That seems like a poor design for a roof.
It is similar to a SIP used in sticks and bricks homes. The difference being in a S&B they aren't used in what amounts to a flat/very low pitch roofs. Then on top of that channel out the foam for ducting which would weaken it more.
I can easily see this not holding up to the weight of a large snow load especially if the snow is wet or starts melting and refreezing.
I would be curious as to what the manufacturer specs out the snow load rating of their roof design.
