Right now I am working on a porch that is getting a standing seam copper roof. This has gotten me thinking about my roof again. One of the holdups on this is the design of the skylight. I would like the skylight glass to be practically flush with the roof surface. Each side will be made up of three panes of glass that correspond to the ribs on the copper roof. Building this flush makes the job of keeping water out of the house difficult. I think I have finally worked out the details though. Almost all of the components will be folded out of the same 16 ounce sheet copper that the roof will be made out of.
The edge pieces will roll into the seams of the roof pans.
The picture below is a detail of the insulated glass unit. I am hoping that one can be made with the top sheet of glass longer than the lower piece. This way the roof can overlap the glass at the top of the window, but at the bottom the glass can overlap the roof.
There are still some details to be worked out, but I think this will work!
