Hot in summer, cold in winter: the room over the garage

A room over a garage sits on top of a space that's barely heated in winter and stuffy in summer. The garage ceiling is that room's floor, and it's easy for it to end up with gaps or thin insulation. The result is a room that never quite matches the rest of the house, no matter where the thermostat is set.

Garage air under the floor is what you're feeling

Most rooms have heated space on at least one side. A room over a garage has unheated garage below, the attic above, and often outside walls on two or three sides. The floor is often its biggest cold surface. Heat leaves through it in winter and comes up through it in summer.

Air leaks make it worse. Gaps in the garage ceiling let garage air move into the floor space under the room, bringing the cold or the heat with it.

Insulation alone doesn't stop air moving around it. That's why Abraham's approach here is air sealing plus insulation, so the insulation is doing the work instead of sitting in a draft.

Have Abraham look at the ceiling under that room

Tell him how the room behaves in July and in January. He'll check the garage ceiling and tell you how he'd seal and insulate it for your house.

Five signs the garage ceiling is the problem

  • The floor is cold to bare feet in winter.
  • The room is hotter in July and colder in January than the rest of the floor.
  • You can smell the garage in the room.
  • The furnace or AC runs and the room still doesn't catch up.
  • From the garage, you can see gaps, sagging insulation or bare spots in the ceiling.

If the room doesn't improve the way you agreed

If the job doesn't make the improvement you agreed on, Abraham comes back and reworks it at no extra cost.

In very hot or very cold weather, his infrared camera can also show where that floor is losing heat. It isn't needed on every job, but on a room like this it can show whether the heat is going out through the floor, the outside walls or the ceiling above.

Garage ceiling and bonus room questions

What type of insulation goes in a garage ceiling?

It depends on the garage and what's above it, so Abraham decides once he's seen it. Either way, the job is air sealing plus insulation.

Do you insulate garage ceilings with no room above them?

Yes. Abraham does plain garage ceilings as well as the ceilings under rooms.

Will insulating the garage ceiling warm up the garage?

Not much, and that's the point. Sealing and insulating the ceiling keeps the room above closer to the rest of the house. The garage below stays about as cold or as hot as it was.
