I had a leak in this location and had a roofer repair this today. Apparently, it was leaking through the exposed nail (pre-fix, 2nd photo). So, I am concerned the fix is going to have the same problem, but times 3-4 - given there are now 3 or 4 exposed nails.

Should I have them re-do it? Or is this a normal install? For pros, how would you rate this?

Thanks!
