Continuous soffit vents are one way to satisfy attic air ventilation requirements. Building codes specify that there has to be at least one square foot of ventilation for every 150 square feet of attic floor space. Proper ventilation prevents excessive heat buildup in the attic during summer months, which can shorten the life of roof shingles, and moisture condensation in winter, which could lead to wood rot.

1. Continuous Soffit Vent

To be effective, there must be an equal amount of square footage of air intake and air exhaust. Continuous soffit vents can be used for air intake; however, some people find them unattractive, difficult to install, and some houses may not have an overhang.

2. Vented Drip Edge

Vented drip edge is one alternative. Prefabricated so that there is perforated vent space in the design of the drip edge, this product will provide for air intake along the entire eave and can be combined with a continuous ridge vent, roof louvers or wind turbines for air exhaust.

3. Solar Vent

Another popular choice is a solar-powered gable vent. It works when the sun is shining and provides ventilation when it is most needed during the hottest time of the day. There is no wiring involved, so an electrician is not needed for the installation, and there are no operating costs. The solar panel is installed on the roof.
