While some ceilings in the southwestern part of the united states require a minimum of r 19 insulation most attics or ceiling areas require a minimum of r 38 in the ceiling.
More specifically the r value is a measurement of the insulating material s resistance to the movement of heat.
Garages are typically unheated and uninsulated.

These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.
Insulating the ceiling of your garage involves the same process as insulating the walls.
Simply put the r value is how effective the insulation is.
Here the level of r value you apply is largely going to depend on whether or not you have a finished room over the garage.
