Abstract
A metal roof panel includes a rib with a unique shape. The rib is bilateral with upwardly angled sides that each transition into an indentation, with both indentations transitioning into a central flat apex. Between each rib is a channel, preferably including at least one raised surface. The lower surface of the channel between the raised surfaces, and the top of the raised surfaces, are substantially planar and parallel to the flat surface of the apex of the panel. A unique method of manufacturing the roof panel employs a roll machine configured to shape a piece of sheet metal into the roof panel by modifying the shape in many small increments, which allows the final product to have a fairly intricate bend pattern.
Claims4
A method of installing a metal roof including the steps of:
- A. positioning a roof panel on a roof, said roof panel having a profile including:
- i. a plurality of bilateral ribs having upwardly angled sides that each transition into an indentation, with both indentations transitioning into a central flat apex extending from one of said indentations to the other of said indentations and having a width of approximately ⅝″, wherein said ribs run substantially parallel to the slope of the roof, and wherein the angle formed between one of said upwardly angled sides and said central flat apex is approximately 126°;
- and
- ii. a plurality of channels each positioned between two of said ribs, each channel including at least one raised surface and at least one lower surface, said raised surface having a height of approximately ⅛″, wherein the angle formed between one of said upwardly angled sides and said central flat apex is approximately 54°, and wherein said at least one raised surface and at least one lower surface are each substantially planar and parallel to said central flat apex;
- and
- B. attaching said roof panel to said roof with a plurality of fasteners engaged with each central flat apex wherein the resulting flat apex and fastener interface is substantially impermeable to water, wherein said roof panel is strong enough to withstand wind sway and rib deformation.
