We just had trusses installed on our new home. We have 2′ overhangs on the gables and eaves with 2×6 sub-fascia and fly rafters. We’ll be using 3/4″ LP SmartSide trim for the fascia.

The crew who installed the trusses started but hasn’t finished sheathing the roof as well. They didn’t put the entire sub-fascia up before they started sheathing and appeared to make an error laying out the first run of sheathing on one side of the roof. 

On the west end of that side (where the sub-fascia) is already installed, the sheathing appears to extend the proper distance past the truss tails (2 1/4″). On the east end of that side (where there is no subfascia installed) the sheathing appears to only extend past the truss tails by an inch or less, meaning there isn’t enough room for the sheathing on that end to cover the subfascia or fascia. They didn’t install pump jacks to put the roof sheathing on, so it’s difficult for me to get up there on my own to measure, but from the ground, it’s clear that the course isn’t running parallel to the roof ridge.

On the messed up side, they only completed one run of sheathing. When I mentioned the issue to the builder, he told me that it wasn’t something to worry about and that it would “plane out.”

I’m very inexperienced here, but this strikes me as not only sloppy work but something that will result in aesthetic and functional problems for me. Am I mistaken here, or should I insist they remove the first course of sheathing on that side and re-install it?

It’s hard to photograph from the ground, but I’ve attached zoomed in photos of the east and west end of the messed up side of the roof.

TL;DR — contractors installed a first course of sheathing on one side of my roof that isn’t parallel with the ridge line and appears to scoot towards the ridge by an inch or more from end to the other. The contractors think it’s no big deal, and I’m not experienced enough to trust my gut on this which tells me that it is.
