The invention relates to roll forming roofing and walling sheets that have pre-cut or pre-marked ends and packing the sheets. The invention includes applying a particular set of rules to a roll forming schedule produced by a current program, such as an Applicad Roof Wizard program, and producing a roll forming schedule that roll forms sheets in an order that does not require sorting after roll forming but results in sheets packed in a logical order for the person cladding a structure, such as a roof or a wall.
