Lowes has Ondura roofing, and it is pretty cheap too. It looks like corrugated metal roofing, but it's not. It is actually a tar paper/composite type material. Supposed to last a long time, and comes in different colors. Our Lowes carries it in red, white and tan. Looks easy to cut and install too- says it holds up longer/better than shingles. Much cheaper than shingles, too. I've noticed a LOT of coops on here have Ondura roofing. A panel costs about $19.
