Insulating a porch roof to create a four-season living space
I live in southeast Nebraska and I would like to turn an east-facing 19 by 8 ft. already enclosed porch with a concrete floor into a 4 season living space. there is no structure above the roof.
I don’t see a way to vent the roof and would like to know if I used R-30 insulation and Reflex-it vapor barrier , with the proper dead air spacing and sealed it so very little if any water vapor could escape to get to the under side of the R-30 insulation , if I would be creating a problem with condensation.
If that type of system would not work can You Folks give me some ideas to avoid any moisture issues.
Thank you very much for your time
