Cupola windows and sheeting the roof

Yesterday, I made a trip to Lowes (I hate giving them my hard-earned money) and bought windows for the cupola and some tar paper for over the roof sheeting. In the afternoon, I sheeted the cupola so that I could install the windows. I figured I could get at least one window in before it got dark. Once I got started, I didn't stop until I had all four in. It's kind of exciting to have the first four windows on our house!

Since it wasn't raining today and the rafters were in place, it was time to tackle the roof sheeting. I bought 44 sheets of 7/16" OSB about a month ago for this purpose. My original plan was to save the $300 or so I spent on OSB by using pallet boards to sheet the roof. They would've worked alright, I'm sure, but the OSB speeds up the process and makes a more even surface.

My dad (who I am very thankful for) and I started the sheeting process on the front slope of the roof. This is the 8:12 pitch side. The area to be sheeted was 20' by 40'. It actually went quite well. We were able to get the whole front side sheeted in about four hours. After lunch, we used nearly four rolls of 30# felt to paper over the OSB. I didn't take pictures of the work in progress because I was working. I did take a few pictures after lunch during the brief period of sunshine. Once we finished the tar papering, it was too dark to take any more. There'll be more photos when we work on the back of the roof.
