Does the insurance cover things like this?

I hope you don't make a decision like that based on something posted here. The proper answer is: "Ask her insurance provider" All policies are not identical.

No they are not, but a "standard homeowners policy" does not cover it.
If she is covered she has purchased extended coverage at (significant)
extra cost.
