This house is only 13 years old. We have had pretty heavy rain since the autumn. It has rained pretty hard since very early this morning.

When we woke up, the plaster in the ceiling fell down all over the place in the kitchen area.

What can be wrong with the roof? It's only 13 years old... However, if nothing wrong with the roof, it would not leak at all. What do we do now? Now it is still raining pretty heavy, perhaps continuing for another day or two.... Even if we could find someone to fix it right away, all this rain would make it impossible to do anything at this point. What can we do NOW, and after it stops raining?

Thanks
