OK, I did some tweaking without a meter and I think I made some good improvements. First I remeasured my signals inside the house:
110 = 53, 61, 53, 61
119 = 49, 64, 62, 68
129 = 40, 37, 40, 40
I then took a tv and my dish receiver to the roof and re-measured to see if I had any huge signal loss with the cable run:
110 = 54, 61, 55, 62
119 = 50, 66, 62, 69
129 = 41, 39, 41, 41
Based on that test I feel pretty comfortable that my cable run to the TV is OK.
So I decided then to try and tweak things, and I almost got to a point where I lost everything, felt like I really didn't know what I was doing. I'd increase some signals, but make others worse. So, I decided to put things back to where it was in the beginning, or close to it and I got lucky I think. Here are the final readings at my TV
110 = 68, 68, 64, 70
119 = 64, 74, 76, 77
129 = 43, 45, 45, 50
I'm above averages on all of the signals though, so I'm thinking I just leave it alone. Now I just need to wait for the next rain and see if we lose signal as easy as we did previously.
Let me know if you have any suggestions (signal loss during rain is my main beef).

I picked up pretty good numbers on 110 & 119, not as much of an improvement on 129.
