Choosing the best type of attic ventilation for your home depends on various factors, such as the size of your attic, the kind of roof you have, the climate in your area, and your personal preferences. 

Here are some of the main benefits of proper attic ventilation:

  1. Reducing Heat Buildup: During hot summer months, the temperature in your attic can reach incredibly high levels, making it difficult for your air conditioning system to keep your home cool. Attic ventilation helps to reduce heat buildup, which can lower the temperature in your attic and make it easier for your air conditioning system to work efficiently. This can result in lower energy bills and improved comfort in your home.
  2. Preventing Moisture Buildup: Moisture buildup in your attic can cause mold and mildew growth, leading to health problems for you and your family and damage to your home. Proper attic ventilation helps to remove excess moisture and prevent these issues from occurring.
  3. Extending the Life of Your Roof: High temperatures and excess moisture in your attic can cause damage to your roof, leading to costly repairs or replacement. Attic ventilation helps to reduce the temperature and moisture levels in your attic, which can help to extend the life of your roof.
  4. Improving Air Quality: Stagnant air in your attic can become filled with dust, allergens, and other pollutants, which can circulate throughout your home and impact your indoor air quality. Attic ventilation helps to remove these pollutants, improving the overall air quality in your home.
  5. Meeting Building Codes: Many building codes require proper attic ventilation to be installed in residential properties, so installing attic ventilation can ensure that your home is up to code.

Attic ventilation is important for maintaining your home’s overall health and comfort. Proper attic ventilation can also help you save money on your energy bills by reducing the workload on your air conditioning system.

Here are some general guidelines to help you determine the best type of attic ventilation for your home:

Ridge Attic Vents 

Ridge vents are one of the most common types of attic ventilation systems. If your roof has a ridge, then installing ridge vents is a great option. Ridge vents run along the entire ridge of your roof and work by allowing hot air to escape through the top of your roof while fresh air enters through the soffit vents, creating a natural flow of air. This type of ventilation is very effective and energy-efficient, and it does not require electricity to operate. 

This type of ventilation system effectively removes hot air from your attic, prevents moisture buildup, and improves air circulation.

Gable Attic Vents

Gable vents are installed on the gable end of your roof and allow air to flow in and out of your attic. They work best when paired with soffit vents, which allow fresh air to enter the attic space. This type of ventilation system is ideal for homes with a steep-pitched roof or a limited ridge line.

Gable vents are particularly useful for homes with steep-pitched roofs or those with a limited ridge line. Gable vents are relatively easy to install and cost-effective.

Soffit Attic Vents

Soffit vents are easy to install and are a cost-effective way to improve your attic’s ventilation. Soffit vents are installed under the eaves of your roof and are designed to allow cool air to enter the attic while hot air exits through the roof vents. Soffit vents work best when used with other roof ventilation systems like ridge vents or gable vents.

Soffit vents are an effective way to prevent moisture buildup and improve air circulation in your home.

Turbine Attic Vents

Turbine vents are a type of attic ventilation system that uses wind to create a flow of air through your attic. They are installed on your roof and have a spinning turbine that draws hot air from your attic. Turbine vents are an effective way to remove hot air from your attic space, but they can be noisy and may require maintenance to keep them working properly.

Power Attic Vents

Power vents are electrically powered fans that are installed on your roof to remove hot air from your attic. They are effective at removing hot air quickly and can be controlled by a thermostat or humidistat. However, they require electricity to operate and can be noisy.

Loose-Fill Fiberglass Insulation vs. Cellulose

Water Vapor Sorption Mold: Fiberglass insulation is non-absorbent and will not hold water which will eliminate any loss in insulation value. Cellulose is absorbent and can take up to 2 months to dry out in order to give you the best insulation value. This means that the insulation value of cellulose fluctuates while fiberglass stays consistent.

Resistance to Corrosion: Fiberglass insulation is not corrosive and contains no chemicals than can corrode pipes or wires. Cellulose contains chemicals that are routinely applied as a fire retardant which can cause corrosion of pipes, wires, and fasteners. 

Fire Safety: Fiberglass insulation is made of sand and other inorganic materials that are naturally non-combustible, making fiberglass an acceptable fire stop in residential buildings. Cellulose insulation is made of naturally combustible materials and is recognized as a fire hazard by the Consumer Product Safety Council.  

Performance: Fiberglass insulation has an R-value of R-15, while cellulose has a lower insulation value at just R-13. Fiberglass insulation is also easier to install and lighter in material, saving you on the cost of labor and transportation. 

What is the average price of an attic ventilation installation?

The cost of installing attic ventilation in your home can vary depending on several factors, such as the type of ventilation system you choose, the size of your attic, and the complexity of the installation. Here is a rough estimate of the cost of different types of attic ventilation systems:

  1. Ridge Vents: The cost of installing ridge vents in your home can range from $400 to $1,000, depending on the size of your roof and the complexity of the installation.
  2. Soffit Vents: Installing soffit vents in your home can cost between $2 to $10 per linear foot. The cost will depend on the type of material used, the size of the vents, and the complexity of the installation.
  3. Gable Vents: The cost of installing gable vents in your home can range from $50 to $300 per vent, depending on the vent size and the installation’s complexity.
  4. Solar Attic Fans: Installing a solar attic fan in your home can cost between $300 to $800, depending on your attic’s size and the installation’s complexity.
  5. Whole House Fans: The cost of installing a whole house fan in your home can range from $1,000 to $2,500, depending on your home’s size and the installation’s complexity.
