Just to support itself or will there be some kind of loading?

9 ft easy. 2x6 treated ypine is 9' at 60lb live load. this is for floor for a deck 24" O/C . 16" and even 12" on center could span much more as w oak has much more shear. if its for a roof rafters. there is a lot more to figure in.

Well it would also matter a little if the board is on edge or laid flat. the exact usage is important if asking any question of this sort. as a collar tie or open joist the span could be greater. It's been few decades since I did the math, but for most purposes I think oak and syp are about equal in span and load capacity.
This calculator actually lets you pick the wood and play with loading and deflection and tells you the spans and required end bearing.

Lot of variables; Live load:Dead load weight?
Roof pitch?
Spacing OC?
How much bearing surface?
Deflection allowed by state uniform building code?

I'd double up the 2x12's on the sides,with some plywood sandwiched.And 3 6x6 uprights on footings for end support.
You making a car port?16 feet seems too much for a carport without a center upright.

The pitch appears to be somewhere between 4/12-5/12? If you’re looking at a clear span of 16’ on 24” OC with possible snow loads? I’d say you’re gonna be borderline. I would guess 2x8’s would be a better choice. Check your local codes and with your local inspector. Better safe than sorry.

Remember we are working with white oak boards with no knots

I wouldn’t know what it’s like not having zoning or building codes. lol
The ridge carries only minimal weight. Nothing more than a nailer. Unless it’s a load bearing beam, like an LVL or Micro-Lams? Think of it like pre-fabbed trusses. No ridge beam. You’re collar ties (ceiling joists) keeps the exterior walls or headers from spreading. Thus keeping the ridge from sagging.

Now as far as oak? They will be stronger than SPF. But maybe not so much as SYP or DF.

Are the oak 2x6 kiln dried? Or green? If air dried? For How long?
If you choose to use the oak? You’re not gonna be fond of nailing. Even if using an air nailer.

If you nail a plumb upright from each joist to the peak,
it'll fly as ceiling joists.
BUT,
Putting decking on now makes them floor joists and no 2x6s not enough.
Someone some day WILL load that floor.

Go and talk to a building center in your area. Not a box store, a real building center.
Even pay the man for his knowledge.

Now looking for tin hat.

20' clear oak is big bucks. I assume you already own them.

So, I'ma confused, are you using them as rafters? That's my take, but then; are you extending the gable roof as you have drawn with collar ties or are you talking of adding a shed roof off the eve (gutter line) ?
Did you use the calculator I linked?
If you are using them as rafters under a metal roof, why are you using plywood?
Or is the 20' collar tie in the picture what you intend to use the 2x6 for? fwiw, I see no reason to add the 2x12 at the ridge, imo, that just adds load to the system unless it is supported from the ground.
And then, the photo of the gable appears to be of a 3/12 pitch and your drawing of a 8/12? The pitch angle makes quite a difference in how the member loads and transfers the load. You really should have a tie much nearer the peak and one at the beam level. And if your intention is to use these as joists or loft, then all bets are off, go to 2x10.

X2 that does appear to be a 3/12 pitch on the existing building. I would just have some engineered trusses built to match the existing roofline. Sell those white oak 2 bys and you'll possibly come out with a better product in the end and make money too.

I agree there is no need for plywood on the roof. It just adds weight. Nailers every 16 or 24 inches and attach your metal to those

Personally, I would never use clear white oak as you plan to. They should be easy to sell if you have no other use for them.

Driving a nail through dried white oak won't be fun without drilling first. And, if you have a use for wood that has to be near weather and rot proof, it hard to find better than WHITE oak.
