A steel or even wood deck that will easily accepts fasteners makes a good essence for the mechanically mounted membrane. These techniques may be designed in order to provide the essential resistance to recognized wind forces and are not subject to slope limitations.

Another alternative could be the fully adhered program, in which the particular membrane is linked to the ready substrate using some sort of specified adhesive.
