Try -F. Quoting tail(1):

  -F      same as --follow=name --retry

  --retry keep trying to open a file even when it is or becomes
          inaccessible; useful when following by name,
          i.e., with --follow=name

  -f, --follow[={name|descriptor}]
          output appended data as the file grows; -f, --follow, and
          --follow=descriptor are equivalent

Though I prefer and have used the shell loop approach to solve this problem.
