"The first thing that needs to be done with a building that has survived a flood is to check its structural strength," says Ken Hellevang, North Dakota State University Extension Service agricultural engineer and flooding expert.
"If the building has been moved, shifted or twisted, it may not be safe to enter. Check the foundation, sill, plate, roof supports and walls for damage. If there is extensive damage to the building, it probably will be less expensive to tear it down and start again with a new building, as compared with attempting to repair the damaged structure."
A rule of thumb is that if repairs and restoration cost more than 60%, building new usually is best, he says.
