Ventilation allows your attic to breathe and protects your metal roof system from damaging heat and moisture. It works by removing moist, warm air from the space before it has the opportunity to condense and cause problems such as mold and mildew. It’s important that your metal roof is properly vented to extend the life of your roof, regulate indoor temperatures, and reduce energy costs.
There are two main options for ventilation on metal roofs: gable vents and ridge vents.
Gable vents are passive vents that are located in the gable ends of a house. They are installed at the tallest point of a house, which allows the warm air to move outward. Gable vents are not only functional but can be decorative. Additionally, gable vents can prevent ice dams from forming on roofs.
Ridge vents are low-profile vents that are used in architectural-style roofs. They are designed to integrate with the overall color, shape, and aesthetic of the roof. these caps are made from a thin perforated strip and hidden beneath a flap of metal that is attached to the roof. Ridge vents are designed to allow air to flow freely out of the attic.
Pros and Cons of Gables Vents and Ridge Vents:
- Gable Vents are typically less expensive
- Gable Vents are easier to install
- Gable Vents can add aesthetics to your home or project
- Ridge Vents offer more ventilation than Gable Vents
- Ridge Vents are less likely to cause leaks
- Ridge Vents are more expensive and more difficult to install
Both ventilation options have advantages and disadvantages, but the right vent for your project will depend on factors such as climate, the size of your attic, and the style of your home.
