[Dhevie Urdaneta]

Hello guys I hope I find answer here so this past weekend we accidentally left the water in our kitchen, we are renting the second floor/attic of our landlord this is a house. Due to what happen this cause our landlord ceiling become week and the water run all the way to the basement and cause the ceiling to collapse. Believe me we are good people we never wish to harm anyone but on this case what should I do as a renter., we don't have renters Insurrance? How this usually resolved. Please I would appreciate any advice.
