While, technically, not using decking would work, it creates a real mess if and when the roof has to be removed. Also, generally, I prefer closed cell. If moisture migrates through the foam, it will condense on the back side of the roofing / roof decking, which is not a good thing. I hope this helps.
We are building a new home. We live on the north of Lake Pontchartrain in Louisiana. We are trying to be as cost effective in order to build our dream home (actually doing a lot of the work ourselves). It will be a straight gable roof.
My question is about best vs minimum installation practices.
Thanks,

There are several benefits to metal roof & they are last a long time. Metal roofs are cost-effective, especially when considering the durability.
