Visible gaps in roof from attic.
The hot air will travel the path of least resistance to make its way out of your attic.

Baffles placed in this area channel intake air into either the attic space or vent chutes and also prevent insulation from falling into the soffit and blocking airflow.
The success of a vented attic or roof deck relies on its airtightness.
This material should have extended all the way to the bottom ends of the rafter joists where the roof deck meets the fascia board basically the area where the gutters are hung.
The roof decking is left slightly shorter than the rafter ends creating a gap between the roof and the gutter.
Radiant barrier foil question.
I m installing atticfoil radiant barrier using the staple up method.
Unfortunately in most homes this is not the case.
