Existing footing assumed without reinforcing
(OP)
If I assumed the existing footing without reinforcing steel, how can I determine the load capacity of the inverted “ T “ 4+8+4" concrete footing which will support second floor and the roof?

Concretemasonry asked you for the thickness (depth) of the footing. I take it your footing is 16" wide. If it is at least say 8" thick, the capacity will depend on the soil strength. Do you know that?

With a thickness of 9" and only a 4" projection beyond the wall, there is no bending or shear problems in the 4" wide by 9" thick extension.
The capacity will be limited by the soil capacity.
