Did My Roofer Install a Whirlybird? Need Advice

Hey everyone,

I recently had a roofer replace my Colorbond roof, and as part of our quote, we agreed to have a whirlybird installed. He sent me the final photos, but the only image that shows something protruding from the roof doesn’t really look like a whirlybird to me.

Before I bring it up with him, I wanted to check—does this actually look like a whirlybird?

And if it turns out he didn’t install one, how can I ensure it’s added properly without messing up the existing work?

Appreciate any advice!
