Standing seam roof and method of manufacturing same

In a building structure, the combination of a plurality of spaced supporting members, a series of rigid interlocked metal panels affixed to and enclosing the space between said spaced supporting members, each of said panels having a central web with first and second side edges, a side wall connected to and projecting upwardly from each side edge of said central web,

• a first said side wall comprising:
• a first vertical leg and a first base member connected to the upper end of said first vertical leg and having an outer edge located over said first side edge, a nail strip flange in the same plane as said central web connected to the bottom of said first vertical leg,
• a second vertical leg contiguous to said first vertical leg, said second vertical leg being connected to a second base member having an outer edge located over said first base member and a connection between the edges of said first and second base members,
• said second side wall comprising a third vertical leg with an upper, inverted U-shaped channel formed from a base member having one edge connected to the upper end of said third vertical leg and another edge extending outwardly beyond said second side edge and having a vertical lip member connected to said edge,
• said side walls being dimensioned so that the inverted U-shaped channel on one said edge fits on and interlocks with the base and first and second vertical legs of the first side wall of an adjacent metal panel.

A method of coupling together and simultaneously forming a continuous rigid waterproof joint between the adjoining and upwardly projecting side walls of a pair of channel-shaped panels formed of a central web having first and second side edges, said joint extending along the entire length of said panels, wherein the first side wall of one panel comprises a first vertical leg and a first base member connected to the upper end of said first vertical leg and having an outer edge located over said first side edge, a nail strip flange in the same plane as said central web and connected to the bottom of said first vertical leg, a second vertical leg being connected to a second base member having an edge located over said first base member and a connection between the edges of said first and second base members, and wherein the opposing side wall of the other panel is comprised of a vertical leg with an upper, inverted U-shaped channel formed by a base member having an edge extending outwardly beyond said second side edge and a vertical lip, said method comprising the steps of:

• a) locating a panel with said nail strip flange positioned in an orientation to overlay a roof supporting surface into which fasteners may be secured,
• b) driving fasteners through said nail strip flange into said roof supporting surface,
• c) placing the second side wall of an adjacent roof panel into engagement with said first side wall wherein said inverted U-shaped channel is interfitted over the base and first and second vertical legs of said first side wall, and
• d) placing pressure-applying means against said side walls and effecting a seaming deformation thereof whereby said lip is deformed to a position lying directly beneath the first base member on said first vertical leg.

A method of coupling together and simultaneously forming a continuous rigid waterproof joint between the adjoining and upwardly projecting side walls of a pair of channel-shaped panels formed of a central web having first and second side edges, said joint extending along the entire length of said panels, wherein the first side wall of one panel comprises a first vertical leg and a first base member connected to the upper end of said first vertical leg and having an outer edge located over said first side edge, a nail strip flange in the same plane as said central web and connected to the bottom of said first vertical leg, said nail strip flange defining a plurality of nail holes along the longitudinal length of said panels, a second vertical leg being connected to a second base member having an edge located over said first base member and a connection between the edges of said first and second base members, and wherein the opposing side wall of the other panel is comprised of a vertical leg with an upper, inverted U-shaped channel formed by a base member having an edge extending outwardly beyond said second side edge and a vertical lip, said method comprising the steps of:

• a) locating a panel with said nail strip flange positioned in an orientation to overlay a roof supporting structure into which nails may be driven,
• b) driving nails through the holes of said nail strip into said roof supporting structure,
• c) placing the second side wall of an adjacent roof panel into engagement with said first side wall wherein said inverted U-shaped channel is interfitted over the base and first and second vertical legs of said first side wall, and
• d) placing pressure-applying means to said side walls and effecting a seaming deformation thereof whereby said lip is deformed to a position lying directly beneath the first base member on said first vertical leg.
