I've got a 16' (length) x 10' (width) saltbox-style shed that I'd like to convert into an office. The roof is supported by simple triangle trusses of 2 x 4's. Each of the trusses is cantilevered out beyond the framing about 12". This is a simple 2d drawing of the framing, shown from the side of the shed, with the chord laying on the top plates:
I'd like to know what my best options are for how to get more headroom in the space. I've thought about adding a 4 x 4 in the walls on each end of the shed and installing a ridge beam, but that wouldn't solve the cantilever problem. Collar ties would probably be sufficient for the size of this shed, if it weren't again for the cantilevers.
Could I use some sort of slider and wedge combo with plywood gussets to shore up the roof support? Or is there something else I could do?
