The ventilation system is one of the most important parts of your roof. Ventilation is essential for your roof’s longevity and the safety and health of your family. You can save money on your energy bills.
Why ventilation is important
Proper ventilation prevents heat from building up in your attic. This can lead to premature deterioration or damage to your roofing materials. Good ventilation is essential for prolonging the life of your roof as well as keeping your home more energy efficient.
Your roof can also be ventilated to help keep your home cool in summer and warm in winter. You can reduce your energy costs by circulating the air in your attic.
Styles of Roof Ventilation
There are three types of roof ventilation.
Passive Roof Ventilation
Passive roof ventilation uses natural convection to ventilate attic spaces. This type of ventilation is often achieved by vents located along the ridge or in the area below the eaves.
Wind-Powered Ventilation
Wind-powered vents use the energy of wind to turn a turbine that suckers air from the attic. These turbines, affectionately known as ” Whirlybirds”, are installed on top of circular fans.
Because they are flexible, they can be used in place of ridge vents. They also prevent mold, mildew, and rot from building up in the attic. Because they don’t require electricity to operate, there is no ongoing cost for energy like with electric-powered vents.
Roof Ventilation Powered by Electricity
To move moisture and hot air out of an attic, electric-powered vents use solar or electric fans. The operation of some electric vents can be controlled by thermostats or humidity sensors.
For maximum efficiency, the electric-powered vents must be placed at the roof’s peak. They should not be used in combination with any other ventilation systems.
Types of Roof Ventilation
There are many ways to ventilate your roof. The best way depends on the type of roof you have and the material used for roofing. Below are some of the most popular methods for roof ventilation:
Ridge Vents
Ridge vents are located along the roof’s ridgeline and distribute heat evenly throughout the roof’s horizontal roof ridge. These vents can be integrated into the roofline to improve the building’s appearance. A ridge vent can be compared to an open book sitting on top of a roof’s edge.
Ridge vents are not dependent on wind, so they offer excellent performance throughout the year. Ridge vents can reduce roof aging and prolong the life of your roof.
Soffit Vents
Soffit vents can be used to improve your roof ventilation and attic ventilation. They are located under your roof’s eaves and help remove hot air and moisture. Flat roof homes have soffit vents which are one of the most efficient methods of venting hot air and moisture.
Gable Vents
Gable vents are a popular method of venting an attic. These vents are placed in your gables or end walls. Gable vents are designed to allow airflow out of your attic and prevent moisture from entering. However, roofing contractors may advise against installing them in areas where there is heavy rainfall.
Gable vents have one drawback: they require strong winds to work effectively. This makes them unsuitable in areas with poor air circulation or where the wind blows on the home’s gable ends.
Gable vents are available in many sizes and shapes to fit the design of your home.
Roof Turbines
Roof turbines can be a great way to increase roof ventilation and attic ventilation. These turbines are simple to install and can be used on any roof type, even flat roofs. Roof turbines spin in the wind to help ventilate and freshen the attic. Roof turbines are a great option for improving ventilation in areas with high winds.
Power Vents
The power vents can remove hot air and moisture from your attic. This can prolong the life expectancy of your roof. There are two types: electric-powered power vents and solar-powered power vents. The sun powers solar-powered power vents, which are totally free to use. While they require a smaller amount of electricity to operate, electric-powered power vents are more reliable and powerful than solar-powered ones.
Box Vents
Box vents are small additions that are installed on top of roof holes. Natural winds and convection are the main sources of power for box vents. This is a circular motion that results from the exchange of warm air which changes temperatures. They are not used in single units. The square footage of an attic determines how many boxes vents can be added to a roof.
Box vents have a drawback: they require many holes in the roof. This can increase the cost of a roofing job and adds to the labor involved.
Cupola Vents
Cupola vents were invented by farmers in the 1800s to ventilate their barns, which had become more well-constructed and airtight. An American farmer created the first cupola vent. It proved to be an ideal solution for dispersing heated air and moisture.
Cupolas can cool interiors with minimal air conditioning. A cupola, when glass is used in a design, can be used as an architectural feature, cooling mechanism, and skylight.
The type of roof that you have will determine the best type of roof ventilation system. Ridge vents might not be an option if your roof is flat. Gable vents and soffit vents are possible options for venting your roof.
Flat Roof Venting Types
The majority of the above-mentioned venting methods will work with a standard pitched residential roof. Flat roofs are different, and you need to know the best roof ventilation methods if your roof is not sloped.
Ventilating a flat roof requires equal air intake and exhaust. Cross ventilation allows hot, moist air to be replaced by fresher air.
These are some additional vent types for flat roofs.
Pop Vent
These mechanical vents create airflow by using a fan. These vents are popular on flat-roof homes because they can draw in fresh air from the outside and remove hot air from the inside.
Aura Vent
Aura gravity roof ventilations are nonmechanical vents that remove heat from hot temperatures and moisture from cold. A mechanical aura vent has a fan that draws in the fresh air and forces air out.
Boot Vent
A pipe that is inserted through the roof to create a boot vent is all it takes. Named after the rubber boot, which is used to stop leaking.
Breather Vents
Breather vents can be used in multiples to allow air to flow freely between roof sections. A breather vent below opens or closes depending upon the moisture level. Because they operate under pressure, breather vents can be very efficient.
Ventilating finished attics
Attic space can be used as a bedroom, office, or living area in some homes. The attic must be heated and cooled as the rest of your home. This will determine what type of roof venting can be used. Gable vents in walls are not an option because they allow air to escape.
Ventilating attics that are not finished is essential as the roof’s underside would be exposed to extreme temperatures.
In such cases, rafter venting is commonly used. These vents are placed in the space between the rafters to create small gaps that allow air to flow from the soffit vents up to the roof’s peak. This provides good ventilation and preserves the finished appearance of the attic.
How to improve roof ventilation and attic ventilation
You may be curious about what you can do for your roof and attic to maximize their efficiency, given the many benefits of roof ventilation. There are several things you can do to improve ventilation in your home.
- Check that there aren’t any obstructions to your vents. You should also ensure that there aren’t any trees or shrubs near your vents.
- If your home has soffit vents, make sure insulation isn’t blocking them.
- If you need more vents, you can always add them. If you have a flat roof you can place vents around the perimeter.
- Insulate your attic. This will prevent heat buildup in your attic, and allow cool air to flow more freely.
It is a good idea to have a professional assess your home and determine if it is adequately ventilated. They can assess your home and recommend the best method of ventilation to protect your roof. They will also conduct a roof inspection to find any problems and suggest solutions before they become more serious.
You can increase the lifespan of your roof by improving the ventilation. This will also help you save money on your energy bills. It is essential to maintain a safe and healthy home for your family.
