The Types and Styles of Roof Vents
- Box Vents:
- Wind Turbines: Also called whirlybirds.
- Power Vents: Power ventilators (roof or gable mounted) also known as PAVs (Power Attic Vents) have motors that turn large fans to drive hot air and moisture out of the attic.

- Cupola Vents:
- Soffit Vents:
Furthermore, how many air vents do I need in my roof? The rule of thumb used to determine the number of roof vents to install is one for every 300 square feet of attic area if your attic has a vapour barrier, and one for every 150 square feet of attic area if the attic does not have a vapour barrier.

Gable vents are installed in the gabled ends at opposite ends of the attic. When prevailing winds blow perpendicular to the vents, the gable vents act as both intake and exhaust. Less air exchange takes place and attic ventilation is not uniform, so it's less effective.Do whirlybirds make a difference?
Whirly birds do not do any cooling. That is: they will not lower the temperature and more than the ambient. Then just ventilate. But ventilation is better than no ventilation and if installed correctly, they can provide airflow (sucking in cooler air and expelling warmer air).Which is better ridge vent or turbine?
A ridge vent is a passive system and offers less air movement, and in moderate climates this style tends to be sufficient.

| 2001-2500 | 4 | 600 |
| 2501-3000 | 4 | 720 |
Are roof turbines effective?
They are incredibly effective at venting hot attic air, but there's not always room for them. When an attic space needs ventilation but there's no more room for ridge vents, turbine vents are usually the next best solution. They are very flexible regarding placement, and there's almost always room for them.How do you replace a ridge vent?

Do dormer vents work?
