You are correct. But I will reiterate things just so I know I"m on the same page. Will also try to help with the roof depreciation.
What is a "total loss" to the insurance company, is not a total loss to you. The insurance company only insured the structure - not the land. Basically, just to put it in simple terms, you sold the structure to the insurance company, but you still own the land. The cost basis of the land will not change for you.
Here's but one way to deal with the roof in TTX.
Indicate that the roof was removed from service (converted to personal use, I think) on the date of the fire. As you work through the asset you'll come to a screen for "Special Handling Required?". Read that screen to understand why I'm telling you to select YES, then select YES. This way, you will show disposition of that asset without being asked for a sales price. As for handling the remaining depreciation on the roof, I get the impression you've got a handle on that already.
