An interlocking siding panel comprising an upper lock portion, wherein the upper lock portion further comprises a riser segment contiguous with the back face of the panel. The riser segment transitions to a bend fully reversing direction to form a nail hem segment. The nail hem segment terminating at a first bend leading to a first riser leg transitioning to a planar segment through a second bend. The planar segment terminating at a third bend leading to a second riser leg that terminates at a fourth bend forming the proximal end of a locking leg; a front face; a back face; and a lower lock portion disposed laterally opposite the upper lock portion. The lower lock portion further comprising a lower flange and a return leg, wherein in operation the return leg of the lower portion of a first panel is inserted beneath the proximal end of the locking leg.

Siding panel with interlock

Disclosed herein is an interlocking siding panel system for securing to the side of a structure with planar surfaces. When the panel is secured to the structure through the nail strip a full contact strip opposite the nail strip lays flat against the structure causing the panel portion below an point of inflection in the panel to raise up off of the structure creating a gap to facilitate movement of moisture past a locking leg that integrates with the panel below.
