[Spridgets] car lift

[GUY DAY]

You could try using 4 vertical sections of 4"x4" under the joists as close 
as possible to the hanging points and it wouldn't be too difficult to get 
hold of some strengthening U shaped metal sections for under where the joist 
is used for hanging.  Extend those into a metal support area side to side 
between the hanging points.  You could cut a slot into the top of the 4"x 4" 
so it holds a little better under the joist.  They would still be a pain and 
get in the way.
A normal roofing joist is not designed or constructed to take additional 
weight on point loads and like Gerard, would be very, very wary of the 
project. You may find the house insurance won't cover you for the rebuild of 
a roof if you have dragged it down yourself.
