A method of stacking and installing prepared roofing schemes into a roofing context. A complete panel assembly is first prepared, thus "unitizing" it, after which a plurality thereof is stacked one on top of the next. The entire stack is raised to above the roof line of the context, then oriented in relationship thereto, and thereafter, settling the bottom unitized roofing scheme in the stack into place in the roofing context and fastening it thereto. The stack of remaining schemes is removed from the fastened installed scheme, the now lowest one placed into its proper position in the roofing context, settled, and fastened. This procedure is repeated as often as necessary, always settling the lowest remaining scheme in the stack first to the roofing context after the stack has been removed from the immediately previously installed scheme.
