Is this a plumbing vent stack?

Is this a plumbing vent stack on a TPO roof? It’s a commercial building.

It’s probably some type of vent. Being commercial, I suppose there’s a possibility it is for something other than plumbing though.

Looks like a breather vent for the roof membrane.

I guess it’s a specific type of PVC roof vent. Thanks, @bcawhern1 !
