Ventilating Your Roof
Have you ever wondered what the vents on your roof are even doing? They actually do quite a bit! Ventilating a residential roof is necessary to maintain the quality of your home and roofing structure. Regular airflow through your home will allow for more consistent temperature regulation and lack of condensation buildup.

Roof Ventilation Explained
There are two types of vents on your home known as exhaust vents and intake vents. The two work together to keep a constant air flow within your home an attic.
- Exhaust vents do what the name suggests. They allow exhaust to escape from your home. These vents are often installed at the intersection of two planes, known as ridges. It can be hard to detect them because they are usually installed under the last layer of shingles, giving your roof a seamless appearance.
- Intake vents are installed to allow cool air into the attic. Doing so will force warm or hot air out of the house through the exhaust vents. These vents can be even harder to detect than ridge or exhaust vents because they are usually installed under the soffit. You may be wondering if you still need vents even if you don’t have an attic. Roof ventilation with no attic is still a necessity. As stated, intake and exhaust vents are needed to prevent build ups of all kinds, which is still true for a home with no attic.
These vents work together to keep the temperature regulated in your home. If you find you are constantly adjusting your thermostats, the problem may not be with the heating or cooling system. It could be with your ventilation.
Roof Ventilation Benefits
If you’re not sold already about ventilating your attic, there are some clear advantages to installing vents in your roof.
- Longevity: Proper and adequate roof ventilation can actually help extend the life of your roof. Here in Texas, we don’t have to worry about damming as much, but it is still an issue. Damming is the result of warm air heating up a roof, melting ice and snow on it. The snow moves down to gutters and freezes in them, causing damage. But when hot air is moved out of the home, it can’t heat the roof up to the point where ice melts.
- Lower Energy Bills: When air can easily flow through your home, you’ll actually find your energy bills lower as the months and years go on. Improper ventilation can cause hot air to build up in the home. When this happens, your cooling system will have to work harder to cool the home, resulting in higher energy bills.
- Temperature Regulation: While vents will help lower your energy bills, they will also help regulate the temperatures in your home. As mentioned, inadequate ventilation means a buildup of hot air that can make your home feel uncomfortable. Add in some vents, and the temperature will be able to regulate itself, making your home feel much more comfortable all year long.
So if you’re wondering about roof ventilation, does it work? The answer would be, yes! Roof ventilation does so many great things for your home that you may not be aware of. Installing, repairing, and maintaining them will make sure your home and roof are in great condition all the time. Rely on Firehouse Roofing, Inc. for any roofing need you may have.
Frequently Asked Questions
- How is roof ventilation calculated?
- Your roofer will need to take into consideration the entire area of your roof as well as the entire soffit area. Everything is multiplied and divided by certain numbers to determine the total number of vents and soffit you’ll need.
- Do attics need to be vented?
- Yes, proper attic ventilation will not only protect your home, but protect your roof as well. Vents are used to allow warm or cool air in and out of the home, helping to regulate temperatures and prevent moisture buildup.
- Can rain get in roof vents?
- No, most vents are designed to prevent water intrusion. That doesn’t mean they can’t experience a build up of condensation during humid seasons, but water will not directly enter the vent during a rainstorm.
- Do roof fans really work?
- The combination of attic vents, soffit vents, and gable vents work in conjunction to work together. It is hard to determine if one works better than the other, but we do know that all the vents on your home are serving a purpose.
- How much roof ventilation do I need?
- For most housing codes, there is a 1/300 rule. It just means that for every 300 square feet of enclosed attic space, there needs to be 1 square foot of ventilation.
