Roof vents are critical for the long term life of your roof. Homeowners need to be aware that there are two categories and 4 types of vents that affect the longevity of the roofing materials and infrastructure of your roof. Adequate attic ventilation is one of the most important factors in maintaining a healthy roof free of mildew, mold, dry rot, ice dams and roof leaks in general.
Attic Exhaust Vents
These vents have three types: Ridge Vents, Power Vents and Static Vents. Ridge vents provide the greatest amount of venting possible for your roof because they run the entire length of the peak of your house. It is important that your attic get the most ventilation possible because the build of heat from hot summer temperatures or the furnace running all year round creates temperatures in excess of 165 degrees Fahrenheit. Once cooler temperatures set in like night time or a hard freeze, condensation forms. It can seem like a steamy rainforest in your attic.
Power Vents
Power vents use either standard electricity or solar generated power. They are installed either in the roof or the gable and have both a humidistat and a thermostat. These automatically turn on and off according to the temperature and moisture laden content of the air in the attic to prevent the buildup of hot and humid air.
Static Vents
These are stationary fans or vents like roof turbines that turn and release air according to air pressure and the force of the wind.
Attic Intake Vents
The most common type of intake vent is the soffit vent. One of the most effective system of roof vents is the combination of ridge and soffit vents.
