Shed-style roof fascia vertical or perpendicular to top surface?

We don't get a whole lot of shed style roofs out here in Tucson. Generally everything is single-story santa-fe style parapet walls, balloon framing.

So for a shed style roof (I-Joists for members, LVL (or LSL) for fascia) is it more common to make the top and bottom fascia vertical or a right angle to the top surface. Slope is 1-1/2":12". It'll be standing seam metal with matching wrapped steel fascia. Is this a purely aesthetic call or is there something functional.

I would imagine vertical would be better for drainage at least at the top as the fascia wouldn't be in direct contact with downward rain, but a fully metal wrapped fascia probably makes that point moot.

I'm inclined to frame it perpendicular to the roof as I think that'll look better and a 14" LVL will fully cover the end of a 14" I-Joist.

That's pretty great looking. It really doesn't look like 16" installed. I would have sworn it was around 12" from the 2nd photo.

shouldn't that fascia wrap have another tab at the bottom to wrap around the bottom of the fascia?

The upper part is only 12 . The 16 in on the bench goes on the beam over the patios.

We like to cut the TJI down on the over hang and use smaller fascia if the plans will allow it.

That looks great. I guess I’d have to run some numbers to see if I can go to a 4’ overhang using that technique. The TJI design guide limits you to 2’ that way.

That shop has a 3 foot over hang. After the sofit and standing seam roof it looked good.
