How to Improve Roof Ventilation to Prolong Your Home’s Roof

As a homeowner, you want to protect your home and everything inside it. A great place to start is to protect and maintain the health of your roof. When damage happens to the exterior of your home and especially your roof, it can have major repercussions that affect your home and your family. Our Des Moines roofing company wants to help homeowners prolong the health of their roof, and the best way to do that is by following proper roof ventilation practices.

What is Roofing Ventilation?

Roof ventilation is a system of intake and exhaust vents that provide air circulation to keep the atmosphere inside a home comfortable. Without the in and out passages involved in roof ventilation, hot air will get trapped within your home, causing a variety of problems for your property.

So what’s the best way to improve roof ventilation? The climate you live in and other property factors should be taken into consideration when determining which type of roof vents will provide the most useful functionality.

2 Types of Roofing Ventilation Options

1. Natural Ventilation – Hot air rises within a home and creates pressure in the attic. If this high-pressure air is given an outlet to escape, it will automatically be replaced by cool, low-pressure air. By installing various types of roof vents, homeowners can take advantage of natural air flow to provide proper roof ventilation and keep the inside of the home comfortable. Natural ventilation can also be achieved through doors, windows and other gaps.
2. Mechanical Ventilation – For some structures, it may be necessary to use a system of mechanical vents. This type of roofing ventilation requires a power source to provide constant air flow. Mechanical roofing ventilation options are necessary if the design of the roof doesn’t allow much air flow or the home is in an area without much wind.

Why Is It Important to Have Proper Roofing Ventilation?

Improving your roof ventilation will help keep your roof and the rest of your home in prime condition. If you’re not following proper roofing ventilation tips, warm air will become trapped in your home and cause issues that can lead to costly repairs, which we’ll cover in the signs of poor roof ventilation section.

Maintaining your home’s roofing ventilation is especially important in the Midwest because we experience both extremely cold and hot weather. Roofing ventilation options should protect your home from each of these scenarios:

• Hot air trapped in your home during the summer, making it difficult to keep your home cool
• Trapped hot air causing issues like mold, mildew or ice dams in the winter

Signs of Poor Roof Ventilation

Icicles & Ice Dams – When there’s snow piled up on the roof and you start to notice large ice dams forming along the roof, that means there’s a problem with the roof ventilation. Ice dams form when the roof is heating up, the snow is melting and then the running water is freezing once it reaches the edge of the roof. This is a major indicator of poor roof ventilation and can cause more serious issues. Learn more in our blog about how to avoid ice dams.

Your Air Conditioner Breaks Down – Many people don’t correlate the condition of their A/C with the health of their roof, but if you don’t have the proper roof ventilation in place, you could be overworking your air conditioner. On hot summer days when all the hot air is trapped indoors, your A/C is working in overdrive to keep the house cool. This puts stress on your HVAC system, and can shorten the lifespan of the unit. If your A/C has broken down more than once, there’s a good chance you have ventilation problems.

Hot or Cold Areas in The Home – Have you ever felt a noticeable increase in temperature when you walk up the stairs or from room to room? This is another sign of poor roof ventilation. Extremely hot or cold areas in the home is another sign that your heating, cooling and ventilation systems are not keeping up with the demand.

Roof Leaks, Mold & Mildew If homeowners ignore the warning signs of poor roof ventilation, it can lead to serious problems later on for your home and your health. When your roof is exposed to water damage over time, or suffered major destruction from a bad storm, this can cause roof leaks. If these are not treated right away, the excess water in the home could create additional problems like mold, mildew and more.

Unwanted Pests Found Inside – Some roof ventilation issues lead to damage to the exterior of your home. If your roof, gutters or siding have been damaged in the past, it could allow critters to find a way inside. Whether you have tiny insects that can creep in through tiny cracks and crevices, or squirrels and rodents that can scratch their way indoors, any of these unwanted pests could be an indicator that there’s an issue with your roof.

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. There are many different types of roof vents, so we’ll discuss your roofing ventilation options in more detail below.

2 Types of Roofing Ventilation Systems

Exhaust Vents: Allow Hot Air to Escape The Home

Intake Vents: Allow Cool Air to Enter The Attic

Benefits of Proper Roof Ventilation

Save Energy Costs – Poor ventilation can lead to rising temperatures in the attic, which spill over to the rest of the home. This leads to high electricity bills, inconsistent heating and cooling within the home and puts more burden on your HVAC units.

Keep Your Home Healthier & More Comfortable – Improper roof ventilation can lead to mold and mildew build up, which can not only damage your roof but pose health risks to your family. Additionally, you won’t have to deal with temperature changes within the home when you follow proper roof ventilation tips.

Prolong The Life of Your Roof – Poor roof ventilation can cause damage and lead to a shorter lifespan for your roof. The top damages include:

• Shingles get very hot and prematurely age when poor roof ventilation keeps the attic too warm.
• Ice dams are a sign of poor roof ventilation, and they cause damage to shingles and eaves. If left untreated, they can even cause roof leaks.
• Moisture buildup from various roof ventilation problems can lead to swelling and rot, which can result in nails not holding and reduced roof capacity
