    The company you are buying the LVL's from should have the specs for deflection and additional information dealing with this.

    I used 1 24' LVL for a 20' clear spread(9 in all across 40')(a 20' X 40' room)no or extremely small deflection and they have been in for 5 years now.

    If the roof isn't supported by the walls, what is the load?

    So is this a gabled end wall, one or two stories? We problably need more info but KBC is right about using the resources available through the LVL company. Short of a structural engineer they are about the only folks who can tell you what to use. I do not presonally calculate loading of wall, I ask the suppliers.
