   Unless you're completely committed to PVC trim, you should check out MiraTech trim boards.

   Most anything should work is southern CA.

   2x material works with only very few ext trim styles.

   Windsor makes a 5/4 that is solid.

   I like the idea of the Azec, but it is hard to install as fascia without three guys because it is so floppy, and it moves from thermal expansion a lot. I don't like a moving joint in fascia.

   Are you going to have gutter on this? axec would need a subfascia as well behind it for mounting strength.

   In your area, I would be looking at redwood.

   Thanks Piffin, Ranch style typical tract home nothing special. A large pergola will have the rafters attached to the fascia thus the need for 2x material. or possibly It could be blocked out and 5/4 could be used.Looking for something that doesn't need to be painted every 2 years. Though the existing redwood fascia is 44 years old. Suppose I could get by with Windsor- 1 for another 20-30 years ML

   The pergola plays big on this decision then. What material are you planning to use for it?You want something that can act structurally because of adding this other to it, and you will have water flowing past a critical joint there. If the pergola is CVTG fir, that is what I would use for the fascia. if redwood, then a redwood fascia.It will take paint or stain the same and will age the same way.

   Heres what the Mrs. has in mind.I posted this over on JLC.The little princess approached me last night with this sketch she did in Excel and wants a pergola built on the back of the house. While I'm more of a finish carpenter than framer It's something I can handle after the all the flat work is complete.The post's are to be 4x6 and sandwiched with 2x8? with perpendicular 2x6 rafters on top of these.Can anyone tell me if these can span these lengths or will something larger or additional posts be needed.I was hoping to place the posts close to 11' on center.The bottom edge of the sketch along the 44' length, the sandwich beams would be hung from 2x8 fascia on hangers.

   You don't need to worry about load and spans since the sky it is holding up is not too heavy.( OK - maybe with all that pollution in SoCal...LOL)Try the search function here for pergola. There have been some inspirational threads with photos if you can find them

   I'd build a self supporting pergola that is just tacked to the fascia.  Then you can use a "normal" fascia material like Miratec.    Also, if you change from an existing 1x fascia to a 2x fascia, re-doing the roof (to some degree) would seem in order.

   Even though the pergola won't be that heavy, rafter tails are not meant for supporting weight.

   Or - if you feel you must attach to the fascia, put blocking between the tails, install normal fascia, and then attach a 2x8 (or whatever) ledger to the fascia and through bolted to the blocking.

   If you add a bit more detail to the sketch like the location of the beams and the direction and spacing of the rafters, etc, you can probably get some specific opinions on the spans.  Might better start a separate thread for that since it is really a separate issue from fascia.  To me, with a pergola, the beams and rafters are carrying little weight so the real question is will the members used for the spans be large enough to be able to not end up sagging under their own weight and looking fugly.

   Here you go Matt The sandwich beams will be 2x8 and attached to each side of the 6x6 beams while 2x6 will be laid perpendicular across the top of these on 2' centers.ML
