1. In a prefabricated roof panel for standing seam roofs and the like;
- a metal sheet, including a generally longitudinally extending roof panel portion having an upstanding seam forming edge along each side thereof which includes a wall formed with an externally facing pocket therein at a spaced distance downward from its upper end above said panel portion, the pocket being spaced downwardly substantially the same distance at each side so that the pockets of longitudinally adjoining such panels are opposed and open to one another;
a pre-applied mastic or hot melt weatherproofing bead disposed in each said pocket and protected thereby, and a reversely bent contiguous wall extending downwardly from the upper end of each wall so that the pocket protrudes toward the reversely bent wall, the upper end of the edge being formed with a bridging portion connecting the two walls.

Abstract
A standing seam roof panel joint assembly for standing seam roofs includes a pair of upstanding seam forming mating walls at the side edges of adjacent roof panels which may be interlocked and embraced by a cap strip. These walls of each panel are formed with opposed complementary pockets located substantially the same distance down from their upper ends, adjacent reversely bent contiguous wall sections which are embraced by the cap strip. Mastic or "hot melt" beads of predetermined volume are disposed in the pocket in each wall section, and distributed when the pockets are deformed during the seaming operation in which the seam forming edges are interlocked.
