Insulation next to metal

I'm building a small place,using a 18◊30 metal carport
I placed my insulation directly next to the tin. I have just started to notice condensation. Am I going to have pull all this down and put some sort of vapor barrier,and if so what would be my best options
Thank you
God bless

Welcome to the forums.

A car port is just a roof for protecting cars from the weather.
How are you building a small space ?
What are the walls ?

What you are describing sounds like it will be hard to insulate.

There should be an air space between the tin and the insulation.
I am assuming this is the roof and the insulation is fiberglass.
Also there should be the ability for air flow in the air space.

A vapor barrier goes on the warm side of the room so it should be tin - air space - insulation - vapor barrier.

If this is a car port re: no w2alls I do not understand why you are insulating it or how you can get condensation on the tin.
More info is needed!!!
