I can you tell me how strong a header beam needs to be

Customer Question

I can you tell me how strong a header beam needs to be for a single story wooden home with a composition shingle roof? The length of the beam is 14 feet. It supports 12 feet of roof to one side and 8 feet of roof on the other side. I can send you a good drawing of it.

You can plan for a 3.5" x 11.25" 2.0E LVL to limit deflection to about L/360

2.0E is the stress grade.

L/360 is the deflection as a ratio of the span.
