A well-ventilated attic is a wonderful thing. It makes use of otherwise wasted space. It’s great for cold, mid and hot climates. No matter the architectural design of the house, the approach is basically the same. If executed correctly, roof vents can prevent energy losses, mold, rot and ice dams. A roof vent’s main objectives are to keep air in a home fresh and maintain the roof in good condition. Additionally, it can reduce utility costs. Before doing anything, there are a few things that you should know. Accordingly, the following guide will shine some light on the issue.
What Are Roof Vents?
In essence, roof vents have a rather simple objective: Allowing air to circulate through the attic. However, this serves three important purposes. First, it keeps the interior environment fresh, clean and habitable. Second, it prevents structural damage caused by humidity. Third, it keeps shingles in good condition for a longer time by reducing their temperature. Roof ventilation accomplishes all this by maintaining temperature, reducing humidity and eliminating spores. Technically, an effective vent is one that takes into account space and airflow to move as many cubic meters of air per hour as possible.
One of the most striking aspects of roof vents is that they are effective at any temperature. During hot days, they keep a home’s air pleasantly cool. During cold days, they keep the house dry by eliminating moisture. Although they all work under the same principle, there are many different types of roof vents, each with advantages and disadvantages. Among the most important ones are wind turbines, box vents, power vents, soffit vents, roof ridge vents and off-ridge vents. Something to keep and eye on are solar roof vents, an innovative alternative that runs on renewable, clean solar energy.
Pros and Cons of Roof Vents
1. They Promote Airflow Efficiency
By providing a constant and uniform airflow, roof vents create the perfect indoor environment. In warm climates, this process removes the kind of warm, moist air that is perfect for mold to spawn. In cold climates, aided by properly installed rigid insulation, it helps prevent condensation and moisture damage. Another great thing about this type of vent is that, opposite to popular belief, it does not lower indoor temperature during cold seasons.
2. They Help Save Energy
Roof vents help create a cooler, dryer environment, reducing or eliminating the need to use air conditioning, ceiling fans and other types of electricity-consuming devices.
3. They Help Preserve Roof Shingles
Roof shingles are put through a lot. Among other things, they have to resist direct sunlight, rain, hail, and pollution. Heat is one of the most damaging elements that affect shingles. Without proper attic ventilation, apart from being heated directly by sunlight shingles are also heated from below. This can easily crack them after some time. To avoid that, it’s important to keep the temperature of the attic low by applying proper ventilation.
4. They Function with a Simple and Effective Mechanism
Roof vents take advantage of outside air by letting it into the attic through a very simple mechanism. At the same time, it moves heavy, hot air outside. Externally, it is composed of a roof vent cap, a roof vent boot and roof vent covers. Internally, it features the insulated vent opening that carries the airflow in and out.
5. They Can Be Used in Combination with Other Ventilation Systems
Depending on the particular needs of a home, different types of ventilation may work. Roof ventilation can adapt to most situations, even when used in combination with another ventilation system. For instance, roof venting is extremely effective when used in combination with under-eave venting or soffit.
• They can be difficult to clean: Some people complain about having to clean their roof vents. However, while it is not the easiest job in the world, it’s not that complicated either. The hardest part is cleaning the external parts that are placed on the roof. It needs to be done with care, preferably using proper tools such as roof hooks. Alternatively, there are professional services that provide roof ventilation cleaning services.
What to Expect from Installing Roof Vents
It some cases, it may be hard even to picture how a vent would look like in our home. This may be due to its architectural style, space issues, and many other reasons. However, it’s actually a painless, straightforward process no matter what your roof and attic look like. Despite the dormers, hips, valleys and gables it may have, the roof itself will be barely touched.
It is important to take into account that, in order for this procedure to work, the attic must not be as empty as possible. Cramming it with objects in disuse reduces airflow circulation dynamics, produces extra heat and creates opportunities for mold to be formed. It’s also necessary to make that, even before insulation, the attic is completely air-tight. This is important because the smallest opening could throw off the efficiency or air circulation. If done correctly, the result of installing roof vents will be immediately noticeable. Not only will the attic, but the entire house will have a pleasant and even environment. Furthermore, the roof of the house will get much less hot during the day. As a bonus, the energy bill will decrease.
We can conclude that roof venting is one of the best solutions for controlled indoor temperature. Not only will it improve a house’s overall environment but also it will help preserve its structural integrity. At the same time, it will provide a healthier and cleaner breathing air for its inhabitants. Although having it installed by professionals can be a bit on the expensive side, it’s definitely a worthwhile investment. By doing it, you will make your home stronger, safer, healthier and more comfortable to live in. Without a doubt, roof vents will improve your quality of life.
