I would like to remove some walls to open space in my house.

Customer Question
I would like to...

I would like to remove some walls to open space in my house. What information do I need to determine the size of the beam required?

Tutor's Assistant: OK. Tell me a bit more about what's going on so we can help you best.

Its a 25 ft. Span supporting only the roof.

Tutor's Assistant: Is there anything else important you think the Structural Engineer should know?

I don’t know what else to ask. There would also be dead weight from snow. I live in western New York.

The beam will span 25'?
Is this an exterior wall?
What is the city and state so I can look at Snow loading?

Lancaster, NY.
No. It’s an inside wall separating the space. There is a header now separating the living room and dining room. The kitchen is boxed in. So the beam runs parallel to the outside wall about 13 feet in. There are 3 2x6 in the middle of the span supporting the two beams.

Here are pictures with the walls in place and then removed with temporary beam with supports. I would like to remove all supports and have one beam. There is nothing but attic and roof above.
Thank you.

I will give you two sizes. One if it supports the attic only and one if it supports the roof and the attic.

Structural Engineer: StructuralEng, Consultant replied 6 months ago

If it supports the roof, you will need four 1.75" x 20" 2.2E LVL

If it does not support the roof, you will need three 1.75" x 16" 2.2E LVL or two 1.75" x 18" 2.2E LVL
