leaky roof?

 I was a homeowner for many years so I am familiar with leaky roofs.  However, now I live in a tenth floor apartment with four more floors above me so I was not expecting leaks in my ceiling.  Actually, about four years ago I did have a ceiling leak but that was in my bathroom and caused by a plumbing problem in the bathroom above mine.  Happily everything was fixed, good as new.  This week, however, on Wednesday when we had lots of wind and rain, I discovered a leak in my bedroom ceiling.  The water trail started at the angle between exterior wall and ceiling and extended for about two feet into the room.  Since it was late at night and not what I would consider an emergency, I put a couple of waste baskets under the leak and put a towel over them so I wouldn't hear the annoying drip drip all night.  In the morning the towel was quite soggy but the rain had stopped and nothing was dripping any more.  I called the office to report the problem and a maintenance man came by today to have a look.  When he saw where the problem was (the young lady I had reported it to had told him it was a leaky window) he told me that they had received several reports of similar leaks since Wednesday.  I didn't find this particularly reassuring.  Is the whole side of the building going to start leaking like a sieve?  But he reassured me.  A company has already been hired to reseal all of the ledges and other places where water could get in on the north side of the building.  This should be interesting to watch.  Stay tuned.
