What happens if inspection shows roof repair, but no permit?

Does this affect an as-is contract? Are all short sales as-is? Will I be fined for not having a permit when repair was done years ago by the seller? Or can this affect insurance premium if damage occurs and insurance inspector sees previous repair was done?
