Threshold markers:

• Water is over 3 feet high on the first-floor level of the house
• Significant damage to exterior walls
• Significant damage to the main portion or multiple sections of the roof framing

Common damage:

• Missing exterior wall(s) or open damage to large portions of the wall structure
• Wall studs and sheathing damaged by contact, collision, or piercing with debris or from floodwater pressures against the structure
• Large missing or damaged sections of the roof structure
• Significant deformation or distortion of the structural frame is evident

In a home that is damaged between 75% and 100%, there is generally full-scale damage to the frame of the home that may have caused the entire structure to collapse.

As the photo shows, in these cases, it may be difficult to discern what the original frame of the house looked like prior to the damage due to the deformation of the walls. There will likely be major damage and possibly complete structural collapse.
