• a J-shaped trough;
• and
• at least one mounting bracket for supporting said J-shaped trough on the periphery of said roof;
• said mounting bracket comprising a first upstanding section, a base section extending orthogonally and rearwardly from the bottom of said first upstanding section, said base section terminating in a second upstanding section spaced rearwardly from and parallel to said first upstanding section, said second upstanding section terminating in a first edge for supporting said trough, said mounting bracket further comprising an angled section extending forwardly upwardly from the top of said first upstanding section and a third upstanding section extending upwardly from the top of said angled section and being spaced forwardly and parallel with respect to said first upstanding section, said third upstanding section terminating in a second edge for supporting said trough;
• said trough having a first wall, a base extending orthogonally and rearwardly from the bottom of said first wall and a second wall extending orthogonally from said base and parallel to said first wall, said second wall terminating in a first lip for engaging said first edge of said second upstanding section of said mounting bracket, and said first wall terminating in a second lip for engaging said second edge of said third upstanding section of said mounting bracket wherein said base of said trough is spaced from and parallel to said base of said mounting bracket and said first wall of said trough is spaced from and parallel to said first upstanding section of said mounting bracket when said mounting bracket is mounted adjacent to said periphery of said roof.
