reinforcing cantilevered girder
(OP)
We have an existing W24x55 that cantilevers out 7 feet and we are increasing load on it because of a hanging partition. We are overstressing the beam by 10 percent with partition. How do we reinforce beam for negative moment with a metal roof deck directly above top flange?

I agree with Dave. 10% is not much. One flange plate on the bottom only may just give you what you need with an unsymmetrical section although I probably would go ahead with the top reinforcement to keep it more symmetrical but that will be way more than you need.
I would try to refine the loads and utilize live load reduction factors to justify not having to reinforce the beam.
