Mesa & Phoenix Hail Storm, October 20–21, 2026: How to File Your Hail Damage Insurance Claim

TL;DR. Two hailstorms hit the Phoenix metro on back-to-back days. October 20, 2026 (Tuesday night): Chandler, Gilbert, Tempe and Mesa, with hail up to 2 inches in northeast Mesa. October 21, 2026 (Wednesday afternoon): North Phoenix, Deer Valley, Glendale and Peoria, with 1.25- to 2-inch hail. Write down your date of loss, photograph everything, report the claim promptly, and get an independent roof inspection before the insurance adjuster’s visit. Commercial buildings and churches face larger percentage deductibles and should read the policy before accepting any scope.

The October 2026 hail storm was not a typical monsoon event. It arrived after monsoon season ended, as a fall low-pressure system pushed severe thunderstorms across central Arizona. The AP reported it prompted the state’s first tornado watches since October 2010. Roofers across the East Valley were finding hail damage on roof after roof the next morning.

If your home, rental, business, apartment complex or church took hail, this guide covers what happened where, what the damage looks like on each roof type, and how to file a hail damage insurance claim that pays for the full repair. Copper State Adjusting is a licensed Arizona public adjuster based in Mesa, on Brown Rd., inside the area the October 20 storm crossed.

Where Did Hail Hit in the October 20–21, 2026 Storm?

These are the National Weather Service Phoenix local storm reports, in Arizona time. Each report is one observer at one spot, so hail also fell between the points listed. You can check every entry on the Storm Prediction Center’s report pages for October 20 and October 21, and at NWS Phoenix.

October 20, 2026 — Chandler, Gilbert, Tempe and Mesa (Tuesday night)

Time (MST)	Location	Hail size
10:05 PM	3 NW Chandler	0.75–0.88 in., rapidly accumulating
10:06 PM	2 W Chandler	0.50 in.
10:10 PM	3 W Gilbert (Arizona Ave. and Elliot Rd.)	1.00 in. (quarter)
10:10 PM	3 SW Mesa	1.00 in. (quarter)
10:22 PM	3 ENE Mesa	1.00 in., measured
10:25 PM	3 ENE Mesa	1–2 in., the night’s largest

The NWS described a supercell moving from Chandler northeast through Mesa toward Fountain Hills, with warnings for 60 mph gusts and half-dollar hail over Mesa, Tempe, Gilbert, Chandler, Scottsdale, Falcon Field and the Salt River Pima-Maricopa Indian Community. Power lines came down in northeast Mesa at 10:20 PM. Neighborhoods around University Drive and Gilbert Road reported toppled trees, carport collapses and broken windows.

October 21, 2026 — North Phoenix, Deer Valley, Glendale and Peoria (Wednesday afternoon)

Time (MST)	Location	Hail size
3:25 PM	4 ENE Peoria; 5 NE Glendale	1.00 in.
3:30 PM	4 SSE Deer Valley	1.75 in. (golf ball)
3:30 PM	5 SSW and 6 SSE Deer Valley	1.25 in. (half dollar)
3:34 PM	4 NE Glendale	2.00 in., the afternoon’s largest
3:35–3:45 PM	4 S, 4 E and 5 ENE Deer Valley	1.50–1.75 in.
4:05 PM	4 E Carefree	0.88 in.

A 60 mph gust was measured near Glendale at 3:30 PM. Apartment complexes near 19th Avenue and Dunlap, and near 19th and Peoria avenues, reported shattered windows and windshields. Later that afternoon, a second round of warnings covered east Mesa, Usery Mountain Park, Apache Junction, Fountain Hills and Saguaro Lake.

How big was the October 2026 hail storm?

Canopy Weather, a private weather-analytics firm, modeled the October 21 hail outbreak at about 10,300 claims and $242.5 million in losses across Arizona, Nevada, Utah and New Mexico, and about $379 million across nine Arizona counties over three days, as reported by Roofing Contractor. Those are modeled projections, not verified claims. Local roofers expect a month or two of backlog, far shorter than the historic 2010 Phoenix hailstorm, but long enough that early inspections matter.

What Is My Date of Loss?

Your date of loss is the date the storm damaged your property, and it goes on every claim form. Getting it right matters, because the insurer will check it against weather data.

Mesa, Chandler, Gilbert, Tempe, East Valley: most likely October 20, 2026.
North Phoenix, Deer Valley, Glendale, Peoria, Carefree: most likely October 21, 2026.
East Mesa, Usery Mountain, Apache Junction, Fountain Hills: possibly either day. Warnings covered this area both nights.

If you are not sure, write down what you saw and when, and keep any dated photos, videos or neighbor reports. A public adjuster can match your address to the storm reports.

What Size Hail Damages a Roof?

Hail around 1 inch (quarter size) is the size most often cited as the point where asphalt shingle damage becomes likely. Older roofs and brittle materials break with smaller stones. The October 2026 storms produced 1- to 2-inch hail in parts of Mesa and North Phoenix, which is well into the range that damages most Arizona roof types.

Here is what Phoenix-area roofers were finding after this storm, and what to look for on each roof type:

Asphalt shingle roofs. The hardest hit, according to East Valley contractors. Look for dark bruises where granules are knocked off, soft spots that give under light pressure, cracked or torn shingles, and granules collecting in gutters and at downspouts.
Clay tile roofs. Clay is more brittle than concrete and took damage in this storm. Look for cracked, chipped or broken tiles, especially on ridges and hips. Cracked tile exposes the underlayment, which is the roof’s real waterproofing layer.
Concrete tile roofs. Generally held up better, but look for chips, corner breaks and hairline cracks. Even a few broken tiles can mean the insurer owes for underlayment work if the tiles cannot be matched.
Flat foam (SPF) roofs. Common on Phoenix homes and commercial buildings, and damaged in this storm. Look for punctures and fractures in the elastomeric coating. Once the coating is broken, UV breaks down the foam.
TPO, PVC and modified bitumen commercial roofs. Hail bruises single-ply membranes in ways that are often invisible from a walk-around. These need a close inspection with each strike marked. See our commercial hail claim guide.
Metal roofs. Dents on panels, ridge caps and flashing. Whether a policy pays for “cosmetic” dents depends on the policy’s wording.
Rooftop solar. Cracked panels and damaged racking. Contractors recommend having solar systems checked after this storm.

Hail damage is not just the roof. Check AC condensers and rooftop package units for bent fins, window screens and sliding door frames, stucco and painted surfaces for spatter marks, skylights, patio covers, fences, carports and vehicles.

Some roof damage takes time to show. A cracked tile or bruised shingle may look fine from the ground and start leaking at the next rain.

How Do You File a Hail Damage Insurance Claim After the October 2026 Storm?

Step 1: Document the damage now

Photograph and video every side of the building, every roof slope you can safely see, the AC units, windows, screens, vehicles and any interior leaks. Include something for scale next to hail marks. If you saved hailstones, photograph them next to a ruler. Write down the date, time and what you saw. Do not climb onto a wet or damaged roof.

Step 2: Prevent further damage

Your policy requires reasonable steps to protect the property. Tarp open areas, board broken windows and move belongings away from leaks. Keep every receipt. Reasonable emergency repair costs are usually part of the claim.

Step 3: Report the claim promptly

Call your insurer or file online and get a claim number. Give the date of loss and a short, factual description such as “hail damage to roof, windows and AC unit.” Do not guess the roof’s age, speculate about earlier damage, or describe the damage as minor before it has been inspected.

Step 4: Get your own roof inspection for hail damage

Before the insurance adjuster’s visit, have a licensed roofer or a public adjuster inspect and document every slope. After a large storm, out-of-state “storm chaser” crews arrive quickly. Check that any contractor holds an Arizona ROC license, and read any contract before you sign it.

Step 5: Be there for the insurance adjuster’s inspection

Walk the property with the adjuster and point out every damaged slope, soft metal, AC unit and exterior item. Ask them to note test squares and hit counts. Get the estimate in writing and compare it line by line with your own.

Step 6: Push back on a partial repair

The most common hail underpayment is a partial repair, or “spot repair,” when the damage or the inability to match materials calls for a full replacement. Others are high depreciation, missing line items and leaving out code-required work. Read how recoverable depreciation works in Arizona so you collect the holdback after the work is done.

How Long Do I Have to File a Hail Claim in Arizona?

Your policy requires prompt notice, so report the damage within days of the storm. Arizona law lets a property policy limit lawsuits against the insurer to one year from the date of the storm (A.R.S. § 20-1115), unless the policy gives longer. For this storm, that means October 20 or 21, 2027 is the outside limit, and you should act well before then. See our full guide to Arizona insurance claim deadlines.

What Is a Wind and Hail Deductible?

Many Arizona policies carry a separate wind and hail deductible, often a percentage of the dwelling or building limit instead of a flat dollar amount. On a home insured for $400,000, a 2% wind and hail deductible is $8,000. Commercial policies commonly carry 1% to 5% per building. Check your declarations page before you assume the claim is too small to file.

Commercial Buildings, Apartments and HOAs Hit by the October 2026 Hail

The storm crossed some of the Valley’s densest commercial corridors, including Mesa, Chandler, Tempe, North Phoenix and Glendale. Commercial hail claims are larger and harder than homeowner claims:

Percentage deductibles per building can make the deductible tens of thousands of dollars, so the scope has to be complete.
Coinsurance can reduce the payout if the building was insured for less than the policy requires.
Business income and extra expense may pay for lost income, continuing expenses and temporary space while the building is repaired, if the policy includes it.
Ordinance or law coverage can pay for code upgrades the repair triggers.
Multiple buildings on an apartment complex or HOA each need their own documentation.

Property managers and building owners can read our commercial property hail damage claim guide and our commercial claims service.

Churches and Houses of Worship Hit by the Hail

In Mesa, the pastor of Grace United Methodist Church told FOX 10 the October 20 storm knocked down an outside wall and toppled several 40-year-old trees on the property. Churches face their own claim problems: steep and multi-level roofs, stained glass, steeples and bell towers, multiple buildings such as a sanctuary, fellowship hall, school and parsonage, and a board or committee that has to approve decisions. See our church and house of worship insurance claims page.

How a Public Adjuster Helps With an October 2026 Hail Claim

The insurance company’s adjuster works for the insurer. A licensed public adjuster works for you. We inspect every slope and exterior item, build an independent estimate, document the storm date against NWS data, handle the paperwork and phone calls, and negotiate the settlement. We are public adjusters, not attorneys.

If the October 20 or 21 storm damaged your property in Mesa, Chandler, Gilbert, Tempe, Scottsdale, Phoenix, Glendale or Peoria, book a free hail roof check or request a free claim review. If your insurer has already made an offer, we can review it against the damage before you accept.

Frequently Asked Questions

When was the Mesa hail storm in October 2026?

Tuesday night, October 20, 2026, between about 10:05 and 10:25 PM. NWS storm reports show hail from Chandler and Gilbert through Mesa, up to 2 inches east-northeast of Mesa. A second storm hit North Phoenix, Deer Valley, Glendale and Peoria on Wednesday afternoon, October 21, between about 3:25 and 4:05 PM.

What is my date of loss for the October 2026 Arizona hail storm?

East Valley properties (Mesa, Chandler, Gilbert, Tempe) most likely have an October 20 date of loss. North Phoenix, Deer Valley, Glendale, Peoria and Carefree most likely have October 21. East Mesa toward Usery Mountain and Fountain Hills had warnings on both days, so check the storm reports for your location.

What size hail damages a roof?

Hail around 1 inch and larger is commonly cited as the point where asphalt shingle damage becomes likely. Brittle and older roofs can break with smaller stones. This storm’s 1- to 2-inch hail can damage shingles, clay tile, foam and single-ply roofs, AC units and windows.

How long do I have to file a hail damage claim after the October 2026 storm?

Report it promptly, within days. Arizona law lets a property policy limit suits against the insurer to one year from the date of the storm (A.R.S. § 20-1115) unless the policy gives longer.

Do I need a roof inspection for hail damage before I call my insurance company?

You can report the claim first and still get your own inspection before the insurer’s adjuster visits. An independent inspection gives you a record to compare against the insurer’s estimate.

Can a public adjuster help with a commercial building or church hail claim from this storm?

Yes. Commercial property policies carry percentage deductibles, coinsurance and business income terms that are more complex than a homeowner policy. A licensed public adjuster documents the loss and negotiates the claim for the property owner.
