Roofing 101 – Importance Of Roof Ventilation

roof inspectionVentilation within your home is a very important factor. Proper airflow means better air quality. That’s the reason why homes have ventilation systems in place. Without these systems, your home would probably be too hot, smelly, and a breeding ground for mold and mildew. In your kitchen, bathroom, and living spaces, airflow is important. Ventilation is a key part in preventing bad air quality which can cause lung problems for people living in the house. The same goes for your roof. It also requires proper ventilation to maintain proper function. It’s why a roof inspection is required at least once every three years.

Reasons why your new roof should be properly ventilated

Despite putting a lot of emphasis on insulation and keeping warm air in during the winter and cold air during the summer, your house still requires ventilation. Your roof, in particular, requires adequate ventilation to prevent air from being trapped in the attic. Poor ventilation will have negative effects on your home due to trapped hot air. Here’s what happens in both summer and winter:

During the summer – when there is not enough ventilation, your attic will heat up, pushing up the temperatures of your ceiling and roof decking. Your shingles will also receive consequences of hot air trapped in the attic as it ages faster than usual. Also, your HVAC system will work harder as the heat buildup in the attic transfers to the interior of the house.

During the winter – without proper ventilation, warm, moist air will rise up to the attic. This is then followed by condensation putting the interior of the roof at risk of rot and increase the risk of mold and mildew growth. Finally, ice dams form due to the warm air in the attic that is causing the snow to melt.

Options for roof ventilation

There are a number of roofing ventilation solutions that you can choose from. Ask your local roofing contractor about these options to learn more. Here are some of the most commonly used roofing ventilation systems for homes:

Ridge vent – this type of ventilation system is installed along the ridgeline of the roof and has a very low profile.

Soffit vent – these vents are normally used alongside ridge vents and box vents. They are primarily used to increase the flow of fresh air into the attic. Ask your roofing contractor for more information about the best type of roofing ventilation for your home.

Box vent – these are box-shaped vents placed toward the top of the roof to relieve the attic of hot air.

Turbine vent – these vents are normally used in areas where wind speeds are normally high. However, they are not that effective in areas with calm air and they are not low-profile installs.

Off-ridge vent – these are quite similar to box vents and serve the same purpose.

Gable vent – other than providing adequate ventilation for the attic, these types of vents also provide an aesthetic touch to them.

Cupola vent – these vents are normally part of the home’s architecture and work best when paired with other ventilation systems.

Power vent – this type of vent uses electric motors to effectively draw out warm air out of the attic without the need for passive ventilation.
