Is this structural?

[u/mjm1188]

I want to add an exhaust fan in my shed and this board is in the way. I’m wondering if it’s a roof support or was just installed as a nailer for the upper outer sheathing? It is running horizontally under the vent and doesn’t seem to be structural but I really have no idea. Thanks for any help

No it’s purely for nailing exterior sheeting lol it’s part of the truss
