It all started out with this
I thought I'd just replace the asphalt shingles. Then I thought how nice cedar shakes would look. Then, when the roofer was replacing the shingles on the house, he looked at it and said, "You need to replace the sheathing too." He was right. So I thought, "Since I'm going that far, why not add a cupola?" And that's the story of the birth of this project.
I tore off the entire roof, rafters and all. Then I built the center octagon with cedartone PT 2x6s and connected the 8 rafters to that with Simpson brackets.
With that in place, I sheathed it with 5/8" siding grooved 4" O.C. and faced the grooved side down. Because I didn't know how long it would take me to lay the shakes down, I laid down some 30# felt and nailed in the lower battens.
I sealed the sheathing with Defy Cedar stain before cutting and installing it and added the fascia.
Then I began working on the cupola in my basement shop. I started by making a downward facing finial out of a piece of 4x4 cedar. I then made the 8 rafters and screwed and glued them to the finial,
I then began on the side walls. I started with 2x4 walls but didn't like the way it looked, too clunky.
So I cut a profile on the inside with the bandsaw.
I used a 45 degree router bit to shape the edges.
Then I began working on the face. I was thinking of louvers, considered plexiglass but that offered no air flow, then finally decided on this:
The cedartone sort of clashed with the cedar so I glued strips of cedar to the outside to match it up. All of the cedar I used started out with some 4x4s and was resawed to the shape I needed. The outer frame of the lattice is 1-1/4x1-1/4 while the inner parts are 1x1.
I put on the sheathing, which I duplicated what I did on the main roof and started on the roofing. I had never installed cedar shakes before. I found the Cedar Shake & Shingle Bureau and used their roof installation manual as my guideline.
When I finally reached the peak, I couldn't decide how to finish it. So I made a piece of metal flashing and pondered how I'd proceed from there.
One very hot day I went back into the shop and turned another finial on the lathe. I knew I couldn't make it too pointed as the cedar would most likely split. I then made some "legs" and dry fit them to the finial.
I removed the legs and rounded them over on the router table. But I still didn't like the look.
So, on another scorcher of a day, I brought some more shakes down to the shop and cut them to fit the metal flashing, keeping the bottom edge 7-1/2" from the lower ridge shake.
Even though I didn't want to pierce the metal flashing, I knew I had to if I wanted the top finial to stay in place. So I drilled a 1" hole in the bottom of the finial and into the top of the lower finial. Then I cut a 1" oak dowel as my anchor.
