Ranch 1959 home. Soffit vents present but no ridgevents. 75% of ground floor airsealed in attic. Home in GA.
I plan on re-roofing the first chance I get which may not be until next year. I'm not sure why I hadn't noticed this in the 3 years I have lived here, but there are soffit vents but no ridge vents or gable vents. Which has me wondering, should I put in a power vent with a dual humidistat/thermostat since it won't be a while until I am able to replace the roof? Or should I just wait the additional time until I re-roof and add ridge vents and soffit baffles?
I will install everything myself, so part of my question involves cost, that is, would installing the power vent reduce the attic heat, thereby lowering home heat transfer, enough to justify its year long use? I have a shed I could install the power vent into once I am done with it.
