Condo association refuses to pay for water damage caused by neglect

I live in a small condo complex (24 units) in New Jersey. Last February I had damage in the interior of my condo because of a leak. A roofer came and assessed that the damage was probably caused by clogged gutters. At the time, I was informed that the gutters had been cleaned and that I could go ahead with the repairs within my unit and that if the leak should return that the complex would pay for any interior damage. Last week we had heavy rain and the leak returned once again causing damage to my wall. I informed the maintenance company and asked that they send someone over to repair the damage. I was informed that over the summer a letter had gone out to unit owners explaining that because of a tight budget the complex would no longer be responsible for interior damage caused by leaks from the roof. Is this legal? Can they force me to enter into a cycle of constantly having to repair damage inside of my unit which is cause by clogged gutters that they should be maintaining?
