Your condition is not exaclty clear to me.  Do you
have two different levels of sawtooth roof.  Or
are you talking about the upper and lower portions
of one layer of sawtooth roof?

IMHO:  You probably will have to combine both if
you go two level.

BS, EIT,  I'm no expert on snow loading provisions
(though I have shoveled lots of driveways), but I
didn't want you to be left completely out in the
cold.  :)
