Interlocking roofing panel system
First Claim
1. A roofing system comprising:
- a plurality of roofing panel assemblies, each roofing panel assembly having;
a base having a substantially planar surface;
a plurality of I-joists having an upper flange, a lower flange, and a web, wherein the base is attached to the lower flanges of the plurality of I-joists; and
a cap having a substantially planar surface, wherein the cap is attached to the upper flanges of the plurality of I-joists;
wherein the plurality of I-joists includes a first edge most I-joist and a second edge most I-joist, wherein a first edge of the cap is attached to the upper flange of the first edge most I-joist such that a portion of the upper flange of the first edge most I-joist is not covered by the cap, the portion defining a first distance, and wherein a second edge of the cap extends beyond an edge of the second edge most I-joist for a second distance less than a width of the upper flange of the second edge most I-joist;
wherein the second distance is also less than or equal to the first distance;
wherein a first edge of the base is attached to the lower flange of the first edge most I-joist such that the first edge of the base extends outwardly no further than an edge of the lower flange of the first edge most I-joist;
wherein a second edge of the base is attached to the lower flange of the second edge most I-joist such that the second edge of the base extends outwardly no further than an edge of the lower flange of the second edge most I-joist; and
wherein adjacent roofing panel assemblies are attached such that the second edge of the cap engages the portion of the upper flange of the first edge most I-joist not covered by the cap.

Abstract
A roofing system includes a plurality of roofing panel assemblies. Each roofing panel assembly includes a base having a substantially planar surface, a plurality of I-joists having an upper flange and a lower flange, wherein the base is attached to the lower flanges of the plurality of I-joists, and a cap having a substantially planar surface, wherein the cap is attached to the upper flanges of the plurality of I-joists. The plurality of I-joists includes a first edge most I-joist and a second edge most I-joist. A first edge of the cap is attached to the upper flange of the first edge most I-joist such that a portion of the upper flange of the first edge most I-joist is not covered by the cap. A second edge of the cap extends beyond an edge of the second edge most I-joist for a distance less than a width of the upper flange of the second edge most I-joist. Adjacent roofing panel assemblies are attached such that the second edge of the cap engages the portion of the upper flange of the first edge most I-joist not covered by the cap.
