I'm looking at replacing an interior load bearing wall in my home. It is 18' long, and I live in the south so there is no need to worry about snow on the roof. This is only a single story house with a small attic space above it. Above the load bearing wall are supports for the roof that jut out in 45-60 degree angles to support the roof.

I called 4 local hardware stores (3 of which are "big box" stores), and explained what I had. All 4 told me that a single 1-3/4" x 11-7/8" LVL beam is adequate. I was discussing this with a friend at work, who thinks this is terribly wrong. He called a local lumber company, who stated that I need a 18" LVL beam to make this work.

At this point, I'm looking to get some opinions. Will the 11-7/8" beam be adequate? If I do need something a little bit stronger, can I just use 2 of the 11-7/8 beams?

We are trying to get away with the smallest beam as possible, as we are trying to preserve as much head room as possible. Thanks for the help!

Have a think about:
i) recessing the beam into the truss work - a bigger beam need not impinge on your headroom.

ii) a column (or two). Big impact on beam sizing. For example, depending on your functional requirements you could locate furniture near a column, incorporate lighting (or other services) into it, and not have any problems with thoroughfare.

1st of all....for something this critical never...I repeat NEVER!! ask the opinion of someone at the BIG BOX store...they could have been selling stereos the week before. No offense to those who work in the business.

Spend a couple of hundred dollars for an Engineer to come into your house and look at your situation.

If your in the south...don't you have hurricane guidlines to follow?

Just my opinion

Good Luck

I called around today and talked to some lumber yards. Two of them had in-house engineers. After I faxed them a rough drawing with dimensions, they told me I could do a (4) 14" x 20' LVL beams, (3) 16" x 20' LVL beams, or (2) 18" x 20' LVL beams. I ended up deciding on the 14" beams, and I have a contractor lined up this weekend to help install it. Thanks for the info!

Lord knows what the people at Lowes & Home Depot were looking at, but they were way the heck off on measurements.

It also gives you some piece of mind that you have the input from some real pros.

Good Luck
