Soffit Vents Cost Guide
Soffit vents serve the purpose of directing airflow from the trusses or rafters of the home. They provide positive airflow into attics to prevent humidity buildup behind insulation or mold in the home. In many ways, their function is similar to a vent found in a crawl space in the foundation of the home. The roof is the upper "foundation" of the house and the soffit vent provides aesthetic as well as ventilation throughout the year.
The Costs
-
Minimum Cost: $3 per square foot
-
Maximum Cost: $5 per square foot
Materials
Continuous air vents are installed as a single piece. They come in standard lengths of approximately 8 feet a piece, but have various styles and patterns such as a V-groove or dotted plank. Continuous air vents usually require the use of a J-channel system and drip edge similar to vinyl siding. This provides added stability and the tensile strength needed to flex with the changing seasons.
Round or square soffit vents are used in more complicated roof patterns or with wood soffit and fascia for a custom look. These vents come in a variety of materials such as aluminum and PVC vinyl. Some round or square vents have a wider grill to allow for better airflow in a designated area of the roof. Round vents can also be used in conjunction with continuous soffit vent installation for strategic airflow placement near attics and bonus rooms that are prone to poor temperature control.
Controlling the flow of air and humidity in environments prone to extreme temperature changes or heavy downpours of rain may benefit from the installation of a mini louvred vent. These vents are usually round and can raise or lower the amount of airflow into the eaves of the roof. They come in a variety of trims to match the home's style.
Advantages and Disadvantages of Soffit Vents
Continuous soffit vents have the benefit of the fastest installation on single-story homes or homes with very long and straight roof lines. Unfortunately, continuous vents come in standard sizes and may be expensive for complicated roofs or eaves that are steeply pitched. A round soffit vent creates a custom look and can be installed in any soffit material. Installation is important for these style vents because they can be more susceptible to water infiltration and mold. Round or square mini vents can also be difficult to match to ensure proper airflow. A larger vent may create too much positive airflow in an attic space, which can cause higher energy bills.
In many ways, a mini louvred vent combines superior benefits of all types of soffit vents. It can control the airflow easily during different seasons. The downside to this type of installation is that homeowners will need to be aware of the various changes of humidity and temperature to make them the most effective. Opening the vent too much can allow water to infiltrate while too little ventilation can cause moisture to build up.
