I was told if you dump copper sulfate crystal into a tile plugged with roots that it would burn the roots up and clear the tile. That being said, i have tried that a few times and it didn't work at all so I would have to agree with Haleiwa. Only thing i can think of is get someone with a tile jetter with a root cutter end to try and clear it.
