Does backer board have to be replaced when re tiling a bathroom?
I'm retiling my bathroom. I'm removing the old tile and I'm able to do it without completly destroying the back board underneath. Do I have to replace the old backer board or can I just lay the tile on the old backerboard?

You can reuse it if your able to get it smooth enough to except tile and be lumpy. Thin set must be smooth , you can actually add a skim coat to make it all smooth if need be. Any questions you can e mail me thru my avatar PS I m assuming you have a cement backer board, if not properly add a cement board if you have a trim available to do it that way. ( A 4200 or an A106 type trim) If it is a drywall, do your self a favor and cut it out and redo w/ a cement board GL

Answer 2
I personally would replace it to make sure it's flat and also make sure it water resistant type and not regular drywall.
