I am building a shop with 2x6 rafters and 1' overhang. End rafters will be supported by gable stud wall so it is ok to notch end rafters and install 2x4 lookouts by face nailing them into the notch and end nailing them into the adjacent rafter, correct?. I also will have a 10' lean to (3:12 pitch) with 2x6 rafters that sit on top plate with main rafters and a beam at the bottom. The lean to will not have a wall underneath them for support (open on the sides) should I do the same for lookouts or install 2x6 lookouts without notching lean to end rafters and just face nail to end rafter (lean to barge rafter will tie into main roof barge rafter) Also, I will have 2x4 purlins 2' OC for metal roof, (no sheathing) will these be enough to hold the lean to barge rafters without lookouts? I am also using a 2x8 for gutter board that bottom of rafters will tie into. (2x6 rafter + 2x4 purlin) I am not extending beam past end rafter to catch lean to barge rafter.
