Attic ventilation is a critical component of residential roofing systems, ensuring proper air circulation, moisture control, and temperature regulation. CertainTeed, a leading name in roofing and construction materials, offers a comprehensive line of ventilation solutions tailored to meet diverse roof designs and climate conditions. Among these solutions is the CertainTeed Intake Vent, a product designed to facilitate continuous airflow at the roof's edge. This article provides a detailed overview of the CertainTeed Intake Vent, including its features, installation steps, and its role in creating a balanced ventilation system when paired with exhaust vents like ridge vents.
Key Features of the CertainTeed Intake Vent
The CertainTeed Intake Vent is engineered to provide efficient airflow while maintaining weather protection and aesthetic integration with the roof structure. Key features include:
- Continuous Intake Airflow: Positioned at the roof’s edge, the intake vent allows cool air to enter the attic continuously, which is essential for balancing the ventilation system with exhaust vents located near the ridge.
- Internal Baffles and Weather Filter: The intake vent is equipped with internal baffles that help direct airflow while minimizing the risk of rain, snow, or debris entering the attic. An internal weather filter adds an extra layer of protection against dust and insects.
- Drainage System: A built-in drainage system ensures that any water that enters the vent is directed away from the attic space, reducing the risk of water damage.
- Compatibility with Ridge Vents: The intake vent is designed to work in tandem with CertainTeed’s ridge vents, such as the Ridge Vent and Rolled Ridge Vent, to create a balanced ventilation system that enhances overall roof performance.
- Ease of Installation: The intake vent is designed with user-friendly installation features such as pre-drilled nail holes and pre-printed slot guides, ensuring proper alignment and reducing the risk of improper installation.
These features collectively contribute to a ventilation system that not only improves attic airflow but also supports the longevity of the roofing materials by reducing heat buildup and preventing moisture-related damage.
Installation Steps for the CertainTeed Intake Vent
Proper installation is essential for the CertainTeed Intake Vent to function as intended. Based on the documentation provided, the following steps outline the process for installing an intake vent:
1. Gather Your Tools
Before beginning the installation, ensure that all necessary tools are on hand. These typically include:
- Utility knife
- Measuring tape
- Pry bar
- Roofing nails or screws
- Drill
- Roofing sealant
- Circular saw or reciprocating saw
Having all tools ready ensures a smooth and efficient installation process.
2. Plan Vent Placement
Strategic placement is crucial for maximizing the effectiveness of the intake vent. Intake vents should be installed under the eaves of the roof, where cool air can enter the attic. This positioning complements exhaust vents placed near the roof ridge, creating a balanced ventilation system that promotes continuous air circulation.
Careful planning helps prevent issues such as moisture buildup, mold growth, or excessive heat accumulation in the attic.
3. Mark the Installation Area
Once the installation location is determined, use a measuring tape to mark the exact area on the roof where the intake vent will be placed. Double-check the dimensions to ensure they match the size of the vent. Use chalk or a marker to draw visible lines on the roof surface, which will guide the cutting process and ensure accurate placement.
This step is critical for achieving a snug fit and preventing misalignment or gaps that could compromise the vent’s performance.
4. Cut the Opening
Using a circular saw or reciprocating saw, carefully cut along the marked lines. Work slowly and precisely to ensure a clean, accurate cut. This step requires attention to safety, particularly when working at heights. It is recommended to use a secure ladder, non-slip footwear, and a safety harness if necessary.
After cutting, inspect the opening to ensure it aligns with the vent's dimensions and does not interfere with underlying roofing materials such as insulation or wiring.
5. Install the Vent
Once the opening is prepared, place the intake vent into the cutout. Ensure that the vent fits snugly and sits flush against the roof surface. If the vent does not align perfectly, minor adjustments may be necessary. Secure the vent in place using roofing nails or screws, ensuring that it is tightly fastened to prevent shifting or loosening over time.
Proper alignment and secure fastening are essential for maintaining the structural integrity of the roof and ensuring the vent functions as intended.
6. Seal the Vent
To create a watertight seal, apply roofing sealant around the edges of the vent. Use a generous amount to cover any gaps or seams between the vent and the roof surface. A putty knife can be used to smooth the sealant for a clean, even finish. In areas prone to heavy rain or snow, an additional layer of sealant may be beneficial.
Sealing the vent is a critical step in preventing water infiltration, which could lead to leaks, rot, or mold growth in the attic.
7. Test the Ventilation System
After the installation is complete, it is important to test the ventilation system to confirm that it is functioning properly. Enter the attic and observe the airflow. A well-functioning system should show improved air circulation, with hot air exiting through the exhaust vents and cool air entering through the intake vents.
If the airflow is not as expected, inspect the placement and installation of the vents to ensure there are no blockages or misalignments. Proper testing ensures that the ventilation system is effective in maintaining a cool, dry attic environment.
Benefits of a Balanced Ventilation System
The CertainTeed Intake Vent is most effective when used in conjunction with exhaust vents such as ridge vents. A balanced ventilation system offers several benefits:
- Improved Air Circulation: A balanced system ensures that air is continuously moving through the attic, preventing stagnant air and reducing the risk of moisture buildup.
- Moisture Control: Proper ventilation helps regulate humidity levels, reducing the likelihood of mold growth and water damage.
- Temperature Regulation: By allowing hot air to escape and cool air to enter, the system helps maintain a stable attic temperature, which can improve the efficiency of the home’s heating and cooling systems.
- Extended Roof Lifespan: Reduced heat and moisture exposure help prolong the life of roofing materials, including shingles and underlayment.
- Energy Efficiency: A well-ventilated attic can lower cooling costs by reducing the amount of heat that accumulates in the living space below.
These benefits highlight the importance of integrating intake and exhaust vents to create a comprehensive ventilation strategy.
CertainTeed Vent Product Options
CertainTeed offers a range of ventilation products that can be selected based on the specific requirements of a roof and local climate conditions. Key products include:
- Ridge Vents: Available in 9-inch and 12-inch filtered and unfiltered versions, these vents provide exhaust airflow along the entire roofline. They can be capped with shingles for a seamless appearance.
- Rolled Ridge Vent: Offered in 28-foot rolls, this product is available in both filtered and unfiltered options. It includes external baffles to maximize airflow and is compatible with 12-inch ridge shingles.
- Intake Vents: Designed to provide continuous intake airflow at the roof’s edge. These vents are ideal for homes with limited or no overhang and are available with internal baffles, a weather filter, and a drainage system.

Maintenance and Long-Term Performance
To ensure the CertainTeed Intake Vent continues to function effectively over time, regular maintenance is recommended. This includes:
- Visual Inspections: Periodically check the vent for signs of damage, such as cracks, warping, or blockages.
- Cleaning: Remove any debris, leaves, or insects that may have accumulated around the vent to maintain unobstructed airflow.
- Seal Integrity: Inspect the sealant around the vent for signs of wear or cracking. Reapply sealant as needed to maintain a watertight barrier.
- Ventilation Testing: Conduct airflow tests to ensure the system is operating efficiently and to identify any potential issues early.
Maintaining the intake vent and the overall ventilation system helps prevent performance degradation and ensures long-term effectiveness.
