July 27, 2026 Orland Park Tornado: EF0 Track, Wind, Hail and Flooding

July 27, 2026 Orland Park Tornado: EF0 Track, Wind, Hail and Flooding

Article updated July 30, 2026. Event information reflects the National Weather Service Chicago update posted at 2:40 p.m. CDT on July 30.

The National Weather Service confirmed that an EF0 tornado touched down in Orland Park, Illinois, on Monday, July 27, 2026. The NWS event table lists the Orland Park tornado from approximately 12:34 to 12:38 p.m. local time, with a 2.9-mile track.

As of the July 30 update, NWS Chicago had confirmed seven tornadoes across its area of responsibility: five EF0 tornadoes and two EF1 tornadoes. The same severe weather event produced hail as large as 3 inches in diameter, widespread wind damage, torrential rain and areas of flash flooding. In some of the hardest-hit parts of southern Cook County and eastern Will County, NWS reported straight-line wind gusts of 80 to more than 90 mph.

Tornado-count clarification

Some initial community information described the Orland Park tornado as one of five tornadoes. The later NWS Chicago update supplied for this article lists seven total confirmed tornadoes. Five of the seven were rated EF0, including the Orland Park tornado, while two were rated EF1.

Because storm surveys may continue after an event, the total and individual track details should always be attributed to a dated National Weather Service update.

July 27, 2026 Chicago-area severe weather statistics

The seven tornado tracks listed in the supplied NWS table had a combined listed length of 24.5 miles. Allied Emergency Services calculated the following summary directly from those seven track lengths:

Statistical summary	Result
Confirmed tornadoes	7
Combined listed track length	24.5 miles
Average track length	3.5 miles
Median track length	2.5 miles
EF0 tornadoes	5, or approximately 71%
EF1 tornadoes	2, or approximately 29%
Longest listed track	11.4 miles
Orland Park track	2.9 miles

These calculations reflect the tornado list available in the NWS update supplied for this article and may change if later survey information revises a rating or path.

The Country Club Hills–Glenwood tornado also affected portions of Hazel Crest, Markham, Harvey, East Hazel Crest and Homewood. The Lynwood–Munster tornado also affected portions of Lansing, Illinois.

What caused the July 27 severe weather?

According to the NWS Chicago event overview, intense heat and oppressive humidity produced extreme atmospheric instability across the region. A weather disturbance interacting with that instability generated a relatively narrow corridor of thunderstorms from eastern Wisconsin into northeastern Illinois during the late morning.

An unusually high degree of wind shear allowed some storms to become severe quickly. Intense supercell thunderstorms then moved southeast, producing tornadoes, damaging hail and extensive wind damage. A later line of storms originating in eastern Wisconsin caused additional scattered wind damage across parts of the Chicago metropolitan area.

The exceptionally moist air mass also supported torrential rainfall rates. Those intense downpours caused localized flooding, including notable flash flooding in suburbs outside Chicago.

Was all of the damage caused by the Orland Park tornado?

No. A tornado track represents only one part of a larger severe weather event.

The National Weather Service reported that most of the damage in and near the Chicago metropolitan area was caused by strong to destructive straight-line winds, rather than tornadoes. Portions of southern Cook County and eastern Will County were among the hardest hit.

Communities identified by NWS included:

• Chicago Heights, Ford Heights, Sauk Village and Steger
• Crete, Monee, University Park and Frankfort
• Beecher and nearby areas of southern Cook and eastern Will counties

Some of these locations experienced estimated or measured wind gusts of 80 to more than 90 mph, resulting in substantial tree damage and multiple instances of notable structural damage.

For property owners, the distinction between tornado and straight-line wind is important for understanding the event, but both can lift roof coverings, break windows, remove siding, damage gutters, topple trees and allow water into a structure. The cause at a specific building should be evaluated through a documented property inspection.

What Orland Park property owners should inspect after the storm

An EF0 rating does not mean every affected property experienced minor damage. Tornado ratings describe the surveyed event; they do not determine the repair cost or condition of an individual home or commercial building.

Property owners should not climb onto a wet, steep or damaged roof. Many storm-related defects can be difficult to identify without safe access and professional inspection.

Roof and attic damage

Potential signs of Orland Park storm damage include:

• Missing, lifted, folded or creased shingles
• Displaced ridge caps or damaged roof edges
• Punctures from branches or windborne debris
• Dented metal vents, flashing and roof accessories
• Cracked skylights or damaged chimney components
• Exposed roof decking or torn underlayment
• Wet attic insulation, daylight through the roof or active dripping
• Ceiling stains that appear hours after the storm

Wind damage may occur without removing an entire shingle. A shingle can be unsealed, creased or fractured while appearing relatively normal from the ground.

Siding, windows, gutters and decks

Inspect exterior walls and openings for:

• Loose, cracked, punctured or missing siding
• Dents in aluminum siding, fascia, gutters and downspouts
• Broken glass, damaged screens or failed window seals
• Water entering around window and door openings
• Detached soffit or fascia
• Gutters pulled away from the roof edge
• Deck railings or stairs loosened by falling limbs
• Deck framing, posts or ledger connections displaced by impact

Cosmetic damage should not be assumed to be the only issue. Siding or trim damage can expose the water-resistive layer and concealed wall components to rain.

Water, electrical and structural damage

Seek immediate professional help when there are signs of:

• Sagging ceilings or wet drywall
• Saturated insulation or standing water
• A wet electrical panel, outlets or wiring
• Gas odors or damaged utility equipment
• Racked door or window openings
• New structural cracks
• Bowed walls, shifted framing or roof sagging
• Unstable trees or branches over the building

Do not enter an area with a suspected electrical, gas, collapse or falling-tree hazard. Contact emergency services or the appropriate utility when life safety is involved.

What to do after Orland Park storm damage

Property owners can take the following steps while protecting personal safety:

1. Address immediate hazards. Stay away from downed electrical lines, damaged utility equipment, unstable trees and visibly compromised structures.
2. Photograph the property before cleanup. Capture wide views of each elevation, close-up damage, interior water intrusion, debris and damaged personal property.
3. Prevent additional damage when it is safe. Temporary roof tarping, board-up work, water extraction and moving undamaged contents may reduce further loss.
4. Keep receipts and a written activity log. Record emergency expenses, contractor visits, insurer communications and the date each condition was discovered.
5. Notify the insurance carrier. Report the loss promptly and ask what documentation, inspections and temporary repair procedures are required under the policy.
6. Avoid unnecessary permanent work before documentation. Emergency mitigation should not be delayed, but non-emergency reconstruction should be coordinated with the insurer and documented carefully.
7. Arrange a qualified storm damage inspection. The inspection should address the roof, siding, windows, gutters, attic, interior moisture and visible structural conditions.

An NWS storm report helps document that severe weather occurred in the region, but it does not by itself prove the cause or extent of damage at a particular address. Property-specific photographs, measurements, inspection findings and repair estimates remain important.

Cook County residential damage self-assessment survey

The Village notice supplied for this article asked residents with storm damage to complete the Cook County residential damage self-assessment survey by August 5, 2026.

The purpose of the survey is to help local officials document the event’s overall impact and pursue any assistance that may become available. Completing the community survey is separate from reporting an insurance claim and does not guarantee financial assistance.

Residents should use only an official Village, County or verified government link. Storm-related messages requesting unusual payments or sensitive information should be treated cautiously.

How much can Orland Park storm damage repair cost?

The cost of Orland Park storm damage restoration is not determined by the EF rating. Pricing depends on the measured damage, building size, roof slope, number of stories, access, material availability, emergency conditions, code requirements, permit fees and whether structural drying or engineering is needed.

The following broad figures are for preliminary budgeting only. They are not quotes, verified July 2026 market averages or insurance coverage determinations. Allied should approve or replace these ranges with current local pricing before publication.

Storm restoration service	Broad planning range
Emergency roof tarp or limited board-up	$350–$2,500+
Localized roof repair	$750–$4,000+
Full asphalt-shingle roof replacement	$10,000–$30,000+
Localized siding repair	$750–$5,000+
Full siding replacement	$15,000–$40,000+
Window, glass or exterior trim work	$500–$2,000+ per opening
Gutter and downspout replacement	$1,500–$6,000+
Water extraction and structural drying	$2,000–$10,000+
Emergency tree or debris removal	$750–$6,000+
Structural framing or major reconstruction	Site-specific inspection and scope required

A complete written estimate should distinguish among:

• Emergency mitigation and temporary protection
• Demolition and debris disposal
• Labor and permanent materials
• Roof decking, wall sheathing or concealed damage
• Water extraction, drying and microbial prevention
• Permit and inspection costs
• Code-required components
• Engineering or specialized access
• Taxes, overhead and other documented project expenses

Two estimates with very different totals may not include the same work. Property owners should compare line-item scope, quantities, materials, permit responsibility and code compliance—not only the final price.

Orland Park Storm damage Repair

Orland Park building code and permit considerations

Permanent storm repairs should comply with the codes and amendments currently adopted by the Village of Orland Park, applicable Illinois requirements, manufacturer installation instructions and permit conditions.

The exact code editions and local amendments should be confirmed with the Village before permanent construction begins. Depending on the property and scope, the applicable framework may include locally adopted versions of the International Residential Code, International Building Code and related electrical, mechanical, plumbing and energy provisions.

Code items that may affect a storm repair scope

For roofing work, the contractor should evaluate:

• Existing roof-covering layers and whether removal is required
• Roof deck condition and replacement of deteriorated sections
• Underlayment and ice-barrier requirements
• Drip edge, valleys, wall flashing and roof penetrations
• Roof ventilation
• Fastener type, placement and wind-resistant installation
• Manufacturer-approved installation details

For siding and exterior wall work, the scope may need to address:

• Water-resistive barriers
• Flashing around windows, doors and wall penetrations
• Required siding clearances and fastening
• Concealed sheathing damage
• Manufacturer installation requirements

For windows, doors and structural repairs, applicable issues may include:

• Opening flashing and water management
• Safety glazing in required locations
• Emergency escape and rescue opening requirements where applicable
• Structural framing, sheathing and connections
• Engineering review for significant movement or impact
• Electrical inspection when wiring or service equipment is affected

The goal is not simply to restore the appearance of the building. The permitted repair must satisfy the requirements that apply to the actual scope. Code-related work and permit expenses should be documented separately in the estimate. Insurance coverage for upgrades or ordinance-and-law items depends on the individual policy.

Insurance documentation after wind, hail and water damage

Insurance coverage depends on the policy language, cause of loss, deductible, exclusions and endorsements. Wind, hail, roof-related water intrusion, sewer backup and surface flooding may be evaluated differently.

Useful documentation includes:

• Date- and time-stamped photographs
• Video of each affected room and exterior elevation
• A room-by-room damage inventory
• Moisture readings and drying records
• Temporary repair invoices
• Contractor measurements and photographs
• Permit or code information
• Written insurer communications
• The NWS event page and local storm reports

Property owners should ask the carrier how the policy treats emergency mitigation, matching materials, hidden damage, code-required work, debris removal and water entering from different sources.

How to avoid storm-repair scams

Severe weather often brings an increase in high-pressure sales activity. Before signing a storm restoration agreement:

• Verify credentials currently required for the trade and jurisdiction.
• Request proof of general liability coverage and workers’ compensation where applicable.
• Confirm who will obtain permits and schedule inspections.
• Require a written scope identifying materials, quantities, payment terms and warranties.
• Do not sign blank contracts, blank claim documents or incomplete authorizations.
• Avoid contractors who guarantee that an insurance company will pay for all work.
• Do not make a large payment solely because a salesperson claims materials will otherwise be unavailable.
• Confirm the contractor’s business identity, physical contact information and references.
• Read cancellation, financing and dispute provisions before signing.

A reputable storm restoration contractor should be able to explain the difference between emergency mitigation, permanent repairs, insurance documentation and code-required construction.

Orland Park storm recovery summary

The confirmed Orland Park tornado was one part of a larger and unusually intense July 27 severe weather event. Although the Orland Park tornado was rated EF0, NWS findings show that tornadoes were not the only serious hazard. Destructive straight-line winds, large hail and torrential rain caused widespread damage throughout the Chicago region.

Prompt documentation, safe temporary mitigation, a complete property inspection and a code-compliant repair scope can help reduce additional damage and support an organized recovery.
