Carport using unusual construction method

I am making progress on the concrete-pillar carport.
Big thanks to FABO member "adriver" for pointing out that the roof pitch I had originally planned was too small. So I built pony walls on top of the front and middle rows of joists to raise the pitch to 2-1/2" in 12", which I believe is adequate to permit the use of asphalt shingles.
The only way I could find to cut the bird's mouths accurately in the rafters was to mark and cut them in place.
It's a lot of work to install the rafters, but I am going to take a break and install some roof sheathing for awhile where the rafters are already installed. Then I will be able to start moving my cars out of the garage. I am really looking forward to that.
Even with only about half the rafters installed and no roof sheathing, the structure sure does seem solid.Carport 6-17-2017.jpg
