breach points, and note any hazards that need to be addressed before tarping begins.
