What is the primary function of counter batten in a roofing system?

Securing roof tiles to the foundation

Providing a surface to attach horizontal patterns

The primary function of counter batten in a roofing system is to provide a surface to attach horizontal patterns, particularly when installing roofing materials such as tiles or slates. Counter battens are typically applied horizontally over the battens that are installed vertically, creating a ventilated space and allowing for proper drainage. This arrangement also ensures that the roofing material can be secured effectively while facilitating proper airflow beneath the roofing elements.

This air circulation is critical in preventing moisture buildup, which can lead to hazards like mold and deterioration of roofing materials. While enhancing aesthetics and insulating properties are important considerations in roofing design, they aren't the direct functions of counter battens. Instead, the primary role centers on providing structural support for the roofing system's installation.
