I would re-punch, just my 2 cents... Use the point on the back of a slaters hammer and I think you'd surprised to find its not that big of a deal. The potential for damage caused by the heads too high is - in my opinion - an unacceptable risk.

I am re-roofing with recycled Peach Bottom slates. The nail holes are counter-sunk, but not widely enough to accommodate the heads of the nails I'm using (the standard copper nails from the online store). Basically the nail head is just sitting on top of the slate as if there were no counter-sinking. However, the undersides of the slates don't seem to show any wear from the previous installation.
Also, I'm mixing in some new slates that were drilled without any counter-sinking.
How big of a problem is this? Do I have to re-punch every single hole to get the counter sinking? Or ream out the counter-sunk area with some sort of masonry bit? If it's something that won't be a problem for 30-40 years I might just not worry about it.
