I am wanting to put a new metal roof up starting from scratch (trusses will be here next week) and have got a different opinion on how to install it from everyone I ask. I understand there are two main issuses that need to be prevented. That is the fastners pulling out and sweating. This is what has been suggested the most. 3/4 plywood. tar paper. foil faced bubble wrap. furring strips. metal panel. There seems to be some disagreement about where the foil bubble wrap goes and also whether or not to use the furring strips. Does anyone have any usefull info here? Who has a roof that has been installed for a long time without issues and how was it done?
