Oh, no!! I'm sorry.
An ice dam in the attic after one horrible snowstorm caused a similar problem with me. I opened my bedroom door one day to find water pouring all over my desk. Fortunately, my computer wasn't on it, and, actually, hardly anything else was, either, so nothing got damaged. Still, it ruined the wallpaper, left stains all over the ceiling, and gave me quite a lot of cleaning up to do.
