My dad, as part of his recent farmyard clean up, offered some tin roofing he had left over from building his barn years ago. Of course I’ll take it! Free tin roofing. Sweet. We were planning on putting a tin roof on the chicken coop anyway. He even gave us a bunch of tin roof screws (the ones with the rubber washers on them so they’re waterproof). Total cost of roofing the coop: $0.00! Just a little elbow grease.
