 Right? They look up, they're like, wait a minute. Yes. I got a huge roof and I've only got four vents. This can't be right. I want somebody to check this. But perception is not always reality. Like I was telling you earlier, the ridge vents aren't installed properly or the vents aren't, the holes aren't cut up properly in the bottom side of the decking. They're not in the right location. It's not a proper ventilation system. So you have passive, then you have active, motorized, then you have solar types of vents, attic fans. Yeah. So there's, it's the location, the right size and then balanced airflow. So. Wow.
