   use

   You can do it with a flat return, provided you frame it properly.  You could add statregic knee braces, but no need for every rafter.

   What is a flat return?

   You can tell I'm not a builder;-)

   use

   Your "knew brace" to me suggests an angled brace.

   Flat, that would be level back from the fascia.   Level and flat soffit.

   Ahhh

   Got it. Thanks calvin. I'm gonna brace it. The ledger will be 11' off the ground so there will be plenty of head room.

   use

   Just remember, the connection at the soffit will be less than the pull out forces applied up at the top of the rafter.   An angled brace transfers the load below that soffit line-and lessens the pull out of the top as well.

   How long is this run of "roof"?

   Run

   run of roof is four feet. I can join the brace to the rafter at three feet from the wall and keep the headroom I want.

   Don't forget about uplift

   Wind can have significant affect on projecting roofs such as this. Make your connections suitable if this applies to your area.

   Why is it not a good idea?

   It seems to be "done all the time". What techiniques have you seen for this kind of thing?

   I don't know that there's any "technique" to it.  Generally this is done for a small shed over a doorway or whatnot, with knee braces at both ends.  Typically not much wider that 6 feet or so, with maybe a 2-3 foot extension.  (Though I've seen significantly larger.)  Looks kinda hackish, but I suppose it works.

   Do note that the knee brace needs to brace against something -- if it just bears against standard studs they will tend to bow.

   Thanks all

   I appreciate the comments. I'm going ahead with the roof addition. DanH, I especially like your signature, having just finished a 6.7 kW solar array install on the same shop building that's getting the shed roof.
