Insulation & Ventilation Details

The way the rafters fell for the short roof over the kitchen has resulted in an enclosed cavity over top of one of the end walls. There is one rafter over the outside edge of the wall and one rafter over the inside edge of the wall. You can see the top of the concrete wall in the photo.

Once the roof sheeting is on, of course this cavity would be totally enclosed; with no way for air to get in or out. That's not really acceptable, so I've drilled some 1" holes near the tops of the rafters to allow for air to pass through.

In the photos below, the white stuff you see between the rafters is insulation, not snow. It's the same as the pink insulation that you commonly see, just made by a different company.
