No, to be quite simple. If the source of the leak is known AND it's not fixable until it dries out, all you'd do is put a 'bandaid' on the problem. My suggestion is that you move OUT of that room and/or cover anything you've left inside of it. At the same time, make sure you Renters Content Insurance is up to date. I would doubt that you'd see 1 cent from the Landlord if the roof caved in and damaged your 'stuff'.
My best to ya and hope this helps.
