My buddy is building a house using an old barn, Decorative posts and braces. Under the beams. Some are structurall too. No mortises or tennons. Only 20d nails pinning it together.
The framers are doing some things that make me scratch my head. First thing I noticed was the way they framed the openings for windows and doors. Not the best way. I guess the box headers are ok too, because the load is carried by the beams. ( in most cases )
My late est observation is on the roof. I’m not a roof framer, Maybe i don’t know what I am talking about. The rafters are 2 x 12 , Nailed to a built up ridge pole , Up top. At the bottom the have no birds mouths. Only a seat cut, toed in to the top plate. This level cut runs out to a point. The run for each rafter is at least 18 feet. In all fairness, I haven’t seen the finished product. I guess they will use colar ties of som sort. The roof sheathing will keep it all together too. The seat cut is long and overhangs the plate by a foot. No notching. Not too sure how they plan to build the soffit. But what about that birds mouth? Maybe it will be ok, when its done
Are Birds mouths that unimportant?
Where there’s A wheel there’s a way, got any wheels?

There's three pictures that I'll post.
1) The rafter with the 12" overhang as you said. The bottom of the rafter is even with the inside plate. Which is fine.
2) Same version as 1 but with no overhang.
3) Is the 12" overhang, but the bottom is cutin on the plate which is NO GOOD.
I hope there not cut like 3.

Birds' mouths are a pain in the keister. If I can avoid them, I do.
I build a lot of my roofs with a special type of curved eave detail that is typical of Quebec rural architecture. To do this, I need a rafter that lands right on the top plate and the toe is cut off 90 degrees to the seat cut as in Framer's drawing# 2. Then the overhang is framed with its own rafters, like a porch or veranda roof, usually hanging on a ledger. Between these two rafters we put what's called a coyau (I haven't got a clue what it's called in English, sorry), which is piece of 2x cut to the needed curve on the top edge and mitred on the ends to fit from one rafter to the other. Then the roof decking is laid on; if it's plywood, we kerf it to bend it; otherwise we use 1x6 and just lay them in; by the time the shingles are on, all you can see is a nice, fair curve.
Haven't had one fall down yet.
Sorry I don't have a pic of the framing; but take a look at the main roof on this shed.
