Roofing Ventilation Systems

All you need to know about roofing ventilation systems from Ridge Valley Exteriors. Roofing ventilation systems are a critical part of any roofing system. They help prevent dangerous moisture buildup and keep the attic free of excess heat, which can lead to structural damage, including roof leaks. If you have an existing roof ventilation system, it’s important that you understand how it works and how to maintain it properly.

What is Roof Ventilation?

As its name suggests, roof ventilation is the process of bringing fresh air into a home through the roof. This allows hot air to escape from the attic and prevents moisture from building up in the insulation and potentially leading to mold growth. Because of this, it’s important that your home has adequate ventilation before you install new shingles or siding. This will ensure that your new installation doesn’t cause problems with moisture buildup or poor air circulation in your attic. 

Types of Roofing Ventilation Systems

There are several types of roof vents available, but there are four main categories: gable-end vents, ridge vents, mechanical vents, and soffit vents. Each type has its own pros and cons, so if you’re looking to install a new roof ventilation system, it’s important to know the different types available so you can choose one that meets your needs.

Gable-End Vents

A gable-end vent is an opening in the upper part of a wall that allows air to circulate through the attic space. It’s typically placed high enough up on the wall so that any water that accumulates in the space won’t drain back into the house through it. The most common type of gable-end vent is an aluminum louvered panel (also called a drip edge), which can be painted or stained to match your home’s exterior color scheme.

Ridge Ventilation

A ridge vent is a metal pipe that runs along the peak of a roof. It can either be made from galvanized steel or aluminum, depending on your preference. Ridge vents are installed about halfway up the ridge line — that is, halfway between the peak and front edge of your roof — where they can draw in cool air from outside and push it through your attic space before releasing it out through an outlet vent near the back edge of your roofline.

Mechanical Roof Vent Systems

These systems use fans or blowers to increase airflow through the attic space, which helps prevent moisture build-up and mold growth. This type of system is most often used during construction or after a new roof has been installed on an existing home.

Soffit Vents

Consists of screened vents placed along the eaves of the house. These are often found on older homes that do not have gable end vents. They can also be added to new roofs during construction or retrofitted onto existing roofs as needed.

If you’re thinking about installing a ventilation system in your home, you need to know that not all attic vents are created equal. The type of roof you have, as well as the square footage of your attic will help determine the type of vent that is recommended for your home.

The purpose of roof ventilation systems is to ventilate the attic to:

• Prevent moisture buildup inside the roof assembly.
• Improve the air quality in your home.

• Reduce heat buildup in the attic; and
• Extend the life of your roof.
