shed roof shape
on the front side of my shed, where the door is, i left the ridge beam protruding/overanging a foot relative to the wall because i want to have some overhang for the floodlight as well as be able to install a hook at the beam for skinning deer and such.
however, i do not want the fascia to overhang, i.e. i want it flush with the shed wall, which means that the roof edge on that end needs to be at an angle, i.e. not perpendicular to the fascia.
Q1: is that a reasonable design ?
Q2: what should i put on the underside of the overhang or is bare OSB board fine?
Q3: should there be a different kind of drip edge on that edge
also, on the opposite side of the shed, i plan to have no overhang whatsoever, i.e. the drip edge to be flush with the siding.
Q4: is that OK and should the drip edge be different for the upside down V side of the roof than it is for the fascia ?

shed roof shape
So basically like the extensions on a gambrel roof over the haymow door(s)? I have done some like that where I ran a 2x6 on either side, at a 45 back to the end rafters or truss, then ran the sheating, drip edge, underlayment, and shingles right over it. OSB on the bottom side of it is going to rot pretty fast, in my opinion; I would use aluminum soffit, or possibly 3/8 cedar plywood, but not OSB. By the way, the 45's that I referred to, as you will find, are compound angles, so you'll either have to do some figuring with your framing square, or use up some of your scrap figuring it out.

Not sure I understand your description...
So you are doing the roof like a prow?
but with your ridge beam extending even further?

and just extend the sheathing? I suppose so, but i'd at least fasten some 2x backing underneath along the edge.

A 12" extension is nothing. I'd go out at least 2'.
You need a solid rake for the gable overhang.
Flash the top of the ridge beam.

he is saying you should have a 2' overhang around your shed.
Larger overhang is always better for your building (especially over doors and windows), but you're free to build it however you want. Just know that you'll be relying a lot more on your cladding and flashing to protect your building.

What I'm saying is that the overhanging part right where the ridge is going to extend, should extend at least 2'. I don't care what the rest of your building's overhang is. Since there will be a space between the top of the ridge board and the underside of the ridge extension, you should put some metal flashing on top of the protruding ridge board to prevent it rotting as a result of wind driven rain
