BEST ROOFING VENTS PROS AND CONS

As you begin the process of getting a new roof, you might be wondering, “What is the best roofing vent for my house?” We’ll take a look at the 3 types as well as the pros and cons of each:

1. Static

2. Turbine or whirlybird

3. Ridge vent

Before we look at each type more in-depth, it’s important to know that mixing roof vents is not recommended. Also, to work effectively, all roof vents need an intake to fully work properly.

Static Vents—Static vents come in 2 different styles—a mushroom vent (550) and a box vent (750). These types of vents work independently of each other and are usually installed 1’ or 2’ below the roof line.

Pros—Static vents can be installed anywhere on the roof, and since they work independently, these vents can be installed on gable roofs and hip roofs. Static vents are economical to install.

Cons—One of the biggest issues with the mushroom (550) is that birds can easily break through the thin screen inside the vent. There are many cases of birds building nests inside of attics after having gained access to them through the mushroom-style vents. Another factor to consider is that a roof requires several of these vents. The problem that can arise with installing many vents is that leaks can occur if the vents are not installed properly.

Turbine Vents or Whirlybird—A turbine vent spins even when there are minimal winds, hence the word “turbine.”

Pros—Turbine vents can move a lot of air and can move it quickly. Also, a roof that needs 12-14 vents will only need 3-4 turbine vents, lessening the chance of leaks. Turbine vents are extremely efficient and are the best solution on large gable roofs that don’t have a lot of area at the peak.

Cons—Over time, turbine vents can stop spinning. Once the vent stops spinning, it then becomes a basic static vent and loses its effectiveness. Many consider turbine vents to be an eyesore since they sit high up and spin.

Ridge Vent—Ridge vent sits on top of the roof and comes in 3-4’ lengths. Ridge vent is cut on the peak of the roof and is continuous on a roof from end to end.

Pros—Looks is what most people like about ridge vent. It blends in at the top of the roof and creates a clean look. Ridge vent is the most efficient vent out of all the vents. Since plywood is cut continuously from edge to edge at the peak of the roof, this creates an equal balance of air movement throughout the entire attic. Since ridge vent is installed at the top, it eliminates most leaks that can occur with vents.

Cons—Price is the biggest con with ridge vent. In order to install it, all other vents must be filled in. Also, gable vents must be closed off, and an adequate intake must be installed. If any one of these guidelines is not followed, ridge vent will not work and will be a waste of money.

When considering the best type of ventilation to meet the needs of your home, the most important matter is that your roof receives adequate ventilation. Your contractor should follow the 1/300th rule to make sure your roof is properly ventilated, thereby maximizing the life of your shingles.
