Ventilation System & How It Works.


Is Your Roof Breathing Correctly?

You want to protect your home and everything inside it as a homeowner. Protecting and maintaining the health of your roof is a fantastic place to start. When your home's exterior, particularly your roof, is damaged, it can have serious consequences for both your property and your family. Shield Roofing & Construction wants to assist customers in extending the life of their roof, and the best way to do so is to use effective roof ventilation techniques.


What Is Roofing Ventilation?


Roof ventilation is a system of intake and exhaust vents that circulates air inside a house to make it pleasant. Hot air will get trapped within your home without the in and out passageways included in roof ventilation, generating a variety of problems for your property.


So, what is the most effective approach to increase roof ventilation? When deciding which type of roof vents will give the most effective functionality, consider the climate you live in as well as other property considerations.


Types Of Ventilation Systems


Natural Ventilation - As hot air rises within a home, pressure builds up in the attic. If this high-pressure air is provided a way to exit, it will be replaced by cold, low-pressure air automatically. Homeowners can take use of natural air movement to offer optimum roof ventilation and keep the inside of the home comfortable by installing various types of roof vents. Natural ventilation is also possible through the use of doors, windows, and other openings.


Mechanical Ventilation - A system of mechanical vents may be required for some structures. The steady air flow required by this sort of roofing ventilation necessitates the use of a power source. If the roof design doesn't allow for significant air flow or the home is in a windy area, mechanical rooftop ventilation options are required.


What Are the Benefits of Proper Roofing Ventilation?
Improving the ventilation on your roof will help maintain your roof and the rest of your house in good shape. Warm air will become trapped in your home if you don't follow correct rooftop ventilation suggestions, causing issues that can lead to costly repairs, which we'll detail in the indicators of poor roof ventilation section.

In the Midwest, where we experience both extremes of cold and heat, maintaining your home's roofing ventilation is very vital. Each of the following scenarios should be protected by roofing ventilation options:


  • During the summer, hot air is trapped in your home, making it harder to keep it cool.
  • In the winter, trapped heated air can lead to difficulties like mold, mildew, and ice dams.

Symptoms of Inadequate Roof Ventilation

Ice Dams & Icicles - When there's a lot of snow on the roof and enormous ice dams start to form, it's a sign that there's an issue with the roof ventilation. Ice dams form when the roof warms up, the snow melts, and the running water reaches the edge of the roof, where it freezes. This is a clear sign of insufficient roof ventilation, which can lead to more serious problems. Learn more about how to avoid ice dams on our blog.


Your Air Conditioner Breaks Down - Many people don't associate the health of their air conditioner with the health of their roof, but if you don't have sufficient roof ventilation, your air conditioner may be overworked. Your A/C is working overtime to keep the house cool on hot summer days when all the hot air is trapped within. This puts a strain on your HVAC system, perhaps reducing its longevity. If your air conditioner has failed more than once, you may have ventilation issues.


Home's Hot and Cold Zones - Have you ever noticed a considerable rise in temperature when you walked up the stairs or from room to room? Another symptom of poor roof ventilation is this. Extremely hot or cold spots in the house are another clue that your heating, cooling, and ventilation systems aren't up to the task.

Roof Leaks, Mildew, and Mold If homeowners overlook the warning signals of poor roof ventilation, it can lead to major issues with your home and health in the future. Roof leaks can occur when your roof has been subjected to water damage over time or has been severely damaged by a severe storm.


Unwanted Pests Inside - Roof ventilation difficulties might cause harm to your home's exterior. If your roof, gutters, or siding have been damaged in the past, rodents may be able to gain access. Whether you have microscopic insects that can get in through tiny gaps and openings, or squirrels and rodents that scrape their way into your home, any of these undesirable creatures could indicate a roof problem.


How to Improve Roofing Ventilation

If you’re noticing any of the signs of poor roof ventilation above, it’s time to make some changes to improve the roof ventilation in your home. Roof vent installation is an easy task for roofers when replacing a roof since many roofing ventilation options can be installed under the shingles of the roof or mounted outside the roof.



Home ventilation is all about cool, breezy air coming into your house and stale air being taken out. So, it plays a big part in improving your home’s air quality.
