Whole House Fan Question...No Attic

I have had several WHF's and been generally very pleased in our dry Colo climate. My current house has no attic. Does anyone manufacture a direct vent fan that would mount on a 1/12 roof?

Your cheapest option would be a window mounted whole-house fan. Here is an example:

Air King 9166 Window Exhaust Fan - Optimized Cooling & Circulation - New 046013380203 | eBay

Here's another option, however, it seems a little weak, CFM-wise:

Indoor air quality, whole house fans, exhaust and ventilatio

I think your best bet would be to have a proper roof curb installed, and install a commercial type roof exhaust fan. The downside is this won't be cheap.
Good luck!
