Two story house with a foot or two of water. Not sure how you get on roof...if you even gave a ladder tall enough. Water would have to be calm if you dont have someone to stablize ladder.but never have tried it.
Coast guard says dont go to roof. Mark it so can be seen wave towels
I was thinking the same thing, but I just posted what the emergency people there put out. If there is a way to bust out from the attic to the roof that would work.
