almerc asks,
My power attic ventilator fan has died after 22 years. I had a new roof put on 6 years ago and I now have ridge vents on both my hip roof and gable roof. My soffits are well vented. Is it worth replacing my roof fan on my hip roof? I am thinking it might be a good idea since the ridge vent on a hip roof is not very long. I have heard conflicting theories about this. What about a power roof or gable vent on my gabled roof? Thank you for your help.
