Ventilation is important for all parts of your house, and the roof is no exception. The term refers to a system which allows air to flow through the intake and exhaust.
Roof ventilation is not a new process by any means. The early- to mid-20th century saw the development of this concept. Big organizations like the Forest Products Laboratory and even the American Society of Heating, Refrigerating & Air-Conditioning Engineers realized that poor roof ventilation systems could cause condensation problems in a building.

Installing a roof ventilation system can help you in the following ways:
- Your roof will become much more durable once it is vented. Ice damming can often make the roofing materials weak and ineffective. As a result, the whole roof system will be prone to damage. Proper ventilation will prevent this from happening.
- Vented roofs let out the heat from inside your house which gives a cooling effect. As a result, you will use the air conditioner less and pay a lower electric bill at the end of the month.
- If you find that indoor temperature extremes plague your life, then vented roofs are the perfect solution.
There are a number of excellent roof vents available in the market. If you are confused about which one to buy, then you have come to the right place because I have prepared a thoroughly researched guide for you.

How to Choose the Best Roof Vents?
Buying the best roof vent is not an easy job by any means because there are so many things that you need to take into consideration. If you do not want to regret your purchase later, you must take into account certain factors which will determine if a particular roof vent is perfect for you.
1. The shape and size of the roof:
Undoubtedly one of the most important determinants, the structure of the roof often decides whether a vent will be suitable for you or not. You must measure the area of your roof before you start looking for vents, so you know exactly how many you will need and where you want to place them.
Different roofs have different requirements because roofers use a variety of materials and techniques to build roofs. If you do not know this detail from beforehand, you will face problems in determining the size of the vents that you need for your home.
Installing roof vents is not something you want to do every weekend because the previous one fell apart. When you are installing a ventilation system, you must be sure that it will last you for a while so that you do not have to spend money behind repairing it or buying a new one within a few months. Since they are to be installed outside the house, roof vents should be weatherproof.
No amount of heat or cold should be able to damage the functioning of the vent. Make sure that your vent comes with the guarantee of withstanding all weathers.
The material with which the roof vent is made can actually make a huge difference in how it functions. There are some which are made of metal and are hence sturdier, while there some which are made of materials like polypropylene which prevents them from getting cracks during winter. This is a personal choice that you have to make according to your preferences.
4. Installation process:
You simply want to install a roof vent because you do not want your house to have a moderate temperature and you do not fancy your roof collapsing because of damage caused by weather elements. Ideally, it should not be a lot of work. Most roof vents come with detailed installation manuals that tell you exactly what you have to do. Vents should be such that they can be even set up by people who have limited exposure to tools.
5. Secondary features:
Roof vents can come with a lot of additional features that will make your life even easier than before. If you are paying the full price for a vent, then you can also expect these features to be present. New roof vents almost always come with screens which prevent unwanted entry of birds and insects into your house. They also have built-in back-draft dampers, which prevent the cold wind from flowing right back into your house.
You might be wondering why you should factor in the appearance of roof vents. There is no strict regulation which states that products cannot combine functionality with attractiveness. You should look for a roof vent that will fit into the design of your house as effortlessly as possible.
Any kind of work associated with roofing is hardly very cheap. You have to invest a fair amount of money in order to get the best results. Once it is done, you will not regret it.
Best Roof Vents Buyer’s Guide:
1. Can intake and exhaust vents be used together?
The truth is you should use both intake and exhaust vents in your roof vent system so they can work in tandem and transfer the air. You must examine the area of your roof and your house to figure out how many of each you will require to make a superior ventilation system. Since you will be spending money, get the best.
2. What do intake vents do?
The purpose of intake vents is to transfer the air from outdoors into your house. Soffit vents and Eave vents are examples of intake vents that you might need in your house or attic. They are installed along the edge of the roof. It is important you make sure no insulation or any other material is blocking the vent, or it will not work properly.
3. What is the purpose of exhaust vents?
Exhaust vents, unlike intake vents, are installed at the topmost point of the roof. They are meant to let the air from indoors travel outdoors, so there is continuous air flow. The trapped hot air goes out from the attics through the ventilation space into nature. They help eliminate moisture from your attics which in turn can keep your roofs stable for longer.
4. Are there different kinds of exhaust vents?
Yes. Depending on the type of roof your house has, you may choose any of the following types of exhaust vents:
Ridge Vent: If your roof has a lot of ridges, you can use this form of ventilation.
Gable Vent: Meant for the gables of the roof.
Power Vent: Powered by electricity, this requires high maintenance.
Wind Turbine: Versatile and can be installed on any roof.
5. Does roof ventilation work throughout the year?
Ideally, all roof vents should be functioning all year round. Otherwise, it defeated the purpose of continuous air flow in and out of the house. No matter how hot or cold it is outside, the vents should work without getting damaged if you want a stable and moderate temperature inside the house. Check for weatherproof options that will not let you down.
6. Why are roof vents made of different materials?
As mentioned before, there are different kinds of roof vents available in the market. It is only fair that manufacturers use materials more suitable for the design of their vents than follow one standard pattern. You can choose between study galvanized metal or artificial components depending on what your priorities are. The former is stronger, but it can also get corroded more easily.
7. How does roof vents protect roofs from ice?
Sometimes, icicles can freeze along roofs and gutters causing a phenomenon called ice damming. You do not understand how damaging it can be until much later. The heat within the attic causes the snow to melt and then it again refreezes beneath your roofing. With proper ventilation, the warm air will be transported before it can melt the ice and cause any kind of jamming.
8. Are roof vents useful during summers?
As the temperature rises outside, you cannot figure out how to cool down the interior of the house. Why does that happen? The rise in outside temperature also increases the temperature of the roof which in turn heats up attic. Heat cannot escape through unventilated attics, and so it becomes oppressive. Having a vented roof will drive away the warm air and greet you with cooler air.
9. Are roof vents easy to install?
This largely depends on the kind of roof vent you are planning to purchase. If you are planning to make an entire system of vents, then it is best that you hire professional help because you can get hurt in the process. On the other hand, if you have some experience with mechanics and tools, you will be able to install roof vents on your own.
10. Do all roof vents cost the same?
No. Different price ranges are catering to different sections of the public in the roof vent market. Moreover, there are a variety of sizes available because not everyone has the same kind of roof. This leads to different pricing even on the same model when you choose a bigger size. The prices of roof vents also go up when manufacturers add extra features to the vents.
I mentioned five excellent roof vents in this article, but my favorite has to be the Lippert Components 389381 White Roof Vent because of the patented 360 Siphon design it has adopted. It shares almost all the other features with the rest of the products, but this makes it unique. If you want to live in an odor-less, oxygen-rich environment, then you cannot go wrong with this roof vent.
Moreover, you do not even have to spend a lot of your time and effort into making it functional. The low maintenance and easy installation can prove to be boons. The Broan-NuTone 634M Roof Cap Black Up to 6" Round Duct is a close second. Take your pick!
