Gable vents are openings located at the peak of a roof, typically found in the triangular section of a building's exterior. They allow for proper ventilation in the attic space, helping to regulate temperature and moisture levels. This ventilation is essential for preventing issues like mold growth and ice dam formation during winter. These vents come in various styles and materials, including wood, vinyl, and metal. They can be designed to match the architectural style of a home while providing functional benefits. Proper installation and maintenance of gable vents contribute to the overall energy efficiency and longevity of a building.
