My coop is made of PVC and it has a tarp roof. This might give you some ideas. You probably could pound some fence pegs in the ground and tie a tarp over it................But chickens won't hang around under it unless it is under a tree or shady area. I had to train my chickens to sleep on the perch. I let them out during the day and they go back in when it gets dark. I close it at night, so they don't get eaten by a big cat or stray dog.
They never hang out in the coop during the day, they will only go in to lay their eggs. I collect around 7 eggs a day.
They prefer to hang out under my shady Lychee tree. They won't go in even if its raining, they would rather play in the rain. Furthermore, my chickens like to burry them selves in the dirt and take sun baths. They don't like to be held, but they will follow me around and help me pull weeds.
