At your elevation of 6500 ft, I would assume it to be from Ice Damming contributed from high winds during non-winter months.

Got an overview picture from further back including the elevation of the home?

Yes I agree and refer it to as pull-out of the fasteners. Here is a very good article by Internachi on Fasteners that you can pass on to your clients.

Thanks for the input! It never hurts to have a second opinion.
