We did that with major hail damage a few years ago. I learned that in a disaster, you should count on everything being junk, and you're lucky if you can salvage anything. We also learned the value of itemized lists.

1500/piece for 20 junk windows I was building a greenhouse with that I dug out of the trash the year before. $250 for a bird feeder because they couldn't find one outside of specialty stores. $40k instead of 10k for a new roof on the shed because it was heavier gauge metal than standard.

Exact replacements can be expensive, but you need to make sure your insurance has 100% replacement instead of adjusted for age or like-kind replacements.

After that experience, we itemized EVERYTHING in the house with make, model, serial number, and color. It was a bitch to get set up, but took the value of our home contents from around 75k to over 250k for exact replacements.

Copies of these records along with our master password for our keepass database are in two bank deposit boxes about 45 minutes apart. For $50/year we can sleep easy.
