[Chat] whole house or attic ventilation fan on flat roof

[Eric Dymond]

I think you'd be better off upgrading your insulation, rather than ventilating your attic. Keep in mind that if you have knob and tube wiring you can't place insulation over it, as it violates fire code. The aluminized or white roof paint also helps quite a bit.

There are reportedly a few which are available for this, but its rare and a lot of folks seem to get squeamish at cutting a hole for any reason in a flat roof.    If it's one of those rare birds, I'd love to see it.
