In central Texas, where I live, tend to agree on that, especially the attic
area. You don't want the attic sealed up as it won't vent the heat, very
important especially in the summer. Found the ridge vent system with an
adequate number of soffit vents works better than the typical gable vents.
Even when using fan aids in the attic with gable vents.
I am confused about the metal roof question though. I thought the
insulation for that type of roof was placed between the rafters and the
material the metal roof is attached to. Something like Thinsulate for
instance.
