Plano Roofing: Article About Roof Vents
Without sufficient attic ventilation, homeowners can expect to pay for higher power bills on a monthly basis. Air that is trapped between the ceiling and roof deck can reach triple-digit temperatures in the summer heat. Subsequently, the cooler air from the building's interior gets pulled into the upper level requiring the HVAC unit to work harder. On the other hand, a structure with a well-designed roof ventilation system loses very little of its conditioned air. Low pressure brings outside air in through soffit vents and then guides it along the bottom of the sheathing until it reaches the ridge. The air then escapes through apertures at the roof's peak. Since Plano roofing professionals are familiar with the different types of available roof vents, they can offer advice to customers about the best choices for their homes. These valuable roofing components are categorized as either intake or exhaust vents.
At the eaves, intake vents allow fresh air to enter from the outdoors. When used in conjunction with ridge vents, they utilize the benefits of natural convection to create a constant flow. Most soffit vents are individual and fit between the joists. Others, on the other hand, are continuous and run the length of the soffit. Regardless of the style, the vents must block precipitation from getting into the attic.

They must also prevent insects and small animals from invading the space while still letting air flow in freely. Property owners are responsible for keeping insulation out of the way and often do so by installing baffles between rafters. If the home is gutter-free, then drip edge vents may be appropriate. This vent type, however, should be limited to warm climates so that ice damming is not an issue.
The high point of the roof is the best place for air to exit. When vents are installed along the ridge, they balance the incoming flow at the eaves with an exhaust system. Ridge vents can be purchased in a shingle-over design or in nonshingle-over form. While both styles perform the task and include a baffle, a shingle-over ridge vent usually blends in well with the other roof components. Static vents simply cover up holes in the roof at the ridge where moist air is released from the attic. For greater air movement, a turbine vent has fan blades that circulate as the wind blows. Powered vents can be used at the ridge as long as no other exhaust vents are present. Even the top of a gable end wall can accommodate a vent, although its location limits the amount of air that is permitted to escape. Gable vents sometimes have to function as both intake and exhaust mechanisms. They depend on the speed and direction of the wind for their effectiveness.
