The attic in most properties was a room that was largely forgotten and thought to be useless. Homeowners are, however, now looking for ways to maximize their indoor living space, and the attic is one of their go-to options. Here, you can have a guest bedroom, library, playroom or family room. Decorating the room to fit your intended use is nonetheless only half the equation in turning the attic into a livable and comfortable space.

You will need the right metal roofing design for your Utah property to maximize the living space you get. Gambrel roofs are the leading roof designs for those looking for maximum floor space and headroom in their attics. Flat, gable and domed roofs can also suffice. Other than the roofing design, you need a suitable roof vent to avert the accumulation of moisture in the attic and keep air flowing through it as it should. The following are the roof vent options that will suffice for attic ventilation.

Box Vents

These are also called louvres, turtle vents or low profile vents and are static vents meaning they comprise no moving components.  Box vents are installed over holes that will be cut in your roof. They use natural convection for the hot air that will naturally rise and escape through them. These vents come in various colors and are most effective when installed closest to the roof ridge. Their efficacy is however limited in ventilating an entire attic, and you might need several box vents for optimal attic ventilation.

Wind Turbines

These are shaped like a chef’s hat and are also called whirlybirds. They rely on wind power to move air into and out of your attic. Turbine vents offer higher ventilation levels compared to box vents and come in varying degrees of quality. You should nonetheless invest in those with permanently lubricated ball bearings or plastic bushings in their spinning mechanisms. Most people associate wind turbines with squeaky noises that might be scary in the attic, but this is a minor inconvenience.

Ridge Vents

These are static ventilation options and resemble a book’s spine when opened and laid face down. Ridge vents run across the whole length of your roof’s horizontal edge and blend with the roofline to generate an aesthetic appeal. You can choose to combine ridge vents with soffits vents for maximum ventilation. While other attic ventilation alternatives generate cold and hot spots on your roof, ridge vents have even temperature distribution and are unaffected by weather changes.

Soffit Vents

These create a means of air intake into your roofing’s ventilation systems. They are installed in the eaves and soffits and often made of aluminum or PVC. Soffit vents are generally used with other vents like small gable-end vents to maximize the airflow in your attic. They are highly effective for attic ventilation when combined with continuous ridge vents.

The above ventilation options feature seemingly complex designs and should also be expertly installed. Thankfully metal fabricators now use different techniques to customize the ventilation attic products to match your home’s roof. You are thus guaranteed that the vents and wind turbines will not become the primary source of leaks in your roof.
