I live in Ottawa and I installed insulation and vapor barrier in my garage. I have it heated with a gas wall furnace as well. Last winter I noticed only half of my ceiling is insulated and the other half is just drywall above. Do I need to rip the drywall down on the insulated part to install I solution and vapor barrier or is there a way to insulate it without removing all drywall? I cut a hole and there is enough room for me to fit into ceiling and insulate from top.

You could just lay out poly on top of the truss and push in batt insulation from the attic. A bit paint in the house but that how I would do it if it's we're my garage

Yes you can definitely leave the drywall as is and insulate from above. It would be best and easier to just blow the insulation in rather than install insulation Batts. Always keep in mind you need a narrow space from the exterior soffits into your attic for air circulation so just insulate past the exterior wall only and if need be installed more vents in between the roof Rafters to allow air flow.

If you can get insulation up there without taking down old drywall then you can poly right over top of drywall. this i have done myself it works.if you have polyed the walls then you can use TUCK TAPE [BLUE/RED] to seal it together. ceiling to walls it will keep out the cold
