Anyway,like was mentioned,if this isn't your building,the owner is responsible for not just the roof repairs but your plaster repairs(most likely,as they have to provide a secure building to be able to rent/sell living space)
I ask about the style because some fasteners break down differently in different locations,Slate have been installed with copper nails for many generations being that slate LASTS,,but once the nails fail and tiles begin to crack,,it's time to replace the roof system..
Spanish tiles on a pitched roof can be repaired by alternate methods,but the same applies,once things begin to deteriorate,the system needs an overhaul.
Hope this helps.
