Why is it that you can add structural deck to a floor system but not to a roof system?  I am in Revit Architecture 2012.  I know that I could go in and put my 1 1/2" metal deck as a floor system for my roof then add the insulation right on top of it as a roof system but I wan't sure if that would have any repercussions in the long run.  Has anyone delt with problems in doing it this way or is there a better way?  I know I can just use detail components to fill in a section view but why would I when I could have it built right into the system.

Good point.

I have no idea why the software will not allow "Structural Deck" as a "Function" in the Roof type.

You have to make it a Floor instead.

Very confusing and makes no sense. Anyone ?

Then you have Roofs that are actually "Category" "Floor" which must be made aware of for visibility and quantifying etc. . .

I'm not sure whether it has something to do with some terminology. Deck is always considered a floor with live load due to activity and never considered the roof of the lower floor (though it does seem like that). A roof Live load is always considered predictable from equipment. If you know it's a deck, then you use the floor to model. If it's a roof, you can do a similar deck profile but it has to be a roof component. I guess!
