A tree on a structure lets water in with every rainfall — we remove, tarp and secure in one visit, 24/7
When a tree falls on a structure in Oak Brook — whether it's your roof, your garage, your fence line, or a vehicle in the driveway — the clock starts immediately. The most urgent danger most homeowners underestimate is water intrusion. A punctured roof deck or cracked decking boards allow rainwater to pour directly into your attic, insulation, and ceiling drywall with every rainfall. In the greater Chicagoland area, where summer pop-up storms can follow one after another within hours, a single overnight rain event can turn a manageable tree-removal situation into a catastrophic mold, structural, and interior damage claim.
Beyond water, there is the issue of secondary collapse risk. Storm-damaged trees that appear stable can shift dramatically as the wood dries, as root plates release tension, or as secondary wind gusts move the hanging debris. A limb that seems lodged securely against a gutter can become a falling missile with the next gust. Loaded tension in split trunks is particularly dangerous — what looks like a stable leaner can snap violently without warning.
Never approach downed power lines. If the fallen tree has taken down any utility lines, treat the entire area as energized and keep everyone — family, neighbors, pets — well away. We coordinate directly with ComEd and other utility providers before any crew enters a downed-line zone.
Your homeowner's insurance policy also carries a duty to mitigate provision. This means you are expected to take reasonable steps to prevent additional damage after a covered loss. Failing to tarp a breached roof or secure an open wall can give an insurer grounds to dispute the portion of the claim attributable to the delay. Allied Emergency Services documents everything with time-stamped photos and provides written assessment reports that demonstrate you acted promptly and responsibly.
Finally, blocked driveways and egress routes are not just inconvenient — they can be life-threatening. Emergency vehicles must be able to access your property. If a downed tree is blocking your driveway or a shared access road, that is an immediate public safety issue in addition to a property damage event.

Oak Brook, Illinois is one of DuPage County's most prestigious and heavily wooded communities. Situated along the Salt Creek corridor and bordered by York Road, 22nd Street, Midwest Road, and I-88, Oak Brook's landscape is defined by mature hardwood canopy — towering oaks, elms, maples, and cottonwoods that have grown over decades on the Village's roughly 8.2 square miles. The same beautiful trees that make neighborhoods like Brook Forest Estates, Ginger Creek, and the areas surrounding the Oak Brook Center so attractive are also the ones most likely to fail during severe weather events, when a root plate weakens, a limb cracks from ice load, or a straight-line wind event pushes a 70-foot oak past its center of gravity.
Landmark properties throughout Oak Brook — from the grounds adjacent to Hamburger University and the McDonald's Campus, to the wooded lots near Fullersburg Woods Forest Preserve and the Salt Creek bicycle trail corridor — feature large, legacy trees that require skilled rigging and controlled dismantling when storm-damaged. Residents near the Butler National Golf Club and along the meandering Oak Brook Road corridor know that DuPage County's mature tree canopy, while stunning, comes with real storm-season risk. The Village's strict property maintenance codes also mean that hazardous trees and debris cannot simply be left in place — prompt professional removal is both a safety imperative and a code requirement.
Oak Brook's weather follows the greater Chicagoland severe weather pattern: peak storm season runs April through September, with the most dangerous severe thunderstorm and tornado watch events typically occurring in June and July. Derecho events — which produce widespread straight-line winds exceeding 80 mph — have historically caused some of the most extensive tree damage in DuPage County. Ice storms in late October through February add a second wave of tree hazards, as the accumulated weight of freezing rain on already-stressed branches causes spectacular and dangerous failures. Allied Emergency Services monitors weather across the entire Chicagoland region and pre-positions crews during major storm forecasts so response times remain fast even when call volume spikes.
Complete tree emergency response — from first call to final cleanup
When a storm drops a tree across your property — whether it's resting on your roof deck, crushing a vehicle in the driveway, collapsed onto a fence line, or simply blocking your only exit route — Allied Emergency Services responds with the right equipment and the right team to remove it safely. Storm-damaged trees present unique hazards compared to routine removal: the wood is often under extreme tension from the fall, root plates may be partially uprooted and unstable, and secondary branches may be loaded and ready to snap. Our crews assess the full situation before any cutting begins, identifying load paths and planning each cut to control where material falls.
A tree on a house is a dual emergency: structural damage AND weather exposure. Standard tree services remove the tree and leave — Allied Emergency Services removes the tree and immediately begins weatherization to protect your home from further damage. This matters enormously because Oak Brook summer weather can bring follow-on thunderstorms within hours of the initial event. Our crews carry commercial-grade 6-mil and 10-mil polyethylene tarps, OSB board-up panels, and all necessary fastening hardware to fully secure your structure on the same visit as tree removal. We also capture comprehensive photo and video documentation of all visible damage before, during, and after work — critical evidence for your insurance company.
Not every tree emergency involves a completely fallen tree. Hazardous hanging limbs — what arborists call "widow-makers" — are among the most dangerous tree conditions because they can fall without warning. A limb that partially split during a storm but remains attached by a strip of bark or a branch union is under unpredictable tension. Split trunks that appear intact may be held together by little more than a thin shell of sapwood. These situations require rigging expertise: our crews use block-and-tackle systems, friction devices, and aerial lift equipment to lower dangerous material in controlled segments, preventing it from falling onto structures, vehicles, or people below. For very large trees or unusually complex angles, we deploy crane equipment that allows us to lift and remove sections with precision.
Once the emergency is resolved and your property is secured, Allied completes the job with thorough site cleanup — because a safe property isn't just about removing the hazard, it's about restoring your yard to a condition where it's safe to walk, park, and use. Exposed stumps are trip hazards, root systems can attract pests, and large wood piles create fire risk and code violations. Our stump grinders reduce stumps to below-grade level, leaving a bed of wood chips that can be raked out or used as mulch. All trunk sections, limb debris, and wood waste are loaded and hauled away from your property — we don't leave a pile at the curb for you to deal with later. The site is left raked, cleared, and safe.
Understanding Oak Brook's storm pattern helps you prepare — and explains why Allied stays ready year-round.
The greater Chicagoland area sits squarely in the path of summertime derecho events — long-lived, fast-moving windstorms that can produce sustained straight-line winds of 60–90 mph across hundreds of miles. DuPage County has experienced multiple significant derecho events that caused widespread tree damage across Oak Brook and neighboring communities. The mature hardwood canopy in neighborhoods like Brook Forest and along the Fullersburg Woods corridor is particularly vulnerable to these events, as large trees with full leaf canopies present enormous wind resistance. A single derecho event can generate dozens of emergency tree calls across Oak Brook within a span of two to three hours — precisely why Allied pre-positions crews during major storm forecasts.
Spring in northeastern Illinois brings a rapid escalation of severe thunderstorm activity as warm Gulf moisture collides with cold Canadian air masses sweeping down from the northwest. April and May are peak months for tornado watches and warnings across DuPage County, though Oak Brook's urbanized landscape makes direct tornado strikes relatively uncommon. Far more frequent and damaging are the associated straight-line winds, large hail, and microbursts that accompany severe thunderstorms. Hail events can weaken branch unions and strip bark, predisposing trees to failure in subsequent storms. Spring thaw also softens root zones, making even healthy trees easier to uproot during high-wind events.
Perhaps the most structurally damaging weather events for trees in the Oak Brook area are autumn and winter ice storms. When freezing rain accumulates on branches and twigs, a single inch of ice can add hundreds of pounds to a large tree's canopy. Evergreens and trees that retain leaves into late autumn are especially vulnerable. Ice-storm damage often manifests not as full tree failures but as massive limb drops — sometimes occurring silently in the middle of the night or hours after the storm ends, as ice weight builds progressively. These limb drops are particularly dangerous because they can fall onto parked vehicles, power lines, and structures without the warning signals of a visible storm.
Oak Brook's tree population includes many mature specimens that are under stress from the Emerald Ash Borer, oak wilt, various fungal cankers, and the cumulative effects of construction-related root damage in developed areas. Stressed and diseased trees can fail even on calm days — a compromised root system, a hollow trunk, or an advanced canker makes a tree unpredictable. Residents who notice unusual leaning, large dead branches (called "snags"), fungal growth at the base, or significant bark damage should consult a certified arborist and, if a storm is forecast, call Allied Emergency Services proactively rather than reactively.
After a storm, it's tempting to grab a chainsaw and start cutting. We understand the impulse — your property is damaged, you want to take action, and you may have cut firewood or done routine yard work with a chainsaw before. But storm-damaged tree removal is categorically different from routine cutting, and it is consistently ranked among the most dangerous activities a homeowner can attempt. Here's why:
A tree that has fallen against a structure or into another tree is under enormous stored tension. The wood fibers are stretched and compressed in complex patterns that are not visible to the eye. When you make a cut into a tension-loaded trunk or limb, the wood can snap, kick, or spring violently in any direction — including directly toward you. Professional arborists and tree removal crews spend years learning to "read" tension in storm-damaged wood and plan their cuts to release that tension in controlled directions. Without this training, a single poorly planned cut can result in severe or fatal injury.
A large tree trunk on a slope — or even a gentle grade — can roll with explosive force when cut free from a limb that was acting as a brake. Root plates that appear anchored can release suddenly when tension changes, sending the root mass swinging like a pendulum. These dynamics are predictable to trained crews with rigging experience, but completely unexpected to a homeowner who has never worked around felled trees. Serious leg, foot, and crush injuries are common in untrained storm tree removal attempts.
Many storm tree situations require work above ground level — cutting limbs from a roof, working in an elevated position to clear a hanging section, or accessing a tree that is leaning over a structure. Ladder work with a running chainsaw is inherently dangerous under ideal conditions. After a storm, with wet surfaces, unstable debris, and potentially damaged structural elements, the risk is multiplied. Our crews use professional aerial lift equipment, rigging systems, and fall protection gear — not extension ladders from a garage.
Professional tree removal from structures uses block-and-tackle rigging systems that allow large sections of wood to be lowered in a controlled, deliberate manner rather than dropped. This protects your roof, your vehicles, your fencing, and the people working below. Crane-assisted removal goes further, allowing precise placement of large cuts that cannot be safely rigged. This equipment and expertise is simply not available to homeowners attempting DIY work.
If any downed lines are involved, only utility company personnel can safely authorize access. Allied coordinates directly with ComEd and other utilities before our crews enter hazard zones. Additionally, professional crews document the entire scene with insurance-grade photography and written assessments before removing anything — evidence that is invaluable during the insurance process. A homeowner who cuts the tree up before proper documentation may inadvertently eliminate evidence needed for their claim.
The bottom line: Call Allied Emergency Services at (800) 792-0212. We are faster, safer, and the result is properly documented for your insurance file.
We work alongside your insurance company to document damage and restore your property to pre-loss condition.
From the moment you call, our team mobilizes. We arrive on-site within our target response window, assess the full scope of the emergency, and immediately begin life-safety stabilization work: securing the structure against further damage, removing the immediate threat, and establishing a safe perimeter. No work begins without a walkthrough assessment and — except in immediate life-safety emergencies — a written authorization. Emergency tarping and board-up happen in the same visit as tree removal so your property is protected before our crew leaves.
Before, during, and after tree removal, our crews capture comprehensive time-stamped photographic and video documentation of all visible damage. This includes the tree impact zone, roof damage, wall damage, interior water infiltration evidence, and any secondary damage to gutters, soffits, fascia, HVAC units, and landscaping features. We compile this documentation into a detailed written assessment report that describes damage locations, dimensions, and materials affected — exactly what your insurance company needs to process your claim efficiently. Good documentation at this stage can prevent disputes and delays later in the process.
Allied works alongside your insurance carrier throughout the repair process. We provide our written damage report and photo documentation to support the adjuster's assessment. Our estimators prepare detailed repair scopes using Xactimate — the industry-standard estimating platform used by most insurance carriers — so that our scope of work aligns with the documentation your adjuster is reviewing. We communicate directly with your carrier's representatives when needed to clarify scope items or provide supplemental documentation. This experience helps keep the process moving without placing the burden of vendor coordination entirely on you during an already-stressful situation.
Once the insurance process reaches an approved scope and you have authorized Allied to proceed with repairs, our licensed restoration crews complete all structural and interior restoration work. This can include roof replacement or repair, attic structural repairs, water-damaged insulation removal and replacement, drywall repair, interior painting, window and door replacement, siding repair, and complete site cleanup including stump grinding and debris haul-away. Allied is a full-service restoration contractor — you deal with one company from the emergency call through the final restoration, not a different vendor for each phase of work.
Before we close out any project, a project manager conducts a thorough final walkthrough with you to review all completed work against the authorized scope. We verify that every item in the repair scope has been completed to your satisfaction, that all materials match the agreed specifications, and that the property is fully restored to pre-loss condition. Any punch-list items identified during the walkthrough are addressed promptly. We want you to feel confident that your home is fully restored — not just structurally repaired, but cosmetically complete and ready for normal occupancy.

"A massive oak came down on our garage roof during a Thursday night storm — the tree was 18 inches in diameter and had crushed the rafters completely. I called Allied at 11:30 PM and they had a crew at our Brook Forest home by 12:45 AM. They removed the tree, tarped the entire garage roof, and had it completely boarded and secured before 4 AM. The crew was calm, professional, and incredibly efficient under difficult conditions. I cannot thank them enough for protecting the rest of our garage contents from the rain that came through the next morning."
"We had a large silver maple split down the center during last summer's derecho — half of it was leaning against our fence and the other half was resting on the corner of our sunroom. Allied came out within an hour and a half and I was amazed at how methodically their crew handled it. They used rigging to lower the section off the sunroom without dropping any weight onto the roof, then cleared the fence section and ground the stump in the same visit. Their documentation photos were detailed enough that our insurance adjuster approved the claim without a single dispute."
"I called four companies after a tree fell across our driveway — Allied was the only one who picked up at 6 AM on a Saturday, and they were on-site by 7:15. The crew cleared the driveway so my husband could get to work, then came back that afternoon to section up the trunk and haul everything away. The price was fair and completely transparent — no surprises on the final invoice. When I asked about the roof damage on the corner of the garage, they took photos, gave me a written damage report, and helped me understand what my homeowner's insurance would likely cover. Exceptional service from start to finish."
From your first call to a fully secured property — here's exactly what Allied does.
When you call (800) 792-0212, a live Allied team member answers — not an answering machine, not a callback system. We gather your location, assess the nature of the emergency, and confirm whether any utility lines, gas, or immediate life-safety hazards are involved. We dispatch the nearest available crew before you hang up.
Our crews serving the western suburbs and DuPage County are positioned to reach most Oak Brook addresses within 60 minutes. During major storm events when call volume is elevated, we prioritize calls involving structural damage — trees on occupied structures receive immediate priority dispatch over clear-yard situations.
Upon arrival, our crew chief conducts a rapid but thorough assessment of the scene: tree position and tension loading, structural damage extent, utility hazards, equipment access constraints, and scope of weatherization needed. We provide you with a verbal overview and written authorization form before any cutting begins.
We capture comprehensive time-stamped photos and video of the scene before any material is disturbed. This documentation is your evidence — it shows the adjuster exactly what happened and what the damage looked like in its original post-storm state. This step takes minutes but is invaluable for your insurance process.
Removal proceeds methodically: tension assessment, rigging setup if needed, controlled sectional cutting from top to bottom, and careful extraction from the structure. Nothing is dropped. Every cut is planned. Utility coordination happens before any aerial work begins. The structure is protected throughout the removal process.
Immediately following tree removal, tarps go on and boards go up. We do not leave your property with an open roof or broken windows. Commercial-grade materials are installed properly — not just draped — to withstand additional weather until permanent repairs can be made. Your property is fully secured before our crew leaves the site.
Our team responds within 1 hour — don't let damage get worse.
