Rake fascia; looks and function
I will be replacing the fascia when I replace my sheathing.
I've mentioned in other discussions that, ultimately, I want to install Hardie, but I'm not ready to do that yet. Hardie requires the trim to be at least 1" (actual) with shingle style so that the siding is not proud of the trim.
My current fascia is 1 x 6 (3/4 x 5.5 actual) with a shorter ( 3/4" x 1.5" ) piece tacked on the front of it and tucked up against the roofing drip edge, forming a little offset.
Does that offset provide any function?
Would it matter if I doubled up two 1 x 6 boards? I'm thinking of regular pine 1 x 6 covered with an Azek 1 x 6. That would give me a 1.5" (actual) trim which would be fine with Hardie.
I don't think it will look as good as the offset I currently have, but I can't think of anything else to do. Do you have any suggestions?
Also, I think I'll use house wrap too. Would the house wrap be installed before and under the fascia trim?
Thanks in advance.

That 3/4" x 1-1/2" piece at the top of your facia works with the metal drip edge to provide a drip edge that keeps water away fro the face of the facia. Making a double thick full facia will still work, especially if the outer surface is a composite material such as Koma or Azek, but you could have some paint weathering problems on your facial due to the water drippage.
What you have now is really a double use - the 1x2 is a drip edge, and is a holdover from older construction from before there was common use of metal drip edge. In your case, you also have the metal drip edge to direct water away from the facia surface. Basically, right now you have two styles of drip edge working together.
The house wrap should be e=applied to the entire face of the wall beneath the exterior siding. Since your facia is on the same plane with no soffit, install the housewrap behind the facia as well.
