 there's going to be a very strategic place to place an attic fan or multiple attic fans. And that would be, I mean, again, having a roofing contractor that knows what they're doing and knows what they're talking about will be able to place that in for you without conflicting against the other ventilation that might be nearby. But really, I mean, it comes down to if you need to ventilate your house a little bit better, attic fans, especially solar attic fans, that way you're not paying to actually ventilate your roof. You can do it through solar power.
