Searching for aluminum coil for new roof
I have a few RV projects in the burner. One involves needing about 25’ of 96” wide .004” aluminum. My Google fu has been weak. I have found multiple places that advertise it online without listing ...

I don't think there is anyone stateside that rolls .004, or anything else, any wider than either 60" or 72".
I remember when hanging out for years at popup forums many tried to find 96" wide for rebuilding popup roofs, and I don't believe anyone ever found it. They always had to figure out a way to seam two pieces together.
Handling .004 is going to be very difficult without kinking or tearing ! Regular household aluminum foil is .063 and the HD foil is .094. I think I would want at least .1 or .125
As for seaming, depending on the substructure, you could just lay the first sheet down, lay a 1" strip of butyl tape on the edge, lay the second sheet and screw down with stainless/aluminum screw with washer heads and rubber gaskets.
There are a lot of different alloys of aluminum plus several different types of heat treating. Someone smarter than myself will have to answer which is best.
