That’s relatively quick over a gable roof without any dormers or skylights, but If your geometry of one's roof is sophisticated — with attributes like hips, valleys, and dormers — it’s impossible to guarantee air movement by your entire rafter bays.

It appears to me to become a very durable assembly.

Back again towards the vent idea. I actually Believe venting a roof that is airsealed in the inside nicely and crafted without vent chutes is maybe the best way to make cathedral ceilings.

Finally, I kow the recessed lighting is Terrible, but what am i able to do if it is previously mounted? With one of the lights I modified it above to some pendant gentle which lowered the warmth near the roof even so the air barrier remains to be a issue.

Install rigid foam insulation above the roof sheathing and air-permeable insulation among the rafters.
