Keep Your Attic Insulated With a Vented Roof
Well-ventilated attics start with vented roofs. The right vents prevent damaging heat and moisture from accumulating, which protects your attic against mold and mildew. Vents also help regulate the temperature in your house, saving you money on your energy bills.
There are two types of roof vents: intake and exhaust. Intake vents are installed near the bottom of the roof and bring fresh air into the attic. Soffit vents are the most common choice for intake vents. Exhaust vents, which are installed near the top of the roof, allow air to escape. Types of exhaust vents include roof ridge vents, roof turbine vents and roof louvers. Intake and exhaust vents work together to ensure proper airflow. Check out our guide How to Install a Ridge Vent for information on adding ventilation to your attic.
Frequently Asked Questions
Q: What type of roof venting is best?
A: The best type of roof venting takes the design of your roof and attic into consideration. For many homes, soffits are the preferred style of intake vents, while ridge vents are best for exhaust. If your home’s design doesn’t allow for ridge vents, roof louvers are a popular alternative roof vent cap.
Q: What happens if a roof isn’t vented?
A: If your roof isn’t properly vented, heat and moisture can get trapped in your attic. This can facilitate the growth of dangerous mold and mildew. An improperly vented roof can also raise the temperature of your attic, which can affect your home’s energy bills.
Q: How long do roof vents last?
A: How long roof vents last depends on their materials. Plastic will generally last 10 to 15 years, while metal components can last much longer. Of course, the weather where you live is also an important factor.
