Framing eaves/ends on rigid insultd-roof
Wonder if anyone has any suggestions on framing eaves and gable ends on a rigid-insulated roof thats rafters stop at the top plate. To better describe, the section assembly of this particular roof type from interior to exterior is: exposed 3×6 rafter, TnG decking, 6″ Rigid insulation, 2×4 sleepers 24″OC (to sandwich the rigid to the rafters/decking – this is also the vent cavity), plywood sheathing, and finally an asphalt shingle layer. The 3×6 rafters stop at the wall plate (no rafter tail). Code requires ladder-type framing at the gable end.
Considering this type of roof for an addition on my own house, but cant get my head around how to build out the eaves and gable ends – anyone built anything similar? to be a 5:12 gabled roof, WI climate, btw.
Thanks in advance –

Greetings Iltud,
This post, in response to your question, will bump the thread through the 'recent discussion' listing again which will increase it's viewing.
Perhaps it will catch someone's attention that can help you with advice.

Before winter I built a chimney, and shingled the sides of my house, which were already impervious to rain, with imperfect and sappy shingles made of the first slice of the log, whose edges I was obliged to straighten with a plane.

A couple of suggestions:
Add purlins above your 3x6 rafters. This allows your TnG to run down the slope and form the overhangs. Run your 2x4 sleepers horizontally from 2'-0" in to form the end gable.
Rather than laying your 2x4s on edge as sleepers, lay them upright. You can either add more insulation between them, or have more airspace. Plenty of strength this way for the overhang and gable end.
