Roof ventilaton - hip roof (ridge vent, fan, power vent ?)


The house has a gable roof over the garage (gable vent on driveway end) tied into the hip roof over the main part of the house.

The roofer installed a ridge vent across both the gable and hip sections of the roof . He left the power vent (near the peak of middle of the hip roofed section ) the but told me to disable it which I did. However, the attic seems to be hotter than before. What are my options here ( run the power vent, add some more passive vents ("turtle back") on the hip roof fairly near the ridge etc ?

- Thanks

For ridge vents to work properly, there must be an equal volume of air supplied by soffit vents. It has been a while since I did roofing, but since hip roofs come to a point, I would install a Whirly Bird vent at the peak. This lets the hot air out at the top. You would still need soffit vents.

I have soffit vents but believe that the amount of ridge vent area for them exhaust through is less . I have used the tubines on other houses in the many years ago past and have found them to stop rotating after fairly short period of so that's why I though about just installing the passive vents ("turtlebacks ").
