No insulation or barrier

I'm installing galvanized b deck on metal beams spaced 5 feet apart over my garage which is attached to the house. It will be a straight shed with no hip. The bottom and top of the shedded roof will be screen,not sealed to the outside weather with the feel of a covered screened in porch.. the garage has a cement floor there is a washer and dryer in the garage,vented. How much dripping should I expect'? I expect foggy days to be my problem, no snow here..		John Fierro 6/13/2017	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22179/find/
Impossible to say to be honest. If you are concerned, why not incorporate some sheathing or at minimum some vapor impermeable underlayment?		Eric Novotny An informed customer is the Best Customer! 6/14/2017	Share Or copy this URL: https://www.metalroofing.com/spirit/comment/22180/find/
