From what I've seen, marble size hail really only affects old roofs that are deteriorated. Now, if it is accompanied by 70 mph winds it can do some damage.

If your roof is fairly new, the marble sized hail probably didn't do anything to it.

I haven't found too many roofing contractors (especially the ones that knock on your door) who won't tell you that the roof isn't damaged. For them, it is a numbers game. They hope to find an independent adjuster who gets paid based on the size of the claim and isn't too picky about what he sees. If they get 10 homeowners in an undamaged area to file a claim, they might get lucky and get a new roof paid for.

I was on a claim last week and the guy kept repeating "This place is hammered. These gutters are trashed". Yet he couldn't show me one damaged gutter. There are some really nice roofers, but like all professions - there are some sleazebags too.

Edit to add - I was called and asked if I wanted to go work that storm in your area - but I was already here in Omaha.
