Bob, you were extremely fortunate that more wasn't damaged by the rain and the collapsed roofing.
I agree with all everyone that stated to dry them out thoroughly and remove the batteries immediately. Check each item individually.
Maybe even using a hand held hair drier to blow hot air into the those areas you can't get to without a complete disassembly.
Just make certain to move it around so as to avoid any accidental bubbling of paint. Also don't put it on the highest setting. You want warm to hot air that won't damage delicate parts.
Please keep us informed as to what your insurance company ends up saying it will do for you regarding the layout. It may prove to be a good lessen for us all.
