The cleanest look for a gable end with a closed eave is to angle the soffit therefore eliminating the need to resolve the eave at the gable end.
Gable roof soffit corner.
Here s how to frame a boxed soffit on the eave and gable end of a building.
From the edge of my fascia board its like 9 to sheathing.
Before you nail it slide it a tiny bit out from the back of the f channel approximately 1 16 inch.
Start at one corner of your house and work your way around using the drill or electric screwdriver to drive one wood screw twice as long as the material is thick through the soffit material and into the gable at each corner of the piece and one in the middle.
Begin at one bottom edge of the gable and slide the soffit into the f channel along the wall.
Nail j channel against the existing soffit into the soffit framing.
Hip roofs have a continuous cornice that extends completely around the building.
This configuration gives the look of an open eave but it has the same benefits ease of maintenance and energy performance as a closed eave.
Soffits are actually part of the cornice or eave the point where the roof projection and the side walls of the building meet.
This is a very small amount but it will keep your soffit from bending later.
Framing a gable roof building a gable with barge end purlin struts and collar ties.
So how do you end eave soffit and transition to gable soffit.
A gable roof has a cornice along the side walls formed at the rafter ends.
The other end will be closest to you.
My next area of concern is which is the very corner where the gable end meets the 45 degree eave roof edge.
That rafter outside forms the overhang for the barge boards to fix to and so the soffit boards and ventilation are continuous all the way.
Each piece of 4 foot length should have a minimum of 6 screws in it.
The good news is unlike most roof repairs you can fix an eave or gable overhang rake without climbing onto the roof.
Rake boards follow or parallel your roof pitch.
They form a corner between the siding and soffit.
Thanks for the info.
The picture above shows the plan view of a gable roof ladder trusses are made up using four noggins bridging at each corner to support a rafter outside the building.
This is how i did my pole barn workshop and at the end of the video i also show.
On corners notch the top and backside of the j channel the width of corner boards and cut the bottom to extend past corner boards the width of the next piece.
Cut a 45 degree angle on adjoining pieces to give a mock miter appearance to corners.
