First row of shingles removed and replaced during installation
The ice and water, and underlayment was installed (code here is 3′ beyond the finished wall). Everything LOOKED good. Then halfway finished with all shingles up the roof, I saw my contractor remove the first rows of shingles and replace them. When I asked him why his response was there was an issue with row alignment that needed to be fixed. He said he sealed the nail holes after I pressed him that ice and water would not re-seal an open hole, but only around a nail.
How concerned should I be? This is Minnesota.
Thank you,

If you are concerned I would ask someone else to investigate.
Personally I would wait to see if anything happens and contact them again if it does...but they probably wouldn't be interested by then.
Have ice dams been a problem in the past with this home?

It's unlikely that they actually individually sealed the holes, but I wouldn't worry. Self-adhering bituminous membranes are good but not perfect; they are a line of defense.
I do occasionally get an ice dam on the north side. When we get freeze/thaw temps combined with rains, it's almost impossible not to get some ice dams. But overall, I have excellent attic air sealing and insulation, so I have never had anything major or roof leaks due to ice damming.
Maybe I could get the contractor to acknowledge that they had to make a fix during the installation, and if I have problems with that, they will make it right. But yea, it's one of those things where it's done, and it MAY never be a problem, but if it is it's a real pain. It negates most of the line of defense of the ice and water.
I wouldn't say that a few small holes in a 36" sheet "negates most of the line of defense." But if that's how you feel, you could peel up a few shingles and see for yourself whether they sealed the holes.
