Ours can. Our buildings come standard with high-gauge metal roofs and solid framing built to handle real weather. Michigan snow is part of the deal when you live here, and these buildings are designed with that in mind. The Amish builders in the Shipshewana region know Midwest winters just as well as we do.
That said, if you get a particularly brutal stretch and snow is piling up several feet deep on the roof, it's not a bad idea to knock some of it off. That's good practice for any structure, including your house. But under normal Michigan winter conditions, your building will handle it just fine.
