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.

Same reason builders in texas still use single pane windows and put no insulation in the walls. Builders are cheap and there are no codes.
Texas can literally cut its energy usage in half just by making people have double pane windows, R15 in the walls, and R30 in the attic. All house are built like shit in texas.
