During summer, the heat may get trapped in the attic. This may result in an increase in your utility bills due to the extra cooling that will be required. Similarly, if the moisture formed in the house accumulates in the attic, it may lead to decomposition of the wood and infestation of microbes such as mold and mildew.
The types of attics differ based on the requirements of the residential building codes. Basically, there are two types available- exhaust vents and intake vents. Exhaust vents allow the air from the house to escape out, whereas intake vents let the outside air into the house. These are the two primary types, the rest differ in structure and are categorized as follows.
These are installed in attics with high vents, mostly in the overhanging part of the roof. Soffit vents are the best option for homes that have only one type of venting. These are screened vents that protect the house from moisture and also insects and snow.
These are installed throughout the length of the peak of the roof. The volume of airflow for ridge attic vent is much more than any other fixed vent for attics. Ridge vents are screened and therefore, protect the house from insects and are effective all around the year. Ridge vent with baffles are considered more beneficial than simple ridge vents.
These come in a variety of shapes such as circular, triangular, and square. They are installed just below the roof peaks and help in protecting your home from strong winds, heavy snow, and also infestation to some extent. However, the life of these vents is lesser than the others and they do not ventilate the entire attic, but just a part of it. Therefore, if you have a smaller attic gable, these may work for your home.
These are cost-effective and as the name suggests, make use of solar energy to enable ventilation. Solar attic fans are charged up by solar energy and maintain a balanced airflow in the house. Installation charges are all that may cost you and will effectively reduce your utility bills.
Attic fans are very cost-effective and installing them is easier than the other vents. Also, solar attic fan installation can be very easy and you can do it yourself.
