Patent ID: 7178295

Claim:
A plurality of shingle assemblies for use on an inclined support surface comprising: a plurality of barriers; a plurality of bases, each base having first, upper and second, lower edges; a support securing individual ones of at least some of the barriers to individual ones of at least some of the bases to create a plurality of shingle assemblies, the base of each shingle assembly underlying at least substantially all of the barrier of each shingle assembly; each said shingle assembly defining a venting region between the barrier and the base for temperature regulation; the barriers each comprising an upper surface and first and second barrier edges on opposite sides of the barrier with the venting region fluidly coupled to the upper surface; and said first, upper and second, lower edges comprising first and second interengageable elements so that said second, lower edge of one base is overlappable with and is interengageable with said first, upper edge of an adjacent base to be capable of resisting first and second disengaging forces, said first disengaging force oriented perpendicular to said edges along a plane oriented parallel to the base, said second disengaging force oriented perpendicular to said edges along a plane oriented perpendicular to the base.
