Thanks for the quick reply Dmun.....There is no wood products on the structure so far, but not sure about the roof. I virtually have no heat loss from the oven, so I was thinking of utilizing plywood for the roof and then lay down the clay tile. Or, I could lay down the cement board like the walls, but I thought I read in a thread that screwing down the strips to lay down the tile is more difficult with the cement board. Not sure why, so I am open to any suggestions.

So back to the vent question...sounds like if I lay down plywood, would be smart to vent. If I lay down the cement board, do you still think necessary to vent? There would be no wood products whatsoever.
