Penthouse air intake smoke damper/fire damper?

Hi I have a question.

We are designing a make up air system for a kitchen exhaust for a beach house at Long Island NY.

The air intake is going to be a louvered penthouse at the roof and the kitchen is at the top floor so the only thing the ductwork is penetrating is the roof.

I want to know if I need smoke damper and fire damper at the location where duct does its penetration since the roof is a fire rated.

IBC is really confusing about where is required to have fire damper and smoke damper and I do not have a copy of NFPA 90A.

Can someone help?
