Okay I live in South East Texas.... Going to put a metal roof on my house I am doing all the work. so I am looking for the best cost effective way to install it... It's gonna be r panel....should I put solid decking the an underlayment then screw the tin straight to the decking......I freind said I can put purlins down and put foam between them and not worry about an underlayment.... He said that how he was taught to do it in school. I also plane to insualte the celling joist...and a have a vented Attic.

If you have a properly vented attic, I suggested solid decking, underlayment, and the metal roof. Let me know if you do not have a vented attic and we can discuss options. Your area can be prone to condensation so I took that into consideration with my recommendation.
