This was one of the trickiest roof sections to complete. The square holes are 48 inches by 48
inches and will soon have curbs installed for skylights. The drainage got even trickier because
of those skylights and their close proximity to the parapet walls. We had to go with six scuppers
to get the job done since the crickets needed to be so shallow to get around the skylights.
Here is the same roof section showing how these particular scuppers spill onto other roof
sections. We probably could have simply used framed tunnels though these parapet sections
instead, but copper lasts for centuries and it looks cooler.
