My question is whether ice/water should be able to get up and under a correctly installed new roof.
And/Or--could the ice formations on the siding surface be caused by something other than a roof problem?

A brand-new roof is not going to prevent an ice dam, shingles aren't meant to stop water that is pooling and can't flow down.
You have to prevent the water from forming by making sure your attic isn't warm when you have a lot of ice and snow up there.
