GAP in Sheeting in Valley
I am concerned about a gap in the sheeting in the valley. The concern is it has an intersecting truss that the OSB sheeting doesn’t butt up against and has a 1.5”-2” max gap in the sheeting, leaving unsupported roof decking.
the roofer did use ice and water shield (GAF StormGuard)
see the photos below, is this of concern?
To me, it looks like a bit of sloppy workmanship. I think it should be okay though. Keep an eye on it. If the shingles at the bottom of the valley start to deform, you may be able to slide a piece of flashing (metal) under the tabs in that area to support them. Or, if you prefer, do it now and worry even less.
You are going to need some good detailing at the bottom of that valley and the intersecting fascia!
Looks pretty sloppy to me. If it's not practical to fix, I'd try slipping some sheet metal into the valley, under the shingles, like 2shep says. They look like they need some support. Then I'd flash the fascia on the left like a wall. And I'd hope you have a really smart gutter guy. And I wouldn't hire the architect/framer/roofer again.
