Roof Deck Seams Visible - What's Wrong?

[William J. Decker]

1) It's wrong. swelling of the roof deck.
2) 7/16 on 24" OC is just plain wrong as well (and I don't care what the local codes say).
3) looks like crap.

Run away.

I like the technical discussion, but for the purposes of a hime inspection, it's just plain messed up, non-professional construction. Tell the client that and let them make up their own mind.

Simple, really.

All the new homes here in CA are 7/16 osb 24" center and I would say 99.99% of them are jsut fine if installed right....we have used osb in our reroofs for over 15 years now and I have nerver had one issue with it...my 2 cents

Maybe I am suffering from regional bias. We have rain and snow, here. such a roof would have collapsed, around here, long ago.

Hope this helps;

Does plywood sheathing also suffer from this "edge swell" problem?

The roof deck is probably stable, but the shingles need replacement. The warranty is void and they will continue to buckle although the severity will vary seasonally. Bad contractor! No beer!
