What type of wood for soffit and eave repair?

I have a large rotten section of my soffit and eaves that I've been putting off long enough and it's now time I get off my arse. I've never taken on this type of project, though, so I'm oblivious as to what's the best type of wood to use. Do I use untreated wood and prime/paint with exterior grade prime/paint or do I use treated wood, wait a few weeks, then prime and paint? I'd imagine the treated wood would warp and shrink, making it less than optimal but I don't want to be right back up there doing all this again in a few years if I use untreated wood.
What is used in this type of construction?

I've always thought that it was just untreated.
I actually have this project to do as well, but I have to pull off gutters to get to the wood.
I was planning on using untreated and priming all of it only painting the exposed portion.

I had this done with some gutter repairs several years back after a pine limb fell and damaged the gutters. They used untreated plywood, ripped to the right width and used some paint we had left from having our addition painted. We had color matched some existing paint on the house to paint the siding, and they did a couple coats of that on the untreated wood and it has held up great. There was another section where the soffit was a little soft, and I paid the crew extra over the insurance claim to make those repairs while they were there. Also paid for nicer gutters than we had previously. It seems like a simple DIY type job, but it was up on the 3rd floor of our house, so I was glad to pay a pro to do it all. Thinking about tackling a few spots on the front of the house, but that eave is just over a one-story section.

I'm assuming you mean soffit and fascia. You can buy ploughed fascia (it has a groove cut in the back where the soffit fits in) in either an engineered product or finger-joined fir. I think it comes in 1 x 8 x 12', but don't quote me on it. I don't remeber the size of the groove. I would use an exterior grade BC plywood for the soffit. Nothing pressure treated.
Prime your fascia if bare, or use pre-primed. Prime and caulk the soffit once it's up. 100% acrylic latex paint for finish. Latex primer for both.

Correct answer
1 in. x 6 in. x 8 ft. Finger-Joint Fir Double Plow Fascia Board $20 at Home Depot

Use 3/8” luan plywood for the soffits.
Use either fir fascia or an engineered fascia. It will have the groove already cut in. The double plowed fascia has two different sized grooves. Use the 3/8”.
Do not let any treated wood near your soffits and fascias.
Just prime as soon as you can after install. The fascia will probably be pre-primed.
That’s the downside of gutters. They can hold water and debris against your fascia and hide it from you. By the time it’s noticeable you are already looking at a sizable repair.

Untreated. If this is a house you plan to keep long term I would pay the extra money and put in hardi siding for the soffit.

Any recommendations on companies to hire to do this type of work?

If you’re in Nola, call Alex or Scott @ C3NOLA. If you’re outside Nola, they might still come to you.

I replaced 80% of my fascia with LP smart side which matched the existing. If needed I would’ve used LP smart side soffit.

This is absolutely the way to go.
Out with wood, particularly now that treated lumber isnt produced the way it used to be due to government regs.
Hardie >>> everything else.
