How can I raise my garage ceiling to add 4 post car lift.. rafters and joists..
I have an old home that has an attached single car garage. The roof has rafters with ceiling joists in the garage. The rafters and joists run from the garage door opening to the back of the garage. I will have to crawl into the attic above the garage to measure the pitch. I want to put in a 4 post car lift in the garage and will need to raise the ceiling. My understanding is the ceiling joists prevent the roof from pushing out the walls of the garage. I would have to remove the ceiling joists in order to get the height I need in the garage because a car would be in there up high 365 days a year. What would need to be done in order to accomplish this to compensate for removing the ceiling joists?

I think you are talking about a major construction project but... you might get lucky. Since we don't know what structure you've got, how much additional height you need or the dimensions of the garage we can not offer any definitive answer.
One option would be to hire a structural engineer and they could figure and just as importantly for the resale value and insurance protection of your home that a change can be made. They might come up with a solution where the rafters can be replaced by collar ties. This would give you some height and most of the additional height would be in the center away from the roof pitching inward. You could also contact your local building inspections dept. to see if a modification like that could be approved without an Engineer's stamp and signature. I doubt it but you might get lucky.
Another option would be to raise the roof. Cut the roof free from the walls. Jack it up and support it on cribbing. Extend the existing walls and set the roof back down.
