Hello Everyone, I would like to know if there is anything special I need to do when putting tile on the ceiling above a woodstove. :p

Depends more on what the codes in your area say.
You might need an insulated pipe, metal studs, ventilation behind the cement board.
But if this is an existing stove then you're probably already up to code so all we need to know is ... what's the existing surface and how large are the tiles?
