Off the dome he has a series of bump outs at ground level, kitchen nook, front entrance, side entrance, and who knows what else. The tie in from the garage is going to go where the side entrance is. Right now he has a 24/12 gambrel roof over the side entrance, the top part of the gambrel is a 1/12 flat that slopes
away from the dome. (Wow, a picture would be worth a lot here). Oh! the current tie-in from the entrance to the dome leaks

. I wasn't suprised to hear, I saw Roof Tar all around the tie in parts.
You can imagine why I was distracted on this one. Sigh, maybe I should do the garage and run like hell when he calls me back for the tie-in.
I'm thinking its best to locate the gable end towards the dome, seems like the tie-in would be easiest. since his 24/12 ends on 4' knee walls. Gonna try to make sure the peak is higher that what I have to tie into. Jeez i forgot to mention he has an Octagon Skylight right above his flat roof/gambrel leak :blink:. I'm getting a headache. Where was I? hmmm 2x4 or 2x6? seems like this it's a no brainer compared to what I'm gonna be thinking about in the spring.
