Upgrade to garage joists
I am looking to upgrade the celing joists in my garage for a room conversion.
Currently have 2x4, 48” OC spanning the entire 22’ length of the garage, supported midway with a perpendicular 2x6 on top.
I need to support ceiling drywall and light storage on top.
I am thinking of replacing with 22’ 2x8s, 24” OC (to match up with the 24” OC rafters.) A friend mentioned that I might have trouble getting 2x8’s that long and might want to tie shorter pieces of lumber together to create this span. I am not sure how to do this properly and ensure that these beams still have enough tensile strength for the roof load. Are 22' 2x8s difficult to get?
Looking for recommendations.
