I would like to know if one can install drywall directly over sealing tile or do we have to install a layer of vapour barrier

Removing the ceiling tiles before installing the drywall is the best way-----

However, if you choose to overlay the tiles(which is a bad plan) no vapor barrier will be needed.

Personally, I would not do this.
But if you do..... 5/8" drywall (required for ceiling) + 1/2" of ceiling tile = 3" screws.

!/2" is ok for 16" centers. If the new USG "ultra-light" 1/2" drywall is available in your area (HD is carrying it around here), it is ok for 24" centers according to the manufacturer. !/2" of tile + 1/2" of drywall + 1-5/8" screws. We use 1-5/8" screws on 2 layers of 5/8" firecode for fire walls. I'd still tear out the tile if it were mine to make sure the framing will support the extra weight. I'm assuming you're going over the old 12"x12" "staple-up" tiles. They're normally attached to 1"x4" strapping that often isn't well fastened to the 2"x framing because the tile is light weight....
