Hip ridge vent
I understand that venting a hip roof is difficult, because of the short run of ridge at the roof peak. I came across a product that is supposed vent the rafter bays along the diagonal hips. See the links below. Together with intake vents at the soffits, I think it would work. But I am wondering what all the slots cut into the sheathing will do to the structural integrity of the roof? I am also wondering whether anyone has experience with this product? Is it widely used? Will there be enough airflow in a 2 inch vent channel on underside of the roof sheathing so that one can effectively vent a hip roof with this ?
I appreciate any comments ! Thanks,
