Sorry it took so long, yesterday was a cold, wet day here, too dangerous to work on the roof.
rv1pop these are the answers to your questions.
1) the down hill slope of the roof is what direction? Perpendicular to the road or at an angle...I am guessing about 8 degrees looking south of west...
A. The roof faces Due South and is perpendicular to the road going North to South.
1a) And what is the slope of that roof? looks about a 3/12
A. Using this site
http://www.pole-barn.info/roof-pitch.html, I measured and it would appear to be 7/12.
2) Has the foot been tarred down yet? (let me think on this tomorrow, but if it has not, it looks like it needs to but rotated -- maybe would be easier 180 degrees out -- got to look at one here.)
A. The holes were caulked when we bolted it down.
3) is that roof an overhang or over a "room"?
A. Over a room.
4) does the post have slot to allow it to rotate in the base?
A. No, once the post is attached to the base it can be slid forward and back in the base but that's all.
And BTW it would appear we bolted the front half of the base to the roof joist, the back isn't since they are about 2' apart.

I attached a pic showing I flipped the J-Pole around.

I posted a pic of the Elevation meter on the back of the dish at lowest possible elevation, also a pic showing the bolt I was talking about hitting the J-Pole.
