That's what I was thinking...If you call your city building inspections and they come out and condemn your apartment then whether your landlord likes it or not your lease is over and if the LL attempted to sue you for rent money after you vacated because city condemns it so NO ONE can live there and you brought to court a copy of the condemnation order the LLs claim would be denied.
...And that they should have funneled the water to a drain (not sure if that's legal) or outside.
I have had roof leaks in the kitchen of an apt. - albeit in Iowa and Texas, not IL. In both cases, I was given a partial refund on rent to cover damages. But those were relatively minor leaks.
