Hey, I've just bought a 70s single-story house with a basement and I'm planning to move the kitchen to create an open floor plan with the kitchen and living room. The roof has a 15-degree slope with concrete tiles and a snow load zone of 2.0-2.5.
Now to my question, I want to demolish the load-bearing inner wall that the red arrow points to and would need help with deciding what dimension I should have for a glulam beam.
Ideally, I want to open up the entire wall with a span of 4538. I've been considering 115x270 or 140x270, is that too weak?

It depends a bit on the load above, whether it's an upper floor or just a roof, for example (and then it depends on the snow zone as well).
But 66 + 270 or 90x 270 appears to work for roofs (in snow zone 2) and for floors according to the design guide at least

It's just the attic above, so the glulam beam will be up against the rafters.
