Which of the following is not a type of roof vent?

A louver vent is typically designed for sidewall ventilation rather than serving as a roof vent. It allows air to flow through a structure, often installed in walls or ceilings to facilitate airflow and reduce humidity. In contrast, soffit vents, ridge vents, and static vents are specifically designed for roof ventilation purposes.

Soffit vents are located under the roof's overhang and allow cool air to enter the attic space, creating a balanced airflow system. Ridge vents are installed at the peak of the roof, enabling hot air to escape, thus helping maintain temperature control in the attic. Static vents, also known as passive vents, promote airflow by allowing air to exit the roof area without the aid of a mechanical system. Each of these options plays a crucial role in proper attic ventilation, while louver vents do not fit into this category.
