Everyone knows that having some form of ventilation in the home allows for a more enjoyable indoor environment, and also helps other systems in the home work efficiently. But did you know that one form of ventilation, known as the ridge vent, is part of your roof?
Ridge vents play a significant role in achieving adequate ventilation by allowing hot, humid air to escape from the attic. This helps prevent a range of problems, from structural damage to high energy bills. In this blog post, we’ll explore what ridge vents are, their benefits, how to install them, and tips for maintaining them to ensure your home remains comfortable and energy-efficient throughout the year.
What Is A Ridge Vent?
The roof’s ridge is the horizontal line where two sloping roof sections meet at the top. It’s essentially the peak of the roof, forming the highest point. The ridge vent is named after this part of your roof, since it’s installed in this area and can run the entire length of the ridge.
They provide a continuous escape route for warm, humid air that’s trapped in the attic, allowing for better air circulation throughout the house. By creating a natural flow of air, ridge vents help maintain a balanced attic temperature and humidity level.
How Do Ridge Vents Work?
Here is how roof ridge vents work to increase the ventilation in your home:
Natural Air Flow & Ventilation Cycle: Ridge vents take advantage of natural convection. Cool air enters the attic through soffit or eave vents at the lower part of the roof. This cool air pushes the warm air up and out through the ridge vents, creating continuous air circulation.
Temperature Regulation: By expelling hot air and allowing cool air to circulate, ridge vents help maintain a balanced temperature in the attic. This prevents heat buildup in the summer and reduces moisture accumulation in the winter, both of which can cause damage to the roof and attic structure.
What Are The Benefits Of Installing Ridge Vents?
With a range of benefits, ridge vents have become a necessity in many homes. Here are the benefits that you will get when you install a roof ridge vent.
Improved Air Circulation
As we already covered, the biggest benefit of having ridge vents on the top of your home is to enhance the natural airflow in your attic. They help to expel hot air during the summer and moisture-laden air during the winter, which is very crucial in areas such as Wisconsin. This constant circulation prevents the buildup of excess heat and humidity, which can lead to various issues not only inside your home but on your roof as well.
Improved Energy Efficiency
We all know how important the concepts of sustainability and energy efficiency have become to many homeowners. By maintaining a balanced attic temperature, ridge vents reduce the load on your HVAC system. This leads to lower energy consumption and, consequently, reduced utility bills.
Enhanced Indoor Air Quality
Poor attic ventilation can lead to the accumulation of pollutants, allergens, and moisture, which can seep into your living space and affect indoor air quality. Ridge vents help reduce this by promoting better airflow, ensuring a healthier living environment for you and your family.
Prevent Roof Damage
Excessive heat and moisture in the attic can cause significant damage to your roof’s structure, including warping, mold growth, and cause roofing materials to deteriorate. Ridge vents help prevent these issues by allowing for proper ventilation, thus extending the lifespan of your roof and reducing maintenance costs.
Proper Ventilation Can Contribute To Roof Longevity
Ridge vents contribute to the overall longevity of your roof by preventing moisture buildup, reducing the risk of ice dams in winter, and alleviating the stress on roofing materials caused by extreme temperatures. This results in fewer repairs and replacements over time, providing long-term savings.

What Are The Types Of Ridge Vents?
When it comes to keeping your attic cool and dry, ridge vents are one of the most effective solutions. But with so many types to choose from, which one’s the best fit for your home? Let’s break it down:
1. Rigid Ridge Vents
Rigid ridge vents are popular for their durability and effectiveness. For homes located in areas with high winds, opting for a rigid ridge vent made from aluminum can provide extra durability and protection against storm damage. Their low-profile design allows them to blend seamlessly into your roofline, which is a bonus if you’re concerned about aesthetics. Additionally, they’re great for long-lasting ventilation and easy to install—whether you’re doing it yourself or hiring a professional.
- Pros: Durable, easy to install, low profile blends with the roof.
- Cons: May not work as well for complex roof designs, like those with lots of hips or valleys.
- Best For: Homeowners with straight, uncomplicated rooflines who want durability and ease of installation.
2. Shingle-Over Ridge Vents
If you want to enhance curb appeal without sacrificing ventilation, shingle-over ridge vents are a perfect option. Just make sure to use matching shingles for a seamless look. They are usually made from flexible materials like plastic or rubber, which makes them easy to work with during installation. While the flexibility allows for easier application, these vents still provide solid ventilation for your attic, and their discreet design is perfect for those who want their ventilation system to be low-key.
- Pros: Virtually invisible, blends seamlessly with the roofline, flexible for easy installation.
- Cons: Installation can be tricky—especially when trying to get the vent and shingles aligned perfectly—so professional installation may be required.
- Best For: Homeowners looking for a discreet, aesthetically pleasing solution.
3. Nail-On Ridge Vents
Nail-on ridge vents are the go-to option for homeowners looking for an affordable and straightforward venting solution. These vents are nailed directly onto the roof, making installation fairly simple compared to other types. They’re often made of aluminum or plastic, which provides a balance of affordability and durability. While they may not blend into the roof as seamlessly as shingle-over vents, they still offer effective ventilation for most homes.
- Pros: Simple to install, budget-friendly, effective airflow.
- Cons: Can be more visible compared to other options and may not look as sleek.
- Best For: Homeowners who want a cost-effective, easy-to-install option and don’t mind a slightly more noticeable vent.
4. Off-Ridge Vents
For homes with obstructions like chimneys or skylights along the roofline, off-ridge vents offer an excellent alternative to traditional ridge vents. These vents are installed below the peak of the roof, usually a few feet down from the ridge, and work in conjunction with other ventilation systems to improve airflow throughout your attic. While they aren’t as efficient as ridge vents on a clear, straight roofline, they’re a good solution for roofs with design challenges.
- Pros: Perfect for roofs with obstructions like chimneys and skylights.
- Cons: Not as effective as traditional ridge vents in terms of airflow, especially on a clean, unobstructed roof.
- Best For: Homes with complex roofs or multiple features like chimneys or skylights that prevent using ridge vents along the entire roofline.
How Do Ridge Vents Compare To Other Types Of Vents?
When evaluating different ventilation systems for your roof, it’s essential to understand how ridge vents compare with other options. Here are key points of comparison:
Other Static Vents vs. Ridge Vents:
A ridge vent is a type of static vent, but there are others that appear in multiple locations across the roof, such as gable vents, and provide the same type of passive ventilation that ridge vents do. However, unlike gable vents, ridge vents ensure better consistency when venting hot air, enhancing the home’s overall ventilation efficiency.
Powered Attic Ventilators vs. Ridge Vents:
Powered attic ventilators such as turbine vents require electricity to operate, which adds to your energy bills. On the other hand, ridge vents work entirely through natural air convection, making them a more cost-effective and environmentally friendly option.
How To Install Ridge Vents
Here is a brief overview of the steps to take when installing a ridge vent, however, you should always hire a professional if you’re unsure, or have little experience with roofing work, as they will be able to install it precisely and safely.
Clean and Measure The Roof: Inspect the roof for any damage and measure the length of the ridge to determine the number of vents needed.
Cut Into The Roof: Remove the shingles to slightly expose the roof deck and use a circular saw or utility knife to cut a slot along the ridge, ensuring it’s wide enough to accommodate the vents.
Install the Vent: Position the vent panels over the slot and secure them using roofing nails or screws. Ensure the vents are properly aligned and overlap slightly to prevent gaps.
Secure And Seal: Apply roofing cement along the edges of the vent panels to create a watertight seal. This prevents leaks and ensures the vents are securely fastened.
Final Touches: Install shingle caps over the vent panels if using shingle-over vents. Check for any gaps or loose fittings and make necessary adjustments.
Maintenance Tips for Ridge Vents
Since it’s at the peak of your roof, ridge vents are more vulnerable to damage due to rain and hail, and can wear out faster. This is why you need to take care of it regularly.
Regular Inspection
Conduct regular inspections of your ridge vents to check for signs of damage or wear. Look for loose or missing shingles, gaps, or cracks in the vent panels. Detecting these issues early can prevent costly repairs down the line.
Clean The Vents
Keep the vents clean by removing debris, such as leaves and twigs that may accumulate over time. Use a soft brush or vacuum to clear any blockages that could impede airflow.
Check for Leaks and Damage
Inspect the area around the vents for leaks, particularly after heavy rain or storms. If you notice water stains or dampness, address the issue immediately to prevent further damage.
Hire Professional Maintenance Services
Consider hiring a professional roofing service to conduct thorough inspections and maintenance. They can identify potential problems and perform necessary repairs to ensure your ridge vents continue to function effectively.
