Metal roof with exterior fasteners OK for school?

My school board is discussing a new roof for our building. We recently insulated our attic space and want to prevent any possible ice dam water infilitration with our new roof.

It was suggested that we look at using, ice/snow membrane adhered directly on the roof deck followed by 1-in. strapping -- installed vertically -- and then agricultural type metal roofing (exterior fasteners) to finish. The idea being that the membrane would be the primary defense on moisture entering the buiilding and the metal roof would be ventilated by the air space from the strapping to provide a truly cold roof.

We are in mid Vermont in a relatively snowy location.

We are looking for comments.
