Have a 2 story house. The upstairs is very open with a loft, 1 bedroom and a bathroom. The loft looks down at living room. The living room ceiling is about 20 ft high so it is very open. The upstairs stays about 10 degrees hotter than downstairs. Have plenty of soffit vents but only small gable vents, maybe 12x18 in. No ventilation on the roof itself. I know it needs some but hate to add any untill I have to put a new roof on.
My question is do gable fans work well. Have thought about putting one in to help keep attic cooler. Would this help or should I do something else?
