Hello,
I am looking for ways to detail this area. As you see in the pictures, if I put the GAF Snow Country ridge vent right into the valley (per GAF instructions) I will have a triangular void (outlined in light blue on the pictures) under the cap shingles, and I think that is a bad thing.
If I cut the end of the GAF in a point to fit closer into the space I will destroy the insect screen, not good either.
I suppose I could warp and bend the end of the GAF to sort-of conform into the valleys but that would put a lot of stress on the GAF and I would expect it to crack later on.
The thing done locally is to stop the ridge vent a few feet away from this area, let the cap shingles drop down from the GAF, right onto the ridge roof deck (leaving a dip) and then transitioning up into the main roof plane.
Is the local way the right way, what are the other choices?
The pic with the strings up the valley is my trick to keep things straight, and not nail into the copper. I premark and precut each shingle before I nail it up, and I am always working out of the valley with a full shingle.
Thanks for any help!
Regards, Buzzy
