Cantilever Roof Sag


Hello,

I own a small ranch house with an attached garage. The exterior wall of the garage is inset 4ft from the exterior wall of the house. The roof over the garage cantilevers out 4ft and has the same roof line as the house. The cantilever part of the garage roof is sagging and i suspect the reason is the load bearing wall is inset 4ft from the heel of the roofing truss. The roof trusses on the house and the garage are all the same. To remove the sag from the garage roof can i simply jack it up level and add a vertical support directly above the wall between the top and bottom chords? If not what is an acceptable practice to repair this type of issue?
Thanks

That might just do the job---also --sistering in 2x4s along side the upper chords under the roof sheeting might be needed---post a picture or two---

I would post pictures before doing any work. Size/number of fasteners, size/thickness of plywood gussets at the new bearing point, etc.

I agree, need pictures. If you do have trusses with 2X4s, a cripple above the plate trying lift all the load of the roof may just put a hump in the rafter part of the truss.
