The terms roof and ceiling are used interchangeably by some thinking of them as one and the same thing.

These products are applied to the ceiling to decrease thermal conductivity through the ceiling. See the department of energy s doe ranges for recommended levels of insulation below. Insulating in and around your roof attic space also prevents long term damage from moisture build up or ice damming which results from the warm air trying to escape through the apex of the roof but instead heating up the snow.
