Thoughts on the roof and skylight

With the trim and siding figured out (but not yet installed), I have been thinking a lot about my roof. The maximum legal height for a trailer without a special permit is thirteen feet and six inches. My house, sitting on a trailer thirty-two inches high, will be about twelve feet without the roof. Obviously my roof will need to be removable if I want to move my house without worrying about overhead wires or the law. My roof framing is made up of three rafter sets connected by purlins (see this post for a diagram) which will all be removable. The roof itself will consist of four bolt-on panels. Each one will have beaded pine board on the bottom side for my ceiling, 2x4 framing with insulation in the middle, followed by skip-plank sheathing and then standing seam copper on the outside. The construction of these panels will be straight forward, much like the roof panels I used to make when I worked for the timber frame company. My challenges will be making a removable ridge cap and a seam down the middle that will keep the rain out.

The only other detail that I need to figure out is the skylight. Originally I had wanted to build a raised unit that straddled the ridge as shown in this post. I am realizing that I need something simpler though. My dad sent me a link to the website for New England Skylights (NES), a company in Watertown, Massachusetts that builds beautiful copper windows. They do many new and restoration projects all over New England. The two photos below are of a window made by NES that is actually very similar to what I had envisioned having on my house.

Since my roof will be removable, I think I will simplify the window by limiting it to the South side only. The window in the picture below is a restoration done by NES which fits all of my parameters and looks incredible.

I love the low profile of this window and how it fits so seamlessly into the standing seam roof. I am going to do everything I can to reproduce this. Ideally, I would make it so that it is hinged at the top to allow it to open. Time will tell if i can do this though.
