Attic Ventilation- Benefits And Types

Reduces energy costs- Improved air circulation helps remove warm air and reduce the temperature of the attic in the summers

. It also reduces surface temperature of the attic floors and interior ceilings. The reduced temperature in the attic keeps the ductwork, with inside air, cooler. Thus theres a reduced strain in the AC unit, reducing energy costs as well.

Increases the lifespan of the roof- When the attic heats up, the roofing underlayment beneath the roof shingles also heat up. With time, they may become brittle and ineffective. With attic ventilation, attic temperature will be normal and none of this will happen. Thus the life of your roof expands and you are saved from unnecessary repairs and replacement.

There are different types of roof venting available. Lets take a look at them:

Ridge vents- Ridge vents run the entire span of the roof peak and have shingles that blend in attractively. They are equally effective throughout the year, maximize the flow of air in the attic and ventilate the entire space evenly. They are screened against bugs and eliminate the risk of accidental blockage or covering.

Roof turbines- These use outside wind to power the spinning vent, resulting in proper airflow into and out of the attic. These systems are raised and can be seen spinning at the top of the homes and are very efficient. The turbine is linked to a fan blade. When the wind moves the turbine, the fan blade pulls hot air out by the vented turbine. These are mostly used in association with other vent types.

Soffit vents- These are installed in the overhanging portion of the roof that allows airflow into and through the attic. These are screened and down facing, designed to prevent snow, rain and insects, at the same time cooling the attic and promoting airflow to remove excess moisture.

Gable vents- Gable vents are rectangular, round, square or triangular louvered openings into the attic. The design stops rain, snow or strong wind from entering, at the same time allowing airflow into the space. They have a backing or screened material for providing protection from infestation. These are, however, less efficient than other attic types and allow airflow only in a portion of the attic.

Attic fans- These are generally incorporated with other venting types to allow proper ventilation. Fans, having an attached thermostat, automatically turn on at a certain temperature to promote ventilation.
