I have a question for a structural engineer. I am seeking to
I am seeking to add a supplemental structural ridge beam under a ridge board in an old garage, which has some roof sagging (3-4"). It's got 2x8 rafters, 4/12 pitch, and just a 2x8 ridge board with no rafter ties and just a few collar ties. Span is 24'. We would like to drywall the underside of the "cathedral" type ceiling. The walls are concrete block except for the triangular gable ends which are framed. We are not looking to remove anything existing, just slide in a supplemental beam as described here: https://www.youtube.com/watch?v=BMSo-avByjY&list=WL&index=6&t=0s The video shows roof trusses being cut, but we have no trusses - it just describes the method of lifting we'd like to use. My question is, what size LVL beam do we need? The supplier near me offers microlam LVL 1 3/4" thick beams in 14", 18" tall, and other heights, in any length, that are supposed to be sandwiched to make any width like 3.5" or 5.25". We do not want to add rafter ties because the vertical walls are only 7' tall and we need the headroom. … read more
