I am in the planning stages for a garage build. I'd like the
I am in the planning stages for a garage build. I'd like the roof to span 34', and if possible not have any supporting posts or beam. Snow load in Toronto Canada (so not much) 3% low some roof to shed snow and rain. I'd like to be able to do some container gardening on the roof, so it needs to support s few humans walking around and some tomato plants. I'm curious about the depth of the joists and how much headroom I would loose inside if the joists aren't supported for the entire 34'. Thanks! … read more

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
