As you begin the process of getting a new roof, you might be wondering, “What is the best roofing vent for my house?” Here are the three main types: Static, Turbine or whirlybird, and Ridge vent. Before we look at each one, know this — mixing vent type is not recommended, and all vents need an intake to work properly.
Static Vents
Static vents come in 2 different styles — a mushroom vent (550) and a box vent (750). They work independently of each other and are usually installed 1′ or 2′ below the roofline. Pros: Can be installed anywhere on the roof — gable or hip — and are economical to install. Cons: Birds can easily break through the thin screen inside a mushroom vent. We’ve seen plenty of attics with bird nests because of it.
Turbine Vents (Whirlybird)
A turbine vent spins even in minimal wind and moves a lot of air quickly. A roof that needs 12-14 static vents will only need 3-4 turbines, which means fewer penetrations and fewer chances for leaks. Best option on large gable roofs without much peak area. Cons: Over time they stop spinning — and once they do, you’ve got a basic static vent that’s harder to look at.
Ridge Vents
Ridge vents run continuously along the peak of the roof in 3-4′ sections. Pros: They blend in cleanly at the top and are the most efficient vent available. Cons: Installation cost is the biggest hurdle — all other vents must be filled in, gable vents closed off, and proper intake installed. Skip any one of those steps and ridge vents won’t work.
In my experience, the static vent is the most common choice — and for good reasons. It works. Turbine vents are fine until they stop spinning, and then you’ve got a problem. Ridge vents look great and perform well, but the installation cost adds up fast. For most Tulsa homes, a properly installed static vent with good intake is all you need.
