Ridge vents are a type of ventilation system installed along the ridge line of a roof to allow hot and humid air to escape from the attic space. There are a few common types of ridge vents:
1. Ridge Vent with External Baffles
This type of ridge vent features a design with external baffles or louvers. These baffles or louvers allow air to flow out of the attic while preventing the entry of rain, snow, or insects. They are typically made of durable materials like aluminum or plastic.
2. Ridge Vent with Internal Baffles
In this design, the baffles or channels for air circulation are located on the underside of the ridge vent. The internal baffles serve a similar purpose to external baffles, directing the air upwards and out of the attic while providing protection against weather elements.
3. Roll Ridge Vent
A roll ridge vent is a continuous strip of ventilation material that is rolled out along the ridge of the roof. It is typically made of a breathable material such as a polyester or fiberglass mesh. Roll ridge vents allow for continuous airflow along the entire length of the ridge.
4. Shingle Over Ridge Vent
Shingle over ridge vents are designed to be installed directly on top of the ridge line and are covered with shingles to blend in with the roof’s appearance. They offer a low-profile and aesthetically pleasing ventilation option while effectively exhausting hot air from the attic.
It’s important to note that different manufacturers may have specific designs and variations of ridge vents, so the availability and features may vary. When choosing a ridge vent, it’s essential to consider factors such as the climate, roof design, and the specific ventilation requirements of your home. Consulting with a professional roofer or ventilation specialist can help determine the most suitable type of ridge vent for your specific needs.
