1968 Skipper Roof Repair or Replace?

Hi, got up on a ladder today to inspect the roof. I would like to eventually replace the roof but for right now just looking for what I could apply to the roof for a temporary fix for this summer to camp. I'm keeping a tarp on it for now of course. Is there a vendor that sells metal so I could replace roof with one piece so there are no seams? Camper floor plan is approximately 7'wide x 8'long. TIA
