Any halfway competent contractor or handy homeowner can do this. It is not that difficult. You just need the electrician to place the outlet correctly, and to get the right size roof boot. That roof hole is what many ”handy” type contractors do not want the liability to do, so you may need a roofer for that part.

And just in case that damper is shipped upside down, be sure that it opens toward the outdoors.

Thank you. Can it vent toward the side wall instead of roof? That’s what I have setup right now

If you want any extra confirmation, you might contact Ventshood directly and I bet they could easily steer you to someone familiar with the brand given how large a player they are in ventilation. Actually , I think they specialize in venting and nothing else. If you do a search on AJ Madison for example, hundreds of models show up under their brand.
