Roofing Barndominium Build - OSB size?

[airman89]

Looking for some opinions to see if I’m on the right track. I’m building our house, it’s a post frame construction, 50’ trusses spaced 4’ O.C., purlins are 2’ O.C., I plane on going 1/2” OSB with clips. Is this sufficient, lacking, or could I go 7/16” OSB and be ok?

Thanks everyone,

Adam

Where do you live and what are the snow loads?

Shingles or metal?

If shingles, do you care if the panels sag and telegraph?

Sorry I was lacking some information. I’m in Mansfield, OH and snow load is 20 psf. I’ll be going with standing seam metal.

Haha, well technically no, it’s .469" OSB, but they round up.

Standing seam isn't going to telegraph like shingles so it should be fine. Rosin paper in between?
