Dallas Roofing: Article About Types Of Roofing Vents
The roof's ventilation system is important for a number of different reasons. It not only keeps the roof from overheating by allowing fresh, cool air to come into the attic, but it also allows moisture to circulate out of the attic in order to prevent moisture damage. If the current ventilation system is not adequate, a Dallas roofing contractor may help determine what type of vents may help. There are two main types of vents: intake vents and exhaust vents.
The most popular types of intake vents are soffit vents. The air around the soffits has been cooled due to the shade provided by the roof. When vents are installed here, they suck up the cooled air. The soffit vents can be continuous or individual vents depending on the ventilation needs of the home.
If the home does not have soffits, an alternative vent is the drip edge vent. The drip edge vents are installed along the eaves of the roof and also take advantage of air that is cooled by the roof's shadow. However, these often do not work as well as soffit vents.

Not only are they smaller, meaning they cannot suck up as much air as soffit vents, but they also can become blocked by insulation. However, they will provide the attic with cool air if no other option is available.
Ridge vents are by far the most popular exhaust vent installed on homes. This is because the vent runs along the entire length of the roof. This allows the hot, moist air to be released evenly from the attic space.
An alternative exhaust vent are off ridge vents. These vents can be found near the ridge, though multiple units are needed as they are not continuous. These vents are long and thin but still allow hot air to escape. However, they are not as effective as ridge vents.
Finally, box vents are like ridge vents except they are square and stick up out of the roofline. They also allow hot air escape and have a cap to prevent moisture from getting back into the roof. These box vents are also not as effective as ridge vents, meaning that several units on both sides of the roof are needed.
There are many different types of vents that can be used to provide adequate ventilation. If one type of vent does not work, a contractor should be able to offer an alternative.
