Roof Ventilation is vital for keeping your home cool and mold free. Proper ventilation removes excess heat, moisture, and stale air from the attic space, keeping your roof healthy and reducing energy costs. But not all roof vents are created equal, and which one is best for your home depends on many factors, including the pitch and slope of your attic and where you live.
Gable vents are a popular option for homeowners who want the benefits of roof venting but prefer a more aesthetically pleasing solution. Installed in the gables (the triangular sections at each end of a roof line) they allow for efficient air flow up through your attic and can be painted or stained to match your home’s exterior.
Ridge Ventilation
Because of the way that they are designed, ridge vents are able to take advantage of the natural movement of warm and cold air in your attic. Hot air rises and, when properly vented, ridge vents are able to release this hot air quickly. The design of ridge vents also provides added durability and protection from snow build up that can interfere with other roof vent styles.
Like gable vents, ridge vents can be installed in the gables of your home, or in the eaves. They allow for effective air movement and provide a more aesthetically pleasing solution, as they can be painted or stained to match your attic trim and siding.
They are especially beneficial for homes with dormer windows as the soffit vents that would normally be required to allow for adequate roof ventilation are not present. In addition, the ridge vents can be used to balance the chimney effect that would otherwise result in a reduced flow of attic air when venting from the bottom of your attic to the peak.
These vents use the natural movement of air and are designed with louvers or slats that open when it is time for your attic to breathe but close in the event of rain, snow, or other precipitation. They are a great choice for most climates as they offer the best combination of ventilation and moisture control, keeping your attic cool while helping to prevent water leaks down into your living spaces.
They are a good choice for most climates as they offer the least resistance to the flow of air and require no electricity or mechanical assistance. Their design also provides the least amount of moisture resistance when compared to other types of roof vents, but this can be offset by installing a shingle over the top of each vent for additional water protection.
Unlike other roof vents that rely on the natural movement of wind or a fan for operation, whirlybirds need a constant source of wind in order to rotate and pull attic air through their aluminum blades. While this works well for some houses, in others it can be less than ideal due to the lack of wind.
