Replacing my garage roof

I currently have a single concrete garage, prefab type with an asbestos roof. I get really bad condensation over those really cold winter days, and as I park my car in there, I am looking at replacing the roof. I have done lots of research, looked at loads of forums, etc.
But there just seems to be so much opinion that I am struggling to decide what to replace it with.
The roofer near to my house said to install a Vermont slate roof.
My Gf's brother suggested polycarbonate transparent sheets.
My colleague suggested a steel sheet.
The garage currently has lots of ventilation, but the walls are obviously not breeze block. Any advice/recommendations appreciated, sorry if this topic has been covered before.

Cheers!

You need more ventilation in a concrete structure. The block can soak up the moisture so it takes more time to get out. Really dosnt matter what roof you have. Shingle would not be my first choice in this case.

Is neighborhood conformity or resale an issue?
Around here, a composite (shingle) roofs has a lifespan of under 20 years, due to hail. Steel is by far the best option - but I'm 1400 miles away...
Any roof can be vented - or if you insulate with foam or similar, that may change things.
