You did not show the permissions on the home directory.  Those are
also considered and are often the source of problems.

  chmod go-w $HOME

It is possible that root has an ssh-agent and the ssh-agent has an
authorized key loaded but the non-root user does not?  That could give
the appearance of what you describe.

  ssh-add -l
  ssh-add -L
