Ridge vents play a crucial role in roofing systems by facilitating proper ventilation in the attic space. Their primary function is to exhaust hot air that accumulates in the attic, particularly during warm weather. This hot air can raise the temperature within the attic, leading to a range of issues including increased energy costs for cooling, degradation of roofing materials, and potential damage to the underlying structure.

By providing an effective pathway for hot air to escape, ridge vents help maintain a balanced airflow, which also contributes to reducing moisture buildup inside the attic. This is especially important in climates where humidity is a concern, as excessive moisture can lead to mold growth and wood rot.

In contrast, other options relate to functions not attributed to ridge vents. Stabilizing shingles involves ensuring that they are properly adhered and secured, which is unrelated to ventilation. Preventing snow accumulation is managed through other design elements such as roof slope and insulation. Insulating the roof pertains to materials that retain heat rather than vent air, which is not the role of ridge vents. Thus, the correct answer highlights the importance of proper ventilation in maintaining the overall health and longevity of a roofing system.
