Like it or not, you are still paying for that space in utility bills, and you might even be missing out on usable floor space. You want to get organized to come up with a plan. One decision you will need to make is whether you want a vented vs unvented attic.

Traditionally, attics were vented and insulated with cellulose or fiberglass. For the ventilation system to be effective, there needs to be a balance of intake and exhaust vents. The intake vents are positioned in the soffits or eaves, and the exhaust is near the top of the roof line. Usually, this is a static system, relying on the natural movement of warm air rising. However, some buildings incorporate mechanical assists such as power vents.
Advantages of a Vented Attic
- Lowering attic temperature
- Reducing air conditioning costs
- Removing excess moisture or condensation
- Reducing the possibility of mold and mildew
- Minimizing the potential for wood rot
- Optimizing the life of the roofing
- Many single warranties and local building codes require attic ventilation
Disadvantages of a Vented Attic
- Possible extreme temperature changes in the attic depending on outside air
- Regular monitoring of vents to ensure they are working properly
- Attic space is not conditioned, which limits use; e.g., no HVAC equipment
A growing awareness of the benefits of energy efficiency has popularized unvented attics. Energy audits always include an assessment of attic construction and insulation. This has led to a more comprehensive look at attic space and its potential. Many homeowners want to find ways to use the square footage more effectively.
Advantages of an Unvented Attic
- Sealed house envelope, making it more energy efficient
- Reduced energy bills, e.g. warmer in winter, cooler in summer, reducing furnace and HVAC load
- Moisture resistance
- Protection for any mechanical systems in the space
- Prevention of ice dams that can ruin the roof
- Additional options for using attic space, e.g. more living area, safe storage
Disadvantages of an Unvented Attic
- The increased expense to insulate properly
- Possible voiding of shingles warranty
- Possible non-compliance with building codes (although this is changing across the country)
Considerations for Making a Decision
In order to make the best decision possible about upgrading your attic, you will want more information in certain areas. Some of this has to come from professionals, and then there are more personal factors to consider.
- Assessment of the attic as it is: You need to know what you are actually dealing with. This means bringing in an experienced local building company for an assessment of your attic. Most reputable companies will do this for free. A professional representative will come on-site, look the attic construction and layout, any vents, insulation, and HVAC systems, answer your questions, recommend options and prepare a quote for the work to be done.
- Typical options: The two major options are usually whether or not to vent and what kind of insulation. Traditionally, vented attics have been insulated with cellulose or fiberglass. However, even if you are maintaining the vents, a change to spray foam insulation might be economically practical and more effective. In an unvented attic, spray form insulation provides a good air seal to make the entire home more energy efficient. This insulation also protects HVAC and duct systems in the attic.
- Motivation: Another consideration for making a decision about an attic update is your motivation for doing it. There are typically three main reasons you are calling in the professionals.

Typical Reasons For An Attic Update
Below we discuss some of the typical reasons homeowners opt to upgrade their attic space.
First, you want energy efficiency. This has become a common phrase to apply to any building or renovation project in the last several years. You might even have taken advantage of government-subsidized energy audits or upgrades to your home.
Energy efficiency has an impact on:
- Costs of utilities: Whether it is an upgrade to your attic vents and/or insulation, the monthly bills for electricity or heating fuel will certainly decrease.
- Environment: Any savings on energy consumption mean a reduction on your carbon footprint.
Secondly, you want to safeguard your family’s health. Even if you do not want to do away with all attic vents, just upgrading them and installing appropriate insulation greatly decreases the possibility of mold and mildew. In turn, this maintains good air quality throughout the home, decreasing health hazards.
A third motivator is usually the household’s comfort. Good insulation and seals prevent drafts and allow the HVAC systems to work to their optimal capacity. This means everyone is comfortable in a consistently conditioned environment.
