Home
As a homeowner, you want nothing but the best performance out of every aspect of your home. However, issues may occasionally occur. If you have fluctuating temperatures inside your home or your attic, you may have improper residential roofing ventilation. But what is the importance of roof ventilation?
Importance of Roof Ventilation
Although we keep everything sealed and properly insulated to prevent leaks, airflow is also important in the house, specifically on the roof and in the attic. As the warm air rises, an improperly insulated or vented home could cause problems down the line.
During summer, for example, a lack of ventilation could cause your roof decking and ceilings to overheat as heat builds up in the attic. This will result in a shorter lifespan for your exterior roofing materials and shingles because of continuous heat exposure.
Meanwhile, during winter, warm and humid air from the house rises into the attic. This humid air will cause condensation, which can result in wood damage and mold and mildew growth on the attic insulation. The warm air also melts and refreezes at the eaves, thus creating ice dams. These issues won’t occur if your roof is properly vented. You will also avoid bad indoor air quality, thus ensuring a healthier home for your loved ones.
Roof Ventilation Options
You have different options for ventilation, including the following:
1. Ridge vent – These vents are installed on the top-most part of our roof, along the ridgeline. It’s essentially a stationary hinge that coats the gaps where the two sides of a roof meet.
2. Soffit vent – This is normally installed to improve the flow of fresh air into the attic. These vents are installed at the bottom edge, under the eaves.
3. Box vent – These are low-profile boxes placed on the top of the roof to free hot air out of the attic.
4. Turbine vent – This is usually installed in homes with a windy climate. Its mechanism is to spin to push the hot air up and out.
