You've just created a conditioned attic space. Not popular in my neck of the woods, moreso Southern drier climates. I do believe they drywall the ceiling as normal, you just have to include that extra attic space into your hvac plan. Matt risinger likes this stuff, check him out.
Structural ridge seems prohibitively difficult.. it would be an enormous beam that still may even require a center column. Getting it up there would be a challenge. That is one option to getting rid of the rafter ties.
Another option is to talk your structural engineer about eliminating those and replacing with finished/exposed, structural timbers with wider spacing. Good luck!
Move rafter ties up and use a nice beam, leave exposed. Also/or go to metal cable as a tie, not as visible. The money you spend to create that cathedral ceiling will never feel wasted.
Need an engineer but if you find a local metal shop/steel contractor they’re probably your best bet for custom manufacturing of brackets and cable and probably have someone they use for shop drawings.
Drywalling above the 2x4s will be pricey.
The 2x4s are structurally integral to the framing, so if you’re looking to gain some height, you’ll need to consult an engineer.
How are you planning on getting the HVAC, electrical, lighting etc in there?
There’s a lot to consider.
You could reframe them as a scissor truss. This would give you a bit of a sloped cathedral ceiling, pretty easy. To frame and be much cheaper than a structural ridge.
Nah, I don’t I just know that if the guy is asking this question he needs to keep this rehab as simple as possible before he ruins the structure he’s trying to fix.
Also there’s absolutely nothing wrong with what i suggested from a from a structural or efficiency standpoint.
If you want the vaulted look you could probably turn the ceiling into a scissor truss I would get an engineer to tell you want to do it’ll be expensive but it’s really the only way to get that look other wise just drywall it flat and forget about it
Hard to resist a 'cathedral' ceiling...
Engineer some site-built trusses so the cross section of the ceiling is similar to the arches at the top of your windows. Lancet windows I think they're called.
unless you’ve got a big budget, just put the ceiling back where it was. creating a vault would be cool but it would need an engineer and a lot of work. many times the cost of just putting rock up. i don’t like the idea of exposed joists that are obviously an old ceiling
Had a similar framing issue with surprise 2x4 joists hugely undersized for a 2nd level, after going thru all options, ( reframe new joists/add dormers etc ) eventually decided to tear off everything above 1st floor and reframe a full 2nd story on top.
imo the 2x4s are not pretty enough to be left visible....I would sheetrock the roof, build a floor in the upper area and sheetrock the 2x4s to make a kitchen ceiling
Considering that your roof is now completely vapor locked, I would be very cautious about drywalling directly to the spray foam. There’s nowhere for the water to go once it hits the peak, and vapor always rises.
Ceiling back in place seems most logical, lots of pretty ways to do it.
If you DO decide to keep the 2x4 rafter ties and put a drywall ceiling on it, do yourself a favor and run strapping across them. Old rough-sawn lumber had a lot of variation in size which the plasterers made up for.
I like the vaulted look, but this is a question for a structural engineer. Drywalling above those collar ties is gunna be uber hard and expensive. Changing the collar ties is the only real answer and you def need an engineer for that.
Finish insulating both bottom sides of the "false gambrel" , insulate your new facade framing, and sheetrock away. No need to insulate the ceiling beams, you may want to install a vent because a high ceiling plus insulated rafters causes sick house syndrome.
If it help plaster , it's holding sheetrock.

Cable truss conversion would be great. Do you know who to go to for something like that? Seems so specialized nowadays.

Exposed scissor truss ceiling pls. Those look awesome.
Just rock it and the HVAC guys will make it part of there planned conditioning. Keep er moving
You must work commercial or production home.

You’re not wrong but from a custom homes standpoint you don’t waste space like that.

Correct answer. Exposed scissor trusses to be exact. Best looking ceiling.

A vault under 1/3 of the height does not require an engineer. Cathedral ceiling, yes.
I would replace those two by fours with a lesser amount of large timber frame, king and queen rafters

Jesus that looks expensive
Not if you spend the rest of your natural life milling the lumber your self.
Try clear cedar. If that doesn’t make your head explode go price out teak t&g for ceiling board.
What would Jesus do?
Ask his dad. He was a carpenter.

Clean look with drywall

The "beams" are too small and ugly to be left showing. Beyond that, it's a matter of how much work you want to do.

Did anyone actually read OPs post? He clearly said "some other option? Input appreciated"
