I'm from PA, but am in NC now. I never saw tin roofs up North, but everyone uses them for any outbuildings down here. I know they're cheap b/c I just replaced the tin roof on the ancient chicken coop that came with our new house (attached to the 100+ year old tobacco barn, but not nearly THAT old. lol) Anyway, just wondering what others thought of them and what their pros and cons are. Cheap is definitely a pro. Why aren't they used up North? Just b/c of snow or for other reasons? I have 30 chicks out there under a brooder lamp and have 40 more eggs in my incubator, so I need to get to work on some more shelters. Wondering if tin (I think it's actually galvanized steel) is the way to go or not.
