My roof is leaking. When it is raining hard my roof leaks a lot. I told my landlord and super many times. They did something couple times. It got better and then it started to leak again. Sometimes it leaked up to 3 liters a day. Couple times my PC and printer and my papers got all wet. What should i do? I mean they were doing something but that didn't improve my situation. I am living on the top floor.
