Not sure, correct me if i'm wrong but don't you need p p for a pitched roof , as opposed to a flat roof ? Polycarb' is ok if it is sealed. It is important to get some sort of inner skin up and a small heater to keep it warm. An air vent is important to in a utility room. In the long run it will work out cheaper to do a proper job and save on utility bills.
