My garage will have open rafters (2 x 8). With a 1 x 6 trim board attatched (mainly as a place to install a gutter and for some shadow lines.
My question is what is nice simple way to tim out the gable end.
I was thinking that I would run an additonal 2 x 8 at the gable end (over hang is 12″) and incorporate corbels for support–that would provide support for the roof sheathing and shingles–however then I would have the rough 2x 8’s exposed on the gable end–should I just attatch 1 x 8 board to the end and call it done or is there a better more elegant way?
Pictures or diagrams would be very cool at this point.
Thanks

Normally when framing & siding, around here on a mid priced house we use 2x6 subfascia and 1x8 for fascia. I understand you don't want subfascia on the horizontal eaves so just nail up your 1x8 to the rafter tails, but on the gable end, if possible rather than using a 2x8 fly rafter (out west called a barge board), I'd use a 2x6 and then a 1x8 fascia. Also, personally, I'd also add a 1x4 to the rake, to, as you say, give a shadow line. I like using 1x4 Azek since this location sees the most weather of just about anywhere on the house. This 1x4 is nailed to the outside of the 1x8 rake trim.
The corbels to support the fly rafter is a good way to go, especially if you are trying to achieve the craftsman style of architecture, but here is anther, more common method: If you are still in the framing stage, 2x4 lookouts let into the rafter on top of the gable end are the normal way to support the fly rafter. In other words, let's say that the over hang is 12" (- 1.5 thickness of fly rafter) and the regular rafters are 16" O.C. then the 2x4 lookouts would be ~25.75" and are nailed to the 2nd rafter.
I thought I had a pic but can't find it right now.
