Astro-shack now has a roof.

After the marathon build of the roof panels, tar paper and shingles yesterday, we had 3 out of 4 of the roof sides done.  Today we had the procedure figured out pretty well and the final side was done this morning.  We got the edge shingles installed also and they look quite nice!
Traci had to finish the top shingles along the top square since I had to go into work for a few hours and assist with a software upgrade  *ugh*.
I made it home before dark and we worked on a raised edge that the dome flange will sit on, and some flashing for the joint between the dome and roof.   More photos of that later.
Rain forecast the next few days, so it's tarped over again.  Probably not enough daylight after work now to get much done, but next weekend's forecast is looking ok so far.  I'm hoping to have the dome in place and get started on the siding and maybe have that done.

Our engineering of the roof worked.  No inside support is needed.

Roof done, now the dome is next.
