A tree on a structure lets water in with every rainfall — we remove, tarp and secure in one visit, 24/7
When a tree strikes a structure in Chicago, the clock starts immediately. A punctured roof is not a problem that waits until morning — every rain shower, every dew-heavy night, every passing storm band forces additional water through that opening. Within hours, water can penetrate roof decking, insulation, ceiling drywall, and interior framing. What begins as a tree removal can quickly compound into a full mold remediation and interior structural repair if the opening is left unsealed overnight or through a weekend.
Beyond water intrusion, a partially fallen or hanging tree presents severe secondary collapse risk. Damaged limbs shift as wood fibers continue to fail, and root systems that partially held can give way hours after the initial drop. The weight distribution on a compromised tree changes dynamically — what looks stable at 8 PM can shift catastrophically by 2 AM. Never attempt to enter the impact area, walk under hanging branches, or try to prop a leaning tree yourself.
If the fallen tree has contacted or severed utility lines, treat every line as energized until ComEd or the relevant utility officially declares it safe. Downed lines can energize the ground, fences, and even standing water around them. Keep all people and pets away and call 911 immediately. Allied Emergency Services coordinates directly with utility companies before beginning removal near any infrastructure — our crews are trained in utility hazard protocols.
Your homeowners insurance policy almost certainly contains a mitigation duty clause, requiring you to take prompt, reasonable steps to prevent further damage after a covered loss. Failing to act quickly can give an insurer grounds to reduce or contest the additional damage portion of a claim. Calling a licensed restoration contractor immediately — and getting the structure tarped and secured — demonstrates you fulfilled that duty. Do not wait. Call (800) 792-0212 right now and let our Chicago team respond.
Chicago is one of the most geographically complex urban markets in the Midwest for emergency tree work. The city's famous tree canopy — lined along boulevards from Logan Square to Beverly, through the mature oaks of Hyde Park to the elms of Lincoln Square — is one of its greatest assets. It is also one of its greatest liabilities when severe weather strikes. Chicago's lakefront position along Lake Michigan creates a unique storm corridor: cold fronts barreling down from Wisconsin meet Gulf moisture tracking north from Missouri and Indiana, producing some of the most intense convective thunderstorms in the continental United States. Wind shear events, derecho lines, and isolated supercells can produce damaging wind gusts exceeding 70 to 80 mph with little warning, even on days that started sunny.
The Chicago metro sits at the intersection of multiple storm tracks. Neighborhoods on the North Side — Wrigleyville, Andersonville, Ravenswood, Edgewater, Rogers Park — frequently experience the most violent leading-edge winds as fast-moving storm lines approach from the northwest, tracking along the lake shoreline. The South Side neighborhoods of Chatham, Woodlawn, South Shore, and Pill Hill see elevated damage during tornadic activity and straight-line wind events that track from the southwest. The Near West Side — Pilsen, Little Village, Lawndale — sits in a zone where urban heat effects intensify storm convection, leading to localized severe micro-bursts. Dense neighborhoods like Bucktown, Wicker Park, and Ukrainian Village have trees planted in narrow parkways between concrete sidewalks and streets, making root systems shallow and trees more susceptible to wind throw than their rural counterparts.
Proximity to Millennium Park, Lincoln Park, Jackson Park, and other major green spaces means post-storm tree hazards can affect both private property and public corridors simultaneously. Schools like Lincoln Elementary, Amundsen High School, Whitney Young, and South Shore International College Prep are surrounded by mature urban trees that require emergency response protocols when storm damage threatens access or nearby structures. Allied Emergency Services understands Chicago's unique urban tree environment, its alley-access logistics, its dense parking constraints, and the speed required to move through city traffic with heavy equipment after a major storm event.
Every storm event is different. Our crews are equipped and trained for the full spectrum of tree emergency scenarios — from a single downed limb to a 60-foot oak across a roof ridge.
When a storm sends a tree crashing onto your roof, vehicle, fence, or yard in Chicago, the priority is getting it removed safely and quickly before additional damage occurs. Storm-damaged trees present unique hazards that routine tree trimming does not: wood fibers are fractured under unpredictable tension loads, root systems are partially destabilized, and the tree's weight distribution has changed dramatically from its standing position. Our crews perform a full site assessment before making a single cut, identifying tension lines, compression zones, and secondary hazards that must be addressed in a specific sequence.
Tree down in Chicago? (800) 792-0212 — 24/7.
A tree impacting an occupied or insured structure is the highest-priority emergency call we receive. In Chicago's dense residential neighborhoods, the consequences of delayed response are severe: water intrusion begins with the next rainfall, ceiling systems can fail from accumulated weight, and mold colonization in wet insulation can begin within 24 to 48 hours. Our tree-on-structure response protocol combines emergency tree removal with immediate structural stabilization — including heavy-duty polyethylene roof tarping and emergency board-up of window, door, and wall openings — all in one visit by one coordinated crew.

Not every tree emergency involves a complete fallen tree. Some of the most dangerous situations involve large-diameter "widow maker" limbs that are cracked, split, or hanging partially broken in the tree canopy — held up only by strips of bark or bark tension and ready to drop without warning. In Chicago's urban environment, these hazardous hanging limbs can threaten pedestrians on sidewalks, vehicles parked below, rooftop HVAC units, and adjacent structures. Our crane and bucket truck capability allows us to access and remove these limbs safely without ladders or dangerous climbing in compromised canopy sections.
Hanging limb or split trunk? (800) 792-0212 — don't wait for it to fall.
After the emergency is resolved and the structure is secured, you're left with a stump, a yard full of wood debris, and potentially tons of chips and organic material scattered across your property. Allied Emergency Services provides complete post-removal cleanup services that return your property to a safe, clean condition. Our stump grinders can access tight Chicago parkway strips, side-yard gates, and rear alleys to process stumps down to approximately 8 inches below grade — eliminating the trip hazard, the visual eyesore, and the root decay that can attract termites and other wood-destroying insects to your property perimeter.

Chicago's position at the edge of the Great Plains storm corridor and along Lake Michigan's eastern shore makes it one of the most storm-active major cities in the United States. Understanding the pattern of severe weather here explains why a 24/7 emergency tree response capability is not a luxury — it is a necessity.
The most destructive tree events in Chicago typically arrive as derecho lines — fast-moving, organized complexes of severe thunderstorms that can maintain damaging wind gusts of 60 to 90+ mph over hundreds of miles. These events often strike with 30 minutes or less of warning. A typical summer derecho line can down thousands of trees across the Chicagoland area in a single pass, overwhelming municipal tree crews and standard arborists for days. Neighborhoods from Jefferson Park on the northwest to South Chicago on the southeast can be affected in the same event. Allied Emergency Services maintains surge capacity protocols and deploys all available crews during confirmed large-scale storm events.
Tornado and severe thunderstorm season in northeastern Illinois peaks in the spring months, when strong jet stream energy interacts with rapidly warming surface temperatures. Tornado watches and warnings affecting Chicago and surrounding Cook, DuPage, Kane, Lake, and Will Counties occur most frequently during this window. While violent tornadoes directly impacting the dense urban core are relatively rare, EF0 and EF1 tornadoes tracking through suburban and outer neighborhood areas cause significant tree damage, and the accompanying straight-line winds and large hail weaken trees across the entire metro. Trees already stressed by late winter ice loading or spring freeze-thaw cycles are especially vulnerable to spring wind events.
Remnant energy from Gulf Coast tropical systems occasionally tracks north into Illinois during late summer, producing extended periods of heavy rainfall that saturate urban soils. Chicago's clay-heavy soil retains water poorly, and when it becomes oversaturated, root systems lose the mechanical anchoring that keeps large trees upright. Trees in parks, parkways, and rear yards — particularly older maples, ashes, and cottonwoods — are prone to root-failure windthrow even in relatively modest wind conditions following a prolonged wet period. These "soil saturation events" can produce tree falls on calm days with no storm at all, simply because the ground can no longer hold the root ball.
Chicago's winter ice storms are among the most destructive tree events the region experiences. When freezing rain coats a mature tree, the accumulated ice can add hundreds to thousands of pounds of weight to a canopy that was never designed to support that load. Branch failures during ice storms are widespread and often affect trees that appeared perfectly healthy before the event. Ice-coated limbs can drop suddenly hours or even days after the initial ice accumulation, as temperatures fluctuate through freeze-thaw cycles. Structures, vehicles, and people below are at risk long after the storm itself has passed. Allied Emergency Services responds to ice-storm tree emergencies throughout Chicago's winters — never letting weather conditions be a reason we can't reach your property.
Chicago's urban forest has been devastated by the Emerald Ash Borer, an invasive pest that has killed tens of millions of ash trees across Illinois. The Chicago region alone lost a significant portion of its ash canopy, which represented a large fraction of parkway and park trees planted in previous decades. Dead ash trees become structurally compromised far faster than most homeowners expect — within two to three years of death, a standing ash can be internally hollow and structurally unpredictable. Storm events that would not have toppled a healthy tree can send a dead or dying ash crashing down. If you have dead or declining ash trees near your structure, don't wait for the next storm to make the decision for you.
Every year, homeowners are seriously injured or killed attempting to remove fallen or damaged trees using chainsaws and ladders. Emergency tree removal — particularly involving storm-damaged trees resting on structures or partially uprooted — is widely considered one of the most dangerous residential tasks a non-professional can attempt. The hazards are not intuitive, and they are not the same as cutting a healthy standing tree. Storm-damaged trees are in a completely different category of risk.
The physics of loaded tension in storm-damaged trees are deadly for untrained operators. When a large branch or trunk section is pinned under its own weight or braced against a structure, the wood fibers are under enormous compression and tension simultaneously. Making the wrong cut — or the right cut in the wrong sequence — can cause the log to kick back violently, spring upward with thousands of pounds of force, or roll in an unexpected direction. A chainsaw "kickback" from a pinched bar can cause fatal injury in a fraction of a second. Professional crews spend years learning to read the tension geometry of a downed tree, identify the "hinge" and "back cut" positions, and sequence cuts to release load in a controlled direction.
Ladder work on a compromised roof or structure is categorically unsafe for untrained individuals. A roof that has been struck by a tree may look solid but have fractured rafters, compromised sheathing, or displaced flashing that cannot support a person's weight in ways that are not visible from the ground. Professional restoration crews have the training and equipment to safely work on compromised structures, assess load-bearing capacity in real time, and set up proper fall protection when working at height.
Crane and rigging capability separates emergency professionals from standard tree services. In Chicago's dense urban environment, there is often no room to simply "let it fall." Trees must be disassembled in carefully rigged sections, with each piece lowered in a controlled manner to avoid secondary damage to roofs, fences, vehicles, utility lines, and neighboring properties. This requires not just a chainsaw, but a rigging system of ropes, pulleys, and friction devices operated by multiple trained crew members in coordinated sequence. Many standard arborists do not carry crane capability — Allied does.
Utility hazard coordination requires professional relationships and protocols. When tree removal must occur near power lines, gas meters, or other utility infrastructure, work cannot legally or safely proceed without proper coordination with ComEd, Peoples Gas, or the relevant utility provider. Allied Emergency Services has established relationships with Chicago-area utility companies and follows documented safety protocols for work in proximity to energized infrastructure. An untrained homeowner has none of these resources.
Insurance documentation is a professional discipline, not just taking photos. Insurance-grade damage documentation involves systematic photography of all affected surfaces, written damage assessments that identify primary impact zones versus secondary damage, moisture readings, and documentation that follows the sequence of events in a way that supports the insurance review process. Allied's documentation package is prepared specifically to give your insurance adjuster what they need to process your claim efficiently — reducing back-and-forth delays and ensuring damage is fully captured before any evidence is disturbed by weather or repair work.
Bottom line: when a storm puts a tree on your roof in Chicago, the best thing you can do is get out of the immediate hazard area, call 911 if there is life safety risk, and then call Allied Emergency Services at (800) 792-0212. We handle the danger so you don't have to.
Navigating a property insurance claim after tree damage doesn't have to be overwhelming. Allied Emergency Services is experienced in working alongside homeowners through the restoration process, from the first emergency call through final walkthrough.
From the moment you call, our priority is life safety and property stabilization. Our crew arrives, secures the scene, removes the tree using controlled dismantling techniques, and immediately installs emergency roof tarping and board-up to prevent further weather intrusion. This first-response visit stops the bleeding — physically and financially. We document everything before we begin and throughout the removal process.
After stabilization, our team conducts a systematic damage assessment of all affected areas. This includes high-resolution photography of all impact zones, moisture readings in affected interior spaces, written narratives describing the sequence and extent of damage, and identification of all affected building components — roofing, sheathing, framing, insulation, drywall, windows, siding, gutters, and any mechanical systems in the impact path. This documentation package is organized and ready to hand to your insurance adjuster or provide for their review.
We work alongside you and your insurance company throughout the claim review process. When your adjuster schedules an inspection, our project manager can be present to walk them through the damage documentation, answer questions about scope, and provide restoration cost estimates in a format your insurer recognizes. We are restoration contractors who repair damage — we do not negotiate or settle claims. Our role is to ensure the physical scope of damage is thoroughly understood and that the repairs we perform are correctly described and priced.
Once the claim scope is established and work is authorized, Allied Emergency Services performs all restoration work using licensed, insured subcontractors and employees. Roofing repairs are performed to manufacturer specification and local building code requirements under our Illinois Roofing Contractor License #104.019029. Structural framing repairs, drywall, insulation, painting, window replacement, siding repair, and gutter work are all performed or managed within our restoration scope. You work with one point of contact throughout the entire repair process — not a revolving door of separate contractors.
When all restoration work is complete, our project manager conducts a comprehensive final walkthrough with you. Every repaired surface is inspected against the original damage documentation to confirm complete scope completion. We verify that roofing, flashing, interior repairs, and exterior components are all finished to standard, and we address any punch-list items before closing the job. Your satisfaction — and the structural integrity of your property — is the measure of a completed job.
Reviews represent typical customer experiences.
"A massive cottonwood came down across our entire back porch during the July storm — it was terrifying. I called Allied at 11:30 PM and they had a crew at my house in Bridgeport by 12:45 AM. They tarped the roof the same night, and by morning I felt like the situation was actually under control. I can't say enough about how professional and calm the crew was. When the insurance adjuster came out the next day, Allied's documentation made the whole process smooth."
"An old silver maple split right down the middle during a wind storm and half of it landed on my garage in Jefferson Park. Allied was there within the hour. They removed the tree in sections using ropes and equipment I didn't even know existed — nothing else was damaged in the process. The garage roof was tarped before they left. When I was dealing with my insurance company, their paperwork was exactly what the adjuster needed. Professional from first call to final handshake."
"I had an ash tree in my parkway that died from the borer and a storm finally sent it across my neighbor's fence and into the corner of my house in Chatham. My neighbor and I were both worried about who was responsible for what. Allied came out, assessed the whole situation, removed the tree cleanly without any additional damage, documented everything, and helped us both understand how our respective insurance situations would work. They handled the board-up and tarp that night. Total professionals who clearly knew Chicago inside and out."
When you dial (800) 792-0212, a live dispatcher answers — any hour, any day. No voicemail, no callback queue. Tell us your location, describe the situation briefly, and our dispatcher begins routing the nearest available crew while you're still on the phone. We will give you an estimated arrival time before we hang up.
Our Chicago-area crews are staged to respond across the metro with a target arrival time of 60 minutes or less from your call. After major storm events, we triage by structural impact severity — tree on occupied structure or blocking emergency access is dispatched first. You will receive a confirmation call or text when the crew is en route with updated ETA.
Our crew leader conducts a full site assessment before any work begins. Hazards are identified — utility proximity, secondary fall risk, structural stability — and a safe work zone is established. You will be briefed on exactly what we plan to do and in what sequence before a single cut is made. Pricing is presented transparently and agreed upon before work begins.
Using rigging, bucket trucks, or crane equipment as needed, the tree is systematically dismantled from the impact point outward. Each section is carefully controlled in its descent to prevent secondary property damage. Wood is cut and staged for haul-out as the work progresses. Photographic documentation is maintained throughout the removal process for your insurance file.
With the tree removed, we immediately move to structural stabilization. Heavy-duty polyethylene tarping is installed over any roof penetrations, secured to prevent wind uplift. Windows, doors, and wall openings are boarded up with OSB panels. Interior is checked for active water intrusion. When we drive away, your property is weather-tight, secured, and documented.
Our team responds within 1 hour — don't let damage get worse.
