After much deliberation, we chose 4 triangles on the dome surface to be our windows.
Then, Darcy at Focus Roofing got busy adding the ice and water shield layer to waterproof the dome.
We decided to go with a flat-stock, 26 gauge steel cladding using a combination of folded and standing seams.
Here is a detail of how the roof sections meet, and we think it looks great! It's like stealth-bomber steel origami, and Focus s doing a terrific, if painstaking job.
More updates soon as we complete the dome roof, install the windows and finish the siding on the addition areas.
Wish us luck!
