Importance of Roof Ventilation

Adequate air circulation is essential to preserve the integrity of your roof. Ventilation is beneficial for roofs in many ways. It enhances the life and quality of the roof, brings down energy expenses, and keeps the interior of your home comfortable. Let’s take a closer look at the importance of proper roof ventilation.


Why is Adequate Roof Ventilation Important?


Adequate roof ventilation offers several advantages to homeowners. Here are some benefits:


It Enhances the Life and Quality of Your Roofing Materials


One of the biggest problems residential homeowners see with improper ventilation is ice dams forming in colder months. Ice dams form when heat from the inside of your home meets the cool air outside and creates a buildup of ice around the edges of your roof. This prevents water from properly draining from your roof when it rains. As ice dams melt and refreeze, they can create significant damage underneath your shingles that moves into your home’s interior.


In hotter months, improper ventilation can lead to buckling or breaking your roof shingles when hot air forces itself out of your roof as it tries to escape from your attic. Proper ventilation can prevent these issues from occurring because it keeps the air inside your home circulating properly to minimize roof damage and extend the life of your investment.

Proper Roof Ventilation Decreases Energy Expenses


During hot weather, a properly ventilated roof keeps the inside of your attic cool. When not adequately vented, attic temperatures can reach over 150 degrees! This increases your energy usage as your air conditioner needs to work harder to keep your home at a comfortable temperature. Not only does this lead to high energy bills, but it also increases the workload on your appliances. With proper ventilation, you can extend the life of your appliances and lower your energy bills.


It Prevents Blistering and Damaging of Walls


As attic temperatures rise, the heat that accumulates needs a place to escape. If it doesn’t force its way out your roof, it can move through your walls, causing the paint to blister and damaging the interior of your home.


Additionally, condensation can form, bringing moisture into your home: this damages wallpaper, paint, your roof, and even your belongings.


The Purpose of Good Ventilation


  • A well-ventilated attic provides good insulation, enabling you to live comfortably without being affected by extreme climate changes outside. You can enjoy the comfort of your home and afford minimal energy expenses.
  • It helps to maintain a subtle and moderate temperature by enabling adequate airflow from inside to outside while limiting the energy cost and expenses each month during any kind of weather.
  • The vents installed for a well-insulated attic during rising temperatures are small enough to prevent the escape of dirt, debris, and small animals inside. Vents are large enough to allow air insulation.
  • Attic fans are purposely installed during summers, removing hot air from inside your home and allowing the entrance of cool air to reduce air conditioner usage.
