Your roof is an important part of your home, so you must take the proper steps to make it last longer. However, there are a number of things that affect how often you should fix your roof. As an example, asphalt roofs last between 15 and 20 years. The place where you live is another important thing to think about.
Your roof will last less long if you live in an area with strong winds and ultraviolet (UV) rays. Ensuring it has enough airflow is an excellent way to make your roof last longer. This raises a good point: what is roof ventilation, and what roof ventilation types should you consider for your next home improvement project?
Reason Why Roof Ventilation is Important
Warm air rises, and if your roof doesn’t have enough airflow, it will stay in your attic and cause problems. This issue demands good roof ventilation. Insufficient ventilation can cause warm, moist air to freeze in the attic in winter. In contrast, summer humidity and stagnant air can promote rot and mold. To avoid these issues, install proper roof ventilation types to ventilate your attic and keep your home healthy.
Having enough ventilation in the roof lets air flow through the attic, getting rid of hot and wet air and stopping the problems that come with too much moisture buildup. Cool air should be able to get into the attic near the eaves and leave around the peak. On the last day, you want the temperature and humidity in your attic to be the same as they are outside.
What Type of Roof Venting is Best?
There are a lot of different sizes, styles, and roof ventilation types. You may know the difference between ridge vents and gable vents, but it’s also important to know the difference between louvered vents, turbine vents, power vents, and roofing exhaust vents. Depending on the style of your roof and how much airflow you need, each has its own perks.
Ridge vents are great because they run along the highest part of your roof and let hot air out of your attic. Most ridge roof vent cap is simple to set up, making them good for homeowners who want to put something outside without a lot of work. Also, they go all the way across your roof line. Ridge vents are made to withstand heavy rain, snow, and garbage that build up during bad weather.
Roof turbines use wind to move air out of your attic, which lowers the chance of mold growth. The inner blades won’t spin if there is no wind. Power is unnecessary to run them because the wind does the work. Since turbine vents are smaller than box vents, you’ll need to put in more than one to get good attic airflow.
Drip Edge Vents
The roofing material under your roof’s shingles is part of drip edge vents. Their job is to help water move into the gutters. A malleable metal was used to make the vent. A malleable metal can change shape when it is compressed. The shape of a drip edge vent may have holes on the sides.
There are several forms of cupola vents, such as square, round, and octagonal. The main reason for these holes is to let more light in through the bottom. Louvers or windows are the two most common ways cupolas allow air to flow through them.
Box vents are square shapes that are spread out on your roof. Like off-ridge vents, box vents work best on roofs with many different parts. Most box ports are 18 inches by 18 inches. Box vents let hot air and moisture escape from inside your home when put across your roof’s surface.
Like the other vents on this list, attic vents help move heat away. They also have a small screen between the louvers that keeps bugs from getting in through the vents. Dormer vents are a good choice if you want something stylish and nice to look at because they can match the color of your roof.
Soffit vents are devices that are put under the eaves of your roof, which is the part that goes past the siding on the outside. These vents let air flow through your attic and around it. There are soffit devices that go all the way along the edges of the roof and devices that are spread out.
Felt Lap Vent
Even though they’re rare, felt lap vents can be useful if you live in a house that doesn’t have good airflow or that tends to get condensation. Most of the time, these vents are put on roofs with waterproofing layers. They can help existing roof areas breathe better.
Dry Ridge Vent
Dry ridge vents are helpful because they are easy to assemble and don’t require many materials. These holes were originally made to hold ridge tiles in place, but they also let air flow in without being seen. By using these vents, homeowners can keep bad germs from growing. The vents won’t fall off in strong winds, which is the best thing about them.
When the wind hits the roof, over-fascia vents make it easier for air to get in. Shields go over the top of the vent in this case. If your roof doesn’t have enough room for soffit vents, you can use over-fascia vents to let air into your roof and attic. These vents have holes in the edges that allow air to come in from under the roof.
Hard-Wired Powered Attic Vents
Hard-wired vents are round parts that use electric fans to pull hot air under the roof deck. They are also called powered attic ventilators. These vents also use electricity to keep the temperature in your attic steady while letting hot air out. One bad thing about using them is that they might move unwanted air around instead of removing it.
Solar-powered vents are great because they can get rid of almost all of the electricity costs that come from vents that don’t work well. Solar-powered systems get their power from the sun, as the name suggests. They’re not the best choice if you live somewhere that only gets a little sun. Because they need sunlight, it might be hard to keep your roof well-ventilated.
What Is The Ideal Roof Ventilation?
A well-ventilated roof pitch is essential for building durability and efficiency. Moisture can cause rotting, mold, and other structural issues in the attic, so enough airflow is necessary. Effective roof ventilation types help air flow, maintain a healthy environment, and avoid damage. Allowing air to move through the roof reduces moisture issues and regulates the building’s temperature, making it a suitable living or working place.
A roof should be able to let enough airflow through it so that it lasts as long as possible and doesn’t need expensive repairs in the future. How much airflow a roof needs will depend on its size, slope, and the type of attic or crawl space it has.
You should allow one square foot of airflow through a roof for every 150 square feet of attic or crawl room. The 1/150 airflow rule is the name for it.
The 1/150 ventilation rule is a rule that everyone agrees on when it comes to roof ventilation. This rule says that for every 150 square feet of attic or crawl room, a roof needs to have at least one square foot of ventilation. For a 2,000-square-foot attic, there needs to be at least 13.3 square feet of airflow. It’s important to remember that this is just the bare minimum; you may need more ventilation based on other factors.
