My house is hot in the southern United States. Trying to add insulation in the attic space during the summer almost killed me last year. The attic was so unbelievably hot. I have developed a roof leak and was thinking about a metal roof on top of my current roof. I was wondering why a metal roof can’t be installed on braces a few inches above an existing roof to function as a roof and shade. The airflow between the two would have to cool the attic, much better than if the heat radiated through straight to the shingles and plywood. We bought a sunshade for our back patio, and I’ve thought about even something as simple as that over smaller homes could drastically help.

That’s what the attic is for. Ideally it is vented to that the heat rises up and out, either through a ridge vent or windows in the attic, and pulls cooler air up through the soffits.
The attic gets hot so that your living space doesn’t. That’s why you put insulation in the floor of the attic/ceilings of the living space, and not along the roof.
