I put the sheathing up before building the rafters. When cutting my rafters, I like this website for figuring out my cuts. Click on the tab "Roof Calculator" and put in your numbers. Measure from the outside of the sheathing, not the studs.

ZIP System is a higher quality OSB then regular construction OSB. When cutting it, you will notice that it's more solid and tighter. The green coating allows you to leave it exposed for long periods of time and not worry about the OSB getting wet, delaminating, or being damaged from the weather. When the price was lower, it was a no brainer to go with ZIP System over the less expensive OSB and then cover it in House Wrap. All of my house is done in ZIP System, but last year when I started adding on a 3 car garage, I couldn't justify the cost for it, so I went with regular OSB and House Wrap.
ZIP Tape is used to seal the edges, and it works really good. I keep a roll of it in my truck all the time because it's the very best tape that I've ever come across. It's also gone up in price and it adds a lot to the cost of doing the walls in Zip System. I used the ZIP Tape on my House Wrap where it connects to my house instead of the House Wrap tape. I also use ZIP Tape to seal my widows and doors instead of flashing tape, or House Wrap tape.
