Dangers of unpermitted roof when reselling properties

[Eli Silverman]

I have a house I'm looking to wholesale but I have a concern about the roof.

It was replaced a couple of months ago and the seller thought that the roofers were pulling permits but I can't find any evidence of permits being pulled on my city website.

The roof was a tear off and a secondary moisture barrier was installed underneath. It's 3 tab shingles not architectural. She says she monitored the installation to make certain everything was too code.

My question is, how much if any headache will it be reselling the house if permits were in fact never pulled. What will it cost to mitigate the issue.

Can a buyer get insurance if the roof was done without permits? 

I live in Jacksonville Florida if that makes any difference.

Thanks in advance

Thanks
