Hello all, first time poster from Michigan. I am hoping someone can tell me if my idea is possible. I am not a contractor and I can’t seem to find an example anywhere. I apologize in advance if my terminology is not correct on framing members.
My current garage is gable roof. As is the rest of my house. I want to add about 12’ onto it but don’t really want to continue the gable as it the house looks long already. Is there a way to add a hip to the end to both change the roof profile a bit and get the extra length? My concern is the load On the current gable end truss. There is no ridge beam in the current garage as it’s all trusses. It seems the end truss would really take a lot of loading. It would kinda be like a Dutch gable but I want new roof to attach to peak, not a couple feet down. I hope I have explained it well enough. If it’s possible I will post in construction techniques in guess?

Perhaps since the siding continues it will look “kind of long” no matter what the roof does.
There isn't any special load on a gable end truss. I'd turn the roof of the addition 90 degrees so the new gable faces the street. That would add an architectural element and make your house look more balanced. There would be some framing to tie the old roof into the new but nothing that would be especially challenging.
Thanks for the response. I pondered this but thought I would have to extend current gable out the length of addition first before tying the reverse(?) gable into it. Creating an L shape. Otherwise I guess I would have to gable off the front and back of garage and create a T shape if you will.
You could HIP the back intersection and only have a front gable. Take a rough plan to a local truss manufacturer and ask their truss designer to mockup an estimate for you to compare the options. They will need the existing and new widths of the gables and the plate height of the garage wall. The new gable would not have to be the same peak height if you wanted to add some style. And make it come forward of, and back-across the existing front to help shorten the 'long' feel. (per zoning setbacks of course)
You could find a truss company to build a hip set to match your existing trusses.
