Download, burn and boot a copy of GParted-Live[1], which is a live-cd for GParted,
the partition manager. Use that to shrink your, say, home partition and
grow your root partition.
Another alternative, if you need minimal downtime and you can unmount
hour home partition is to shrink that, create a second root partition
and copy everything onto that, adjust grub to boot the new root
partition and then delete the old one and grow your home back into the
recovered space. In other words:
[--- root ---] [--------------------- home -----------------------]
[--- root ---] [------------- home ------------]
[--- root ---] [------------- home ------------] [--- new root ---]
*** Reboot ***
[------------- home ------------] [--- new root ---]
[----------------- home -----------------------] [--- new root ---]
