Draw a full scale mockup and snap a line with fascia in kind.
Roof sheathing flush with fascia.
Run fascia the thickness of the plywood higher than the fly rafter on the gable and flush on the sub fascia.
Nail thefurring strip to the fascia board near the fascia top tight under any extending of roof decking usually absent.
But if you snap it at 40 inches then the sheathing will not project over the subfascia or true fascia.
If the drip edge is laid right up against the fascia or rafters then because of surface tension the water runs right up against the fascia and underneath the soffit.
View flush soffit panel.
The drip edge should be installed over a piece of 1 2 furring strip so that it stands off from the fascia or rafter tails.
Since joists will be spaced on 16 or 24 inch centers 8 foot pieces of fascia work well.
Chalk your line up the rake 48 from the point where fascia meets sub fascia.
On the front of the roof edges the original roof deck sheathing was cut back flush with the wall and the fully adhered membrane folded down around the rafter tails to catch the wall water control layer and air control layer.
Step 2 hold your first piece in place starting flush at one corner with the top edge of the board pushed tight against the bottom edge of the roof deck or flush with the tops of the joists.
This was then foamed to complete the air seal.
Flush soffit panels line up together for a modern minimalist look.
In the u s roof sheathing is almost always composed of wood usually osb oriented strand board or plywood.
Roof sheathing or decking is one of those elements.
When sheathing a roof the first step is to snap a line so that the first row goes on straight.
Flush soffit concealed fasteners.
This soffit option will exceed your expectations when it comes to strength and aesthetics.
Flush soffit works well as a subtle interior panel wall panel and as part of a roof venting system.
