I was thinking about buying a cheap core drill so I could insert 2" galvanized pipe into the ledge rock we have around here and inserting PVC inside that to make a hoop roof and shrink wrap it.
In the boat yard people use pairs long lengths of 1x3 with 2x 4 spacers to make curved structures and the wrap it in clear plastic. Winter temps are warm when it is sunny and in the summer tarp are used to block the solar
heat gain. I might build something like that as I need more covered storage.
