You know that you need to have proper roof ventilation for your property, but is it possible to have too much of a good thing?

In short, yes.

There is a fine line between appropriate and excessive ventilation. In this article, we will help you understand what the proper amount is, what types there are, and how it can be dangerous to have too much.

The Importance of Proper Roof Ventilation

In the humidity of Louisiana, you know how sticky things can get. Your roof and home will be adversely affected by the weather without proper ventilation.

You want to be sure that air is circulating so that moisture doesn’t build up, causing further damage down the road. The shingles can be damaged, wood can rot, mildew and mold can take over, and warped areas can cause leaks.

With good air flow, the life of your roof and your shingles will be increased, saving you a bundle of cash. Furthermore, your attic area won’t get as warm in the summer so your air conditioner will run less and you will save on energy bills.

A cooler, drier, well-ventilated area is the only way to prevent wood rot, mold, mildew, and other costly damages to your new, or like-new roof. Even if you have had your structure in place for a while, it’s a good idea to have our pros at Juneau Odenwald Roofing do an inspection to make sure you’re still in good shape.

Types of Roof Ventilation

There are several different types of ventilation options on the market. Let us help you discover their individual functions, & which one is right for you!


A soffit vent is installed underneath the roof’s eaves. The air comes through the eaves and then goes out through peak vents at the top. Screens have to be installed at the openings to keep out bugs.


Static vents are also called louvered or turbine vents. They go on top of the roof and are cheap to put in.

You just have to make sure the installation is done right so there aren’t any leaks.


Warm air is allowed to rise up and escape through the highest point with ridge vents installed in the roof peaks.


Electric or solar powered vents come with a thermostat that tells the system when air needs to be circulated. Some of these can also be powered by wind.


Gable vents look like vertical triangles &  are put in along the apex if you have a pitched roof. Warm air gets out without allowing moisture back in.


With a power switch or a thermostat installation, an attic fan can be turned on to let hot air from the attic out.

Wind Turbine

A wind turbine catches the wind and spins a fan, which pulls hot air outside.

Dangers of Too Much Ventilation

The two main dangers associated with too much ventilation involve roof damage and increased utility bills. If you have too much air circulating, your roof will collect moisture causing damages that will weaken spots and then cause leaking.

During the warmer months, your air conditioner is going to kick into overdrive to keep up with the warm air that comes in from the outside. You’ll see a huge difference in your energy costs after getting the ventilation completed properly.
