I was looking on line came across future steel buildings and found a roof that went over ccans. Perfect size to cover the ccans and leave covered room to work under as well. I talked to Ryan who was very helpful, I was able to order on line and trust what I was getting. They even changed the roof so I had the option to have a ccan inside or out side of the ccan on one side. If I need a building or another roof I would go with future steel buildings again.
