Eric I am wanting to add a galvalume metal roof to my home. My question is also about insulating between the shingles and the metal roof. I'm getting different opinions from contractors on the insulation. Some say it isn't necessary others say it is. I live in south Louisiana and don't know which way to go to insulate or not to insulate?
What is the construction of your existing roof right now? Sealed attic construction or vented?
If its vented, and vented well, the insulation is mostly going to serve as a leveling substrate in that case.
Thank you for the advice!!!
