What is a Roof Ridge Vent And How to Install?

roof ridge vent

A roof ridge vent is a device that is installed on the roof to allow air to escape. It is an essential part of a roofing system, as it helps to prevent moisture and heat from building up in the attic. In this blog post, we will discuss the benefits of roof ridge vents and how to install them properly.

Roof Ridge Vent

A roof ridge vent is a ventilation device installed along the peak of a roof. It helps to remove hot and stale air from the attic, allowing for better airflow throughout the house. It can improve indoor air quality and reduce the strain on your HVAC system, potentially leading to lower energy bills. Roof ridge vents come in various styles and materials, such as aluminum or plastic. Some are powered by electricity, while others rely on natural airflow. It’s essential to consult with a professional before installing a roof ridge vent to ensure it’s compatible with your roofing material and properly placed for optimal ventilation. Overall, a roof ridge vent can be valuable to your home’s ventilation system.

Roof Ridge Vent Installation

When you are thinking about installing a roof ridge vent, there are a few things you will need to keep in mind:

  1. You need to ensure that the roof can support the weight of the duct.
  2. You must take measurements to ensure that the vent will fit properly.
  3. You need to make sure that there is enough airflow to power the vent.

We will discuss all of these things in more detail below.

Determine if Your Roof Needs a Ridge Vent

If you are wondering if you need a ridge vent for your roof, There are a few factors to consider. First, In warmer climates with hot summers, where air conditioning is frequently used, a ridge vent can help regulate temperature and improve energy efficiency by allowing hot air to escape from the attic. Additionally, it can also reduce moisture buildup and prevent mold growth. However, this may not be as necessary if you live in a colder climate with little need for air conditioning. Another factor to consider is the current ventilation system on your roof. Do you already have soffit vents or other forms of ventilation? If not, a ridge vent could provide an essential source of airflow. Ultimately, the decision comes down to your climate and current ventilation system, but installing a ridge vent can bring numerous benefits in regulating temperature and preventing moisture damage. Consult a professional for personalized advice.

Preparing for Ridge Vent Installation

  • Check the condition of your current roofing. If your roof needs repair or replacement, it’s best to take care of this before installing a ridge vent. Not only will this improve the overall look of your home, but it will also extend the life of your new ventilation system.
  • Choose the right product for your needs. There are many different types and styles of ridge vents on the market. Make sure to select one that is compatible with your roofing material and has the appropriate weather rating for your climate.
  • Gather the necessary tools and supplies. You will need a ladder, drill, screw gun, screws, caulking gun, and sealant for installation.
  • Begin by removing the old ridge cap. It can be done with a pry bar or hammer. Be careful not to damage the roofing material beneath the lid.

Calculate the amount of ventilation you need

The air quality in your home needs good ventilation, but how do you know how much ventilation you need? One way to calculate this is by measuring the size of your space and its calculation factor, which considers variables like insulation and whether or not your home has gas appliances. Once you have these numbers, you can use an online calculator or a simple formula to determine the amount of ventilation needed. It’s also helpful to pay attention to signs of poor air quality, such as stale smells or excessive dust. If you notice these issues, it may be time to check your ventilation and ensure it’s up to par.

Purchase and Install a Ridge Vent

Once you’ve determined that you need a ridge vent, the next step is to purchase and install one. It can generally be done by following the instructions provided with your purchase, but there are a few general tips to keep in mind. First, ensure the ridge vent you select is the right size for your roof. It should extend the entire length of the ridge, with a minimum width of two feet.

Next, you’ll need to install baffles on either side of the vent. Baffles help direct airflow and keep out pests and debris. They should be installed along the entire duct length, spaced about two feet apart. Once the baffles are in place, you can install the vent itself.

Start at one end of the ridge and nail the vent in place. Ensure the nails are driven into solid support, such as a rafter or truss. Work your way down the length of the ridge, nailing the vent in place every two feet or so. Once you reach the other end, your roof ridge vent is installed!

If you’re installing a ridge vent on an existing roof, you may need to install additional soffit vents to ensure adequate airflow. Soffit vents should be installed at the eaves, spaced evenly along the length of the building. For best results, consult a professional before installing a roof ridge vent.


Roof ridge vents are essential for the health of your roof. They allow air to circulate and prevent moisture from building up, which can lead to rot and leaks. If you don’t have a ridge vent, it’s time to install one. Follow our step-by-step guide to ensure that your installation is done correctly.

Storm Pros provided a great service with my short notice call. They repaired the roof where it needed fixing and other minor lifted areas. Case took the time to come by my home to ensure the roof was fixed prior to potential rain! I will continue to do service with them and highly recommend them.

Storm pros are excellent. Once I contacted them they were right on top of the issue. I had a leak from my roof vents and not only did they come out next day - they even went out of their way to check the weather forecast to see if we had any rain. Case was easy to work with. They ended up fixing the issue with my leak in my roof in under 30 min. Hands down the business to go to with any roofing needs.

When I sent a request for a quote, I received an immediate response. Case was able to set up an appointment within a few days and I had a quote within a few hours after the appointment. They were able to come back within a week to perform the installation and I couldn't be happier with the work. Case followed up with an inspection of the work to make sure I was happy with it and that it was done properly. I highly recommend Storm Pros!
