When it comes to maintaining the integrity of your roof, replacing roof vents might not be the first thing that comes to mind. However, roof vents play a crucial role in the ventilation of your home, helping regulate airflow and reduce moisture buildup, which could lead to costly repairs. So, how do you replace roof vents? In this article, we’ll walk you through the process, provide key stats, and explore the often-overlooked details to help Oakville residents keep their roofs in top shape. Plus, we’ll highlight how Everlast Exteriors can assist with all your roofing needs in Oakville.
How to Replace Roof Vents?
Replacing roof vents is an essential part of roof maintenance that helps improve ventilation and prevent moisture buildup, which can lead to mold and damage. Whether you’re replacing damaged vents or upgrading to more efficient ones, the process involves removing the old vents, ensuring proper airflow, and sealing the new ones securely. If you’re unsure about how to replace roof vents, it’s best to consult professionals offering roof replacement or Oakville roofing services. Roof replacement, which involves removing old roofing materials and installing new ones, ensures your home stays protected from the elements while enhancing its value. Roofing services also cover a wide range of tasks, including inspections, repairs, and installation, to ensure your roof stays in top shape. For Oakville residents, trusted Oakville roofing experts can address these needs, offering reliable solutions that withstand the area’s unique climate, from installing new vents to providing full roof replacements.

Why Roof Ventilation Matters?
Before diving into the steps on how to replace roof vents, it’s essential to understand why they’re so important. Proper ventilation in your attic ensures that warm, moist air is expelled, preventing mold growth, wood rot, and ice dams during winter. According to the National Roofing Contractors Association, a roof that is properly ventilated can last up to 30% longer than one that is not.
In Oakville’s climate, with harsh winters and humid summers, the need for efficient roof ventilation is even more critical. Without proper airflow, your attic can become a breeding ground for moisture and even cause your roof’s shingles to deteriorate prematurely. This highlights the importance of replacing your roof vents when necessary.
How to Identify If Roof Vents Need Replacing
You don’t always need to replace roof vents just because they’ve been there for a while. However, there are a few signs that indicate it’s time to replace them:
- Damaged Vents: Check for cracks, holes, or any visible damage to the vents. This can allow water to enter, leading to leaks.
- Improper Airflow: If your attic feels stuffy or if there is visible moisture or mold, the ventilation system may not be functioning properly.
- Roof Age: Vents are often replaced alongside other roof components. If your roof is old, chances are the vents are too.
Tools You’ll Need for Roof Vent Replacement
Before we get into the step-by-step process, make sure you have the right tools on hand:
- Ladder (ensure it’s stable)
- Hammer
- Pry bar
- Roofing nails
- Silicone sealant
- Replacement vents (ensure the correct size for your roof)
- Utility knife
- Roofing shingles (in case you need to replace damaged shingles during the process)
Step-by-Step Guide to Replacing Roof Vents
Replacing roof vents can be a simple process, but safety and precision are key. Here’s how to replace roof vents effectively:
Step 1: Assess the Roof and Gather Supplies
Ensure that the weather is suitable for working on your roof—avoid windy or rainy days. Set up your ladder safely and wear proper footwear to prevent accidents. Also, gather all your tools and replacement vents before climbing onto the roof.
Step 2: Remove Old Roof Vents
To begin, use your pry bar to remove any shingles covering the vent. Once exposed, gently pry off the old vent, being careful not to damage the surrounding shingles. If the vent is nailed down, remove the nails using a hammer or pry bar.
Step 3: Install the New Roof Vent
Before installing the new vent, check that the hole in the roof is the right size. Place the new vent over the hole and align it carefully. Secure the vent by driving nails through the mounting holes.
Step 4: Seal and Reinstall Shingles
Apply a generous amount of silicone sealant around the edges of the vent to ensure it’s waterproof. Once sealed, carefully reattach the shingles around the vent, making sure they are secured with roofing nails. This step is crucial in preventing water from seeping into your attic.
Step 5: Inspect and Test the Ventilation
Once the vent is installed, test the airflow in your attic. Check for any signs of leaks and ensure the vent is functioning properly. If airflow seems insufficient, you might need to consider adding additional vents.
Key Stats About Roof Ventilation You Should Know
- 40% of roof failures are due to poor attic ventilation, which can cause shingles to deteriorate prematurely (National Roofing Contractors Association).
- Homes with poor ventilation can see energy bills rise by up to 30% due to heat buildup in the attic (Department of Energy).
- Proper attic ventilation can extend the lifespan of your roof by up to 30% (Home Ventilating Institute).
Why Oakville Residents Should Consider Professional Help
While replacing roof vents seems like a manageable DIY project, it’s not always as straightforward as it seems.

Common Mistakes to Avoid When Replacing Roof Vents
There are a few common mistakes that homeowners often make when replacing roof vents:
- Using Incorrect Vent Size: The size of the vent should match the size of the hole in your roof. A vent that’s too small won’t provide adequate airflow, while one that’s too large might create an unstable structure.
- Skipping the Sealant: Failing to properly seal the vent could lead to leaks and water damage in your attic.
- Overlooking Shingle Maintenance: If you don’t reinstall the shingles properly, you could expose the vent and surrounding areas to water damage.
- Neglecting Regular Maintenance: Even after replacing your vents, it’s important to check them regularly to ensure they’re functioning correctly.
