Customer Question

We added an addition to the back of the house and want to open up the wall between them. This is the existing load bearing wall that supports the roof rafters. the rafters and ceiling joists are both 2x6. the opening will be 10' 6" and I will be supporting 7 rafters and 7 ceiling joists on the header. What size lumber should I use to build this header?

Will it support an attic and roof from both sides? What is the joist length on each side of the beam?

What is the city and state so I can look at snow loading?

Customer: replied 1 year ago.
It will just have the 7 joist/rafter pairs hanging off the side of it. I am in Indianapolis, IN

I need the lengths on each side of the beam.

Customer: replied 1 year ago.
It is 15' to the ridge pole of the old roof. The addition extends out 13'. The addition was added on as an ell so most of the weight for that roof is supported by the new walls.

You can plan for a 3.5" x 11.25" 2.2E LVL

or a 5.25" x 11.25" 1.8E LVL

or a 4 - 2x12 doug-fir no. 2.
