I am working on designing a home to build in the spring. The home has a cathedral ceiling sideways in the center. It will be a front to back of the home span of 39′. Do I need to use an I-beam, rectangular steel beam, wood beam or…? The roof pitch is about 1:4 as I recall, and the room width is 26′.
Any suggestions would be helpful.
Thank you in advance,
Heinrich

What you need is an engineer. A structural engineer can tell you exactly what you need and guarantee that it will hold up your snow load, etc.
Many lumberyards also have someone trained to use their vendors eingineered wood beams software. If you give them roof pitch and all dimensions they can spec your beam. My local yard even supplies an eingineers stamp- as long as your purchasing from them.
If you are thinking of a truss roof, they will do all of the figuring for you, goodluck, bob
I was thinking of a structural ridge pole made up of LVL's.
You are going to find out that a structural ridge beam 39' long is tremendously expensive. You may want to think about a steeper roof pitch so the structure can be trussed with the cathedral at 4/12
