I am building a home in West Virginia. The design is cross gabled,i.e., the center section has a perpendicular section on each side. The center section is a 6/12 pitch. I am using 2x12 rafters on a 45 foot ridge beam. The dl=15psf, ll=40psf. What size ridge beam(LVL?GLULAM?MICROLAM?) do I need? Thanks
