Below is an image created to solve a problem with the butterfly roof and the need to have a second overflow location in case the stainless steel fully soldered gutter failed. The cavity below the metal gutter was lined with peel n' stick ensuring the waterproof installation by diverting any water that makes it past the initial gutter will start to flow out of this gutter. Note the creative use of the Quickflash rubber boot around the scupper.
