why can’t homes or buildings have a sunshade or second roof above them to shade the buildings and cut cooling costs.

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.

They are called trees.

Just kidding. I know that is not possible everywhere. But create a shady dry spot over your rough and you well have animals living up there in no time.

Although as I type this I had a brick house in So Indiana that the bedroom wall faced the setting sun. The brick would heat up and radiate heat into the house all night.

I started hanging 3 10×10 silver tarps from the eaves on sunny days and it made a world of difference.

Good idea. You just have to pick the right method for your property
