I got one of those laser temp guns, and have been checking the temp around the house.
Normal temp is around 85' wall and ceiling.
On really hot days it's 98' on the sun facing wall, and over 100' at the ceiling.
I can feel the heat coming from the ceiling.
Kind of like a broiler in the house.
We have a flat roof, false ceiling.
Just a crawl space up there.
I looked into the Quiet cool fan, but not enough room for it.
I was thinking two gable fans and more vents.
Don't really want to install insulation.
Any suggestions to try and keep the heat down.
We don't have to worry about keeping warm here.

Fans can easily pull conditioned air from the living space into the attic unless every penetration is sealed, this included places where plumbing and electrical lines penetrate the top plate. Any can lights or other electrical boxes need to be sealed from allowing air flow. If any cans aren't IC (insulation contact) rated any insulation must be separated from the can. They make caps that allow you to seal them while still keeping air flow around them to prevent overheating. The overheating problem is much less a problem when using LED lights in the cans versus incandescent bulbs. Roofs will be hot, they sit in the hot sun all day.
