How roofing engineers tell hail damage from wear on shingle and tile, the East Valley hail record, and how we document damage for your claim.

Hail damage has to be confirmed on the roof, not guessed at from the driveway. On shingles, roofing engineers say hail has to puncture or fracture the shingle to count as damage. On tile, hail breaks usually spread out from one impact point. If hail hit your area, stay off the roof, write down the storm date, take photos from the ground, and book an inspection. Our team will document what we find. Your insurer or agent answers the coverage questions.
The National Weather Service defines large hail as hail greater than 1 inch across. It also says small hail driven by strong thunderstorm winds can cause damage.
Engineers writing for the National Roofing Contractors Association (NRCA) list rough hail sizes at which damage starts on new roofing:
| Roof type | Hail size where damage can start |
|---|---|
| Three-tab asphalt shingles | 1 inch |
| Laminated (architectural) shingles | 1¼ inches |
| Clay tile | 1½ inches |
| Concrete tile | 1¾ inches |
Treat these as starting points, not rules, and have the roof itself checked.
Yes, though it varies a lot by city. NOAA's Storm Events Database lists these hail reports from 2016 to July 2026:
Hail isn't only a monsoon problem. The Weather Service sets monsoon season as Jun 15 to Sep 30. Yet 42 of the 98 Maricopa County hail reports from 2016 to July 2026 came in October and November. Those 42 reports came from just 12 storm days, so one fall storm can produce a lot of reports. Still, it's a good reason to check your roof after a fall storm too.
You can look up storms near you in the NOAA Storm Events Database.
The NRCA article, written by an engineer at Haag Engineering, lays out what counts:
Look for spatter marks, too. These are spots where hail knocked dirt or oxidation off metal vents and other surfaces. The NRCA article says they typically linger for about a year, so they can help show when a storm hit.
Tile damage reads differently from shingle damage.
The Tile Roofing Industry Alliance (TRIA) says broken tiles usually come from large hail or flying debris such as tree limbs. A broken tile doesn't by itself prove wind lifted the tiles. TRIA also notes that underlayment that hasn't been exposed to the weather will likely keep shedding water, even under older tile. And it says new or reused tiles should not be put back over damaged underlayment.
One more thing to know: TRIA says repaired tiles usually won't match the old ones exactly, because tile changes color as it ages. Ask your insurer or agent how your policy handles that. We can't tell you.
Yes, we do foam roofing. If you have a flat or low-slope foam roof, we inspect it after hail the same way: up close, with photos of what we find.
You file the claim with your insurer. We handle the roof side:
On storm jobs paid by insurance, Arizona law (A.R.S. 32-1158.02) says the contractor's estimate has to show the damage found and where it is, the square footage, any areas left out and why, and whether the contractor went up on the roof. Ours does.
We can't tell you what your policy covers, promise approval, or promise anything about your deductible. We don't negotiate or act as your adjuster.
Arizona's contractor law has a few rules for storm repairs paid by insurance after a catastrophic storm. A roofer can't:
Check any roofer's license at roc.az.gov. Ours is AZ ROC #345156. Anyone paid to adjust your claim must hold an adjuster license, which you can check with the Arizona Department of Insurance and Financial Institutions.
We can't tell you that, and no roofer should. It depends on your policy, the cause of the damage and your insurer's decision. Ask your insurer or agent. We can document the damage.
Check the NOAA Storm Events Database for reports near you. To know what happened to your own roof, book an inspection.
No. On storm repairs paid by insurance, Arizona law says a contractor can't pay, promise to pay or rebate your deductible.
Yes. We do foam roofing, and we inspect foam roofs after hail.
If hail hit your home in Mesa, Chandler, Gilbert, Queen Creek or Apache Junction, start with an inspection. We'll document the damage and explain your roof's condition. We also serve the rest of the Valley and as far south as Tucson.
Book an inspection with us or call (602) 806-6806. We answer 24/7. See also our tile roofing page, our Chandler roofing page, and what a roofer can do after monsoon roof damage.
