Claim 0:
1. A roof system, comprising:
a deck having a slope of at least 2:12;
a plurality of metal roofing panels configured to be installed along the deck;
each metal roofing panel comprising:
an upper surface;
a lower surface;
a plurality of peripheral edges, including an upper edge, a lower edge, and side edges;
wherein the upper and lower surfaces of the metal roofing panels along each of the side edges are substantially flat;
at least one sealant or adhesive region positioned on the upper surface and adjacent at least one of the side edges; and

an underlayment positioned between the deck and the metal roofing panels;
wherein the metal roofing panels are installed on the deck with a side edge of a first metal roofing panel overlapping a side edge of an adjacent metal roofing panel in a same course of metal roofing panels, with the lower surface of the first metal roofing panel lying substantially flat against the upper surface of the adjacent metal roofing panel, and with the upper surface of the first metal roofing panel along an entire length of side edge exposed to an external environment; and
wherein the at least one sealant or adhesive region of each of the metal roofing panels is disposed along a region of overlap between the lower surface of the first metal roofing panel and the upper surface of the adjacent metal roofing panel overlapped thereby, such that at least one sealant or adhesive region of the adjacent metal roofing panel is positioned between the lower surface of the first metal roofing panel and the upper surface of the adjacent metal roofing panel so as to attach the lower surface of the metal roofing panel to the upper surface of the adjacent metal roofing panel and restrict migration of water therebetween.
