Yes, I agree the world would be a much better place if people did not take plans made on the back of an envelope and scale them up to mass production before they had any real world experience.
Below is my back of the envelope drawing. The top of the Figure shows the interweaving panels. There would need to be no exposed nails or fasteners of any kind. The panels (purple on top of the red rectangles) would be on the tracks ( blue tracks attached to the panels correspond to the red rectangles attached to the blue plywood on the roof) shown at the bottom of the Figure. They could be designed so that they could be tightened or loosened as needed (see the bottom most drawing in the Figure).
I am not sure though thermal expansion might be tolerated on the ends or also with a bend in the middle.
With this idea you could have attachment of the panels over all or most of its length. At the bottom you could have additional
of the fasteners (red rectangles) to give a very solid and secure seating. At the top, you could always have some pre-drilled holes for screws that would be underneath the ridge cap which might also use these unexposed fasteners.
I also believe in sticking with the tried and true. No one in our area has anything other than asphalt.
Yet, I am disappointed in what has happened with the latest shingles.
I have looked into a large range of roofing products. I even gave some consideration to the Tesla solar roof.
It appeared to be a very solid product, though when I realized that we would need a mortgage to pay for the $100,000
expense, I reconsidered.
One other roofing idea that I have had is a roofing foam that could be applied over the shingles.
Our latest shingles have been “caked and baked” in the heat.
A product that could remove the extreme summer heat off the roof would be so great!
It would not need to waterproof; all it would to do is absorb the heat of the sun.
Something like a mesh covering.
