Condensation can happen when warm moist air comes into contact with a colder surface. Everyone who’s ever had a cool drink in an aluminum container on a warm day knows the container will become damp with condensation. The same thing might happen inside your house. Condensation can form if you have an open-air space, such as an attic or a big space between the roof panels, or the roof deck underneath. This is where having a ventilation system can come in handy. If you want to know how to vent a metal roof, here are three ventilation options.
Ridge Vents
Low-profile ridge vents are practically indistinguishable from non-vented systems and are frequently used with architectural-style roofs since they’re designed to blend in with the overall color, structure, and style of the building. The metal roofing panels are covered with venting material, which is subsequently covered with ridge cap flashing. Ridge vents are commonly used in industrial and agricultural structures and are typically 10 feet long. This is the most commonly used ventilation option for your metal roof.
Intake Vents
Soffit vents or drip edge vents can be installed at the roof’s lower edge for efficient ventilation. These intake vents automatically suck in fresh air as warm air rises in the attic, allowing for a more continuous and regular flow of air all through the whole roof system. Enough intake vents should be included to equal the desired volume of warmer flow at the ridge vents.
Gable Vents
Gable vents are commonly found at the peak of gables and serve as either an intake or an exhaust mechanism, depending on the total ventilation system in operation. In addition to the low-ridge vent solutions, gable vents are often used for housing to provide ventilation.
A metal roof is an excellent choice for both residential and commercial projects. However, it’s also crucial to ensure that the proper ventilation strategy is incorporated into your roof design.
