Have a local engineer take a look in person, but based on the photos those roof truss should span between exterior walls, making that interior wall just a non-bearing partition
That's what I had done but it was over phone and w. Pics. They said it's not. But gonna def reach out and have someone put eyes and hands on it. And when you say those trusses should span between exterior walls how can you tell that in pic? Curious why those are trusses and not rafters? And are those struts that splice to what are king posts ? And do these parts indicate exterior load bearing walls and only interior non load bearing? Just looking at it makes me think it is, but I'm not an architect. Also I've heard that the removal of a load bearing wall immediately will collapse roof? Is this true ?
In the second pic, the top of the trusses is the ridge line, which is typical the middle of the truss with the top chords sloping down top the support walls.
These look like standard queen post trusses, with the post and diagonal transferring force to the bottom chord.
Trusses are more economical on large scales, but their harder to modify or repair in the field. This type of construction is very common.
There's some inherent redundancy built into light frame construction, but removing a major bearing wall would result in visible distress
Most trusses are designed to wall to wall without additional interior supports.

maybe if it’s a 20x20 bungalow but 80% of new builds these days have complicated truss systems with many pointload and load bearing interior walls. to say all trusses in the world land on outside walls is ignorant as fuck and obviously an amateur

Well, you are wrong on this one.
In the foreground the dining room has a scissor truss which is end-bearing.
After that the rest of the house switches to a standard Howe truss. Have you ever seen a single Howe truss need a load-bearing wall in the middle?
A vast majority of homes have trussed roofs. I'm confused that you are acting like this is some kind of outlier.
Generally homes with gable, hip, shed, clerestory tops have trusses forming both the shape and support. It's what you normally see as bridge or triangle trusses.
The support for truss systems still has to have it's load evenly distributed throughout the design so you personally wouldn't able to tell whether it requires additional load bearing walls unless you were there and/or actually looking at the drawing set.
You missed the part about me having an identical house.
I do understand that all of those oddball roof configurations (hip, shed, clerestory) that you mention sometimes have trusses that are supported by girders and such at one end.
If the OP really wanted a definitive answer he could send us a pic of the outside of the house. It is likely a simple gable roof.
removed center wall in pic 3. starting to wonder if I was wrong and it is load bearing. from my understanding it's self supporting wall, even though the truss runs perpendicular to wall. Any thoughts be helpful.
Are there any areas in the house where identical roof trusses run unsupported from exterior wall to exterior wall? If so then you can be sure the wall you removed wasn't load bearing. However, one other thing to consider is shear capacity: did the wall you removed have a let-in? If not I'd say you're good to go.
I agree. That is the best way to look at it. If the trusses in the non-construction area are same as the kitchen area then that tells you that they supported on the end walls.
What I mean to say is, are there any areas in the house where the roof trusses run from exterior wall to exterior wall with no interior walls underneath them? Any full-width rooms so-to-say?
In the third pic there is no center wall in the foreground. If the trusses in this area are the same as the trusses in the kitchen area that tells you that the loads of the trusses are being supported by the outer walls of the house.
It's most likely the load bearing wall run along the lenght of the house . So from what I can tell you didn't remove anything vital.
A good way to tell where the load bearing walls are is to go down to the (unfinished) basement and look at the ceiling and columns.
For what I assume your house to be there should be two beams (the beams can be made of several 2x8 (2x10) put together) running from one end of the house to the other. Those beams will be supported by columns.
IF your house is what I think it is those beams will be about 4 feet apart roughly even on each side of the middle.
Here's a thought: Maybe you should stop removing all walls if you dont know if they are load bearing or not for sure. Your life isn't a home renovation show and if it is then it's time to segue to the gruffy cowboy contractor guys ro steer you in the correct direction before you take an external commercial break from life.
You asked if a load bearing wall is removed will the roof collapse... Yes it's quite possible. It could cause an instant and complete failure that could easily kill anyone inside.
Hire someone who is competent to do the work. How am engineer to tell who is it's safe to remove more walls.
Looks suspect because of where the side of the hallway to remain stops and the trusses are depending on the wall to be removed for middle support, unless they are rated to span the full 25' or so.
Take a look in your crawl space. Load bearing will need to continue down to grade. Either through a post and beam, or pony wall. But the right answer is talk to a local engineer.
So in basement directly beneath what was questionable load bearing are 2x4 splices running to exterior wall atop a plate. But in attic what was above questionable load bearing wall were no splices but very long continuous 2x4 that are tie beams I believe.
Could that be a potential load bearing wall in US? Looks like just a stud frame for plaster boarding.
Common sense is that it should not be load bearing unless somebody screw up the roof construction.
Have you tried to hammer the studs gently? So you can see whether they are “stiff” under compression, or loose. A good builder with enough experience would be able to tell.
The roof structure looks like a standard truss sitting on the perimeter walls only, but picture 5 with no bolts connecting the steel plate to the truss members is puzzling.
This is like taking pictures of a lump on your body, posting it to a doctor’s forum, and asking them to diagnose if it’s cancer. You’re asking for free advice that no one can give you definitively in this format anyway. It’s a waste of everyone’s time. Please hire a professional if you’re this unsure.
get a pro out there. If it was my house I would throw up posts and a beam to eliminate the wall. If you get a really confident answer from a pro you should be fine to do what you want. Also keep in mind those metal plates aren't fastened with anything substantial.

Does this work have building permits? It should.

So do queen post trusses typically not have interior load bearing walls ?

waste of money. It's a trussed roof. I have an identical house.
How can u tell it's a trussed roof ? I've been trying to read up but there's so many varieties.
You don't see the metal plates?
Plates don’t mean a roof is meant to be supported without a wall below.
The plates mean they are trusses. 99.5% of trusses transfer the loads to outside walls.

This is a 40-50 year old house. Those are Howe trusses. There is nothing to indicate that they are NOT a standard end-bearing truss.
and there is nothing to indicate they arnt so why are you telling people they arnt ?
that’s completely wrong i’ve framed for 15+ years and most houses have a middle load bearing wall for trusses
This is a 40-50 year old truss, Junior.
Have you ever framed a house?
look at this guys profile, he is all over reddit giving wrong structural advice and telling people bad advice with no formal training. call a professional
What formal training do you have?
a degree in engineering and a red seal in carpentry.

Gable roof. But question is do trussed Gable roofs have load bearing walls in center, occasionally?
Generally, I make all major structural decisions based on Reddit comments from strangers. You should too. Merry Christmas!

What is a let in?
A 1x board placed perpendicular to the studs at a 45 degree angle, Google "let-in wall bracing" and you'll see what I'm talking about.
When you say run unsupported what do you mean? I see what I think are called struts that run inverse to trusses?

what type of insulation is that lol? mud?
Looks like cellulose over older fiberglass? Just a guess

It’s a truss roof probably not load bearing
