Can half the tree is dead and the other half looks fine be fixed without removing the tree?
Often yes, and of everything on this list this is the one that most deserves a real inspection before a saw comes out. If the cause was a single finished injury and the remaining canopy is vigorous, crown cleaning to remove the dead wood plus attention to soil, mulch and water can hold the tree for many more years. If it is an advancing vascular disease or progressing root decay, the dead fraction enlarges every season and removal is the honest answer.
How long you have to decide
Watch, and measure rather than worry. The number that matters is whether the dead portion is larger this spring than last — photograph it from the same spot each year. Holding steady across two or three seasons means the injury is finished and the tree is compensating. Visibly expanding each year means active decline and a closing window. Independent of that verdict, the already-dead limbs will keep breaking loose and becoming hangers, so they should come out on their own schedule.
