Yeah, like 3" and lot’s of it! Notice there lots of missing granules but no fractured mat that I could see. Hard hailstones flling fast would have exposed mat. One layer of shingles?

Hey Brian,

15,000 posts. Congrats

I’ll be there soon;-)

If that was golf-ball sized hail it must have been blowing sideways to create blemishes that large! Damage looks like it ranges from about 1 1/2" to 3". No?

Exactly, did you read the link I posted Kenton? Over 300 Million in Insurance Claims

In October the Mother of all Hail Storms hit here. Some areas look like it just rained Golf Balls, other areas a mile away, Nothing.

Every InterNACHI inspector should be able to correctly identify and describe hail damage.

Know more than most claims adjusters - Free online video course.

I did Brian, but I wasn’t surprised. Repairing hail damage in the US averages $1 billion a year (Insurance Information Institute).
On April 14, 2006,* a single hailstorm* in Indianapolis caused $1.3 billion in damage. That’s the $300 million… and then a $billion more.

There’s a huge pool of ignorence out there about what is and isn’t hail damage. It’s complicated by the fact that there are so many different types and qualities of roof-covering materials in various conditions, the fact that hailstones carry different impact energy (size, density, velocity, wind-driven, etc.), and that hail damage can have different appearances depending on the combination of these things, and the climate zone and local weather conditions in which the hail damage happens.

The first two of the four “Certified Roof Inspector” video courses that cover all this are being edited now. Two years in the making…



I can not find this info. :smiley:

Here’s one link, Brian. I think it turned out to be more. Included vehicles, too.

The Entire State, as I thought. :smiley:

Big Storm nonetheless.

Multiple Storms across the entire State. :smiley:

Careful. I state it as “impact” damage. I had a home on a golf course one time, and the ball damage to the roof looked like hail damage. I have seen shot gun and bullet damage to homes in rural areas. Baseballs, who knows for sure.

Ooooops! I believe you’re right. Thanbks for catching that Brian. I found this one instead…

                 The Tristate Hailstorm: The Most Costly on Record

Stanley A. Changnon and Jonathan BurroughsMidwestern Regional Climate Center, Illinois State Water Survey, Champaign, Illinois

Abstract The most damaging hailstorm ever recorded moved from eastern Kansas to southern Illinois during an 8-h period on 10 April 2001, depositing 2.5- to 7.5-cm-diameter hailstones along a 585-km path. A classic long-lived supercell storm was the cause of the record hailfalls. The record-large hailswath size, large and often windblown hailstones, and movement over portions of the St. Louis and Kansas City urban areas led to $1.5 billion in insured losses. This tristate hailstorm and other adjacent hailstorms collectively created $1.9 billion in insured losses in a 2-day period, becoming the ninth most costly weather catastrophe in the United States since property insurance records began in 1949.

GEEZ was it softball size

The final tally for the October storm here has not been added up yet.

The 300 million I mentioned was from ONE Insrance Carrier.

Hail More Hail

There are pockets here 30 miles apart that were just nailed. :smiley:
