Studor Vent Vs Roof Vent: An In-depth Comparison

Lack of proper venting of the plumbing system may reduce the rate of water flow inside the pipes. Sometimes, due to improper vents or their failure, sewer smell may spread in your house. Nowadays, Studor vents and roof vents are two popular types of venting methods.

Now, let’s know the Studor vent vs roof vent comparison. The first one is cheaper, needs smaller space, and is easier to install and maintain than the latter one. But unlike the former vent type, building codes won’t restrict the use of traditional vents as house venting systems.

In this article, we will enlighten you about some basic differences between these two vent types. After comparing their different factors, you can easily decide which one is better. Thus, keep reading.

An In-detailed Comparison Between The Studor Vent And Roof Vent

We already mentioned some key differences between the Studor vent and the roof vent in the above table. Now, in this section, we will provide you with a detailed comparison between those two:


Normally, the Studor or AAV (air admittance valve) reacts with the negative pressure. Then, the valve will open to allow air into the plumbing system. When the pressure becomes equal, the valve will get closed and will restrict the entry of sewage gas inside the house.

But to release the buildup of positive pressure, you must keep at least one stack vent. Then, these Studor vents are normally one-way and mechanical vents. Firstly, the vent system won’t work properly with all one-way vents. Besides, mechanical vents are pretty susceptive to damage.

Therefore, these AAVs are just a supplement to the traditional stack vents. But if you want to use the former vent, you must keep at least one stack vent for the proper functioning of the entire venting system.

Space Requirements

These AAVs are small in size and do not need large venting pipe arrangements. Contrarily, roof vents will require vent pipes which may take up a lot of space. Also, for 300 sq. feet of roof, you need to install 1 sq. feet of traditional vents.

Ease Of Installation

Studor vents are easier to install than traditional ones. Because, for the former ones, you will need to choose the appropriate location for the vent. Then you need to cut the drainage pipe to attach the vent adapter by solvent welding.

Next, you need to install the vent into the adapter. But in the case of the roof vent, you will need access to the roof and to modify the construction of the roof.


The manufacturers of the Studor claim that their vent won’t need any maintenance after the installation. But as these vents have many mechanical parts, they may malfunction sometimes. Then, you may notice symptoms like bad odor, gurgling noise, etc., from the drainage system.

Normally, a traditional venting system can easily get frozen or clogged with dust. Thus, you need to clean the venting pipes periodically for the effective functioning of the venting system.


According to the claim of Studor manufacturers, their vent functions for up to 500,000 uses or almost 30 years.

But the traditional vent is less durable than the former one. In general, a traditional vent will work properly for almost 10-20 years.

Normally, this vent’s lifespan will depend greatly on its construction materials and maintenance. If you follow the proper maintenance methods, metal roof vents will last longer than plastic ones.


The total cost will depend on the price of the vents and the labor costs for installation. Luckily, the installation of the AAVs is pretty straightforward and you can do it yourself. Thus, you will need to spend only for their prices which range between $15-$60.

In the case of the traditional vents, you may need to pay for the labor costs. In total, you have to spend around $200-$700 for the complete installation of this vent.


All the states don’t allow using the Studor vents in the venting system of houses. Even in some states, the building codes may allow this vent, but they may limit the position and number of vents that you can use.

Thus, before using the AAVs, you always need to check the local venting strategies. Luckily, according to building codes, there are no restrictions regarding using the traditional venting system.

Studor Vent Vs  Roof Vent: Which One Is Better?

  • Which one is better between these two vent types will depend on your personal preferences. Due to the less cost and maintenance, you may think the Studor vent is the better.
  • But remember, due to the mechanical parts, these vents can malfunction often. Fortunately, you don’t have to encounter this issue in the traditional vents as it lacks moving parts.
  • If you are looking for any handy, budget-friendly, and aesthetic, the AAVs type will be a better option for you. Also, when you don’t want to remodel your house design and concern about the aesthetics of the house, pick the AAVs.
  • Sometimes, practical application of the traditional vents won’t be possible in a few cases. Then, you can pick the Studor vents as an alternative to the traditional ones.
  • But, if you choose all the Studor vents for your house, the venting system may fail. Thus, keeping at least one traditional vent is necessary.


In this FAQs section, we will answer a few most familiar questions about The Studor And roof vents.

Q: Are Studor Vents More Reliable In Odor Issues Than Roof Vents?

No. Stack vents are more reliable in this case. Generally, they allow the wafting of odor upward. Contrarily, the odor issue due to the Studor vent failure is quite common.

Q: What Is The Warranty Period For Studor Vent?

Typically, if you use this product according to the guidelines of manufacturers, you will get 10 years. For Studor AAVs, they provide 1 year-lifetime of warranty.

Q: What Are The Alignment Requirements For The Studor Vents?

You must install the vent in an upright position vertically. Importantly, don’t deviate the vent from this position more than 15° if you want an unhampered passway between the pipings and vents.


Your house may have different sections that don’t have roof access; thus, traditional vents won’t be possible there. Yet, you can get Studor vents within a budget-friendly price to install them at those places.

Now, use the Studor vent vs roof vent comparison knowledge to choose the best fit. Normally, the best fit will differ from person to person. You must choose the AAVs if you want a less complex and aesthetic venting way. But choose the traditional one for more reliable and effective venting.
