Installing a metal roof is one of the best investments you can make for your home, but if you have never had one before, there is a lot to learn about. Will it attract heat? How long will it last? What kind of maintenance does it need, and what type of venting is required? How do you choose the right ventilation for your roof?
Here we’ll discuss your metal roof ventilation options.
In the Pacific Northwest, we know what it’s like to have plenty of moisture. However, condensation is the real issue to be considered when venting your metal roof.
When warm air comes into contact with a colder surface, you’ll see condensation. And if you have an open-air space in your home, such as an attic or areas between the roof panels or roof deck, condensation can build up.
You don’t want that to build up for long, as it can allow for mold growth and even dry rot.
Having the right ventilation on your roof will ensure that the warm air from the space is removed before it has the chance to create condensation.
The two most common types of vents for metal roofs are ridge vents and gable vents.
Ventilation Types of Roof Vents
Here are three of the most common types of ventilation types used for roof vents.
- Ridge Vents
- Gable Vents
- Intake Vents
These vents are hardly noticeable and are designed to blend in with your home’s color, shape, and overall design.
The vents are simply placed on the metal roofing panels, then covered with ridge cap flashing.
They are usually about 10 feet in length and allow for large volumes of warm, moist air to escape.
These vents are placed at the peak of the gables and work to both exhaust and intake air, depending on how the rest of the venting system is designed.
Intake vents can work with gable vented systems or ridge venting. They utilize soffit or drip edge vents. They are designed to act as an intake system that brings in cool air once the hotter air leaves the vents via the gable or ridge vents.
